Description

Frame of the LCD module

technical field

The present invention relates to a frame (bezel) of a liquid crystal display module, more specifically, to a combined frame with high flatness.

Background technique

Liquid crystal displays are widely used in information products such as mobile phones, notebook computers, personal digital assistants, and thin flat-screen TVs due to their thin and light appearance, low power consumption, and low radiation pollution, and have gradually replaced traditional cathode ray displays. Tube (CRT) monitors have become the mainstream monitors in the market.

Generally speaking, a liquid crystal display module (LCD module) includes main components such as a liquid crystal display panel and a backlight module, and uses a plurality of frames (bezel) to fix the components such as the liquid crystal display panel and the backlight module to form a complete liquid crystal display module. Please refer to FIG. 1 , which is an exploded view of a liquid crystal display module 10 in the prior art. As shown in Figure 1, the liquid crystal display module 10 comprises a liquid crystal display panel 12, a backlight module 14, a front frame (front bezel) 16, a middle frame (middle bezel) 18 and a back frame (back bezel) 20, wherein The backlight module 14 is composed of a plurality of CCFL tubes 22 , a diffusion plate 24 and at least one brightness enhancement film 26 . The liquid crystal display panel 12 is arranged between the front frame 16 and the middle frame 18, and the backlight module 14 is arranged between the middle frame 18 and the back frame 20, and the above-mentioned liquid crystal display panel 12, the backlight module 14, the front frame 16, the middle frame Both the 18 and the back frame 20 are designed with tenons, positioning holes and assembly holes, so as to effectively fix the liquid crystal display panel 12 and the backlight module 14 to form a structurally complete liquid crystal display module 10 . In addition, as shown in FIG. 1 , the front frame 16 and the middle frame 18 are a hollow frame structure, thereby allowing the light emitted by the backlight module 14 to pass through to provide sufficient light source for the liquid crystal display panel 12, so that the user can observe the bright and beautiful display screen, and the back frame 20 has a complete rectangular planar structure because it must provide the effect of reflecting the light emitted by the backlight module 14 .

Please refer to FIG. 2 (and refer to FIG. 1 together), which is a schematic diagram of the front frame 16 of the liquid crystal display module 10 in the prior art. As shown in FIG. 2 , the front frame 16 has a hollow rectangular frame structure, so as to fix the liquid crystal display panel 12 without blocking the display screen of the liquid crystal display panel 12 . Among them, in order to provide sufficient structural strength of the liquid crystal display module 10, the front frame 16 is generally made of aluminum alloy, stainless steel or galvanized steel, etc., and the hollow part is formed by cutting or punching, and then the sheet metal stamping technology is used. Integral molding forms a hollow rectangular frame structure as shown in FIG. 2 . However, since the front frame 16 is manufactured by sheet metal stamping technology, the difference in material density at the turning point 16A of the side wall is too large, which easily leads to poor flatness of the front frame 16 . For small liquid crystal display modules, the flatness problem of the front frame 16 is not very obvious, but with the increasing size of the liquid crystal display panel 12 (especially when the size of the liquid crystal display panel 12 exceeds 20), the front frame 16 The problem of poor flatness cannot be ignored. It will not only affect the uniformity of the light source of the backlight module 14 and the display effect of the liquid crystal display panel 10, but also cause difficulty in assembling the liquid crystal display module 10. In addition, once the size of the liquid crystal display module 10 changes, the mold for sheet metal stamping must also be redeveloped and designed. For the highly competitive liquid crystal display module manufacturers, the development cost of the mold is also an important consideration in terms of cost. factor.

Contents of the invention

Therefore, the main purpose of the present invention is to provide a combined frame to solve the problem of poor flatness of the frame in the prior art.

According to a preferred embodiment of the present invention, a frame of a liquid crystal display module is disclosed, which includes a plurality of combined components, and each combined component has a structure of overlapping and fitting with each other, so that the frame can be assembled by combining.
