Description

Flat Panel Display Module {FLAT PANEL DISPLAY MODULE}

The present invention relates to a flat panel display module, and more particularly, to a flat panel display module with an improved screw fastening structure.

Recently, information processing devices have been rapidly developed to have various forms, various functions, and faster information processing speed. Information having an electrical signal form processed by such an information processing device requires a display device serving as an interface.

Recently, various flat panel display devices have been developed in comparison with CRT display devices, which are lightweight, compact, and have a function such as full-color and high resolution.

Generally, a liquid crystal display device, which is a leader of a flat panel display device, applies a voltage to a specific molecular array of a liquid crystal and converts it into another molecular array. A display device that displays an image by converting changes in optical properties such as chromaticity and light scattering characteristics into visual changes.

In general, a top mounting method and a side mounting method are used as a fastening method of a case accommodating a liquid crystal display module and a liquid crystal display module.

However, the current mounting method is used in combination with the top mounting method and the side mounting method, and both models are increasing according to the user's product specification.

1 is an exploded perspective view of a conventional liquid crystal display module, in particular, an exploded perspective view of a liquid crystal display module to which a top mounting method or a side mounting method may be applied, and FIG. 2 is a partially enlarged view of the liquid crystal display module of FIG. .

1 and 2, a conventional liquid crystal display module 100 includes a light generating unit (not shown) for providing light, a liquid crystal display panel 110 for displaying an image by receiving light from the light generating unit, and In addition, the mold frame 120 accommodating the liquid crystal display panel 110 and the effective display area of the liquid crystal display panel 110 may be defined, and the liquid crystal display panel 110 may be fixed by being coupled to the mold frame 120. It consists of a top chassis 130.

The mold frame 120 sequentially receives the backlight assembly that supplies light to the liquid crystal display panel 110 and the liquid crystal display panel 110 that receives light from the backlight assembly and displays an image.

One sidewall of the mold frame 120 such that the liquid crystal display module 100 is fastened to a front and rear case which accommodates the liquid crystal display module 100 and a top mounting method or a side mounting method. The first coupling hole 121 is formed in the second coupling hole 123 is formed in the first insertion groove 122 formed on the side wall of the mold frame 122. The other sidewall perpendicular to the sidewall on which the first and second coupling holes 121 and 123 are formed is provided with a fixing protrusion 124 protruding to the outside of the sidewall.

On the other hand, the top chassis 130 coupled to face the mold frame 120 has a third coupling hole 131 formed on one sidewall of the top chassis 130 to correspond to the first coupling hole 121. The fourth coupling hole 133 is formed in the second insertion groove 132 of the top chassis 130 corresponding to the first insertion groove 122. In addition, the sidewalls perpendicular to the sidewalls of the top chassis 130 in which the third and fourth coupling holes 131 and 133 are formed correspond to the fixing protrusions 124 of the mold frame 120 to hook the mold frame 120. The fixing hole 134 is formed in the position.

The liquid crystal display module 100 is accommodated in the front and rear cases, not shown, and the first to fourth coupling holes 121, 123, 131, and 133 formed on the sidewalls of the mold frame 120 and the top chassis 130 are formed. Engage with screws through the front or rear case. As a result, the mold frame 120 and the top chassis 130 of the liquid crystal display module 100 are firmly coupled to each other by screws, and the liquid crystal display module 100 is coupled to the front case or the rear case to complete the liquid crystal display device. do.

As described above, in the fastening structure of the liquid crystal display module and the case, as described above, the mold frame 120 and the top chassis 130 may be provided with the first and the first structures to support the side mounting method of the liquid crystal display module and the case. 3 coupling holes 121 and 131 should be formed, and second and fourth coupling holes may be formed in the mold frame 120 and the top chassis 130 to support the top mounting method between the liquid crystal display module 100 and the case. 123 and 133 should be formed.

The manufacturer of the liquid crystal display module may use the top mounting method or the side mounting method according to the demand of the consumer. Therefore, rather than dualizing the top mounting method and the side mounting method, the liquid crystal display module is manufactured by unifying the consumer to satisfy all of the mounting methods. That is, coupling holes are formed in the liquid crystal display module to support both the top mounting method and the side mounting method.

Therefore, in order to apply both the top mounting method and the side mounting method, not only the shape of the mold frame becomes complicated as described above, but also an insert must be used in each coupling hole to support two mounting methods. There is a problem that causes a cost increase.

Accordingly, the technical problem of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a mold frame having an insert capable of supporting both a top mounting method and a side mounting method, thereby simplifying the shape of the mold frame. In addition, the present invention provides a flat panel display module that can prevent a cost increase of a product.

A light generating unit (not shown), an image display means (not shown) for receiving a light from the light generating unit to display a predetermined image, and four side walls are provided to store the image display means therein, and an insertion hole ( 410 is formed and formed on the upper side of the mold frame 400 consisting of a mold frame 400 into which the insert 300 is inserted, four side walls, and an upper wall extending inwardly from the upper edge of the side walls, respectively. A top chassis 500 is shown which secures the image display means by engaging oppositely to the frame 400.

In detail, the insert 300 is the same as that shown in FIG. 3A and FIG. 3B, and overlapping portions will be omitted. When the insert 300 is inserted into the insertion hole 410 of the mold frame 400, the first coupling hole 310 of the insert 300 faces the height direction of the sidewall of the mold frame 400, and the second The coupling hole 320 faces the direction perpendicular to the side wall of the mold frame 400.

In other words, the forming direction of the first coupling hole 310 coincides with the height direction of the sidewall of the mold frame 400, and the forming direction of the second coupling hole 320 coincides with the vertical direction of the mold frame 400 sidewall. The insert 300 is inserted into the insertion hole 410 of the mold frame 400 in the direction D1.

Insertion hole 410 of the mold frame 400 is the same as the shape of the insert 300, is formed through the side wall of the mold frame 400.

The third coupling hole 420 is formed at a position corresponding to the first coupling hole 310 of the insert 300 on the sidewall of the mold frame 400 in which the insertion hole 410 is formed.

Since the liquid crystal display module 600 is fixed / received in a front or rear case not shown by screws, the insert 300 is inserted into the insertion hole 410 of the mold frame 400 to support the fastening force with the screws. Therefore, the insertion hole 410 into which the insert 300 is inserted may not pass through the sidewall of the mold frame 400.
