Abstract

The invention relates to the technical field of display, in particular to a backboard of a backlight module. An optical film containing groove is formed in the backboard, and four optical films are sequentially arranged in the backboard in a stacked mode from top to bottom; a first positioning groove, a second positioning groove, a third positioning groove and a fourth positioning groove which aresequentially arranged are formed in the inner end face of the optical film containing groove; the first positioning groove comprises a strip-shaped extension part and a hexagonal positioning groove communicated with the strip-shaped extension part; the second positioning groove comprises a strip-shaped extension part and a rectangular positioning groove communicated with the strip-shaped extension part; the third positioning groove comprises a strip-shaped extension part and a trapezoidal positioning groove communicated with the strip-shaped extension part; the fourth positioning groove comprises a strip-shaped extension part and a circular positioning groove communicated with the strip-shaped extension part. According to the backboard of the backlight module and a manufacturing method ofthe backboard, the method is simple, and the manufactured backboard is long in service life and good in abrasion resistance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backplane of a 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. Existing liquid crystal displays usually include a backlight module and a liquid crystal panel. The backlight module is provided with an LED light and an optical film group. In the existing backlight module, the optical film group is prone to positional deviation, which affects the quality of the liquid crystal display. Effect. Contents ...
