Description

The present invention relates to an image display device.

  In a liquid crystal display device, a structure in which a lower end of a liquid crystal panel is supported by a panel holder is known. Further, an elastic member is disposed so as to face the front surface and the back surface of the liquid crystal panel to position the liquid crystal panel, and to prevent the liquid crystal panel from coming into contact with the frame when the liquid crystal display device is dropped or vibrated. It has been.

  When the elastic member comes into contact with the liquid crystal panel in a compressed state, a local stress is generated in the liquid crystal panel due to the force acting from the elastic member, and the light transmission characteristics are locally changed to cause display unevenness. When the liquid crystal display device is placed flat, the elastic member supports the liquid crystal panel, so that the elastic member is in a compressed state. Also, when the liquid crystal panel is pressed, the elastic member disposed on the back surface of the liquid crystal panel is compressed.

  When changing from a flat position to an installed state (the screen is almost parallel to the direction of gravity), or when the force holding the liquid crystal panel is no longer applied, the liquid crystal panel is returned to its original position by the elastic force of the elastic member. If it returns, the state in which the liquid crystal panel is stressed is eliminated. However, the cut surface of the edge (side) of the liquid crystal panel may have a polishing flaw due to chamfering, and if the friction between the polishing flaw and the panel holder is large, the liquid crystal panel may not return to its original position. is there. Then, stress remains in the liquid crystal panel, and display unevenness is not eliminated.

  In Patent Document 1, the portion where the lower edge of the liquid crystal panel contacts the panel holder is an inclined surface, so that the liquid crystal panel resists friction by its own weight when the liquid crystal display device is placed from the flat position. Then, it has been proposed to slide the inclined surface and move it forward. Here, the “front” is a direction opposite to the backlight side, that is, a direction away from an elastic member that supports the liquid crystal panel in a flat state. FIG. 8 is a cross-sectional perspective view of the liquid crystal display device described in Patent Document 1. In FIG. The liquid crystal panel 200 is sandwiched between an elastic member 301 provided on the panel holder 300 and an elastic member 101 provided on the frame 100. The panel holder 300 has an inclined surface 201 on the back side of the liquid crystal panel 200. The inclined surface 201 causes the liquid crystal panel 200 to slide down the inclined surface 201 against the friction between the chamfered portion and the panel holder 300 due to the weight of the liquid crystal panel 200, and the liquid crystal panel 200 moves in a direction away from the elastic member 301. . Thereby, the compression of the elastic member 301 that has been compressed in the flat state is released, and the elastic force of the elastic member 301 is suppressed from acting locally on the liquid crystal panel 200, and local stress is applied to the liquid crystal panel 200. Occurrence is suppressed.

JP 2010-204357 A

However, the prior art has the following problems. When the display unit of the liquid crystal display device is tilted upward by the tilt mechanism of the stand, the angle of the inclined surface 201 provided on the panel holder 300 with respect to the angle of the stand installation surface becomes small. If it does so, the force of the direction which slides down the inclined surface 201 concerning the liquid crystal panel 200 becomes small, and it becomes impossible to fully resist the friction between the chamfered portion of the end surface of the liquid crystal panel 200 and the inclined surface 201. Therefore, the liquid crystal panel 2
00 could not slide down the inclined surface 201, and the compressed state of the elastic member 301 could not be eliminated, and local stress might remain in the liquid crystal panel 200 even in the installed state.

Example 1
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view of a liquid crystal display device 1 according to an embodiment of the present invention. The liquid crystal display device 1 is supported by a stand (not shown) and installed on the installation surface. The stand may be provided with a mechanism (for example, a tilt mechanism) that tilts, rotates, and turns the liquid crystal display device 1. In that case, the user can adjust the angle of the liquid crystal display device 1 according to viewing conditions.

The liquid crystal display device 1 includes a frame 10, a liquid crystal panel 20, a panel holder 30, an optical sheet 40, a reflection sheet 50, a substrate 60, and a case 70. The frame 10 is formed of resin or metal. The panel holder 30 is made of resin, and holds and stores the liquid crystal panel 20 so as to maintain a certain space from the optical sheet 40. The optical sheet 40 diffuses light from the backlight unit 80. The reflection sheet 50 reflects light from the light source. The substrate 60 has an LED (Light Emitting Diode) or a CCFL (Cold Cathode).
A light source 61 such as Fluorescent Lamp is mounted. The case 70 houses the optical sheet 40, the reflection sheet 50, and the substrate 60. The panel holder 30, the optical sheet 40, the reflection sheet 50, the substrate 60, and the case 70 constitute a backlight unit 80, and the liquid crystal panel 20 is illuminated by the backlight unit 80.

  A plurality of light sources 61 are mounted on the substrate 60, and the substrate 60 is fixed to the case 70. On the substrate 60, the reflection sheet 50 is arranged so that light emitted from the light source 61 is efficiently diffused in the direction of the liquid crystal panel 20. The optical sheet 40 is disposed on the front surface of the reflection sheet 50, and the optical sheet 40, the reflection sheet 50, and the substrate 60 are held between the panel holder 30 and the case 70. The optical sheet 40 is a diffusion sheet for diffusing light, a lens sheet for condensing the diffused light on the front surface and increasing luminance. Light emitted from the plurality of light sources 61 passes through the optical sheet 40 and reaches the liquid crystal panel 20. The light transmitted through the liquid crystal panel 20 is observed as an image.

  FIG. 2 is a front view showing the support structure of the liquid crystal panel according to the present embodiment, and FIG. 3 is a cross-sectional view taken along the line CC of FIG. In the state where the liquid crystal display device 1 is used by being installed on the installation surface by a stand (not shown) (the display surface of the liquid crystal panel is close to the direction perpendicular to the installation surface), the (−Y) direction in FIG. It shall be close to the direction perpendicular to the installation surface (vertical direction when the installation surface is horizontal).

  FIG. 2 shows a state in which the long side of the display area 21 of the liquid crystal panel 20 is installed (installed state) parallel to the installation surface (X-axis direction), and the liquid crystal panel 20 is held and stored in the panel holder 30. It shows the state. A plurality of COFs (Chip On Film) 22 to which image signals are input are connected to the upper end portion of the liquid crystal panel 20, and the side of the lower end portion of the liquid crystal panel 20 is connected to a panel holding rib 31 that is a lower end support member of the panel holder 30. In contact. In a state where the liquid crystal display device 1 is used, the weight of the liquid crystal panel 20 is supported by the panel holder 30 via the panel holding ribs 31. There are slight gaps between the left and right ends of the liquid crystal panel 20 and the ribs 32 of the panel holder 30.

  In FIG. 2, the panel holding rib 31 exemplifies a structure that uniformly contacts the lower end side of the liquid crystal panel 20. However, the panel holding rib 31 has a structure that contacts a part of the lower end side of the liquid crystal panel 20. A plurality of ribs may be provided. In that case, a part of the side of the lower end portion of the liquid crystal panel 20 is in contact with the panel holding rib, and the other part is not in contact with the panel holding rib. The position of the liquid crystal panel 20 in the X direction is determined by the rib 32 and the panel holding rib 31.

As shown in FIG. 3, the panel holder 30 is provided with a first elastic member 12 and a second elastic member 13. The first elastic member 12 and the second elastic member 13 are opposed to the back surface (surface opposite to the display surface) of the liquid crystal panel 20.
As shown in FIG. 2, the first elastic member 12 is provided along each side of the liquid crystal panel 20 in a panel holder 30 at a position corresponding to a frame-like region around the display region 21 of the liquid crystal panel 20. As shown in FIG. 3, the first elastic member 12 is provided at a position away from the outer periphery of the liquid crystal panel 20 by a distance P toward the display area 21.
As shown in FIG. 2, the second elastic member 13 is provided in the panel holder 30 at a position corresponding to the lower region in the installed state in the frame-like region around the display region 21 of the liquid crystal panel 20. As shown in FIG. 3, the second elastic member 13 is provided at a position separated from the outer periphery of the liquid crystal panel 20 by a distance Q toward the display area 21.
The distances P and Q from the outer periphery of the liquid crystal panel 20 between the first elastic member 12 and the second elastic member 13 satisfy the relationship P> Q. The distance Q is preferably small so that the force that moves the liquid crystal panel 20 forward against the friction between the lower end of the liquid crystal panel 20 and the panel holder 30 acts efficiently. The first elastic member 12 and the second elastic member 13 are arranged substantially in parallel along the side of the liquid crystal panel 20.

  That is, two different types of elastic members, the first elastic member 12 and the second elastic member 13, are provided in the panel holder 30 at a position corresponding to the lower region of the display region 21 of the liquid crystal panel 20. FIG. 2 is a view of the liquid crystal panel 20 as viewed from the front (the frame 10 side). Actually, the first elastic member 12 and the second elastic member 13 located on the back side of the liquid crystal panel 20 are visible. Though not conceptually, the positions of the first elastic member 12 and the second elastic member 13 are indicated by hatching.

  As shown in FIG. 3, the frame 10 is provided with a third elastic member 11. The third elastic member 11 is provided so as to face the surface on the display surface side of the liquid crystal panel 20. In FIG. 2, the third elastic member 11 is not shown.

  The liquid crystal panel 20 is held and held by the frame 10 and the panel holder 30 via the first elastic member 12, the second elastic member 13, and the third elastic member 11. Thereby, it is suppressed that the liquid crystal panel 20 contacts the frame 10 when the liquid crystal panel 20 is largely displaced due to vibration or dropping. The dimension from the outer periphery of the display area 21 of the liquid crystal panel 20 to the outer periphery of the panel holder 30 or the outer periphery of the frame 10 is the width of the frame of the liquid crystal display device 1.

  The positions of the third elastic member 11 that holds the front surface of the liquid crystal panel 20 and the first elastic member 12 that holds the back surface of the liquid crystal panel 20 are any positions as long as the liquid crystal panel 20 can be held. May be. The third elastic member 11 that holds the front surface of the liquid crystal panel 20 can prevent the liquid crystal panel 20 from coming into contact with the frame 10 when the liquid crystal panel 20 is greatly displaced due to vibration or the like. It is desirable to arrange in the vicinity of the side.

  The convex amount and hardness of the first elastic member 12 and the second elastic member 13 are determined according to the position and width of the panel holding rib 31 and the shape of the liquid crystal panel 20. The convex amount is the amount of protrusion in the direction of the liquid crystal panel 20 from the panel holder 30 (leftward in FIG. 3) in the thickness direction (direction perpendicular to the liquid crystal panel 20) in an uncompressed state. The larger the convex amount, the greater the elastic force acting on the liquid crystal panel 20 when the elastic member is compressed toward the panel holder 30 by the liquid crystal panel 20. Further, the greater the hardness, the greater the elastic force acting on the liquid crystal panel 20 when the elastic member is compressed toward the panel holder 30 by the liquid crystal panel 20.

  The first elastic member 12 and the second elastic member 13 satisfy at least one of the following first relationship and second relationship with respect to the convex amount and the hardness.

The first relationship is expressed by the following equation, where A is the convex amount in the thickness direction of the first elastic member 12 and B is the convex amount in the thickness direction of the second elastic member 13.

A <B (Formula 1)

The second relationship is expressed by the following equation, where a is the hardness of the first elastic member 12 and b is the hardness of the second elastic member 13.

a <b (Formula 2)

  That is, in the liquid crystal display device of the present embodiment, among the two types of elastic members that hold the back surface of the liquid crystal panel 20, the second elastic member 13 disposed on the outer peripheral side of the liquid crystal panel 20 is on the inner peripheral side. At least one of the convex amount and the hardness is larger than the first elastic member 12 to be arranged.

  With such a configuration, when the liquid crystal display device is in a flat state, the right side of FIG. 3 is on the bottom, and the weight of the liquid crystal panel 20 is supported by the first elastic member 12 and the second elastic member 13. The first elastic member 12 and the second elastic member 13 are compressed to the same extent. In this state, the elastic force of the first elastic member 12 and the second elastic member 13 acts on the liquid crystal panel 20, and local stress is generated on the liquid crystal panel 20. When the liquid crystal display device is set in the installed state from this state, the lower side of FIG. The first elastic member 12 and the second elastic member 13 do not take up the weight of the liquid crystal panel 20, and the elastic forces of the first elastic member 12 and the second elastic member 13 respectively move the liquid crystal panel 20 forward. Acts in the direction of

  Here, the glass substrate of the liquid crystal panel 20 is formed by bonding the array substrate and the color filter substrate and fixing them with a sealing material, and then cutting from the mother glass. At the time of cutting, the cut surface of the glass is very sharp and is likely to be chipped or cracked. Therefore, it is common to chamfer the cut surface using a grindstone or the like. However, this processing tends to cause polishing scratches on the chamfered portion of the glass.

  When the liquid crystal display device 1 is in the installed state, the liquid crystal panel 20 is supported by the panel holder 30, and the lower end side of the liquid crystal panel 20 and the panel holder 30 are in contact with each other. Therefore, against the elastic force acting in the direction in which the liquid crystal panel 20 is moved forward by the first elastic member 12 and the second elastic member 13, the polishing scratches on the chamfered portion at the lower end of the liquid crystal panel 20 and the panel holder 30. The friction with it becomes resistance.

  However, in the case of the present embodiment, since the second elastic member 13 is larger in convex amount or hardness than the first elastic member 12, a larger elastic force acts on the liquid crystal panel 20 at a position closer to the friction surface. Will do. Therefore, this elastic force makes it easier for the liquid crystal panel 20 to move forward against friction. That is, when the liquid crystal display device is set in the installed state, the liquid crystal panel 20 is suppressed from being caught by the panel holder 30, local stress is suppressed from being generated in the liquid crystal panel 20, and display unevenness is preferably suppressed. can do.

  Further, in the installed state of the liquid crystal display device, a force for pressing the liquid crystal panel 20 is applied, and the liquid crystal panel 20 is moved rearward (in the direction of the backlight unit 80) by this force, and the first elastic member 12 and the second elastic member 12 are moved. There are cases where the elastic member 13 is compressed to the same extent. In this state, the elastic force of the first elastic member 12 and the second elastic member 13 acts on the liquid crystal panel 20, and local stress is generated on the liquid crystal panel 20. When the force for pressing the liquid crystal panel 20 is removed from this state, the force that is compressing the first elastic member 12 and the second elastic member 13 is not applied, and the first elastic member 12 and the second elastic member 12 are not applied. The elastic force of the member 13 acts in the direction in which the liquid crystal panel 20 is moved forward. The friction between the chamfered portion of the lower end of the liquid crystal panel 20 and the panel holder 30 becomes a resistance against this elastic force. However, as described above, the friction is caused by the elastic force of the second elastic member 13. The liquid crystal panel 20 easily moves forward. Therefore, the liquid crystal panel 20 is suppressed from being caught by the panel holder 30, the local stress is suppressed from being generated in the liquid crystal panel 20, and the occurrence of display unevenness can be preferably suppressed.

The relationship that the elastic member having a larger elastic force is disposed at a position closer to the friction surface is always established regardless of the tilt angle of the display unit or the like. Therefore, in a liquid crystal display device in which the angle of the display unit can be changed by a tilt mechanism, a swivel mechanism, a pivot mechanism, etc., it is possible to suppress the occurrence of display unevenness due to local stress regardless of the angle of the display unit. is there. The convex amount and hardness of the second elastic member 13 are such that the elastic force generated in the compressed state by supporting the weight of the liquid crystal panel 20 or pressing the liquid crystal panel 20 in a flat state is the same as that of the liquid crystal panel 20. It is set to be larger than the frictional force with the panel holding rib 31.

  As a specific example, the first elastic member 12 is made of silicon rubber and has a thickness of 2 mm, and the second elastic member 13 is made of urethane foam and has a thickness of 3 mm. The arrangement position P of the first elastic member 12 is 5 mm from the lower end of the liquid crystal panel 20, and the arrangement position Q of the second elastic member 13 is 2 mm from the lower end of the liquid crystal panel 20. In this case, it was confirmed that display unevenness generated in the liquid crystal display device 1 could be suppressed.

  In the present embodiment, the example in which the first elastic member 12 and the second elastic member 13 are rectangular has been described. However, the second elastic member 13 is more liquid crystal than the first elastic member 12. Any configuration that increases the elastic force acting on the panel 20 may be used. For example, the shape of the tip of the first elastic member 12 may be more easily crushed than the second elastic member 13.

(Example 2)
Embodiment 2 of the present invention includes a rotation mechanism for rotating the display unit around an axis perpendicular to the screen, and the position of the display unit can be switched to a plurality of positions having different angles around the axis when the liquid crystal display device is used. This is an example in which the present invention is applied to a liquid crystal display device that can be used. In the second embodiment, components equivalent to those in the first embodiment are denoted by the same names and reference numerals as those in the first embodiment, and detailed description thereof is omitted.

FIG. 4 is a front view illustrating a support structure of the liquid crystal panel 20 of the liquid crystal display device 1 according to the second embodiment.
As in the first embodiment, the liquid crystal panel 20 is held by the panel holder 30.

It has a structure that can be used at two types of positions, ie, a position (vertical position) as a direction.

  As in the first embodiment, in the panel holder 30, the panel holding rib 31 is provided at a position in contact with the side of the lower end portion of the liquid crystal panel 20, and the weight of the liquid crystal panel 20 is increased when the liquid crystal display device 1 is used in the horizontal position. It is supported by the holding rib 31. Furthermore, in the present embodiment, the panel holder 30 is provided with a panel holding rib 31 at a position in contact with the side of the right end portion of the liquid crystal panel 20 in the panel holder 30, and the liquid crystal panel 20 is used when the liquid crystal display device 1 is used in the vertical position. The weight is supported by the panel holding rib 31.

  About the 1st elastic member 12, as shown in FIG. 4, it is the same as that of Example 1. FIG. As shown in FIG. 4, the second elastic member 13 corresponds to the lower region when used in the horizontal position among the regions around the display region 21 of the liquid crystal panel 20 as in the first embodiment. It is provided in the panel holder 30 at the position. Further, the second elastic member 13 is also provided in the panel holder 30 at a position corresponding to a lower area (right area in FIG. 4) when used in the vertical position. The second elastic member 13 provided in the lower region when used in the vertical position is the same as the second elastic member 13 provided in the lower region when used in the horizontal position. It is provided at a position separated from the outer periphery by a distance Q.

  According to the liquid crystal display device of the present embodiment, the liquid crystal panel 20 is pushed forward by the second elastic member 13 regardless of whether it is used in the horizontal position or in the vertical position, so that it is caught by the panel holding rib 31. It is suppressed. Therefore, it is possible to suppress the occurrence of display unevenness due to local stress generated in the liquid crystal panel 20 regardless of whether it is used in the horizontal position or in the vertical position.

  In this embodiment, a liquid crystal display device having a mechanism that can rotate 90 ° clockwise around the rotation axis perpendicular to the screen has been described as an example. However, a mechanism that can rotate 90 ° counterclockwise is described. The present invention is also applicable to a liquid crystal display device having the above. In that case, the panel is held in the panel holder 30 at a position corresponding to the lower area (the left area in FIG. 4) when used in the vertical position among the areas around the display area 21 of the liquid crystal panel 20 in FIG. The rib 31 and the second elastic member 13 may be disposed. If the rotation of 90 ° or more is possible, panel holding ribs are provided at all positions where the weight of the liquid crystal panel 20 is supported by the rotation, and the second elastic member 13 is disposed at a position Q from the outer periphery of the liquid crystal panel. That's fine.

(Example 3)
The third embodiment of the present invention changes the positional relationship between the first elastic member 12 and the second elastic member 13 in the liquid crystal display device 1 of the first embodiment. FIG. 5 is a front view illustrating the support structure of the liquid crystal panel according to the third embodiment.
As in the first and second embodiments, the liquid crystal panel 20 is held by the panel holder 30. Here, it is assumed that the liquid crystal display device 1 in the installed state has the (−Y) direction in FIG. 5 as the direction of gravity.

In the panel holder 30, a plurality of panel holding ribs 31 are provided at positions where the sides of the lower end portion of the liquid crystal panel 20 are in contact. The length of each panel holding rib 31 in the X direction is shorter than the length of the lower end of the liquid crystal panel 20, and a part of the lower side of the liquid crystal panel 20 is in contact with the panel holding rib 31. . In the installed state of the liquid crystal display device, the weight of the liquid crystal panel 20 is supported by the plurality of panel holding ribs 31.
The first elastic member 12 provided in the panel holder 30 at a position corresponding to a region other than the region on the lower side in the installed state in the periphery of the display region of the liquid crystal panel 20 is the same as in the first embodiment.

  The first elastic member 12 and the second elastic member 13 are provided in the panel holder 30 at a position corresponding to the lower region in the installed state in the periphery of the display region of the liquid crystal panel 20. In the present embodiment, the second elastic member 13 is provided only at a position corresponding to the panel holding rib 31, and the first elastic member 12 is provided only at other positions. That is, as shown in FIG. 5, in the panel holder 30, the first elastic members 12 and the second elastic members 13 are alternately arranged in the lower region in the installed state around the liquid crystal panel 20. The FIG. 6 shows a DD cross-sectional view at a position where the panel holding rib 31 and the second elastic member 13 are provided in FIG. FIG. 7 is a cross-sectional view taken along line EE in FIG. 5 where the panel holding rib 31 is not provided and the first elastic member 12 is provided.

In the position shown in FIG. 6, the side of the lower end portion of the liquid crystal panel 20 is in contact with the panel holding rib 31. At this position, only the second elastic member 13 is disposed in the panel holder 30.
At the position shown in FIG. 7, the panel holding rib 31 is not provided on the panel holder 30, and therefore the side of the lower end portion of the liquid crystal panel 20 is not in contact with the panel holding rib 31. At this position, only the first elastic member 12 is disposed in the panel holder 30.

Thereby, the side of the lower end portion of the liquid crystal panel 20 and the panel holding rib 31 are in contact with each other and the liquid crystal panel 20 may be caught by the panel holding rib 31 (FIG. 7). A force that pushes the panel 20 forward acts. Thereby, the catch between the liquid crystal panel 20 and the panel holder 30 is suppressed, and local stress is suppressed from being generated in the liquid crystal panel 20. Further, in a place where the liquid crystal panel 20 is not in contact with the lower end of the liquid crystal panel 20 and the panel holding rib 31 (FIG. 6) (FIG. 6), the first elastic member 12 and the liquid crystal panel 20 Contact with the panel holder 30 is suppressed. The first elastic member 12 supports the weight of the liquid crystal panel 20 in a flat state.

  According to the liquid crystal display device of the present embodiment, the local stress is suppressed from being generated in the liquid crystal panel 20, and the same effect as in the first and second embodiments in which display unevenness is suppressed is realized with fewer elastic members. Therefore, it is advantageous in terms of cost.
