Problems solved by technology

Liquid crystal display is a passive light-emitting display, which needs a backlight source to provide light source for it. The backlight source includes LED light strips. The heat generated by the strip cannot be dissipated in time, which shortens the service life of the LED strip. In addition, other components in the LCD display will also deform when heated, which affects the performance and life of the LCD display.

Abstract

The invention provides a liquid crystal display device and a backlight module thereof. The backlight module comprises a light guide plate, a reflecting layer, an optical diaphragm assembly and a light emitting assembly, wherein the optical diaphragm assembly is arranged at the top of the light guide plate, the reflecting layer is arranged at the bottom of the light guide plate, the light emitting assembly comprises an LED strip corresponding to a light incoming surface of the light guide plate and a substrate arranged at the bottom of the LED strip, and the substrate extends to the bottom of the reflecting layer. The substrate is arranged at the bottom of the reflecting layer, and the substrate extends to the bottom of the reflecting layer, so that an assembling space of the substrate is increased, the size of the substrate can be larger, the heat radiation of the LED strip can be facilitated, the service life of the LED strip and the liquid crystal display device can be prolonged, and the performance of the liquid crystal display device can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display and a backlight module thereof. Background technique [0002] Liquid crystal display has the advantages of thin body, low power consumption, no radiation, etc., and has been more and more widely used. Liquid crystal display is a passive light-emitting display, which needs a backlight source to provide light source for it. Among them, the backlight source includes LED light strips. The heat generated by the strip cannot be dissipated in time, thereby shortening the service life of the LED light strip. In addition, other components in the liquid crystal display will also be deformed when heated, thereby affecting the performance and life of the liquid crystal display. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a liquid crystal display and its backlight module, which can improve t...
