Abstract
A light guide plate includes a transparent substrate and a plurality of micro structures. The transparent substrate has a first surface and a second surface opposite the first surface, and the micro structures are disposed at least on the first surface of the transparent substrate and are separate from each other. Each of the micro structures includes a first coating layer and a second coating layer. The first coating layer is formed on the first surface and includes an adhesive material. The second coating layer is formed on at least a part of the first coating layer and includes a light-diffusing material.
Claims23
A light guide plate, comprising:
- a transparent substrate having a first surface and a second surface opposite the first surface;
- and
- a plurality of micro structures, disposed at least on the first surface of the transparent substrate, the micro structures being separate from each other and each of the micro structures comprising:
- a first coating layer formed on the first surface and comprising an adhesive material;
- and
- a second coating layer formed on at least a part of the first coating layer and comprising a light-diffusing material.
A light guide plate, comprising:
- a transparent substrate having a first surface and a second surface opposite the first surface;
- a plurality of fifth micro structures disposed at least on the first surface of the transparent substrate, the fifth micro structures being separate from each other and each of the fifth micro structures comprising:
- a first coating layer formed on the first surface and comprising an adhesive material;
- and
- a second coating layer formed on at least a part of the first coating layer and comprising a light-diffusing material;
- and
- a plurality of sixth micro structures disposed at least on the first surface of the transparent substrate, wherein the sixth micro structures are separate from each other and each of the sixth micro structures is made of the adhesive material but does not contain the light-diffusing material.
A backlight module, comprising:
- a light guide plate, comprising:
- a transparent substrate having a bottom surface, a light-emitting surface and a light incident surface, wherein the light-emitting surface is opposite the bottom surface, and the light incident surface is connected the bottom surface and the light-emitting surface;
- and
- a plurality of micro structures disposed at least on the bottom surface of the transparent substrate, the micro structures being separate from each other and each of the micro structures comprising a first coating layer and a second coating layer, wherein the first coating layer is formed on the bottom surface and comprises an adhesive material, and the second coating layer is formed on at least a part of the first coating layer and comprises a light-diffusing material;
- and
- a light source disposed on one side of the transparent substrate, facing the light incident surface, and capable of emitting a light beam, wherein the light beam is capable of entering the transparent substrate from the light incident surface, being deflected by the micro structures, and leaving the transparent substrate via the light-emitting surface.
