Abstract

The invention provides a light guide plate which comprises a light guide part and a light incident part which bends and extends from the end of the light guide part and is used for guiding light emitted by a light source into the light guide part. The invention further provides a backlight module which comprises the light guide plate. The invention further provides a display device which comprisesthe backlight module. According to the light guide plate, the front face of the light incident part comprises a first convex face, a first plane and a first concave face which are sequentially bent and connected, the first convex face is used for refracting light emitted by the light source into the light incident part, the first plane is used for reflecting light emitted in through the first convex face, the first concave face is used for reflecting light emitted in through the first convex face to the light guiding part and further reflecting light reflected by the first plane to the lightguiding part, on the basis of the first convex face, the first plane and the first concave face, on the basis of website scattering, light propagation paths are effectively scattered, and therefore light can be evenly emitted out through the light emitting face.

Description

technical field [0001] The invention belongs to the field of display technology, and more specifically relates to a light guide plate, a backlight module and a display device. Background technique [0002] The backlight module mainly provides a light source for the display device, so that the naked eye can clearly see the displayed information on the screen. The current backlight module can be applied to various aspects of daily life, such as communication products, GPS lights, high-tech products, but , the structure of the light guide plate in the current backlight module is not reasonable enough, the controllability of the directionality of the light guide is low, and the uniformity is poor, so the light output of the existing backlight module is not uniform, so there is a need for improvement. Contents of the invention [0003] The object of the present invention is to provide a light guide plate to solve the technical problem of uneven light emission from the light gui...
