Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention mainly relates to a display device for mounting a display element such as a liquid crystal module, which is a product having a display function for consumer and industrial equipment.

2. Description of the Related Art FIG. 2 is a cross-sectional view of a main part of a display device on which a conventional liquid crystal module is mounted. In FIG. 2, 11 is an exterior part,
The liquid crystal module (12) has an opening (13) for mounting with a very small gap. Reference numeral 14 is a nameplate having a sufficiently wide outer shape with respect to the opening portion 13, and has an adhesive layer 15 for attaching to the exterior portion 11 on the back side peripheral portion, and has elasticity such as sponge and rubber between the liquid crystal module 12 and the like. The damper 16 is interposed and fixed to the exterior portion 11 so as to cover the opening portion 13. As described above, by incorporating the damper 16 that is compressed and pressed between the liquid crystal module 12 and the name plate 14, the aperture 13 and the visible portion 17 of the liquid crystal module 12 can be partitioned. In the above-described conventional configuration, it is possible to deal with the fact that extremely small foreign matters such as lint and dust enter the visible portion 17 of the liquid crystal module 12 through the gap between the opening portion 13 and the liquid crystal module 12 and adhere thereto, but the damper 16 When the elastic body such as is compressed and pressure-contacted, when the nameplate 14 is thin, it loses the repulsive force of the damper 16 to cause floating, which easily causes poor appearance and has a problem of limited use.

The present invention solves such a conventional problem,
An object of the present invention is to provide a display device having a stable structure in terms of quality without increasing the number of parts.

Means for Solving the Problems In order to solve the above-mentioned problems, the display device of the present invention is arranged on a display element such as a liquid crystal module with an extremely small gap in an opening provided in an exterior part, and The nameplate having a sufficiently large outer diameter is arranged facing the open part of the external device, and an adhesive layer for sticking to the exterior part is provided on the peripheral portion of the back surface of the nameplate, and the inner end of the adhesive layer is The display element is provided so as to extend inside the outer shape of the display element.

With the above structure, the adhesive layer on the back side of the nameplate is exposed to the opening of the exterior part and can be spread over the liquid crystal module. It is possible to prevent dust and the like from entering the opening portion of the exterior portion and prevent it from reaching the visible portion of the display element such as the liquid crystal module.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a main part of a display device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an exterior part, which has an opening 3 for mounting the liquid crystal module 2 with a very small gap. Reference numeral 4 is a nameplate having a sufficiently large outer shape with respect to the opening portion 3, and has an adhesive layer 5 for sticking to the exterior portion 1 on the back surface peripheral portion, and the inner end surface of this adhesive layer 5 is the opening portion 3 of the opening portion 3. It reaches inside and reaches a position where it covers the upper end of the liquid crystal module 2.

In the above configuration, since the allowable dimension in the height direction of the liquid crystal module 2 itself is as large as 0.5 to 1 mm, it is impossible to eliminate the gap with the nameplate 4, but the thread to the visible portion 6 of the liquid crystal module 2 cannot be eliminated. Nameplate 4 to prevent dust and debris from entering
Since the inner end surface of the adhesive layer 5 on the back surface of the liquid crystal module 2 is provided inside the opening 3 and further inside the outer shape of the liquid crystal module 2, even if lint or dust enters from the opening 3, It becomes possible to adsorb by the adhesive layer 5, and it is possible to prevent it from reaching the visible portion 6 of the liquid crystal module 2.

Effects of the Invention As described above, according to the present invention, it is possible to prevent the entry of lint, dust, etc. by simply changing the size of the adhesive layer, and
It can be stable in quality. In addition, since no damper is used as in the past, cost can be reduced by reducing the number of parts and man-hours compared to the conventional configuration, and the situation that the nameplate floats up is avoided. it can.
