Description

Display module

The present invention relates to a display module having a plurality of display panels.

In recent years, on display devices mounted on vehicles, in addition to information related to vehicle operation, such as travel status such as travel speed, navigation information, and vehicle status such as fuel level, playback from TV and radio broadcast programs and recording media The displayed content, operation information of the audio device, and the like are also displayed.

Also, there are cases where a plurality of display panels are installed, and display panels that display according to information contents are used properly. For example, in a dashboard in a vehicle, various instruments indicating the vehicle state are displayed on a display panel built in the position of the instrument panel. In addition to navigation information and the like, video content targeted for viewing by passengers other than the driver is displayed on the display panel attached to the position on the passenger seat side.

As a conventional display device including a plurality of display panels, for example, there is one described in Patent Document 1. This display device includes a plurality of display panels, a chassis in which each display panel is mounted, and a frame that holds each display panel in each chassis. By arranging the display panels that fit in each frame, a plurality of display panels are arranged. Each large screen on the display panel constitutes one large screen.

JP 2012-63466 A

For example, when a plurality of display panels are attached to a dashboard or the like, conventionally, a display module composed of each display panel is assembled one by one to a member that becomes a design part such as a cover glass or a design panel. As a result, assembling steps for the number of display panels are always required, and there is a problem in that manufacturing efficiency is poor.

In addition, when assembling a plurality of display modules, the position of the display panel was adjusted for each display module, so that the display panel position was likely to vary. For this reason, there is a high possibility that the position of the display panel is shifted for each product, and there is a concern that the yield will deteriorate.

Furthermore, when assembling a plurality of display modules to the cover glass, a heavy display module was attached to the cover glass having low rigidity. In this case, it is necessary to support all the weights of the plurality of display modules with the cover glass, which may reduce the rigidity of the entire product.

Note that the display device described in Patent Document 1 arranges one display module composed of each display panel in order to form one large screen with each screen in a plurality of display panels. Therefore, in the same manner as described above, assembly and position adjustment for each display module are necessary.

The present invention solves the above-described problems, and an object of the present invention is to obtain a display module that can facilitate the assembly work and position adjustment of a plurality of display panels.

A display module according to the present invention includes a plurality of display panels, an intermediate frame member provided for each display panel and disposed on the back side of the display panel, and a plurality of display panels disposed on the back side of the intermediate frame member. And a rear frame member integrally formed with a frame opening corresponding to each.

According to the present invention, since the plurality of display panels can be assembled and adjusted at a time by using the rear frame member, the assembling work and the position adjustment of the plurality of display panels can be easily performed.

Since the periphery of the display surface of the display panels 3a-1 and 3b-1 is fixed to the flange portions 5a-1 and 5b-1, a non-translucent adhesive is provided for the adhesives 3a-2 and 3b-2. May be used. Further, when a front frame described later is used, the display panels 3a-1 and 3b-1 may be sandwiched between the front frame and the intermediate frame without using the adhesives 3a-2 and 3b-2.

Engagement holes 5a-2 and 5b-2 are formed in the side walls of the intermediate frames 5a and 5b.
By engaging the engaging claws 4-1 in the engaging holes 5a-2 and 5b-2, the intermediate frames 5a and 5b are engaged and fixed to the respective frame openings of the rear frame 4.
The method of fixing the intermediate frames 5a and 5b to the rear frame 4 is not limited to this. For example, the engaging claws provided in the intermediate frames 5a and 5b may be fitted into the engaging holes provided in the rear frame 4 and fixed.

In FIG. 2 and FIG. 3, description of the cover glass etc. which are the design components 2 is abbreviate | omitted.
The display module 3 is shipped as a product without the design part 2 as described above, and the design part 2 is attached in a factory where the display module 3 is delivered.

FIG. 4 is a cross-sectional view showing the conventional display modules 100a and 100b to which the cover glass 7 is attached. The display modules 100a and 100b to which the cover glass 7 is attached are positioned at the same position as the line AA in FIG. The cross section cut off by is shown. FIG. 5 is a cross-sectional view showing a process of attaching the cover glass 7 to the display modules 100a and 100b.
As shown in FIG. 4, the display modules 100a and 100b include display panels 3a-1 and 3b-1, rear frames 4a and 4b, and intermediate frames 5a and 5b.

The display panel 3a-1 is bonded and fixed to the flange portion 5a-1 of the intermediate frame 5a through the adhesive 3a-2. The rear frame 4a accommodates the backlight module 6a, and the intermediate frame 5a is attached thereto. Similarly, the display panel 3b-1 is bonded and fixed to the flange portion 5b-1 of the intermediate frame 5b via the adhesive 3b-2. The rear frame 4b accommodates the backlight module 6b, and the intermediate frame 5b is attached.

The display module 100a is bonded and fixed to the cover glass 7 via an adhesive 7a-1 as indicated by an arrow in FIG. Similarly, the display module 100b is bonded and fixed to the cover glass 7 via the adhesive 7b-1.
Thus, conventionally, since the display modules 100a and 100b are respectively attached to the cover glass 7, an assembling process for the number of display panels 3a-1 and 3b-1 has always been required. Further, it is necessary to adjust the positions of the display panels 3a-1 and 3b-1, respectively, and position variations of the display panels 3a-1 and 3b-1 are likely to occur.

In contrast, the display module 3 according to the first embodiment uses the rear frame 4 in which the frame openings corresponding to the display panels 3a-1 and 3b-1 are integrally formed.
Accordingly, the display module 3 is a single structure including the display panels 3a-1 and 3b-1. Therefore, it is possible to attach both the display panels 3a-1 and 3b-1 to the cover glass in one step of attaching the display module 3 to the cover glass.
Hereinafter, a specific example will be described.

FIG. 6 is a cross-sectional view showing the display module 3 according to Embodiment 1 to which the cover glass 7 is attached.

Since the adhesives 7a-1 and 7b-1 are disposed on the display surfaces of the display panels 3a-1 and 3b-1, for example, double-sided adhesion of an optical transparent adhesive (OCA) having the ability to transmit light A sheet is used.
In addition, the translucent protective plate in this invention is not limited to a cover glass, A resin-made protective plate may be sufficient.

As shown in FIG. 6, the display module 3 is bonded and fixed to the cover glass 7 via adhesives 7a-1 and 7b-1. Since the display panels 3a-1 and 3b-1 are attached to the cover glass 7 by this single process, the number of assembling steps can be significantly reduced as compared with the conventional configuration.

Further, the positions of these display panels 3a-1 and 3b-1 are adjusted in the rear frame 4. Therefore, it is not necessary to adjust the positions of the display panels 3a-1 and 3b-1 when they are attached to the cover glass 7. Therefore, the positional variation of the display panels 3a-1 and 3b-1 can be suppressed.

In the conventional configuration, since the display modules 100a and 100b, which are heavy objects, are attached to the cover glass 7 having low rigidity, there is a concern that the rigidity of the entire product is lowered. On the other hand, in the display module 3 according to Embodiment 1, the rigidity of the entire product can be improved by configuring the rear frame 4 with a material having high rigidity.

Next, a structure for reducing the occurrence of display unevenness on each display surface of the display panels 3a-1 and 3b-1 will be described.
FIG. 9 is a cross-sectional view showing the display module 3A according to the first modification of the first embodiment, and shows a cross section obtained by cutting the display module 3A at the same position as the line AA in FIG. FIG. 10 is an exploded sectional view showing the display module 3A of FIG.
The display module 3A includes display panels 3a-1 and 3b-1, a rear frame 4, intermediate frames 5a and 5b, backlight modules 6a and 6b, and a cover glass 7.

The periphery of the portion of the cover glass 7 where the display panels 3a-1 and 3b-1 are bonded is bonded and fixed to the flange portions 5a-3 and 5b-3 via the adhesives 3a-3 and 3b-3.
Since the periphery of the display surface of the display panels 3a-1 and 3b-1 is fixed to the flange portions 5a-3 and 5b-3, a non-translucent adhesive is applied to the adhesives 3a-3 and 3b-3. May be used.

Since the display panels 3a-1 and 3b-1 are not bonded and fixed to the flange portions 5a-1 and 5b-1, stress due to a load applied from the outside is not easily transmitted to the display panels 3a-1 and 3b-1. That is, the occurrence of display unevenness due to the distortion of the display panels 3a-1 and 3b-1 due to this stress can be reduced.

Further, in the display module 3A, the display panels 3a-1 and 3b-1 and the flange portions 5a-1 and 5b-1 are not bonded, and there is a possibility that dust or the like may enter the inside through the gap C shown in FIG. is there. Therefore, a dustproof cushion material may be provided in the gap C.
However, in order to prevent stress from being transmitted to the display panels 3a-1 and 3b-1 through the cushion material, the cushion material is composed of the display panels 3a-1 and 3b-1 and the flange portions 5a-1 and 5b-1. Attached to one side by single-sided adhesive.

FIG. 11 is a cross-sectional view showing a display module 3B according to a second modification of the first embodiment, and shows a cross section of the display module 3B taken at the same position as the line AA in FIG. FIG. 12 is an exploded sectional view showing the display module 3B of FIG.

Also, as shown in FIG. 12, engaging claws 5a-4 and 5b-4 are formed outside the side wall portions of the intermediate frames 5a and 5b.

Similarly to the display module 3, the rear frame 4 is integrally formed with frame openings corresponding to the display panels 3a-1 and 3b-1. Engaging claws 4-1 are formed on the side walls of the frame openings of the rear frame 4. Backlight modules 6a and 6b are accommodated in each frame opening. By engaging the engaging claws 4-1 in the engaging holes 5a-2 and 5b-2, the intermediate frames 5a and 5b are engaged and fixed to the respective frame openings of the rear frame 4.

The front frames 8a and 8b are components corresponding to the front frame member in the present invention, and are provided corresponding to the display panels 3a-1 and 3b-1, respectively, and are arranged on the front side of the intermediate frames 5a and 5b. . The front frames 8a and 8b are formed with flange portions 8a-1 and 8b-1 extending inwardly from the inner peripheral edge of the frame opening, and engagement holes 8a-2 and 8b-2 are formed in the side walls.

As with the display module 3, the display panels 3a-1 and 3b-1 are bonded and fixed to the cover glass 7 via adhesives 7a-1 and 7b-1.
On the other hand, unlike the display module 3, the display panels 3a-1 and 3b-1 are not bonded and fixed to the flange portions 5a-1 and 5b-1 of the intermediate frames 5a and 5b.
However, the periphery of the portion of the cover glass 7 where the display panels 3a-1 and 3b-1 are bonded is connected to the flange portions of the front frames 8a and 8b via the adhesives 3a-4 and 3b-4 as shown in FIG. It is bonded and fixed to 8a-1 and 8b-1.
Since the periphery of the display surface of the display panels 3a-1 and 3b-1 is fixed to the flange portions 8a-1 and 8b-1, a non-translucent adhesive is applied to the adhesives 3a-4 and 3b-4. May be used.

Since the display panels 3a-1 and 3b-1 are not bonded and fixed to the flange portions 8a-1 and 8b-1, stress due to a load applied from the outside is not easily transmitted to the display panels 3a-1 and 3b-1. That is, the occurrence of display unevenness due to the distortion of the display panels 3a-1 and 3b-1 due to this stress can be reduced.

In the display module 3B, the display panels 3a-1 and 3b-1 and the flange portions 5a-1 and 5b-1 are not bonded, and dust or the like may enter the gap C1 shown in FIG. For this reason, you may provide the cushioning material for dust prevention in the clearance gap C1.
However, in order to prevent stress from being transmitted to the display panels 3a-1 and 3b-1 through the cushion material, the cushion material is either the display panel 3a-1, 3b-1 or the flange portion 5a-1, 5b-1. It is attached with crab one-sided adhesive.

Further, in the display module 3B, as shown in FIG. 11, there is a possibility that dust or the like may enter the interior from the gap C2 between the display panels 3a-1, 3b-1 and the lower surfaces of the flange portions 8a-1, 8b-1. is there. For this reason, you may provide the cushioning material for dust prevention in the clearance gap C2.
However, in order to prevent stress from being transmitted to the display panels 3a-1 and 3b-1 through the cushion material, the cushion material is composed of the display panels 3a-1 and 3b-1 and the flange portions 8a-1 and 8b-1. Attached to one side by single-sided adhesive.

Next, the structure which provided the design panel 9 as the design component 2 is demonstrated.
FIG. 13 is a cross-sectional view showing a display module 3C of Modification 3 in Embodiment 1, and shows a cross section of the display module 3C cut at the same position as the AA line of FIG. FIG. 14 is an exploded sectional view showing the display module 3C of FIG.
As shown in FIG. 13, the display module 3C includes display panels 3a-1 and 3b-1, a rear frame 4A, intermediate frames 5a and 5b, backlight modules 6a and 6b, and a design panel 9.

The rear frame 4A is integrally formed with a frame opening corresponding to each of the display panels 3a-1 and 3b-1, and an engaging claw 4-1 is formed on the side wall of each frame opening. . Backlight modules 6a and 6b are accommodated in each frame opening.
Further, the rear frame 4A is formed with side walls along the outer shape surrounding all the frame openings, and the engaging claws 4A-1 are formed on the side walls.

In order to increase the rigidity of the product and obtain a heat dissipation effect, for example, a material having high rigidity and thermal conductivity such as aluminum or magnesium is used for the rear frame 4A.
However, the material of the rear frame 4A is not limited to these, and another material such as a resin may be used.

Further, like the display module 3, the intermediate frames 5a and 5b are formed with flange portions 5a-1 and 5b-1 extending inward from the inner peripheral edge of the frame opening, and the engagement holes 5a are formed on the side walls. -2 and 5b-2 are formed. By engaging the engaging claws 4-1 in the engaging holes 5a-2 and 5b-2, the intermediate frames 5a and 5b are engaged and fixed to the frame openings of the rear frame 4A.

The display panels 3a-1 and 3b-1 are adhesively fixed to the flange portions 5a-1 and 5b-1 via adhesives 3a-2 and 3b-2.
Since the periphery of the display surface of the display panels 3a-1 and 3b-1 is fixed to the flange portions 5a-1 and 5b-1, a non-translucent adhesive is provided for the adhesives 3a-2 and 3b-2. May be used.
Further, when the front frames 8a and 8b are used, the display panel may be sandwiched between the front frames 8a and 8b and the intermediate frames 5a and 5b without using the adhesives 3a-2 and 3b-2. .

The design panel 9 is a component corresponding to the panel member in the present invention, and is disposed on the display surface side of the display panels 3a-1 and 3b-1.
The design panel 9 has an opening for exposing the display surfaces of the display panels 3a-1 and 3b-1, and an engagement hole 9-1 is formed in the side wall.
By fitting the engagement claws 4A-1 of the rear frame 4A into these engagement holes 9-1, the design panel 9 is engaged and fixed to the rear frame 4A as shown in FIG.

In this way, the display module 3C can attach the design panel 9 to the rear frame 4A by a simple operation of fitting the engaging claws 4A-1 into the engaging holes 9-1.
That is, there is no need to assemble the display panels 3a-1 and 3b-1 to the design panel 9, respectively, and the number of assembling steps can be significantly reduced compared to the conventional configuration.

Note that the design panel 9 may be fixed to the intermediate frames 5a and 5b instead of the rear frame 4A. However, since the intermediate frames 5a and 5b are provided as separate members corresponding to the display panels 3a-1 and 3b-1, the rigidity as a product may be reduced.

In order to increase the rigidity of the product and obtain a heat dissipation effect, for example, a material having high rigidity and thermal conductivity such as aluminum or magnesium is used for the rear frame 4B.
In the display module 3D, heat generated in the electronic substrate 10 is radiated through the rear frame 4B. That is, the rear frame 4B functions as a heat radiating member that radiates heat generated in the attached electronic substrate 10.

Since the rear frame of the conventional display module is provided separately corresponding to each of the plurality of display panels, the position of each rear frame and the flatness of the back surface thereof vary, and it is difficult to fix the electronic substrate. Met.
On the other hand, by integrally forming the frame openings corresponding to each of the plurality of display panels like the rear frame 4B, the variation in the flatness of the position and the back surface is greatly reduced, and the electronic substrate can be easily made. Can be fixed. In addition, since the rear frame 4B is a single component, the degree of freedom in design increases compared to the conventional configuration, and the thickness can be reduced.
Furthermore, since the rear frame 4B can be used in place of the heat dissipating member mounted on the electronic substrate 10, a reduction in the number of components can be expected.

The configuration in which the heat generating component is attached to the rear frame may be applied to the display modules 3, 3A to 3C. Further, the heat generating component is not limited to the electronic substrate 10.
In order to reduce the influence of electromagnetic noise on the electronic substrate 10, a metal member may be provided on the back surface of the rear frame 4B so as to cover the electronic substrate 10.
Moreover, you may add the design components which cover the electronic substrate 10 newly.
