Zusammenfassung:The utility model discloses a light guide plate of a controllable multi-light-source backlight module. The light guide plate is divided into more than one light-emitting area. An LED light source is arranged in each light-emitting area, a plurality of net points are distributed in the same light-emitting area at intervals from inside to outside with the LED light source as the center, the diameters of the net points are decreased along with the increase of the distance between the net points and the LED light source, and the distance between the net points is decreased along with the increaseof the distance between the net points and the LED light source. Aiming at the characteristic that the farther the light source of the LED light source is, the lower the light energy is attenuated, according to the position of the LED light source, adaptive improvement is carried out on lattice points, and the problems of local dark blocks, uneven brightness and the like of the backlight module are effectively solved. 本实用
