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...
