BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dustproof structure in a display device and a method for assembling the dustproof structure. In particular, it is possible to maintain a dustproof function for a display device against an impact such as a drop, and is expected to improve the production efficiency. The present invention relates to a dustproof structure in a display device and a method for assembling the dustproof structure.

2. Description of the Related Art An example of a dustproof structure in a conventional display device is shown in FIGS. FIG. 7 is an exploded perspective view of a dustproof structure in a conventional display device. FIG. 8 is a partial cross-sectional view of the dustproof structure in the display device shown in FIG. 7.

In the dustproof structure of the display device shown in FIG. 7, the liquid crystal 2 displays information processed by the substrate 4, and is connected to the substrate 4 via the flexible substrate 3. The substrate 4 is formed with a cutout 4a used for connection with the liquid crystal frame 11. The liquid crystal frame 11 is in close contact with a surface other than the display surface of the liquid crystal 2 and includes a claw portion 11d for connecting to the substrate 4. Here, the display surface is a surface used for displaying information from the substrate 4 on the liquid crystal 2. The connection between the frame 11 and the substrate 4 is made by fitting the cutout portion 4a and the claw portion 11d. The liquid crystal frame 11 is made of hard resin.

The double-sided tape 18 is sandwiched between the liquid crystal frame 11 and the bottom surface of the liquid crystal 2, and the liquid crystal 2 and the liquid crystal frame 11 are bonded by adhesion. Since the liquid crystal 2 is connected to the substrate 4 via the flexible substrate 3, the liquid crystal frame 11
One side 11b is lower than the height of the other side. Then, the flexible substrate 3 is brought into close contact with the upper portion of the one side portion 11b (see FIG. 8).

The front case 5 is formed with an opening 5a and a recess 5b. The front case 5 is, for example, a housing of a remote controller used in a television or the like. The screen window 6 is a transparent plate used for displaying the information displayed on the liquid crystal 2. Then, the side surface of the screen window 6 is brought into close contact with the recess 5b, and the opening 5a is covered by the screen window 6. Therefore,
The screen window 6 and the front case 5 are integrated. The cushion 19 is sandwiched between the inner surface of the front case 5 and the liquid crystal frame 11. As a result, the liquid crystal 2 is protected from dust.

The dustproof structure in the display device is assembled as described above, and its sectional view is, for example, as shown in FIG. The information displayed on the liquid crystal 2 is the front case 5.
Through the screen window 6 at. And
The cushion 19 interpolates the gap between the inner surface of the front case 5 and the liquid crystal frame 11 against the impact such as dropping, so that the liquid crystal 2 is protected against dust.

[0007]

However, in the dustproof structure of the display device shown in FIG. 7, there is a slight gap between the cushion 19 and the flexible substrate 3 on the one side 11b (FIG. 7). 8). Further, since the thickness of the cushion 19 is generally thin, if the gap becomes large due to the impact of the display device being dropped or the like, the gap between the inner surface of the front case 5 and the liquid crystal frame 11 may not be completely interpolated. That is, there is a problem in that the liquid crystal 2 is not completely protected against dust. Further, if the thickness of the cushion 19 is increased, the above problem may be solved, but there is a problem that the thickness of the display device is increased.

Further, during assembly, the cushion 19
Since the double-sided tape 18 is used in addition to the above, there is a problem that not only the number of parts is increased but also the work such as attaching work is increased, and improvement in productivity cannot be expected.

Therefore, the present invention has been made to solve the above problems, and the dustproof function for a display device can be maintained even when it is impacted by a drop or the like, and the dustproofing of a display device can be expected to improve the production efficiency. An object is to provide a method for assembling a structure and a dustproof structure.

[0041]

According to the present invention, in a dustproof structure in a display device provided with a frame that comes into close contact with a surface other than the display surface of the display, since the frame is made of a highly elastic resin, the impact such as a drop is prevented. When it occurs, the frame absorbs the impact, and the damage to the display device can be suppressed. High elasticity resin is used for silicone rubber and
It may be tan rubber.

According to the present invention, since the frame is brought into close contact with the inner surface of the case that covers the display, the display is sealed by the inner surface of the case and the frame, and the frame expands and contracts even if a shock such as a drop occurs. Thus, the display can be protected from dust by maintaining close contact with the inner surface of the case.

According to the present invention, a slit is formed on one side of the frame adjacent to the side surface of the display, and the slit sandwiches the medium used for connecting the display and the outside, so that the display is completely sealed. Thus, it is possible to solve the problem that a gap is created between the medium and the film as in the conventional technique.

In accordance with the present invention, cut at any point in one of the one side separated by a slit is formed, and the axis of the arbitrary point of one side having no slit, the side of the one that is formed cuts Since the display device rotates, the display device can be easily attached to the frame, and the productivity is improved. Also separated by slits
With an arbitrary point on both sides adjacent to one side as an axis,
If one side with the notch rotates,
However, the same effect is obtained.

According to the present invention, since the protrusion is formed above the display surface of the display in the frame and the display is fixed by the protrusion, it is necessary to adhere the frame and the display as in the conventional case. The double-sided tape is not required, the number of parts can be reduced, and the work such as sticking can be omitted. Therefore, there is an effect that the productivity is improved.

According to the present invention, since the hole for embedding the speaker or the microphone is formed in the frame, it is possible to prevent the frame from leaking the sound from the speaker or the microphone, which is necessary in the conventional technique. Since a donut-shaped cushion for preventing sound leakage is unnecessary, the number of parts can be reduced, and the productivity is improved.

According to the present invention, in a method of assembling a dustproof structure in which the surface other than the display surface of the display is closely attached to the inside of the frame, and the frame is closely attached to the inner surface of the case that covers the display, the dustproof structure is adjacent to the side surface of the display. forming a slit on one side of the frame, rotating about an arbitrary axis of one side forming a cut in any point in one side of one isolated, no slit one of one side formed cuts by the slits The display on the inner surface of the frame,
Since the medium used for connecting the display unit and the outside is sandwiched between the slits, the medium used for connecting the display unit and the outside can be inserted in the slit to completely protect the display unit from dust. There is an effect that it can be easily attached to the frame.

According to the present invention, since the projection is formed above the display surface of the display in the frame and the display is fixed by the projection, the display is fixed by the projection. In addition, since the double-sided tape for adhering the frame to the display is not required, the number of parts can be reduced, and the work such as sticking can be omitted. Therefore, there is an effect that the productivity is improved.
