Definitions
- the present invention relates to the field of liquid crystal display, and in particular to a novel light guide plate of a backlight module and a method of fabricating the same. Background technique

There are many vertical and horizontal small wires between the two glass substrates, and the liquid crystal molecules are controlled to change direction by energization or not, and the light of the backlight module is refracted. Come out to produce the picture. Since the liquid crystal panel itself does not emit light, the light source provided by the backlight module needs to be used to display the image normally. Therefore, the backlight module becomes one of the key components of the liquid crystal display device.
- the backlight module is divided into a side-in backlight module and a direct-lit backlight module according to different incident positions of the light source.
