Abstract

The invention provides a light guide plate, a manufacturing method thereof, a backlight module set and a display device and belongs to the technical field of display. The light guide plate comprises afirst light guiding region; the first light guiding region is located at one side of a groove structure, wherein the one side of the groove structure is far away from a light incident surface. A reflection surface includes a first reflection region; the first reflection region comprises at least one protruding structure; the protruding structure is at least partially overlapped with the orthographic projection of the first light guiding region at the light guide plate. The protruding structure is arranged on the reflection surface corresponding to the first light guiding region, so that it can be ensured that light reflected by the first reflection region can go out from the first light guiding region as much as possible, and therefore, the light extraction rate of the reflected light ofthe first reflection region at the first light guiding region can be improved, and therefore, the brightness of the first light guiding region can be compensated, and the brightness of the first lightguiding region of the light guide plate of a side-lit backlight module can be improved, and the uniformity of the display brightness of a display panel can be enhanced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate, a manufacturing method of the light guide plate, a backlight module and a display device. Background technique [0002] A liquid crystal display device usually includes a backlight module and a liquid crystal display panel. When the liquid crystal display panel displays images, the backlight source in the backlight module needs to provide light to realize normal display of the display device. The backlight includes direct-type backlight and side-type backlight. The side-type backlight is arranged on the side of the light guide plate, and provides a uniform surface light source for the display panel through the special reflection of the reflective surface of the light guide plate. [0003] At the same time, with the development of display technology, heterosexual display panels have attracted more and more attention due to their larger screen-to-body ratio. A...
