Abstract

The invention provides a light guide plate, a backlight module, a preparation method of the backlight module and a display panel, belongs to the technical field of display, and can at least partially solve the problem of breakage of a light guide plate caused by interference between a mounting hole of the light guide plate and the side wall of a back plate of an existing backlight module. The light guide plate is characterized in that the light guide plate is provided with a light-emitting surface, a non-light-emitting surface and a first mounting through hole, the light-emitting surface and the non-light-emitting surface are oppositely arranged, the first mounting through hole penetrates through the light-emitting surface and the non-light-emitting surface, and the light guide plate comprises a first part and a second part connected with the first part, the first part surrounds the first mounting through hole, the second part is located on the side, away from the first mounting through hole, of the first part, the thickness of the first part is larger than that of the second part in the first direction, and the first direction is perpendicular to the light emitting face.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a light guide plate, a backlight module, a preparation method thereof, and a display panel. Background technique [0002] With the continuous development of display technology, users' requirements on display devices are constantly increasing. In order to further improve user experience, more and more people pay attention to full-screen display devices. [0003] A display module of a display device in the disclosed technology includes at least a backplane and a light guide plate, and the backplane is used for installing the light guide plate. Both the backplane and the light guide plate have installation holes for installing the camera, so as to realize a full-screen display of the display device. [0004] However, during the reliability test of the backlight module, due to the interference phenomenon between the installation hole of the light guide plate and the si...
