Abstract

The invention discloses an LED liquid crystal display backlight module which can provide the possibility of higher brightness under the condition of not increasing spotlighting sheets, and the structure of the LED liquid crystal display backlight module can be suitable for high-power LED lamps to reduce the application of low-power LED lamps so as to reduce the probability of faults. The LED liquid crystal display backlight module comprises an LED lamp strip and a light guide plate, wherein the LED lamp strip is provided with an LED lamp; the back surface of the light guide plate is provided with the LED lamp strip; the light guide plate corresponding to the position of the LED lamp is provided with a hole; the hole comprises two orifices positioned on the front surface and the back surface of the light guide plate; the orifice positioned on the back surface of the light guide plate is provided with a direct type LED lamp; and the orifice positioned on the front surface of the light guide plate is provided with a light-reflecting device used for reflecting the light of the LED lamp. The invention is mainly used for LED backlight sources of a liquid crystal display and a liquid crystal television.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a backlight module of an LED backlight liquid crystal display. LED backlights used in LCD monitors and LCD TVs. Background technique [0002] With the development of science and technology, liquid crystal display has become common in people's daily life. Liquid crystal display and LCD TV are the most common liquid crystal display devices. Generally speaking, a complete liquid crystal display product usually includes Group (that is, LCM), circuit board (including main board and power board, etc.), back shell, support base and so on. Among them, the LCM is responsible for converting electrical signals into clear images that users see, and the circuit board is responsible for signal conversion and providing suitable power for the display. Finally, these functional components are fixedly installed in the shell composed of the front shell and the rear shell, and then fixed on the base. , ...
