Abstract

The invention discloses a light guide plate. The light guide plate comprises a light incidence side surface (11), a first side surface (12), a second side surface (13) and a third side surface (14), wherein the light incidence side surface (11) and the third side surface are opposite to each other, the first side surface (12) and the second side surface (13) are opposite to each other, and the first side surface (12), the second side surface (13) and the third side surface (14) are respectively provided with a reflecting structure. The invention also discloses a backlight module with the light guide plate. When light enters a side surface of the reflecting structure from the light incidence side surface, the light is reflected by the reflecting structure to the light guide plate, so that the light utilization rate can be increased, the bright zone on the side surface of the light guide plate can be avoided, and the uniformity of the emitted light of the backlight module can be improved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a light guide plate and a backlight module with the light guide plate. Background technique [0002] Liquid crystal display devices have the advantages of thinness, low power consumption, and low radiation, and are widely used in electronic display devices such as notebook computers, mobile phones, and electronic dictionaries. In recent years, with the continuous development of liquid crystal display technology, its use environment has also changed. The frequency of outdoor use is increasing, and people's demand for vision is also increasing. It is hoped that a liquid crystal display device with higher brightness can be developed. [0003] Therefore, it is necessary to improve the light utilization rate of the backlight module, and among all the components forming the backlight module, the light guide plate (LGP) plays a very important role in improving...
