Abstract
The invention discloses a light guide plate, a manufacturing method thereof, a backlight module and a display device. The light guide plate comprises a main body, a transparent material layer is arranged on a surface of the main body, and a scattering structure is arranged in the transparent material layer. The scattering structure can change the outgoing direction of first light entering the scattering structure, so that the first light has different outgoing directions, and thus a display panel can achieve normal display even in a dark environment.
Claims20
A light guide plate, comprising a main body with a plate shape, wherein a transparent material layer with a plate shape is laminated on a surface of the main body, and a plurality of scattering structures are arranged in the transparent material layer, and are configured to change outgoing direction of first light entering the plurality of scattering structures, so that the first light has different outgoing directions, wherein a plurality of absorbing structures are arranged on a side of the plurality of scattering structures away from the main body and are configured to absorb second light entering the plurality of absorbing structures, wherein both the plurality of scattering structures and the plurality of absorbing structures are distributed as mesh spots spaced apart from each other.
A manufacturing method of a light guide plate, comprising:
- laminating a transparent material layer with a plate shape on a main body of the light guide plate, wherein the main body has a plate shape;
- forming a plurality of scattering structures distributed as mesh spots spaced apart from each other in the transparent material layer, wherein the plurality of scattering structures are configured to change outgoing direction of first light entering the plurality of scattering structures, so that the first light has different outgoing directions;
- and
- forming a plurality of absorbing structures distributed as mesh spots spaced apart from each other on a side of the plurality of scattering structures away from the main body, wherein the plurality of absorbing structures are configured to absorb second light entering the plurality of absorbing structures.
