Abstract

PROBLEM TO BE SOLVED: To secure wide effective display area by mounting elastic members, which press a liquid crystal display module before a housing, on the back of the liquid crystal display module in one body. SOLUTION: The liquid crystal display module 2 is constituted by arranging and fixing a liquid crystal panel and its driving circuit to a frame body in one body. When the liquid crystal display module 2 includes even a back light lighting up the liquid crystal display panel, the back light can be arranged and fixed to the frame body. The back light is combined with a light guide plate arranged on the back of the liquid crystal panel to obtain a surface type light source. On the back side of the liquid crystal display module 2, elastic members 111 for pressing the liquid crystal display module 2 against the front side of the housing 4 are mounted. Namely, the elastic members 11 are arranged in the four corners on the reverse surface of the liquid crystal display module 2 without projecting from the upper and lower, and right and left parts of the display module 2.

The shape becomes larger,
There has been a problem that the enlargement of the effective display area is hindered.

[0003]

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a liquid crystal display device capable of securing a wide effective display area and a liquid crystal display module used therefor. Another object is to improve the workability of assembling a liquid crystal display device.

[0004]

According to a first aspect of the present invention, there is provided a liquid crystal display device including a liquid crystal display module in which a liquid crystal display panel and a circuit for driving the liquid crystal panel are integrated in a housing. In the liquid crystal display device, an elastic member for pushing the liquid crystal display module toward the front of the housing is integrally mounted on a rear surface of the liquid crystal display module.

According to a second aspect of the present invention, there is provided the liquid crystal display device according to the first aspect, wherein a rib for restricting the liquid crystal display module from moving left and right and up and down is integrated with the housing. It is characterized in that it is formed in a uniform manner.

The liquid crystal display module according to the present invention is described in claim 3.
As described in the above, in a liquid crystal display module which is configured by integrating a liquid crystal display panel and a driving circuit thereof and is housed in a housing to constitute a liquid crystal display device, An elastic member is integrally mounted at a position where the elastic member does not protrude.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing one embodiment of the liquid crystal display device of the present invention, FIG. 2 is a front view showing one embodiment of the liquid crystal display module of the present invention, and FIG. 3 is a bottom view of the liquid crystal display module.

As shown in FIG. 1, the liquid crystal display device 1 accommodates and fixes the liquid crystal display module 2 in the housing 4 so that the display surface 3 on the front surface of the liquid crystal display module 2 can be viewed from the display window 5 of the housing 4 to the outside. It consists of.

The liquid crystal display module 2 has a liquid crystal display panel 6 and its driving circuits 7, 8 arranged and fixed on a frame 9 as shown by a broken line in FIG. A backlight 1 in which a liquid crystal display module 2 illuminates a liquid crystal display panel 6
In the case of a structure including 0, the backlight 10 can be arranged and fixed to the frame 9. The backlight 10 can be used as a planar light source by combining with a light guide plate (not shown) arranged on the back of the liquid crystal display panel 6.

On the rear side of the liquid crystal display module 2, a plurality of elastic members 11 for pressing the liquid crystal display module 2 against the front side of the housing 4 are integrally mounted. As shown in FIGS. 2 and 3, the elastic members 11 are arranged at the four corners on the back surface of the display module 2 so as not to protrude from the upper, lower, left and right sides of the display module 2. The elastic member 11 can be configured to have an elastic force capable of holding the liquid crystal display module 2 disposed in the housing 4 in a state of being pressed against the front surface of the housing 4, and a coil-type spring as shown in the drawing. In addition, a leaf spring or other springs can be used.

The housing 4 can be constructed by combining upper and lower cases 12 and 13 for accommodating the liquid crystal display module 2. In this example, after the liquid crystal display module 2 is accommodated in the lower case 13, the upper case 12 is moved to the lower case 13. By fitting or screwing to the lower case 13, the two cases 12, 13
Is being assembled. The housing 4 has a structure for restricting the movement of the accommodated liquid crystal display module 2 in the vertical and horizontal directions. This restricting structure includes, for example, a plurality of guide ribs 1 formed integrally with the lower case 13.
4 and 14.

Liquid crystal display module 2 housed in housing 4
Is fixedly mounted on the housing 4 by restricting movement in the up-down and left-right directions by the restricting structure formed on the housing 4 and restricting movement in the front-rear direction by the elastic member 11. The liquid crystal module 2 pushed to the front side of the housing 4 is connected to the housing 4 via the display window 5 or when the display device 1 is used.
A predetermined force is applied to the liquid crystal module 2 from the external force because the elastic member 11 exists between the housing 4 and the elastic member 11 to absorb a part of the force. In order to protect the portion of the liquid crystal display module 2 that is pressed by the elastic member 11 and abuts on the housing 4, one of the liquid crystal display module 2 and the housing 4 in the abutting region is provided with a buffer such as a rubber cushion. A member may be arranged.

As described above, in the liquid crystal display device 1, the liquid crystal display module 2 is positioned and arranged on the lower case 13 of the housing 4, and the liquid crystal module 2 is pressed while resisting the elastic force of the elastic member 11. Since the upper case 12 can be fitted or screwed to the lower case 13 and assembled, the operation for fixing the liquid crystal display module 2 can be simplified by also being used for assembling the cases 12 and 13. Workability can be improved.

The elastic member 11, which is a means for fixing the liquid crystal display module 2 to the housing, is disposed on the rear surface of the liquid crystal display module 2 so as not to protrude from the upper, lower, left and right sides of the liquid crystal display module 2. , Liquid crystal display device 1
A large effective display area can be ensured by setting a peripheral area called a picture frame narrow.

[0015]

As described above, according to the present invention, it is possible to provide a liquid crystal display device capable of securing a wide effective display area and a liquid crystal display module suitable for the liquid crystal display device. Further, the workability of assembling the liquid crystal display device can be improved.
