Abstract

The invention discloses an optical assembly, a backlight module and a display device. The optical assembly comprises a light guide plate, at least one first light source and at least one second light source. At least one avoiding hole penetrating to the top is formed in the bottom of the light guide plate; the first light sources are arranged at the bottom of the light guide plate, and each first light source is opposite to one avoiding hole; the second light source is arranged on the side edge of the light guide plate, and the light-emitting surface of the second light source faces the side edge of the light guide plate. According to the technical scheme, the problems that the overall brightness of a side-in type display device is not high, and the overall picture of a direct-down type display device is not uniform can be solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an optical component, a backlight module and a display device. Background technique [0002] Currently, liquid crystal display devices are mainly classified into side-type and direct-type according to the position of the light source. The light source of the side-entry display device is arranged on the side edge, and the light emitted by the light source is guided to the optical film by using a light guide plate, so that the overall picture of the display device is uniform. It is difficult to improve the overall brightness of the direct type display device; and the light source array of the direct type display device is arranged at the bottom of the liquid crystal glass, which can improve the overall brightness of the direct type display device. Inconsistency, resulting in uneven overall picture of the direct-type display device. Contents of the invention [00...
