Framework, backlight module and liquid crystal display module

Abstract

The invention provides a framework, which is formed by bending cut plates. The maximum thickness of the framework is T, the thickness of the plates is t, and T is more than or equal to 1.5t and less than or equal to 2.5t. The framework comprises a first plate, a second plate and a bent part. The second plate is directly contacted with the first plate, and the first plate is substantially parallel to the second plate. The bent part is connected between the first plate and the second plate. The invention also provides a backlight module using the framework and a liquid crystal display module using the backlight module.

Description

【Technical field】 [0001] The invention relates to a frame, a backlight module and a liquid crystal display module, and in particular to a frame, a backlight module and a liquid crystal display module which are easy to process and have low processing cost. 【Background technique】 [0002] With the increasing maturity of optoelectronic technology and semiconductor manufacturing technology, flat panel display devices are developing vigorously. Among them, the liquid crystal display module has gradually replaced the traditional cathode ray tube display due to its advantages of low voltage operation, no radiation scattering, light weight and small size, and has become the mainstream of display products in recent years. [0003] Generally speaking, a liquid crystal display module includes components such as a backlight module and a liquid crystal display panel, wherein the liquid crystal display panel is disposed on the backlight module, and the backlight module includes a light gu...

Problems solved by technology

[0005] exist Figure 1A In the backlight module 100a, since the reflective frame 110a is used to accommodate the light-incident side of the LED light bar 120a, the reflector 160 and the light guide plate 130a, and is also used to carry the buffer pad 140 and the liquid crystal panel 150, it usually requires a larger In this way, the overall thickness of the backlight module 100a is not easy to reduce, and it is difficult to achieve the goal of thinning

[0006] In addition, in Figure 1B Although the edge-lit backlight module 100b uses an extruded aluminum heat dissipation frame 110b (heat sink) to carry the cushion pad 140 and the liquid crystal panel 150, it can simultaneously improve the structural strength, heat dissipation effect and meet the requirements of thinning, but if Making some assembly and positioning features (such as positioning notches, through holes, etc.), will increase additional post-processing costs
