DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device in which a structure for mounting a display module and a case is devised.

[0002]

2. Description of the Related Art In a display device, particularly a display device which is required to have a large screen and a small thickness as represented by a liquid crystal display device,
2. Description of the Related Art Reduction of a portion called a frame located around a display device, that is, narrowing of a frame has been rapidly advanced.

In a conventional display device of this type, for example, a liquid crystal display device disclosed in Japanese Patent Application Laid-Open No. 9-160670, a mounting piece extending in the left and right direction is provided on the left and right side surfaces of a liquid crystal module. Is fixed to the front or rear surface of the case of the display device with screws or the like, thereby fixing the display module to the case.

[0004] However, as the frame width of the display device is further narrowed, particularly, the frame width in the left-right direction is required, it is becoming difficult to secure an area for disposing the mounting piece of the display module.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a display device having a mounting structure corresponding to a narrower frame in view of the above points. Another object is to reduce the number of parts and increase the workability of assembly.

[0006]

According to the present invention, there is provided a display device comprising a display module, a case for housing and disposing the display module, and a bracket fixed to the case, wherein the bracket is provided with the display device. A part of a hinge portion for rotatably supporting the display module, a recess is provided on an upper surface of the display module, and a projection engaging with the recess is formed on an inner surface of the case facing the recess. The display module is fixed to the case by fixing the bracket to the lower surface of the display module, and fixing the bracket to the case in a state where the projection and the recess are engaged. And

Further, the case is constituted by front and rear cases which can be divided in the thickness direction of the display module, and the display module can be fixed to the rear case.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. Here, FIG. 1 is a cross-sectional view of the display device 1,
FIG. 2 is a plan view of the display device 1 with the front case 31 removed.

A display device 1 typified by a liquid crystal display device includes:
The liquid crystal display module 2 is housed and placed in a case 3 made of metal or strong resin, and both are positioned with each other, and then fixed by a mounting structure described later. Since the display device 1 is used as a display device rotatably supported by a device (not shown) such as a personal computer or a word processor via a hinge portion 4, a bracket constituting a part of the hinge portion 4 is provided. 41, 41 are built-in.

The display module 2 includes a display unit 21
And a frame 23 made of metal or resin that covers the display unit 21 by exposing the display area 22 thereof, and has a thin structure with a thickness of about several mm. Depressions 25, 25 are formed in the upper surface 24 of the display module 2, and the lower surface 26
Are formed with screw holes 27 for mounting the bracket 41.

The case 3 is configured to secure a space for disposing the display module 2 by combining front and rear cases 31 and 32 which can be divided in the thickness direction of the display module 2. The front case 31 has an opening 33 corresponding to the display area 22 of the display module 2. The lower case 32 includes an upper surface 2 of the display module 2.
Protrusions 34, 34 that engage with the recesses 25, 25 are integrally provided on the inner surface facing the surface 4.

The brackets 41, 41 are made of metal or a strong resin, and are orthogonal to each other.
One surface, namely, a module mounting surface 41a, a case mounting surface 41b, and a bearing surface 41c are integrally provided. A screw hole corresponding to the screw hole 27 is provided on the module mounting surface 41a to fix the bracket 41 to the lower surface 26 of the display module 2 with a screw 42a or the like. A screw hole for fixing the rib 35 of the case 32 with a screw 42b or the like is provided, and a bearing for receiving the shaft 43 of the hinge part 4 is provided on the bearing surface 41c.

Next, a procedure for assembling the display device 1 will be described. First, the display module 2 is moved to its lower side 2
After the brackets 41, 41 are detachably fixed to the brackets 6 by using screws 42a, 42a and the like, they are arranged in the rear case 32. Here, the recess 25 provided on the upper side surface 24 of the display module 2 and the projection 34 of the rear case 32 are aligned, and the display module 2 is horizontally moved in the direction of the projection 34 so that the two are completely engaged. By the engagement of the recess 25 and the projection 34, the movement of the display module 2 in the upward direction, the left-right direction, and the thickness (front-back) direction can be restricted. next,
The brackets 41, 41 fixed to the display module are detachably fixed to the rear case 32 using screws 42b and the like. By this fixing, the movement in the downward direction of the display module 2 can be restricted, and the movement in the upward direction, the left-right direction, and the thickness (front-back) direction can be restricted at the same time.

Next, if necessary, the hinge shaft 43 is mounted on the bearing portion, and then the front case 31 is removably mounted on the rear case 32, thereby completing the assembly of the display device 1. At the time of repair or inspection, the disassembling operation can be performed in a procedure reverse to the above.

Since the bracket 41 constituting the hinge portion 4 provided between the apparatus and the device is also used for fixing the display module 2 and the case 3, the number of parts can be reduced and the number of assembling steps can be reduced by sharing parts. Can be reduced.
In addition, since the projections 34 are provided on the case 3 side, the thickness of the case 3 can be increased only at the projections 34, and the thickness of the case 3 can be increased compared with the case where the projections are provided on the module 2 side and the recesses on the case 3 side. Can be set thin overall. Also, the fixing position of the display module 2 and the case 3 is
By avoiding the left and right sides of the display module 2 for which the demand for narrowing the frame is strict, the upper and lower sides 24, for which the demand for narrowing the frame is relatively small
With the 26 portions, it is possible to provide a structure in which the frame of the display device 1 is narrowed in the left-right direction.

[0016]

As described above, according to the present invention, the display module and the case are fixed on each of the upper and lower side surfaces of the display module, so that the left and right frames of the display device can be narrowed. it can. In addition, since the display module and the case are fixed using a part of the components constituting the hinge portion of the display device, the number of components and the number of assembly steps can be reduced.
