LCD module and liquid crystal display device using the same

The present invention relates to an LCD module and a liquid crystal display device using the same. More particularly, the liquid crystal display can reduce the overall weight of the case by reducing the coupling space between the LCD module and the case by changing the combination of the LCD module and the case. A device and an LCD module applied to such a liquid crystal display device.

In general, as the modern society becomes information socialized, the importance of liquid crystal display devices such as notebook computers, which are one of information display devices, is gradually increasing.

Cathode ray tube (CRT), which is widely used so far, has many advantages in terms of performance and cost, but has many disadvantages in terms of miniaturization or portability.

On the other hand, as an image display module applied to a liquid crystal display device such as a notebook computer, a liquid crystal display module (hereinafter referred to as an LCD module) applying the physical and optical characteristics of the liquid crystal is widely adopted, and a conventional CRT Compared to (Cathode Ray Tube), it has the advantages of miniaturization, light weight, thinness and low power consumption, but it is more expensive, but it has the advantages of miniaturization, light weight, thinness and low power consumption. It is attracting attention as a means.

Protruding from four corners, the screw through the screwing hole of the mounting portion 2 is generally coupled to the lower case 8, the LCD module 4 is fixed to the lower case (8).

However, in the top mounting method, since mounting parts are protruded from four corners of the top chassis of the LCD module, and a screw coupling structure is applied to the mounting parts for screwing with the lower case, there are limitations in reducing the size of the mounting parts. Due to this, the size of the lower case is increased by the protruding length of the mounting portion, thereby increasing the overall weight of the case.

In addition, there is a problem that the work efficiency for the assembly of the LCD module and the case is degraded due to the inconvenience caused by the screw coupling.

Accordingly, an object of the present invention is to minimize the size of the case by changing the combination of the LCD module and the case, and to improve the work efficiency for the assembly of the LCD module and the case.

Hereinafter, a liquid crystal display and an LCD module according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2 or FIG. 3, the liquid crystal display device includes an LCD module 10 that displays data largely and a case that covers the upper and lower sides of the LCD module 10 except for the data display area. 12).

The LCD module 10 includes an LCD panel 14 for displaying data, a backlight assembly positioned at a rear surface of the LCD panel 14 to generate light, a mold frame for accommodating them, and a top edge and a mold frame of the LCD panel 14. It includes a top chassis 16 that is fixed to the mold frame while wrapping the side of the.

The case 12 includes a lower case 18 surrounding the lower portion of the LCD module 10 and an upper case 20 surrounding the upper portion of the LCD module 10 except for the data display area and coupled to the lower case 18.

According to the present invention, as shown in FIG. 3, the insertion protrusions 22 are spaced apart from each other by the outer side of the LCD module 10 on the sides of the LCD module 10, for example, opposite sides of the LCD module 10. It is formed to protrude in a pair, an insertion hole 24 is formed between the insertion protrusion 22 and the side of the LCD module 10.

The insertion protrusion 22 cuts a predetermined area of the side surface of the top chassis 16 in the width direction of the top chassis 16 in a balanced manner, and then protrudes from the inside to the outside through the press working process between the cut portions. In this case, an insertion hole 24 having a predetermined width is formed between the insertion protrusion 22 and the side surface of the top chassis 16.

Of course, the insertion protrusion 22 may be formed on the side of the top chassis 16 through an injection molding operation and various other processes in addition to the press working.
