Abstract

The invention relates to the field of display technology, in particular to a back plate of an optical fiber type backlight module. A slot body is disposed on the back plane, an LED fixing portion is disposed on the end surface of the slot body, the LED fixing portion is L-shaped, a pair of LED fixing portions are disposed on each side of the back plate at the inner side, and an LED light bar is disposed in the LED fixing portion. According to the back plate of the optical fiber type backlight module and a processing technology thereof, the back plate has better corrosion resistance and longerservice life through the pretreatment process.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backplane of an optical fiber backlight module. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device, which is composed of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. In the existing optical fiber backlight module, since the LED light bar is arranged on one side, the light on the side of the light guide plate away from the LED light bar is relatively dark, which affects the light uniformity of the entire backlight module. Contents of the invention [0003] The purpose of the present inv...
