Abstract

The invention discloses a lateral light-entering type LED liquid crystal backlight module, which comprises an outer frame, a middle frame, liquid crystal glass, a back plate, a reflective sheet, a light guide plate, an optical diaphragm, a radiating plate and an LED light bar. The back plate comprises a bearing surface and a radiating surface, the reflective sheet, the light guide plate and the optical diaphragm are sequentially stacked on the bearing surface of the back plate from bottom to top, the radiating plate is fixed to the radiating surface of the back plate, the radiating plate is close to the edge of the light entering side of the light guide plate, a light bar fixing portion is arranged on the light guide plate in a projecting manner, and the LED light bar is fixed to the light bar fixing portion. The radiating plate can be rapidly detached from the back plate, the LED light bar is replaced by a non-defective light bar, rework process is greatly simplified, rework time is shortened, the probability of leading other materials to be defective during rework can be greatly reduced, and radiating effects are greatly improved owing to the designed structure.

Description

technical field [0001] The invention belongs to the technical field of televisions, and in particular relates to a side-light type LED liquid crystal backlight module. Background technique [0002] With the development of science and technology, LED has also begun to be used in TV imaging technology due to its ultra-thin, environmental protection and energy-saving characteristics. [0003] Such as figure 1 As shown, it is a cross-sectional structure of a side-illuminated LED liquid crystal backlight module. The side-illuminated LED liquid crystal backlight module includes: an outer frame, a middle frame, a back plate, and heat dissipation elements stacked on the back plate in sequence from bottom to top. Aluminum strips, reflectors, light guide plates, optical membranes, and liquid crystal glass are provided with LED light bars near the light-incident side of the light guide plate. [0004] If the LED breaks down, a new LED light bar must be replaced. At present, it is ver...
