In the embodiment of the present application, the electronic device includes a display screen 100 and at least one pressure sensing module, where the display screen 100 has a target area; the pressure sensing module is arranged on the display screen 100, corresponds to a target area, and comprises a first deformation part 312, a second deformation part 313, a reference part 314 and a base 311, wherein the first deformation part 312, the second deformation part 313 and the reference part 314 are arranged on one side, facing the display screen, of the base 311; in the case of no force being applied to the target area, the first deformation element 312, the second deformation element 313 and the reference element are all in a first shape; under the condition that the target area is stressed, the pressure sensing module deforms and outputs a pressure signal, wherein the first deformation piece and the second deformation piece are both in the second shape, and the reference piece is in the first shape. This application embodiment is through setting up the first deformation piece 312 that is located base body 311 one side, second deformation piece 313 and reference part 314, can form half-bridge detection circuit through deformation piece and reference part, when the target area atress on the display screen 100 that corresponds with the pressure-sensitive module, display screen 100 can transmit this atress to the pressure-sensitive module, deformation in the pressure-sensitive module warp, the reference part is not out of shape, export pressure signal, because only need set up deformation piece in one side of base body 311, can be so that the thickness of pressure-sensitive module reduces, and then reduce electronic equipment's whole thickness, promote user experience.
It should be noted that the electronic device may further include a control module, when the target area is stressed, the screen transmits the stress to the pressure sensing module, the pressure sensing module deforms, and outputs the pressure signal to the control module connected to the pressure sensing module, and the control module generates a corresponding control signal according to the pressure signal to control the electronic device. The electronic equipment can also comprise components such as a functional module, a battery and the like, and the functional module can be a camera module, a flash lamp module, an auxiliary display screen module, a fingerprint module and the like.
Wherein, the pressure die set can set up on Flexible Circuit board (FPC), and the control module group sets up on the Circuit board, and FPC is connected with the Circuit board electricity, does not do the detailed description in this application of concrete connection structure, can confirm according to actual conditions.
In order to increase the sensing range of the pressure sensing module, at least one pressure sensing module can comprise a plurality of pressure sensing modules, and the plurality of pressure sensing modules can be distributed at a plurality of positions of the display screen 100 at intervals, so that the sensing range covers the whole screen as far as possible, and the use experience of a user is increased.
As shown in fig. 3, in one possible embodiment of the present application, at least one of the pressure-sensing modules may include a first pressure-sensing module 310 and a second pressure-sensing module 320 that are spaced apart from each other.
In the embodiment of the application, the sensing range in a larger range can be realized through the two pressure sensing modules, so that the cost can be saved, and the number of electronic devices in the electronic equipment can be reduced.
The two pressure sensing modules each include a first deformation member 312, a second deformation member 313, a reference member 314 and a base 311, and the first deformation member 312, the second deformation member 313 and the reference member 314 are disposed on one side of the base 311 facing the display screen 100.
In one possible embodiment of the present application, the target area may include a first sub-target area 410 corresponding to the first pressure sensing module 310 and a second sub-target area 420 corresponding to the second pressure sensing module 320, and accordingly, the pressure signal may include a first sub-pressure signal and a second sub-pressure signal.
In the case where neither the first sub-target region 410 nor the second sub-target region 420 is subjected to a force, the first deformation member 312, the second deformation member 313, and the reference member 314 are all in the first shape; under the condition that the first sub-target area 410 is stressed and the second sub-target area 420 is not stressed, the first pressure sensing module 310 deforms and outputs a first sub-pressure signal; under the condition that the second sub-target area 420 is stressed and the first sub-target area 410 is not stressed, the second pressure sensing module 320 deforms and outputs a second sub-pressure signal.
Further, since the first pressure sensing module 310 and the second pressure sensing module 320 are both disposed on the display screen 100, when the first sub-target area 410 is stressed, the screen generates a certain amount of deformation, and the second pressure sensing module 320 is also stressed with a certain amount of force, therefore, when the first sub-target area 410 is stressed, the first deformation member 312 and the second deformation member 313 of the first pressure sensing module 310 are both changed from the first shape to the second shape, the shape of the reference member 314 of the first pressure sensing module 310 is not changed, or is the first shape, the first deformation member 312 and the second deformation member 313 of the second pressure sensing module 320 are both changed from the first shape to the third shape, and the shape of the reference member 314 of the second pressure sensing module 320 is not changed, or is the first shape. The finally output first sub-pressure signal is a pressure signal generated by synthesizing the pressure signals generated by the first pressure sensing module 310 and the second pressure sensing module 320.
If the force is small, the first deformation element 312 and the second deformation element 313 of the first pressure sensing module 310 are changed from the first shape to the third shape, and the shapes of the first deformation element 312 and the second deformation element 313 of the second pressure sensing module 320 may be unchanged. The output first sub-pressure signal is the pressure signal output by the first pressure sensing module 310.
The deformation amount of the deformation element of the first pressure sensing module 310 is greater than that of the deformation element of the second pressure sensing module 320.
Correspondingly, the stress of the second sub-target area 420 is similar to the stress of the first sub-target area 410, and the text is simplified and will not be described again.
The deformation amount of the deformation element of the second pressure-sensitive module 320 is greater than that of the deformation element of the first pressure-sensitive module 310.
Through the deformation condition of above-mentioned deformation piece, the control module group can confirm the pressure signal of first pressure sensing module 310 and the output of second pressure sensing module 320, and then through this pressure signal control electronic equipment, the different positions atress of display screen 100, or the atress size is different, the pressure signal that first pressure sensing module 310 and the output of second pressure sensing module 320 that the control module group determined is also different, consequently, can realize multiple man-machine interaction mode, satisfy user's different demands. Simultaneously, because only need can determine the size of pressure through setting up deformation piece and the benchmark piece in base member 311 one side, consequently can be so that the thickness of pressure sense module at the perpendicular to display screen is less, and then makes electronic equipment's whole thickness reduce, promotes user experience.
As shown in fig. 4, in one possible embodiment of the present application, the first pressure sensing module 310 and the second pressure sensing module 320 are distributed along the length direction of the display screen 100.
That is, the first pressure sensing module 310 has a strip structure, so that the sensing range of the first pressure sensing module 310 covers a larger area.
Optionally, the first pressure sensing module 310 and the second pressure sensing module 320 are disposed in the center of the display screen 100.
That is, in order to make the sensing range that first pressure sensing module 310 and second pressure sensing module 320 sensed bigger, can set up first pressure sensing module 310 and second pressure sensing module 320 in the central position of display screen 100, be about to two pressure sensing modules set up the same in the distance to two long edges of display screen 100, and the same position in the distance to two short edges of display screen 100.
As shown in fig. 5, in one possible embodiment of the present application, at least one pressure sensing module may include a first pressure sensing module 310 and a second pressure sensing module 320 connected to each other.
The two pressure sensing modules each include a first deformation member 312, a second deformation member 313, a reference member 314 and a base 311, and the first deformation member 312, the second deformation member 313 and the reference member 314 are disposed on one side of the base 311 facing the display screen 100.
In this application embodiment, at least one pressure is felt the module and not only can be followed the length direction setting of display screen 100, can also follow the width direction setting of display screen 100, nevertheless because the width direction's of display screen 100 size is less, consequently can reduce the distance between two unit deformation pieces as far as to reduce the whole size of pressure and feel the module.
The distance between the two unit deformation members may be reduced by reducing the size of the base 311, or by reducing the base 311 between the two unit deformation members.
In one possible embodiment of the present application, the base 311 between the first deformation member of the first pressure sensing module 310 and the first deformation member of the second pressure sensing module 320 may be integrally formed.
That is, the base body between the first deformation member 312 of the first pressure sensing module 310 and the first deformation member 312 of the second pressure sensing module 320 can be integrally formed, that is, one base body is used for supporting the first deformation member 312 of the first pressure sensing module 310 and the first deformation member 312 of the second pressure sensing module 320, so that the overall size can be reduced, when one of the deformation members is stressed, the force can be better transmitted to the other deformation member, and the sensitivity of the pressure sensing module is further increased.
Further, as the longer the length of the base body is, when one unit is stressed, the stress on the other unit is correspondingly increased, that is, the longer the length of the base body is, the deformation can be better transmitted to the other unit, and the overall sensitivity is further improved, so that the length of the base body between the third unit and the fourth unit can be properly increased.
Further, there are two reference members, and both of the two reference members are disposed on the integrally formed base 311.
In the embodiment of the present application, since the single-layer deformation member does not need temperature compensation, the temperature influence is the same. Therefore, the two reference members 314 on the two substrates 311 at the edge can be omitted, and the two pressure sensing modules can directly multiplex the reference members for deformation detection.
As shown in fig. 6, in one possible embodiment of the present application, the target area may include a third sub-target area 430 corresponding to the first and second pressure sensing modules 310 and 320 connected to each other, and the pressure signal may include a third sub-pressure signal. The first pressure sensing module 310 and the second pressure sensing module 320 connected to each other can be regarded as a whole because of the close distance, that is, the whole of the first pressure sensing module 310 and the second pressure sensing module 320 corresponds to the third sub-target area.
The sub-target areas refer to the sensing ranges of the corresponding units, and the size of each sub-target area can be the same or different, and is determined according to specific conditions.
In the case that the third sub-target area 430 is not stressed, the first deformation member 312, the second deformation member 313 and the base 314 are all in the first shape; under the condition that the third sub-target area 430 is stressed, the third unit and the fourth unit are deformed and output a third sub-pressure signal together.
Further, since the first pressure sensing module 310 and the second pressure sensing module 320 are both disposed on the display screen 100 and the distance between the first pressure sensing module 310 and the second pressure sensing module 320 is relatively short, when the third sub-target area 430 is stressed, a certain deformation amount occurs on the screen, accordingly, the first pressure sensing module 310 and the second pressure sensing module 320 are also stressed by a certain force, and the deformation amount of the deformation member in the first pressure sensing module 310 and the second pressure sensing module 320 can be determined according to the distance between the stressed point of the third sub-target area 430 and the first pressure sensing module 310 and the second pressure sensing module 320.
Specifically, when the distance between the force point of the third sub-target area 430 and the first pressure sensing module 310 is short, the first deformable member 312 and the second deformable member 313 of the first pressure sensing module 310 change from the first shape to the fourth shape, the shape of the reference member 314 of the first pressure sensing module 310 is unchanged, the first shape is also the first shape, the first deformable member 312 and the second deformable member 313 of the second pressure sensing module 320 change from the first shape to the fifth shape, and the shape of the reference member 314 of the second pressure sensing module 320 is unchanged, or the first shape is also the first shape.
The deformation amount of the deformation element of the first pressure sensing module 310 is greater than that of the deformation element of the second pressure sensing module 320.
Correspondingly, when the distance between the stressed point of the third sub-target area 430 and the second pressure sensing module 320 is relatively short, similar to the above case, the text is considered to be concise, and further description is omitted.
The deformation amount of the deformation element of the second pressure-sensitive module 320 is greater than that of the deformation element of the first pressure-sensitive module 310.
The sensing range generated by two adjacent pressure sensing modules has a certain overlapping area, because the distance between the first pressure sensing module 310 and the second pressure sensing module 320 is short, the overlapping area is large, and the two output pressure signals are synthesized into one pressure signal, so that the finally output pressure signal is enhanced, and the sensitivity of the pressure sensing module can be improved.
Further, since the single-layer deformation member does not need temperature compensation, since the temperature influence can be approximately the same, two reference members that are farthest from each other in the first pressure sensing module 310 and the second pressure sensing module 320 can be omitted, and the deformation detection can be performed by directly using the two reference members in the middle. Specifically, as shown in fig. 7.
That is, the two pressure sensing modules both use the two reference components in the middle as a reference to form a wheatstone half-bridge detection circuit, and the specific principle and process have been described in detail in the above embodiments, and the detailed description is omitted in this embodiment in consideration of the brief introduction of text.
In a possible implementation manner of the present application, the at least one pressure sensing module includes a first pressure sensing module, a second pressure sensing module, a third pressure sensing module, and a fourth pressure sensing module, the first pressure sensing module and the second pressure sensing module are distributed along a length direction of the display screen, and the third pressure sensing module and the fourth pressure sensing module are distributed along a width direction of the display screen.
That is, the sensing range in a larger range can be realized through the four pressure sensing modules, so that the cost can be saved, and the number of electronic devices in the electronic equipment can be reduced.
The third pressure sensing module and the fourth pressure sensing module may be spaced from each other, as shown in fig. 9; however, because the size of the width direction of the display screen 100 is small, the distance between the two unit deformation members can be reduced as much as possible, so that the overall size of the pressure-sensitive module is reduced, and at the moment, the third pressure-sensitive module and the fourth pressure-sensitive module can be connected with each other, as shown in the structure shown in fig. 5, the overall size can be reduced, when one of the deformation members is stressed, the force can be better transmitted to the other deformation member, and the sensitivity of the pressure-sensitive module is increased.
