Light guide plate assembly, backlight module and display device

Abstract

The invention provides a light guide plate assembly comprising at least a light emitting plate group, at least an initial light guide plate and at least an intermediate light guide plate. The light guide plate assembly is characterized in that each light emitting plate group corresponds to an initial light guide plate and an intermediate light guide plate mentioned above; the light emitting plategroup comprises two light emitting plates which are disposed side by side in a predetermined direction; the initial light guide plate and one of the light emitting plate are laminated in the thicknessdirection of the light guide plate assembly; one side of the initial light guide plate is formed as a light entrance surface of the initial light guide plate, and the light entrance surface of the initial light guide plate faces the same direction as a light entrance surface of the light emitting plate laminated with the initial light guide plate; one side of the intermediate light guide plate fits a light emitting surface of the initial light guide surface while the other side of the intermediate light guide plate fits a light entrance surface of the other light emitting plate. A backlight module and a display device are also provided. The backlight module can achieve local control and is with a small thickness.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a light guide plate assembly, a backlight module including the light guide plate assembly, and a display device including the backlight module. Background technique [0002] A liquid crystal display device generally includes a liquid crystal panel and a backlight module. Traditional backlight modules include two implementations, one is direct type and the other is side type. In order to realize thinner and lighter display devices, side-type backlight modules are often used, that is, light-emitting elements are arranged on the side of the light guide plate. However, such a side-type backlight module cannot control the brightness of the light emitted by the backlight module by partition, and cannot achieve a better display effect. [0003] Therefore, how to realize the partition control of the side-type backlight module has become a technical problem to be solved urgentl...
