Description

  The present invention relates to a display device including a liquid crystal panel.

  Some conventional display devices change the display content by moving an actual member such as a pointer to indicate a scale. On the other hand, the display devices described in Patent Documents 1 and 2 easily realize various changes in display contents by displaying on the liquid crystal panel an image simulating the substance member.

  However, a liquid crystal panel has a physical limit in making a display image visually recognized three-dimensionally, and is disadvantageous in that it has a flat appearance as compared with a display device using a solid member. With respect to this drawback, in the display devices described in Patent Documents 1 and 2, a decoration ring as a substantial member is arranged on the front side in the viewing direction with respect to the liquid crystal panel. Since the decorative ring is visually recognized three-dimensionally, it is possible to give a sense of depth to the planar appearance of the liquid crystal panel. Therefore, the whole display device can be made to look three-dimensional by the combination of the liquid crystal panel and the decoration ring.

Japanese Patent No. 5180150 Japanese Patent No. 4787102

  However, if the substantial member is disposed just on the front side of the liquid crystal panel as described above, a sense of depth can be given only in two stages of the display content of the liquid crystal panel and the substantial member on the near side of the liquid crystal panel. . Therefore, it is not enough for the three-dimensional appearance.

  In view of the above problems, an object of the present invention is to provide a display device that has a more three-dimensional appearance by providing a sense of depth.

In order to achieve the above object, the invention described in claim 1 is a liquid crystal panel that forms a display surface on which an image is displayed, and a back that irradiates light to the liquid crystal panel from the back side that is opposite to the display surface.

Then, it is guided to the display surface transmitting member through the liquid crystal panel .

  In this way, a sense of depth can be given by the three types of the display surface substance member, the image displayed on the liquid crystal panel, and the back surface substance member. Therefore, the display device has a more three-dimensional appearance.

In order to achieve the above object, the invention described in claim 2 irradiates light from a liquid crystal panel forming a display surface on which an image is displayed and a back surface side opposite to the display surface to the liquid crystal panel. A backlight, a rear-surface-side material member that is disposed between the liquid crystal panel and the backlight and is visually recognized through the liquid crystal panel, and a magnifying lens portion that is provided on the front surface side from the display surface of the liquid crystal panel, The back side substantial member is provided through the liquid crystal panel so as to be enlarged , and the back side substantial member is a back side light guide member in which light is guided to the inside, and the back side light guide member is irradiated by the backlight. The light is guided to the magnifying lens unit through the liquid crystal panel .

  If it is set as the said structure, a back surface side substantial member will be expanded by the expansion lens part. Along with this, the distance in the depth direction between the back-side substance member and the image displayed on the liquid crystal panel is enlarged and visually recognized. Therefore, it is possible to give a sense of depth, and the display device has a more three-dimensional appearance.

(First embodiment)
As shown in FIG. 1, the meter 1 that is a vehicle display device in the present embodiment is provided between a dashboard 80 and a steering wheel 90.

  FIG. 2 is a view of the meter 1 as viewed from the front side, which is the direction of the driver. The meter 1 is roughly classified into three display areas on the left side, the center, and the right side. In the dial 16 corresponding to the left and right display areas, liquid crystal displays 14 and 15 (hereinafter referred to as LCDs 14 and 15) are provided on the back side opposite to the front side. LCD14 and LCD15 are comprised from the liquid crystal panel, the backlight, etc. In the present embodiment, the front side is referred to as the front direction, and the back side is referred to as the back direction. In the present embodiment, the side close to the center of the dial 16 in the section along the dial 16 is called the inner side, and the side close to the end of the dial 16 is called the outer side.

  A liquid crystal panel 11 is provided on the back side of the dial 16 corresponding to the display area on the center side. A backlight 21 is provided at a predetermined distance from the back side of the liquid crystal panel 11. Further, a back surface side ring member 13 is provided between the liquid crystal panel 11 and the backlight 21.

  The liquid crystal panel 11 is a TFT liquid crystal panel including a liquid crystal layer in which liquid crystal is held, a pair of electrodes disposed on both sides of the liquid crystal layer, a color filter substrate, and a pair of polarizing films. The electrode is a matrix electrode in which a row electrode and a column electrode are combined. The electrode is composed of a transparent electrode provided for each pixel, and a voltage applied to the electrode is controlled by a thin film transistor. The color filter substrate has a red filter, a green filter, and a blue filter, and each filter is arranged for each pixel (each electrode). In addition, a thin film transistor (TFT) (not shown) that turns on and off each pixel is provided. The polarizing film is a filter that transmits light that vibrates in a predetermined direction and restricts the vibration direction of the light to a predetermined direction. The pair of polarizing films are arranged so that the vibration direction is shifted by 90 degrees.

  When the backlight 21 is turned on, the liquid crystal panel 11 is irradiated with light from the back side. Thereby, the liquid crystal panel 11 is transmitted and illuminated, and an image displayed on the liquid crystal panel 11 is visually recognized by the driver. Specifically, according to the voltage applied to the electrode arranged for each pixel of the liquid crystal panel 11, the light transmittance (light transmittance) with respect to the corresponding pixel changes.

  For example, if the applied voltage is controlled so that the transmittance is maximized for all of the electrodes corresponding to the red filter, the green filter, and the blue filter, the luminance of light transmitted through each filter is maximized. As a result, the corresponding pixel is visually recognized as white. On the other hand, if the applied voltage is controlled so that the transmittance is minimized for all the electrodes corresponding to each filter, the luminance of the light transmitted through each filter is minimized. As a result, the corresponding pixel is visually recognized as black.

  In the liquid crystal panel 11, the region whose transmittance is controlled to be high as described above, the object located on the back side of the region, that is, the back side ring member 13 is visible through the liquid crystal panel 11.

  The back surface side ring member 13 is provided between the liquid crystal panel 11 and the backlight 21. And the back surface side ring member 13 is a light guide member which reflects light inside. The back side ring member 13 is made of acrylic resin or the like.

In addition, the back surface side ring member 13 is a back surface side substantial member in this embodiment, and is a back surface side light guide member.

  The back surface side ring member 13 is provided with two light receiving portions 136. The light receiving parts 136 are provided in a positional relationship facing each other. The back surface side ring member 13 is provided with a plurality of groove portions 135.

  A display surface ring member 12 is provided on the dial 16 in a region corresponding to the display surface 11a on which an image of the liquid crystal panel 11 is displayed. The display surface ring member 12 is a cylindrical member having a cavity at the center. The display surface ring member 12 is a light guide member capable of guiding light inside. The display surface ring member 12 is made of acrylic or the like. The display surface ring member 12 is a display surface substance member in the present embodiment and a display surface transmitting member. Details of the display surface ring member 12 will be described later.

  The dial 16 is provided on the front side of the LCD 14, LCD 15 and liquid crystal panel 11. The dial 16 is made of a transparent member. Therefore, the driver can visually recognize various members existing on the back side of the dial 16. The dial 16 is printed in black on a specific area. And the various members which exist in the back | inner side of the dial 16 of the area | region where black printing was given cannot be visually recognized. Specifically, in the present embodiment, the area corresponding to the LCD 14, the LCD 15, and the liquid crystal panel 11 is not printed on the dial 16. In addition, dial printing is performed so that a transparent arrow 622 is formed. The other portions are printed on the dial 16. Therefore, the driver can view the image 623 displayed on the LCD 14 even when the dial 16 is used. The driver can also visually recognize the image 623 displayed on the LCD 15 even when the dial 16 is used. The driver can also visually recognize the image 624 displayed on the liquid crystal panel 11 even when the dial 16 is used. Further, the arrow 622 is visually recognized by the driver when light is irradiated from the back side.

  FIG. 3 is a cross-sectional view of the meter 1 of FIG. 2 cut in the direction of the one-dot chain line and viewed from the direction of the arrow in FIG. That is, the figure which looked at the cross-sectional view of the meter 1 from the downward direction of the vehicle is shown.

  As shown in FIG. 3, light emitting diodes (LEDs) 221 and 222 are provided on the board 2201 on the left side of the meter 1. Therefore, when light is irradiated to the dial 16 by the LED 221 or the LED 222, a character such as an arrow 622 formed on the dial 16 is illuminated. Then, the driver can visually recognize the characters formed on the dial 16.

  Similarly, an LED 223 is provided on the substrate 2202 on the right side of the meter 1. Therefore, when light is irradiated to the dial 16 by the LED 223, a character such as an arrow 622 formed on the dial 16 can be illuminated. Then, the driver can visually recognize the characters formed on the dial 16.

  The display surface ring member 12 is provided on the dial 16 in a region corresponding to the liquid crystal panel 11. The display surface ring member 12 includes an inner surface 122 that forms a cavity, and an outer surface 124 that has a diameter longer than the diameter of the inner surface 122. Further, the inner side surface 122 and the outer side surface 124 are parallel to each other.

  The inner side surface 122 is in contact with the dial 16 at the back side inner peripheral portion 123 b which is one end. The inner side surface 122 is formed by extending the front side direction from the back side inner peripheral portion 123b.

  The outer side surface 124 is in contact with the dial 16 at the outer periphery 123 a at the back side, which is one end. And the outer side surface 124 is formed when a surface is extended in the near direction from the back side outer peripheral part 123a.

  A front front surface 121 is provided between the inner side surface 122 and the outer side surface 124 and on the near side. Further, a back surface 123 is provided between the inner surface 122 and the outer surface 124 and on the side opposite to the front surface 121. That is, the back surface 123 is provided between the inner surface 122 and the outer surface 124 and on the back side.

  Of the surfaces of the display surface ring member 12, a back surface 123 that is in contact with the dial 16 is a translucent surface. And the front surface 121 which is a surface facing a driver | operator is a translucent surface. An inner side surface 122 provided between the front hand surface 121 and the back surface 123 is covered with a cover or the like (not shown) and does not transmit light. Similarly, the outer side surface 124 provided between the front surface 121 and the back surface 123 is covered with a cover or the like and does not transmit light. Therefore, the light emitted from the liquid crystal panel 11 to the back surface 123 is emitted from the front surface 121 after reflecting the inside of the display surface ring member 12.

  Therefore, the driver can visually recognize various colors according to the transmittance of the liquid crystal panel 11 on the front surface 121 of the display surface ring member 12.

  In addition, the length of the diameter of the back side inner peripheral portion 123b that is one end in the back direction of the inner side surface 122 is shorter than the length of the diameter of the front side inner peripheral portion 121b that is one end of the front side of the inner side surface 122. It has become. Similarly, the length of the diameter of the back outer peripheral portion 123a that is one end in the back direction of the outer surface 124 is shorter than the diameter of the front outer peripheral portion 121a that is one end in the front direction.

  The back surface side ring member 13 is provided at a position facing the display surface ring member 12 through the dial 16 and the liquid crystal panel 11. Further, the back surface side ring member 13 is provided between the liquid crystal panel 11 and the backlight 21.

  The back surface side ring member 13 is configured by an inner surface 132 that forms a cavity and an outer surface 134 that has a diameter longer than the diameter of the inner surface 132.

  The inner side surface 132 is in contact with the backlight 21 at the back inner peripheral portion 133 b that is one end. The inner side surface 132 is formed by the surface extending in the front direction from the rear inner peripheral portion 133b.

  The outer side surface 134 is in contact with the backlight 21 at the back outer peripheral portion 133 a that is one end. And the outer side surface 134 is formed when a surface is extended in this direction from the back outer peripheral part 133a.

  A front hand 131 is provided between the inner side 132 and the outer side 134 and on the front side. Further, a back surface 133 is provided between the inner surface 132 and the outer surface 134 and on the side opposite to the front surface 131. That is, the back surface 133 is provided between the inner surface 132 and the outer surface 134 and on the back side.

  Of the surface of the back surface side ring member 13, the front hand surface 131 is a translucent surface in contact with the liquid crystal panel 11. And the back surface 133 which is a surface which touches the backlight 21 is a translucent surface. The inner side surface 132 provided between the front surface 131 and the back surface 133 transmits light. Similarly, the outer side surface 134 provided between the front hand surface 131 and the back surface 133 transmits light.

  Further, the length of the diameter of the back inner peripheral portion 133b that is one end in the back direction of the inner side surface 132 is shorter than the length of the diameter of the front inner peripheral portion 131b that is one end in the front direction. Similarly, the length of the diameter of the rear outer peripheral portion 133a that is one end in the rear direction of the outer surface 134 is shorter than the diameter of the front outer peripheral portion 131a that is one end in the front direction.

  Here, as described above, the back surface side ring member 13 is provided at a position facing the display surface ring member 12 via the dial 16 and the liquid crystal panel 11. More specifically, the back surface 123 of the display surface ring member 12 and the front surface 131 of the back surface side ring member 13 face each other through the dial 16 and the liquid crystal panel 11.

  Further, in the direction along the liquid crystal panel 11, the rear outer peripheral portion 123 a of the display surface ring member 12 and the front outer peripheral portion 131 a of the back surface side ring member 13 are present at the same position. Further, in the direction along the liquid crystal panel 11, the back side inner peripheral portion 123 b of the display surface ring member 12 and the front side inner peripheral portion 131 b of the back surface side ring member 13 exist at the same position.

  Therefore, the light irradiated from the backlight 21 is first irradiated to the inside of the back surface side ring member 13 through the back surface 133 of the back surface side ring member 13. Then, the light is reflected inside the back surface side ring member 13. Next, the light reflected inside the back surface side ring member 13 is emitted from the front surface 131 of the back surface side ring member 13. The light emitted from the front surface 131 is applied to the back surface 123 of the display surface ring member 12 via the liquid crystal panel 11 and the dial 16. The light irradiated from the back surface 123 is emitted from the front surface 121 after reflecting the inside of the display surface ring member 12. Finally, the light emitted from the front face 121 is visually recognized by the driver.

  Further, the backlight 21 irradiates light toward the liquid crystal panel 11 separated by a predetermined distance. Therefore, the driver can visually recognize the image displayed on the liquid crystal panel 11.

  Further, the light irradiated from the backlight 21 and guided to the display surface ring member 12 is relatively less attenuated than the light directly irradiated to the liquid crystal panel 11. Therefore, the luminance of light emitted from the front surface 131 of the display surface ring member 12 is higher than the luminance of the image displayed on the liquid crystal panel 11.

  Next, the back surface side ring member 13 will be further described with reference to FIG. The back surface side ring member 13 includes two light receiving portions 136 extending from the outer surface 134. The end face of the light receiving unit 136 in the direction extending from the outer side surface 134 is irradiated with light 1362 from an LED 1361 having RGB light emitting elements. Therefore, the light 1362 irradiated by the LED 1361 is irradiated inside the light receiving unit 136. Then, the light 1362 travels while reflecting the inside of the light receiving unit 136 and enters the inside of the back surface side ring member 13. And the light 1362 repeats reflection with respect to the outer surface 134 and the inner surface 132 of the back surface side ring member 13. A part of the light 1362 that reflects the inside of the back surface side ring member 13 is reflected by the groove 135. Of the light 1362, the light reflected by the groove 135 is emitted from the inside of the back surface side ring member 13 to the outside via the inner surface 132. The driver visually recognizes the emitted light 1362. For this reason, the driver can visually recognize the groove portion 135.

  The groove 135 is formed from two surfaces provided on the outer surface 134. Specifically, two surfaces are provided by being dug in the system direction from the outer surface 134 toward the inner surface 132. And the groove part 135 is formed in V shape by two surfaces. The angle formed by the two surfaces is 45 °. Further, a plurality of grooves 135 are provided at equal intervals on the outer surface 134 of the back surface side ring member 13.

  Further, the groove part 135 is provided so that the light 1362 is totally reflected by the groove part 135.

  Next, returning to FIG. 2, a usage example of the meter 1 will be described. In FIG. 2, the liquid crystal panel 11 displays a pointer image 624. Further, the plurality of grooves 135 are illuminated by the LEDs 1361, respectively, and are visually recognized by the driver as a scale. Further, a speed image 624 is displayed on the liquid crystal panel 11 so that the driver can visually recognize the position adjacent to the groove portion 135. Therefore, it is visually recognized as if the speedometer is displayed.

  The driver visually recognizes the display surface ring member 12 on the front side of the display surface 11a. Further, the liquid crystal panel 11 is located on the back side from the display surface ring member 12. Therefore, the image displayed on the liquid crystal panel 11 is located on the far side from the display surface ring member 12.

  Furthermore, the back surface side ring member 13 is located on the back side from the liquid crystal panel 11. Further, the front side inner peripheral portion 131 b of the back surface side ring member 13 is located on the front side of the back side inner peripheral portion 133 b of the back surface side ring member 13. That is, there is an inclination from the front side inner peripheral part 131b toward the back side inner peripheral part 133b.

  Thus, the display surface ring member 12, the liquid crystal panel 11, and the back surface side ring member 13 are located at different positions in the depth direction. Therefore, when the driver visually recognizes the display surface ring member 12, the liquid crystal panel 11, and the back surface side ring member 13, a sense of depth can be imparted. More specifically, the display surface ring member 12, the image displayed on the liquid crystal panel 11, the front side inner peripheral part 131 b, the back side inner peripheral part 133 b and the groove part 135 of the back side ring member 13 are connected to the driver. Can visually recognize a depth.

  Hereinafter, the effect of the meter 1 in this embodiment is demonstrated.

  The meter 1 includes a liquid crystal panel 11, a backlight 21, a back surface side ring member 13, and a display surface ring member 12. The liquid crystal panel 11 forms a display surface 11a on which an image 624 is displayed. The backlight 21 irradiates light toward the liquid crystal panel 11 from the back surface side opposite to the display surface 11a. The back surface side ring member 13 is disposed between the liquid crystal panel 11 and the backlight 21, and the display surface ring member 12 visually recognized through the liquid crystal panel 11 is visually recognized on the surface side from the display surface 11 a of the liquid crystal panel 11. .

  In this way, a sense of depth can be imparted by the three types of the display surface ring member 12, the image 624 displayed on the liquid crystal panel 11, and the back surface side ring member 13. Therefore, the meter 1 becomes more three-dimensional.

  Further, light is guided to the inside of the back surface side ring member 13. The display surface ring member 12 transmits light. The back surface side ring member 13 guides the light emitted from the backlight 21 to the display surface ring member 12 through the liquid crystal panel 11.

  If it does in this way, the light guide | induced to the display surface ring member 12 will be first irradiated from the backlight 21, and will trace the inside of the back surface side ring member 13. FIG. Then, the light that follows the inside of the back surface side ring member 13 is guided to the display surface ring member 12 through the liquid crystal panel 11. On the other hand, the light directly irradiated on the liquid crystal panel 11 reaches the liquid crystal panel 11 at a predetermined distance from the backlight 21. Therefore, the amount of attenuation of the light guided to the display surface ring member 12 is smaller than the light directly irradiated to the liquid crystal panel 11. On the other hand, the amount of light directly irradiated on the liquid crystal panel 11 is attenuated compared to the light guided to the display surface ring member 12. Therefore, the brightness of the display surface ring member 12 is higher than the brightness of the image 624 displayed on the liquid crystal panel 11. Accordingly, the display surface ring member 12 is emphasized compared to the image 624 displayed on the liquid crystal panel 11.

(Second Embodiment)
In the first embodiment, the display surface substance member is the display surface ring member 12. In the present embodiment, the display surface substance member is a magnifying lens portion 321. The magnifying lens portion 321 is provided on the dial 16 in a region corresponding to the display surface 11a.

  As shown in FIG. 5, the rear surface side ring member 13 is enlarged and visually recognized by the magnifying lens portion 321. The magnifying lens portion 321 is provided on the dial 16. Specifically, the end portion of the magnifying lens portion 321 is in contact with the dial 16. Further, the magnifying lens portion 321 has a shape that is convex from the dial 16 toward the front side. The magnifying lens portion 321 has a ring shape. In FIG. 5, a region with dots is a region where the magnifying lens unit 321 is provided.

  Further, the light emitted from the inside of the back surface side ring member 13 is applied to the magnifying lens portion 321 through the liquid crystal panel 11.

  6 is a view of FIG. 5 taken along the alternate long and short dash line and viewed from the direction of the arrow.

  The magnifying lens portion 321 is provided so as to face the back surface side ring member 13 through the liquid crystal panel 11 and the dial 16. More specifically, the magnifying lens portion 321 is provided so as to cover the back surface side ring member 13 in the direction along the liquid crystal panel 11. More specifically, in the direction along the liquid crystal panel 11, the magnifying lens portion 321 is provided so as to cover the front side outer peripheral portion 131a, the front side inner peripheral portion 131b, and the back side inner peripheral portion 133b. . That is, in the direction along the liquid crystal panel 11, the outer side surface 134 is located on the inner side of the outer end portion of the magnifying lens portion 321. Similarly, the inner surface 132 is located outside the inner end of the magnifying lens portion 321.

  For this reason, the back surface side ring member 13 is enlarged and visually recognized by the driver. More specifically, the front side outer peripheral part 131a, the front side inner peripheral part 131b, the rear side inner peripheral part 133b and the groove part 135 are enlarged by the magnifying lens part 321 and are visually recognized by the driver.

  Further, the magnifying lens portion 321 is not provided in a region that does not face the back surface side ring member 13.

  Here, returning to FIG. 5, a usage example of the meter 1 in the present embodiment will be described. Note that the description of the same usage example as in the first embodiment is omitted. The meter 1 displays a green image on the liquid crystal panel 11 in a region corresponding to the magnifying lens unit 321. That is, an image of a green ring is displayed on the liquid crystal panel 11.

  In this way, the color of the ring image displayed on the liquid crystal panel 11 is visually recognized by the driver so as to stick to the magnifying lens unit 321.

  Hereinafter, the effect of the meter 1 in this embodiment is demonstrated.

  The meter 1 includes a liquid crystal panel 11, a backlight 21, a back surface side ring member 13, and a magnifying lens portion 321. The liquid crystal panel 11 forms a display surface 11a on which an image is displayed. The backlight 21 irradiates light toward the liquid crystal panel 11 from the back surface side opposite to the display surface 11a. The back surface side ring member 13 is disposed between the liquid crystal panel 11 and the backlight 21 and is visually recognized through the liquid crystal panel 11. The magnifying lens part 321 is provided on the surface side of the display surface 11 a of the liquid crystal panel 11. The magnifying lens portion 321 is provided so as to magnify the back surface side ring member 13 through the liquid crystal panel 11.

  In this way, the back surface side ring member 13 is enlarged by the magnifying lens portion 321. Accordingly, the distance in the depth direction between the back surface side ring member 13 and the image 624 displayed on the liquid crystal panel 11 is enlarged and visually recognized. Therefore, it becomes the meter 1 which can give a feeling of depth more and becomes a more three-dimensional appearance.

  Further, as described above, the magnifying lens portion 321 is colored with the color of the image displayed on the liquid crystal panel 11. Therefore, the magnifying lens portion 321 is visually recognized by the driver like a colored entity.

  Therefore, in the back direction, the image displayed on the magnifying lens portion 321 and the liquid crystal panel 11 and the back surface side ring member 13 are visually recognized by the driver at different positions. This can provide a sense of depth.

  Moreover, the back surface side ring member 13 is a back surface side light guide member into which light is guided. The back surface side ring member 13 guides the light emitted from the backlight 21 to the magnifying lens portion 321 through the liquid crystal panel 11.

  In this way, the light guided to the magnifying lens portion 321 is first irradiated from the backlight 21, traces the inside of the back surface side ring member 13, and is guided through the liquid crystal panel 11. On the other hand, the light directly irradiated on the liquid crystal panel 11 reaches the liquid crystal panel 11 at a predetermined distance from the backlight 21. Therefore, the amount of attenuation of the light guided to the magnifying lens unit 321 is small compared to the light directly irradiated to the liquid crystal panel 11. On the other hand, the amount of light that is directly irradiated to the liquid crystal panel 11 is attenuated as compared with the light guided to the magnifying lens unit 321. Therefore, the brightness of the magnifying lens unit 321 is higher than the brightness of the image 624 displayed on the liquid crystal panel 11. Accordingly, the magnifying lens unit 321 is emphasized compared to the image 624 displayed on the liquid crystal panel 11.
