Problems solved by technology

In addition, the backplane 100 must retain a large piece of material to provide anti-light leakage and heat dissipation functions, but this is also the main reason why the liquid crystal display cannot be effectively reduced in weight

Abstract

The invention relates to a reflecting backboard which is suitable for a backlight module with a light source group. The reflecting backboard comprises a frame and a reflecting piece, wherein the frame is provided with at least one hollow opening; the reflecting piece is assembled in the frame; the reflecting piece is provided with a reflecting layer and a radiating layer which are made of different materials; the reflecting layer is provided with a reflecting face and a back face opposite to the reflecting face; the reflecting face defines a concave part which is used for containing the light source group; and the radiating layer is arranged on the back face of the reflecting layer.

Description

technical field [0001] The invention relates to a reflective backplane, and in particular to a reflective backplane suitable for a direct-type backlight module of a liquid crystal display. Background technique [0002] In recent years, due to the characteristics of lightness, thinness, smallness and low power consumption, liquid crystal displays have been widely used in electronic imaging products such as notebook computers, digital cameras, and televisions, and have gradually replaced traditional cathode ray tubes (CRT, Cathode ray tube) display. [0003] A liquid crystal display mainly includes two parts: a liquid crystal panel and a backlight module. The liquid crystal panel mainly uses the rotation of the liquid crystal molecules and the polarizer to change the amount of light passing through different areas, causing differences in brightness and darkness in different areas, so as to achieve the purpose of image display. Since the liquid crystal itself does not have lu...
