BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device module, and more particularly, a support main frame that borders a side of an edge of a liquid crystal panel and a back-light assembly that is stacked up and down. It is related to the coupling structure of the cover bottom (close bottom) in close contact with the main and its back.

In recent years, as the society enters the information age, the display field that processes and displays a large amount of information has been rapidly developed, and recently, the thin film transistor (Thin) having excellent performance of thinning, light weight, and low power consumption has recently been developed. Film Transistor (TFT) type liquid crystal display (TFT-LCD) has been developed to replace the existing cathode ray tube (CRT).

The image realization principle of a general liquid crystal display device uses optical anisotropy and polarization property of liquid crystal. As is well known, a liquid crystal has a thin and long molecular structure and its optical anisotropy having an orientation in an array and its size when placed in an electric field. As a result, the orientation of the molecular sequence changes. The liquid crystal display is an essential component of a liquid crystal panel composed of a pair of transparent insulating substrates, each having a liquid crystal layer interposed therebetween, and having a field generating electrode formed thereon. Through artificially adjusting the alignment direction of the liquid crystal molecules through the display of various images by using the change in the transmittance of light.

In this case, since a general liquid crystal panel does not have a light emitting element, it requires a separate light source. For this purpose, a backlight assembly is provided on the back of the liquid crystal panel to supply light.

In addition, the liquid crystal panel and the backlight assembly are modularized using various mechanical elements, thereby minimizing protection from impact and minimizing light loss. The attached FIG. 1 is an exploded perspective view of a general liquid crystal display module, and has an approximately rectangular frame shape. The backlight assembly 20 and the liquid crystal panel 30 are sequentially stacked inside the support main 10, and the support main 10 is prevented from being deformed and the protection of the fluorescent lamp 24 described later. A cover bottom 40 is coupled to the back of the main 10, and a top cover 50 that borders the front edge of the liquid crystal panel 30 is fixed to the support main 10 to fix both of them. And it is assembled and fastened to the cover bottom 40.

At this time, the liquid crystal panel driver circuit 34 is connected to at least one side of the liquid crystal panel 30 via a flexible printed circuit board 32, and is folded and adhered to the back side during the modularization process.

The backlight assembly 20 may include a white or silver reflective sheet 22 interposed on the upper surface of the support main 10, and a fluorescent lamp 24 arranged along the inner side of the edge of the support main 10 at its front surface. A light guide panel (LGP) 26 having a predetermined thickness so as to occupy the same plane and refracting the light incident on the side to the front side, and a plurality of optical sheets covering the same; 28).

Accordingly, the light emitted from the fluorescent lamp 24 is processed toward the liquid crystal panel 30 by the reflective sheet 22 and the light guide plate 26 and processed to a high quality of uniform luminance while passing through the optical sheet 28. 30), the liquid crystal panel 30 may display a high brightness image to the outside.

Meanwhile, in the above description, the support main 10 and the cover bottom 40 are generally screwed to each other.

In the case of referring together, a plurality of bolt holes 42 are perforated up and down at the edge of the cover bottom 40, and a plurality of screws 44 are respectively bolt holes 42 of the cover bottom 40 Through the main support 10 is inserted into the back to fix each other.

However, when the support main 10 and the cover bottom 40 are coupled using the plurality of screws 44 as described above, the support main 10 made of a synthetic resin or a metal material due to friction with the respective screws 44 is provided. A phenomenon in which foreign matters are frequently generated is generated, and this causes a problem in that the backlight assembly 20 or the liquid crystal panel 30 is polluted and acts as a direct cause of deterioration of image quality. In addition, the process of fastening each screw 44 by using a tool such as a screwdriver is a very cumbersome task, and shows a disadvantage of requiring unnecessary manpower and time.

Attempts have been made to stably fix the support main 10 and the cover bottom 40 without using the screw 44. As another example, another liquid crystal display module shown in FIGS. 3 and 4 has been introduced. have. FIG. 3 is an exploded perspective view of another general liquid crystal display module and FIG. 4 is a perspective view showing a part of the rear surface according to its coupling state, and the same reference numerals are given to the same parts which play the same role in order to avoid duplication of description.
