Description

  The present invention relates to a display device, and more particularly to a technique effective when applied to a display panel and a support portion for a frame member.

  Conventionally, a display device such as a television receiver or a display of a personal computer (PC) includes a liquid crystal display device using a liquid crystal display panel.

  In the liquid crystal display device, a plurality of printed circuit boards and printed wiring boards are connected to the liquid crystal display panel. For example, the liquid crystal display panel includes a frame member disposed on an outer peripheral portion of the liquid crystal display panel, A printed circuit board and a printed wiring board are fixed integrally. Further, when the liquid crystal display device is a transmissive type or a semi-transmissive type, a light source, a light diffusing plate, and the like are disposed behind the liquid crystal display panel as viewed from an observer. The frame member is integrally fixed. An example of a method for supporting the liquid crystal display panel and the light source at this time will be described with reference to FIG. FIG. 14 is a schematic cross-sectional view showing an example of a cross-sectional configuration in the outer peripheral portion of the transmissive liquid crystal display device.

  When the liquid crystal display device is a transmissive type, for example, as shown in FIG. 14, a backlight comprising a fluorescent tube 3, a reflection plate 4, a light diffusion plate 5, etc. on the back surface 1 b side of the display surface 1 a of the liquid crystal display panel 1. 2 is arranged. At this time, for example, the fluorescent tube 3 and the reflection plate 4 are fixed to the lower frame 6, and the light diffusion plate 5 and the like are disposed thereon. Further, for example, a mold frame 7 (sometimes referred to as an intermediate frame) in which resin is molded is fixed to the outer peripheral portion of the lower frame 6 by screwing or the like, and the outer periphery of the reflecting plate 4 and the light diffusing plate 5 is fixed. The part is supported by a support part 7 a of the mold frame 7 protruding between the liquid crystal display panel 1 and the light diffusion plate 5. At this time, for example, a buffer member 8 made of an elastic material is attached to the surface of the mold frame support portion 7a facing the light diffusion plate 5.

  The liquid crystal display panel 1 is supported so as to be sandwiched between an upper frame 9 facing the display surface 1a and a mold frame support 7a outside the display area. At this time, the surface of the upper frame 9 that faces the liquid crystal display panel 1, the surface of the mold frame support 7 a that faces the liquid crystal display panel 1, and the surface of the mold frame 7 that faces the outer peripheral side surface 1 c of the liquid crystal display panel 1. For example, buffer members 10, 11, and 13 made of an elastic material are attached to each.

  In addition, the liquid crystal display panel 1, the printed circuit board, the backlight 2, and the like integrated with the frame members 6, 7, and 9 are generally called liquid crystal display modules, and a liquid crystal display device such as a television receiver is manufactured. In this case, the liquid crystal display module is housed in a housing (exterior member) 12. At this time, for example, a buffer member 14 made of an elastic material is attached to the surface of the upper frame 9 facing the housing 12.

  In the liquid crystal display device, the buffer members 8, 10, 11, 13, and 14 are generally attached to the mold frame 7 and the upper frame 9 with an adhesive material, for example.

Further, in recent years, for example, positioning protrusions and spacers corresponding to the buffer members 8, 10, 11, 13, and 14 are integrally formed on the support frame corresponding to the lower frame 6, the mold frame 7, and the upper frame 9. A liquid crystal display device has been proposed (see, for example, Patent Document 1).

  In the conventional liquid crystal display device, for example, when the buffer members 8, 10, 11, 13, and 14 are attached to the mold frame 7 and the upper frame 9 with an adhesive, there is a problem that workability is poor. In particular, when the buffer member 13 is affixed to the surface of the mold frame 7 that faces the outer peripheral side surface 1c of the liquid crystal display panel 1, there is a problem that misalignment easily occurs and workability is poor.

  Further, when each of the buffer members 8, 10, 11, 13, and 14 is pasted with an adhesive material, for example, the buffer member may be distorted due to a force applied from the outside, a secular change or a decrease in the adhesive force due to heat, or the like. There has been a problem of peeling off from the frame 7 or the upper frame 9.

  Furthermore, in the case of the conventional liquid crystal display device, for example, a buffer member 10 disposed between the upper frame 9 and the liquid crystal display panel 1, and a buffer member 14 disposed between the upper frame 9 and the housing 12. Are independent members, and the buffer members 10 and 14 are affixed separately, so that the workability is poor.

  Further, in the case of the liquid crystal display device described in Patent Document 1, for example, if a shape defect or the like occurs in a positioning projection or spacer that is integrally molded, it may take time to correct the manufacturing, and manufacturing efficiency may be reduced. There is.

By doing so, the workability of the work of attaching the first buffer member to the first frame is also improved, and the workability of the assembly work of the display device is further improved.

  Further, at this time, if the display device is a liquid crystal television or the like, a third frame member that is not directly fixed to the first frame member is formed on the first frame member when viewed from the display panel.

Hereinafter, the present invention will be described in detail together with embodiments (examples) with reference to the drawings.
In all the drawings for explaining the embodiments, parts having the same function are given the same reference numerals and their repeated explanation is omitted.

1 to 3 are schematic views showing a schematic configuration of a liquid crystal display module (liquid crystal display device) of Example 1 according to the present invention.
FIG. 1 is a schematic plan view of the liquid crystal display module of Example 1 as viewed from the observer side. FIG. 2 is a schematic cross-sectional view taken along line AA ′ of FIG. FIG. 3 is a schematic exploded perspective view for explaining a mounting method of the buffer member.

  In Example 1, a transmissive liquid crystal display device is given as an example of a display device to which the present invention is applied. In a liquid crystal display module used in a transmissive liquid crystal display device, for example, as shown in FIGS. 1 and 2, a backlight 2 is disposed on the back surface 1 b side of the display surface 1 a of the liquid crystal display panel 1. For example, the backlight 2 includes a light source such as a fluorescent tube 3, a reflection plate 4, and a light diffusion plate 5. At this time, for example, the fluorescent tube 3 and the reflection plate 4 are fixed to the lower frame 6, and the light diffusion plate 5 and the like are disposed thereon. Further, for example, a mold frame 7 (sometimes referred to as an intermediate frame) in which resin is molded is fixed to the outer peripheral portion of the lower frame 6 by screwing or the like. The part is supported by a support part 7 a of the mold frame 7 protruding between the liquid crystal display panel 1 and the light diffusion plate 5. At this time, a buffer member 8 made of, for example, an elastic material is attached to the surface of the support portion 7a of the mold frame 7 that faces the light diffusing plate 5.

  The liquid crystal display panel 1 is supported so as to be sandwiched between the upper frame 9 facing the display surface 1 a and the support portion 7 a of the mold frame 7 outside the display area. At this time, for example, buffer members 10 and 11 made of an elastic material are attached to the surface of the upper frame 9 facing the liquid crystal display panel 1 and the surface of the mold frame support portion 7a facing the liquid crystal display panel 1, respectively. ing.

  At this time, the upper frame 9 is provided with an opening 9a in a region overlapping with the liquid crystal display panel 1 in a plan view, for example, as shown in FIGS. The buffer member 10 disposed between the display surface 1a of the liquid crystal display panel 1 and the upper frame 9 includes a support portion 10a between the liquid crystal display panel 1 and the upper frame 9, and an opening portion of the upper frame 9. A fixing portion 10b that protrudes from the back surface of the surface of the upper frame 9 that faces the display surface 1a of the liquid crystal display panel is provided. At this time, the buffer member 10 is fixed in position by inserting the fixing portion 10 b into the opening 9 a of the upper frame 9. At this time, if the shape of the fixed portion 9b when viewed in plan is a rectangular shape, the positioning with the opening 9a of the upper frame 9 is easy, and the buffer member is compared with the work of pasting with an adhesive material as in the past. The work of attaching 10 becomes easy. Therefore, the workability of the mounting work of the buffer member 10 is improved.

  At this time, the buffer member 10 disposed between the liquid crystal display panel 1 and the upper frame 9 has the fixing portion 10b as the opening of the upper frame 9 from the surface of the upper frame 9 facing the display surface 1a of the liquid crystal display panel 1. 9a, the area of the support 10a seen in a plane is larger than the area of the fixed part 10b seen in the plane. By doing in this way, the contact area of the buffer member 10 (support part 10a) and the liquid crystal display panel 1, and the contact area of the buffer member 10 (support part 10a) and the surface facing the liquid crystal display panel 1 of the upper frame 9 The liquid crystal display panel 1 (glass substrate) due to impact can be prevented from being damaged.

4 and 5 are schematic views for explaining another function and effect of the liquid crystal display device according to the first embodiment.
FIG. 4 is a schematic plan view illustrating an example of a liquid crystal display device in which the liquid crystal display module of Example 1 is accommodated. FIG. 5 is a schematic cross-sectional view taken along the line BB ′ of FIG. In the cross-sectional view of FIG. 5, the configuration unnecessary for explaining the other effect is omitted from the configuration of the liquid crystal display module. Further, in the cross-sectional view of FIG. 5, hatching (parallel oblique lines) indicating a cross section is partially omitted.

  The liquid crystal display module of Example 1 is a module used for a liquid crystal display device such as a liquid crystal television, for example. Usually, as shown in FIGS. 4 and 5, the inside of a housing (exterior) 12 made of a molded resin or the like. Is housed in. At this time, the outer peripheral portion of the liquid crystal display module is covered by the casing 12, but generally, the upper frame 9 and the casing 12 of the liquid crystal display module are not directly fixed. Therefore, for example, it is necessary to arrange a buffer member between the upper frame 9 and the housing 12 to avoid the opening end portion 12a of the housing 12 from hitting the liquid crystal display panel 1 due to vibration or the like.

  At this time, in the conventional liquid crystal display device, for example, as shown in FIG. 14, it is necessary to attach a new buffer member 14 to the surface of the upper frame 9 facing the housing 12.

  On the other hand, in the case of the liquid crystal display device using the liquid crystal display module of Example 1, as shown in FIG. 5, the fixing portion 10b of the buffer member 10 disposed between the liquid crystal display panel 1 and the upper frame 9 is 9 protrudes from the surface facing the housing 12. Therefore, the fixing portion 10b of the buffer member 10 can be used as a buffer member between the upper frame 9 and the housing 12, and there is no need to attach (attach) a new buffer member. As a result, the number of buffer members used can be reduced.

  FIG. 6 is a schematic cross-sectional view for explaining a first modification of the liquid crystal display module of the first embodiment. Note that the cross section shown in FIG. 6 corresponds to the cross section taken along the line A-A ′ of FIG. 1. Further, in the cross-sectional view of FIG. 6, hatching (parallel oblique lines) indicating a cross section is omitted.

  In the liquid crystal display module of the first embodiment, for example, as shown in FIG. 2, an opening 9 a is provided in the upper frame 9 and is disposed between the display surface 1 a of the liquid crystal display panel 1 and the upper frame 9. The buffer member 10 passes through a support portion 10 a disposed between the display surface 1 a of the liquid crystal display panel and the surface of the upper frame 9 facing the display surface 1 a, and the upper frame 9 through the opening 9 a of the upper frame 9. What is necessary is just the shape which has the fixing | fixed part 10b which protrudes in the back surface of the surface facing the said display surface 1a. However, although omitted in FIG. 2, for example, another buffer member is provided between the outer peripheral side surface 1c of the liquid crystal display panel 1 and the surface 7b of the mold frame 7 facing the outer peripheral side surface 1c. There is. In the conventional liquid crystal display module, since the another buffer member is attached to the mold frame 7 using, for example, an adhesive, the workability of attaching (attaching) the other buffer member is poor.

  Therefore, the liquid crystal display module according to the first embodiment includes, for example, a buffer member 10 disposed between the liquid crystal display panel 1 and the upper frame 9, and a display surface 1a and an upper frame of the liquid crystal display panel 1 as illustrated in FIG. 9 between the first support portion 10a positioned between the display surface 1a and the surface facing the display surface 1a, and the outer peripheral side surface 1c of the liquid crystal display panel 1 and the surface of the mold frame 7 facing the outer peripheral side surface 1c. A second support portion 10c may be provided. In this way, for example, the buffer member 10 disposed between the display surface 1a of the liquid crystal display panel 1 and the upper frame 9, the outer peripheral side surface 1c of the liquid crystal display panel 1 and the mold frame 7 shown in FIG. The three buffer members, that is, the buffer member 13 disposed between the two and the buffer member 14 disposed between the upper frame 9 and the housing 12 can be made into one buffer member. Therefore, the workability of the work of attaching the buffer member is improved, and the number of buffer members to be used can be reduced.

  FIG. 7 is a schematic diagram for explaining a second modification of the liquid crystal display module according to the first embodiment. FIG. 8 is a schematic diagram for explaining a third modification of the liquid crystal display module according to the first embodiment. Note that the cross sections shown in FIGS. 7 and 8 correspond to the cross section taken along the line A-A ′ of FIG. 1. Further, in the cross-sectional views of FIGS. 7 and 8, hatching (parallel oblique lines) indicating a cross section is omitted.

  In the liquid crystal display module of Example 1, for example, as shown in FIGS. 2 and 3, an opening 9 a is provided in the upper frame 9, and the fixing portion 10 a of the buffer member 10 is inserted into the opening 9 a of the upper frame 9. By fixing the position of the buffer member 10, the workability of the mounting operation of the buffer member 10 is improved and the number of buffer members to be used is reduced. In view of this, for example, as shown in FIG. 7, an opening 7 c is provided in the mold frame support 7 a between the liquid crystal display panel 1 and the light diffusion plate 5 to support the liquid crystal display panel 1 and the mold frame. If the buffer member 11 between the parts 7a is provided with a fixing part 11b that passes through the opening 7c of the mold frame and protrudes from the support part 7a of the mold frame toward the light diffusion plate 5, the fixing part 11b is fixed to the mold frame. It can be used as a buffer member 8 between the support portion 7a and the light diffusing plate 5. Therefore, the workability of attaching the buffer member 11 to the support portion 7a of the mold frame is improved, and the number of buffer members to be used can be reduced.

  Further, at this time, the buffer member 11 disposed between the mold frame support 7a and the liquid crystal display panel 1, for example, as shown in FIG. 8, the back surface 1b of the display surface 1a of the liquid crystal display panel 1 and the mold frame A first support portion 11a positioned between the support portion 7a and a second support portion positioned between the outer peripheral side surface 1c of the liquid crystal display panel 1 and the surface 7b of the mold frame 7 facing the outer peripheral side surface 1c. 11c may be provided. In this case, for example, the buffer member 11 disposed between the back surface 1b of the display surface 1a of the liquid crystal display panel 1 and the support portion 7a of the mold frame 7 and the outer periphery of the liquid crystal display panel 1 shown in FIG. The buffer member 13 disposed between the side surface 1c and the mold frame 7 and the buffer member 8 disposed between the support portion 7a of the mold frame 7 and the light diffusion plate 5 are combined into one buffer member. Can be. Therefore, the workability of the work of attaching the buffer member is improved, and the number of buffer members to be used can be reduced.

FIG. 10 is a schematic cross-sectional view taken along the line CC ′ of FIG. FIG. 11 is a schematic exploded perspective view for explaining a mounting method of the buffer member.

  In the second embodiment as well, a transmissive liquid crystal display device is cited as an example of a display device to which the present invention is applied. At this time, the overall configuration of the liquid crystal display module used in the transmissive liquid crystal display device is the same as described in the first embodiment, and thus detailed description thereof is omitted.

  The liquid crystal display module according to the second embodiment is different from the liquid crystal display module according to the first embodiment in the shape and mounting method of the buffer member 10 attached to the upper frame 9, and as shown in FIGS. 9 and 10, the upper frame 9 Instead of the opening 9a, a notch 9b with a part of the opening end opened is provided.
