Hereinafter, the control method 400 of the display device will be described in detail with reference to the display device 200 described with reference to FIG. 2.

Referring to FIG. 4, the control method 400 of the display device acquires first information indicating a user's posture (S410). The operation of step S410 may be performed through the control unit 240 and the detection unit 230. Specifically, a TOF camera (not shown) included in the sensing unit 230 emits light, for example, an infrared signal to the front of the display 210 under the control of the control unit 240, and the emitted infrared signal. It is possible to measure the time of reflection and return of the subject. Then, the control unit 240 may obtain the first information indicating the user's posture based on the result detected by the detection unit 230, for example, time information (S410). The detailed operation of step S410 will be described in detail below with reference to FIGS. 5 to 9.

5 is a view for explaining the operation of the display device according to an embodiment of the present disclosure. In FIG. 5, the same configuration as in FIG. 2 is illustrated using the same reference numerals.

Referring to FIG. 5, the user 501 may perform a document task or a predetermined task using the display device 200. For example, the user 501 may perform a predetermined task while operating the keyboard 530 while looking at the display device 200 which is the monitor of the computer. Here, the keyboard 530 may be included in the user interface 260 described above. Alternatively, the keyboard 530 may be a separate external device from the display device 200, and in this case, the keyboard 530 may be connected to the display device 200 through the input/output unit 270.

At least one sensor included in the sensing unit 230 may be a TOF camera. Hereinafter, a case where the sensing unit 230 includes a TOF camera as one sensor will be illustrated and described as an example. The TOF camera 230 may photograph the front surface of the display 210 and photograph a depth image corresponding to the front surface of the display 210. In FIG. 5, an example in which the sensing unit 230 is formed in a form attached to the stand 290 for supporting the display 210 included in the display device 200 is illustrated.

9 is a view for explaining the operation of the display device according to an embodiment of the present disclosure.

In addition, as illustrated in FIG. 9, the sensing unit 230 may be formed at the bottom of the front of the display 210 so as to photograph the posture of the user 501. Alternatively, the sensing unit 230 may be formed at a predetermined position 230-1 on the front top of the display 210 so as to photograph the posture of the user 501.

In addition, the sensing unit 230 may be disposed at various positions to photograph the front surface of the display 210 in addition to the positions shown in FIGS. 5 and 9.

The first information obtained in step S410 may obtain information indicating a distance between each of the neck and face of the user 501 from the front surface of the display 210. For example, the first information may be a depth image acquired by the sensing unit 230. In addition, the first information may include a distance between the display 210 and the neck of the user 501 calculated based on the depth image, and a distance to the face of the display 210 and the user 501.

Also, the first information may include a distance between the user's neck and face, which is a criterion for determining whether the user's posture is good or bad. Specifically, when the user's face is a posture that is more outward than the user's shoulder, it may be determined as a bad posture. That is, as the distance between the front face 502 and the face 503 below the neck increases, the user's posture can be said to be an easy posture to induce turtle neck syndrome. Accordingly, the first information may include the distance between the user's neck and the face, and the control unit 240 may determine whether to move the display 210 to correct the user's posture based on the first information.

Specifically, the controller 240 may generate a movement trajectory of the display according to the time corresponding to the user, based on the first information. In addition, the movement of the display 210 may be controlled according to the generated movement trajectory. The operation of generating the movement trajectory based on the first information will be described in detail with reference to FIG. 8 below.

8 is a flowchart illustrating in detail a first information acquisition operation among control methods of a display device.

Referring to FIG. 8, step S410 illustrated in FIG. 4 may include steps S810 to S850. Also, the operations illustrated in FIG. 8 may be performed under the control of the control unit 240 of the display device 200.

Under the control of the control unit 240, the detection unit 230 acquires a detection result from a sensor, for example, a TOF camera (S810). Specifically, the TOF camera 230 may transmit an infrared signal toward a subject, for example, a user present on the front surface of the display 210, and detect a time when the transmitted infrared signal is reflected by the user and reflected back. have.

Then, the control unit 240 may obtain the depth value of the region corresponding to the user's throat and the depth value of the region corresponding to the user's face based on the detection result in step S810 (S820 ). Specifically, the controller 240 may generate a depth image of the photographed subject based on the time detected in step S810. Specifically, the TOF camera 230 may acquire the depth value d1 up to the front face 502 of the user and the depth value d2 up to the face 503 below the user's neck (S820 ).

Subsequently, the control unit 240 considers the position difference between the TOF camera 230 and the front surface of the display 210, and based on the depth values obtained in step S820, between the front surface of the display 210 and the face of the user 501. The distance and the distance between the front of the display 210 and the neck of the user 501 may be respectively obtained (S830). Since the positions of the TOF camera 230 and the front side of the display 210 are known values, the face transformation of the front side of the display 210 and the user 501 is performed by performing coordinate transformation or distance transformation operations on the depth values d1 and d2. The distance between the front and the front of the display 210 and the neck of the user 501 may be respectively obtained.

Then, the controller 240 may obtain the distance d3 between the neck and the face of the user 501 using the distance value obtained in step S830 (S840).

In addition, the control unit 240 may generate a movement trajectory of the display 210 according to the time corresponding to the user 501 based on the distance d3 between the neck and the face of the user 501 obtained in step S840. (S850). Here, the movement trajectory represents the movement path of the display 210 over time. Specifically, the control unit 240 may generate a movement trajectory corresponding to the user's posture based on the detection result of the detection unit 230. For example, if it is determined that the user's posture is good as a result of detection by the sensing unit 230, a movement trajectory that prevents the display 210 from moving may be generated. As another example, when it is determined that the user's posture is bad as a result of the detection of the sensing unit 230, a movement trajectory corresponding to the movement of the display 210 to induce the user's neck movement may be generated.

Specifically, based on the detection result of the sensing unit 230, when the distance between the user's face and the neck is large (that is, when the user pulls the neck more forward), the distance between the user's face and the neck becomes smaller. In order to move the user's face in the direction, a movement path of the display 210 may be generated.

Referring to FIG. 4 again, the control method 400 of the display apparatus is based on the first information obtained in step S410, while the horizontal distance between the display 210 and the user 501 and the front surface of the display 210 decreases. The vertical distance between the user 501 and the front surface of the display 210 is controlled to move in the first direction 515 to be increased (S420). The operation of step S420 may be performed by the control unit 240. Specifically, the control unit 240 may control the driving unit 220 so that the display 210 moves in the first direction 515.

Here, the first direction 515 may be a diagonal direction toward the user 501 as shown in FIG. 5. As the display 210 moves in the first direction 515, the horizontal distance between the front surface of the display 210 and the user 501 is reduced, and the height of the display 210 is increased so that the front surface of the display 210 and the user 501 ) To increase the vertical distance.

In addition, the control unit 240 may control the driving unit 220 to adjust the inclination of the display 210 such that the front of the display 210 is inclined toward the user 501 as the above-described horizontal distance decreases. Referring to FIG. 5, the slope of the display 210-1 may have a larger value than the slope of the display 210.

The operation of step S430 may be performed by the control unit 240. Specifically, the control unit 240 may control the driving unit 220 so that the display 210 moves in the second direction 517. Here, the first limit value may be a value corresponding to the moving distance of the display 210 such that the distance between the surface of the display 210 and the user 501 becomes the proximity limit value. The configuration related to the proximity limit value will be described in detail below with reference to FIG. 12.

The column 612 may be inserted into the case of the driving unit 220. That is, in the plurality of columns 610, 211, and 612, the highest column 610 is a column that moves to the farthest, and the lowest column 612 can be a column that moves the shortest.

In addition, the tilt adjustment unit 221 is a first gear ratio having a fixed value, so that the gradient of the display 210 increases in proportion to the distance that the plurality of columns 610, 211, and 612 move. It may include a plurality of rotating gears. Here, a plurality of gears included in the tilt adjusting unit 221 may be referred to as a gear set. In addition, the tilt adjusting unit 221 may include a connection element connected to a bracket of the display 210. Here, the bracket of the display 210 may satisfy a common standard. In this case, the connection element included in the tilt adjustment unit 221 may have a form that can be connected to or disconnected from the bracket of the display 210 having a common standard.

In addition, the gear set included in the tilt adjustment unit 221 may be connected to the top column 610 of the distance adjustment unit 222.

Referring to FIG. 6, when all of the plurality of columns 610, 211, and 612 protrude to the maximum, the display 210 may move farthest in the first direction 515, and the plurality of columns 610, When both 211 and 612 are inserted into the case of the driving unit 220, the display 210 may move farthest in the second direction 517.

FIG. 7 shows the rear surface of the display device 200 illustrated in FIG. 6, and the same configuration as in FIG. 6 is illustrated using the same reference numerals.

In FIG. 7, a case is illustrated in which a plurality of columns 610, 211, and 612 included in the distance adjusting unit 222 are inclined at a fixed angle. Here, the degree of inclination of the plurality of columns 610, 211, and 612 included in the distance adjusting unit 222 may vary according to design specifications of the display device 200.

10 is another flowchart illustrating a method of controlling a display device according to an embodiment of the present disclosure. In addition, FIG. 10 may also be a flowchart for describing operations performed in the display device 200 or 300 according to an embodiment of the present disclosure described with reference to FIGS. 2 to 7. Accordingly, the control method 1000 of the display device according to the exemplary embodiment of the present disclosure may be performed through the display device 200 or 300 described with reference to FIGS. 2 to 3. Therefore, the control method 1000 of the display device may include features identical to those of the display device 200 or 300 described above.

In addition, in FIG. 10, the same configuration as in FIG. 4 is illustrated by using the same reference numerals, and thus a description overlapping with that in FIG. 4 is omitted.

Referring to FIG. 10, the control method 1000 of the display device may further include a step S1005 before performing the operation of step S410.

The control method 1000 of the display device may determine whether a user exists on the front surface of the display device 200 (S1005). The operation of step S1005 may be performed through the control unit 240 and the detection unit 230. Specifically, specifically, a TOF camera (not shown) included in the sensing unit 230 emits and emits light, for example, an infrared signal, to the front of the display 210 under the control of the control unit 240. The infrared signal and the time reflected by the subject can be measured and returned. Then, the control unit 240 may determine whether a user exists on the front surface of the display 210 based on the detection result of the TOF camera (not shown).

As a result of the determination in step S1005, when it is determined that a user exists on the front surface of the display device 200, specifically, the front surface of the display 210, the operation of step S410 may be performed.

Then, as a result of the determination in step S1005, if it is determined that the user does not exist in front of the display device 200, specifically, in front of the display 210, the control method 1000 of the display device may include steps S410 to S430. It can be terminated without performing an operation.

Hereinafter, with reference to FIGS. 11 and 12, operations for the movement of the display 210 performed in an embodiment of the present disclosure will be described in detail.

11 is a view for explaining a user's viewing angle. In FIG. 11, the same configuration as in FIG. 5 is illustrated using the same reference numerals.

Referring to FIG. 11, the user 501 can stare at the screen 1100 output from the display 210 and process a predetermined task. The general field of view (FOV) 1110 that the user 501 can view without turning the neck from side to side may be approximately 35 degrees in each of the left and right sides. Also, the preferred viewing area 1120, which is a suitable area for a user to view the screen, may be approximately 15 degrees from the left and right sides, respectively.

Considering the viewing angle 1110 and viewing viewing area 1120 of the user, when the user's gaze moves, the user unconsciously moves his head to view the object. Specifically, when the object having the gaze moves, the head moves at a speed corresponding to the moving speed of the object or slightly higher than the moving speed of the object for gaze pursuit.

In an embodiment of the present disclosure, when the movement of the object the user is staring at, focusing on the point in which the movement of the user's head or neck occurs to follow the gaze, the display 210 is moved to correct the user's posture. Control.

Specifically, the embodiment of the present disclosure, through its own experiment, it was found that the user's movement occurs as follows.

Specifically, when the display 210 such as a monitor moves, the user moves the neck or head to place the screen of the display 210 in the viewing suitable area 1120. Specifically, when the display 210, such as a monitor, moves in a direction closer to the user, when the viewing distance approaches the proximity threshold or less, the user 501 views the screen of the display 210 in a suitable viewing area ( 1120), the neck or head is moved in a direction away from the screen of the display 210. Here, the proximity limit value could be obtained experimentally, and was measured to be about 450 mm. However, the proximity limit value may vary depending on the size of a screen output by the display 210, a physical condition such as a user's height, and an installation height of the display 210. For example, the larger the size of the screen output by the display 210, the larger the proximity limit value may be.

In addition, the first limit value may be a value corresponding to the moving distance of the display 210 such that the distance between the front surface of the display 210 and the user 501 becomes the proximity limit value. As described above, the proximity limit value may be set to a value of 450 mm. In this case, the first limit value may be a distance that the display 210 moves to a point at which the distance 1212 between the front surface of the display 210 and the user 501 becomes 450 mm. Specifically, the first limit value is a plurality of columns (610, 611, 612) is moved from the original position (P1) to'the point where the distance between the front of the display 210 and the user 501 (1212) 450mm' Can be a distance.

12 is a diagram for describing a movement of a display according to an embodiment of the present disclosure.

Referring to FIG. 12, when the user 501 gazes at the display 210, the display 210 may move according to the movement trajectory 1240 to correct the posture of the user. Here, the original position of the display 210 may be the P1 position, and the slope 1231 of the display 210 at the P1 position may be referred to as 0 degrees.

The controller 240 is based on the first information, in the first direction 515 such that the vertical distance between the user and the front surface of the display 210 increases while the horizontal distance between the user 501 and the front surface of the display 210 decreases, The display 210 is controlled to move. Specifically, based on the detection result of the sensing unit 230, when the distance between the user's face and the neck is large (that is, when the user pulls the neck more forward), the distance between the user's face and the neck becomes smaller. In order to move the user's face in the direction, a movement path of the display 210 may be generated. For example, if the distance d3 between the user's face and the neck is greater than that of the correct posture, the display 210 may allow the user to move the face backward so that the distance d3 between the user's face and the neck becomes the correct posture. ) In the first direction. Here, the distance that the display 210 moves in the first direction (specifically, the distance that the plurality of columns 610, 611, and 612 move by the distance adjusting unit 222) is the viewing angle 1110 described in FIG. And the viewing area 1120, the user may move the face in a direction away from the display 210 to be calculated based on the position of the display 210.

Referring to FIG. 12, before the display 210 moves, the distance between the neck and the face of the user 501_1 has a d31 value. Suppose that the value of d31 can be determined by the turtle neck posture. Then, the control unit 240 of the display device 200 may cause the display 210 to move from the P1 position to the P5 along the 1240 path based on the first information indicating the user's posture. When the position of the front side of the display 210 becomes P5, the distance from the eye of the user 501_1 to the front of the display 210 may be 43 cm, and the user 501_1 faces back in accordance with the line of sight described in FIG. 11. The screen of the display 210 may be viewed by moving it.

Accordingly, when the display 210 comes to the P5 position, the distance between the neck and the face of the user 501_2 may be a d32 value. Here, the value of d32 is a value smaller than the value of d31, and may be a value that can be determined in a correct posture.

In an embodiment of the present disclosure, based on the first information indicating the user's posture, the movement of the display 210 may be controlled to guide the user to naturally move the neck or face to become the correct posture. Accordingly, it can be optimized for each individual user to induce the user's neck movement.

In addition, in an embodiment of the present disclosure, the controller 240 is proportional to the movement distance of the display 210 (specifically, the distance the plurality of columns 610, 611, and 612 move), and the tilt of the display (tilt) To increase the angle, the driving unit 220 (specifically, the tilt adjusting unit 221 may be controlled. Specifically, the control unit 240 moves the distance of the display 210 (specifically, a plurality of columns ( The driving unit 220 (specifically, the tilt adjusting unit 221) may be controlled such that the tilt angle of the display increases linearly in proportion to the distance the 610, 611, and 612 move.

Referring to FIG. 12, when the inclination of the display 210 is O degree in the P1 position, the controller 240 inclines the inclination of the display 210 in the P2 position and the inclination of the display 210 in the P3 position. In the P4 position, the inclination of the display 210 is 18 degrees, and in the P5 position, the driving unit 220 (specifically, the inclination adjustment unit 221) can be controlled so that the inclination of the display 210 is 28 degrees. That is, the controller 240 simultaneously adjusts the tilt angle of the display 210 as the display 210 moves upward, so that the display 210 faces downward as the display 210 moves upward. To tilt, the movement of the display 210 can be controlled.

As described above, by adjusting the inclination of the display 210 according to the movement of the distance of the display 210, the user can continue to stare at the screen of the display 210 without feeling discomfort.

The movement trajectory of the display 210 may be set to an experimentally optimized value.

Specifically, in an embodiment of the present disclosure, the movement of the display 210 is such that the angle 1250 formed by the path in which the display 210 moves is 30 to 60 degrees relative to the horizontal direction 1211. You can set the trajectory. Specifically, the movement trajectory of the display 210 may be set such that the angle 1250 formed by the path in which the display 210 moves is 45 to 49 degrees relative to the horizontal direction 1211.

In addition, in an embodiment of the present disclosure, the control unit 240 may control the driving unit 220 such that the display 210 moves at a first speed having a fixed value. Specifically, the speed of movement of the display 210 (specifically, the speed at which the plurality of columns 610, 611, and 612 move) may be set to satisfy a condition that the user is not aware of the movement of the display 210. . In the practice of the present disclosure, experimentally the above-described speed conditions were obtained at 2 mm/s or acceleration conditions at 10 mm/s^2. However, these speed conditions may vary depending on the screen size of the display 210, the user's body condition, and the like, and may be updated by being optimized experimentally.

That is, the control unit 240 may control the driving unit 220 such that the plurality of columns 610, 611, and 612 move at a speed of 2 mm/s or less.

According to an experiment in an embodiment of the present disclosure, the user moves the head backward by moving the neck from the point where the display 210 of the display device 200 is located at the front of the user's face, specifically, about 45 cm from the user's eye. Showed. Accordingly, the user corrected the turtle neck posture according to the movement of the display 210 and took a correct posture. Therefore, in an embodiment of the present disclosure, the display 210 may be moved in a diagonal direction toward the user's position (eg, 515) to induce the user's turtle neck posture to be corrected.

13 is another flowchart illustrating a method of controlling a display device according to an embodiment of the present disclosure. In addition, FIG. 13 may also be a flowchart for describing operations performed in the display device 200 or 300 according to the exemplary embodiment of the present disclosure described with reference to FIGS. 2 to 7. Accordingly, the control method 1300 of the display device according to the exemplary embodiment of the present disclosure may be performed through the display device 200 or 300 described with reference to FIGS. 2 to 3. Therefore, the control method 1300 of the display device may include features identical to those of the display device 200 or 300 described above.

In addition, in FIG. 13, the same configuration as in FIG. 4 is illustrated by using the same reference numerals, and thus a description overlapping with that in FIG. 4 is omitted.

Referring to FIG. 13, subsequent to step S420, the control method 1300 of the display apparatus performs a subsequent step according to a result of determining whether the distance the display 210 moves in the first direction 515 becomes a first limit value. You can proceed (S1325). The operation of step S1325 may be performed by the control unit 240. Specifically, in the control method 1300 of the display device, the display 210 continues to the first direction 515 until the distance the display 210 moves in the first direction 515 becomes the first limit value. It can be controlled to move. In addition, the control method 1300 of the display device may be configured such that when the distance the display 210 moves in the first direction 515 becomes the first limit value, the display 210 is the opposite direction of the first direction 515. It can be controlled to move in two directions (S430).

For example, until the distance 1212 between the front surface of the display 210 and the user 501 becomes 450 mm, the control method 1300 of the display device continues to move the display 210 in the first direction 515 Can be controlled. In addition, in the control method 1300 of the display device, when the display 210 moves in the first direction 515 and the distance 1212 between the front surface of the display 210 and the user 501 becomes 450 mm, the display 210 It may be controlled to move in the second direction, which is the opposite direction of the first direction 515.

In addition, subsequent to step S430, the control method 1300 of the display device may proceed to a subsequent step according to a result of determining whether the distance the display 210 moves in the second direction becomes the second limit value (S1335 ). The operation of step S1335 may be performed by the control unit 240. Here, the second limit value may be set based on a result of sensing the posture of the user 501. Also, the second limit value may be set to a value corresponding to the first limit value. For example, the second limit value may be set to the same value as the first limit value or a value below the first limit value.

Specifically, the controller 240 may control the movement of the display 210 to end when the distance the display 210 moves in the second direction becomes the second limit value. Also, the controller 240 may control the display 210 to continuously move in the second direction until the distance the display 210 moves in the second direction becomes the second limit value.

As described above, when the posture of the user 501 is corrected by moving the display 210 in the first direction, the control method 1300 of the display device is performed until the user becomes a comfortable distance in gazing at the display 210. The display 210 may be moved in a second direction.

In addition, in an embodiment of the present disclosure, the controller 240 may control the movement of the display 210 such that the display 210 repeatedly moves in the first direction and the second direction. Specifically, in order to repeatedly move in the first direction and the second direction, as a result of the determination in step S1335, when the distance the display 210 moves in the second direction becomes the second limit value, it returns to step S410 and returns to step S410 It is possible to control so that the operations of steps S420 and S430 can be performed. It is possible that the user's posture is not completely corrected with one neck movement. Accordingly, in order to induce the user's neck movement to be periodically performed, the control method 1300 of the display device may repeatedly perform the reciprocating movement of the display 210 performed in steps S420 and S430. Here, the reciprocating motion may refer to the movement of the display 210 moving in the first direction and then moving again in the second direction.

14 is another diagram for describing movement of a display according to an embodiment of the present disclosure.

As described above, the control unit 240 may generate a movement trajectory of the display according to the time corresponding to the user, based on the first information. In addition, the movement of the display 210 may be controlled according to the generated movement trajectory. Specifically, the movement trajectory may be set for each user based on the first information indicating the user's posture.

Referring to FIG. 14, the movement trajectory may have a shape of a graph 1401. In the graph 1401, the x-axis represents time, and the y-axis represents the moving distance of the display 210. That is, the y-axis may represent the entire travel distance of the plurality of columns 610, 611, and 612 included in the driving unit 220.

Referring to the graph 1401 shown in FIG. 14, at the origin of time 0, a plurality of columns 610, 611, and 612 included in the driving unit 220 of the display 210 overlap all in the case. It may be inserted. That is, at the origin of time 0, the total movement distance of the plurality of columns 610, 611, and 612 may be zero. Then, the display 210 may move in the first direction until the time t1. Referring to block 1450, the moving distance of the display 210 until the time t1 may be increased to D2 (eg, 220 mm). For example, the plurality of columns 610, 611, and 612 may move D2 1410 a predetermined distance from the point P0.

Subsequently, based on the time t1, the display 210 may change the movement direction from the first direction to the second direction, and move in the second direction until the time t2. Accordingly, the moving distance of the display 210 until the time t2 may be reduced to D1. Subsequently, based on the time t2, the display 210 may change the movement direction from the second direction to the first direction, and move in the first direction until the time t4. Accordingly, the moving distance of the display 210 may be increased to D3 (for example, 330 mm) until the time t4. Then, based on the time t4, the display 210 may change the movement direction from the first direction to the second direction, and move in the second direction until the time t6. Accordingly, the moving distance of the display 210 until the time t6 may be reduced to D1.

Further, according to the movement trajectory, even after the time t6, the display apparatus 200 may repeatedly perform movement in the first direction and movement in the second direction.

In the graph 1401 showing the movement trajectory illustrated in FIG. 14, the D2 value may correspond to the initial motion width 1410, and the D3 value may correspond to the maximum motion width 1420. Here, the maximum movement width 1420 is a maximum distance that the display 210 can move, and may be a movement distance corresponding to a case where each of the plurality of columns 610, 611, and 612 protrudes as much as possible.

In an embodiment of the present disclosure, the movement width of the display 210 may be gradually increased so that the user can perform neck movement naturally without feeling a burden. For example, in moving the display 210, the display 210 may be initially moved to the initial motion width 1410, and then the display 210 may be moved to the maximum motion width 1420.

15 is another flowchart illustrating a method of controlling a display device according to an embodiment of the present disclosure. In addition, FIG. 15 may also be a flowchart for describing operations performed in the display device 200 or 300 according to the exemplary embodiment of the present disclosure described with reference to FIGS. 2 to 7. Accordingly, the control method 1500 of the display device according to the exemplary embodiment of the present disclosure may be performed through the display device 200 or 300 described with reference to FIGS. 2 to 3. Therefore, the control method 1500 of the display device may include the same configuration features as the display device 200 or 300 described above.

In addition, in FIG. 15, the same configuration as in FIGS. 4 and 13 is illustrated using the same reference numerals, and thus, overlapping descriptions with those in FIGS. 4 and 13 will be omitted.

In an embodiment of the present disclosure, the control unit 240 determines whether an obstacle is present on the front surface of the display 210 based on the detection result of the detection unit 230 and displays 210 according to whether the obstacle is present ) Can be controlled.

Specifically, after the control method 1500 of the display apparatus starts the operation S420 of moving the display 210 in the first direction, the front surface of the display 210 is based on the detection result of the sensing unit 230 It may be determined whether there is an obstacle (S1525). Operation of step S1525 may be performed through the sensing unit 230 and the control unit 240. Specifically, when an object is detected within a predetermined distance from the front surface of the display 210, the control unit 240 may determine that an obstacle exists. For example, if an object is detected within 100 mm from the front of the display 210, the control unit 240 may determine that an obstacle exists.

For example, when the display 210 of the display device 200 corresponds to a monitor connected to a computer, the user 501 may be watching a computer task while drinking a beverage. In this case, the user 501 may place a glass of beverage in front of the monitor. In order to prevent the beverage cup from colliding with the beverage cup of the display 210 and the user 501 due to the movement of the display 210, an operation of step S1525 may be performed.

If there is no obstruction on the front surface of the display 210 based on the detection result of the sensing unit 230, the control method 1500 of the display device displays the moving distance in the first direction until the first limit value is reached. 210 may be moved in a first direction.

In addition, the control method 1500 of the display device, if there is an obstacle on the front of the display 210 based on the detection result of the sensing unit 230, the obstacle (for example, a drink cup) and the display 210 collide In order to prevent the display 210, the operation of step S430 may be performed to move the display 210 in a second direction that is opposite to the first direction.

In the control method 1500 of the display device, since the remaining components are the same as in FIG. 13, detailed descriptions thereof will be omitted.

16 is another flowchart illustrating a method of controlling a display device according to an embodiment of the present disclosure. In addition, FIG. 16 may also be a flowchart for describing operations performed in the display device 200 or 300 according to the exemplary embodiment of the present disclosure described with reference to FIGS. 2 to 7. Accordingly, the control method 1300 of the display device according to the exemplary embodiment of the present disclosure may be performed through the display device 200 or 300 described with reference to FIGS. 2 to 3. Therefore, the control method 1600 of the display device may include features identical to those of the display device 200 or 300 described above.

In addition, in FIG. 16, the same configuration as in FIGS. 4, 13, and 15 is illustrated by using the same reference numerals, and thus overlapping descriptions with those in FIGS. 4, 13, and 15 will be omitted.

As a result of the determination in step S1525, when it is determined that an obstacle exists, the control method 1600 of the display future may output a notification signal informing the user of the presence of the obstacle (S1625). Specifically, when it is determined that an obstacle exists, the controller 240 may control the notification unit 280 to output a notification signal informing of the presence of the obstacle. Specifically, the notification unit 280 may include at least one LED element as described above. For example, if it is determined that an obstacle is present, the controller 240 may control the red light to be output through the LED element.
