Abstract

The invention discloses a back light module which comprises a light source, a light guide plate and a reflecting plate, wherein the light source is used for emitting light; the light guide plate is used for guiding the light emitted from the light source to enable the light to irradiate a display screen; the reflecting plate is used for reflecting the light emitted from the light source and the light reflected by the light guide plate to the display screen, wherein a graphite flake heat dissipation structure is arranged on the reflecting plate. According to the back light module and the liquid crystal display device, provided by the invention, heat transmitted to the reflecting plate from the light source is effectively transferred out through the graphite flake heat dissipation structure, so that the liquid crystal display device can effectively dissipate heat without causing any damage to the aesthetic feeling of the thin appearance.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a backlight module and a liquid crystal display device. Background technique [0002] At present, liquid crystal displays have become more and more popular, and people are very fond of the clarity and ultrathin appearance of liquid crystal displays. However, as the thin film transistor display becomes thinner and thinner, its heat dissipation problem is becoming more and more prominent, especially the heat generated by the light source in the backlight area is very high, and the heat is very concentrated, but because the liquid crystal display device is too thin, it cannot To achieve effective heat dissipation, there is a serious contradiction between the thin appearance of the liquid crystal display device and its heat dissipation. Contents of the invention [0003] The object of the present invention is to provide a backlight module and a liquid crystal display device ...
