Abstract
A light guide plate includes a first transparent base layer, an adhesive layer and a transparent composite layer. The adhesive layer is configured for bonding the transparent composite layer on the first transparent base layer. The transparent composite layer is located on the adhesive layer, and the transparent composite layer comprising a light emitting surface, the light emitting surface includes a plurality of microstructures.
Claims20
A light guide plate comprising:
- a first transparent base layer and a transparent composite layer having a light emitting surface comprising a plurality of microstructures;
- and
- an adhesive layer bonding the first transparent base layer to the transparent composite layer.
A method for manufacturing a light guide plate, the method comprising:
- providing a platform and a second transparent base layer, the platform comprises a heating device, arranging the second transparent base layer on the platform, the second transparent base layer comprises a first surface and a second surface away from the first surface, heating the second transparent base layer to enable the second transparent base layer to reach its molten state;
- providing a mold die, the mold die is substantially cubic and comprises an pressing surface, the pressing surface has a plurality of microstructures, the mold die is configured for molding microstructures on the first surface of the second transparent base layer to obtain the transparent composite layer;
- providing a first transparent base layer, the first transparent base layer comprising a combined surface, coating a first glue on the combined surface;
- attaching the transparent composite layer to the first transparent base layer;
- providing a pressing roller, applying the pressing roller to pressing the transparent composite layer to enable the transparent composite layer adhesive to the first transparent base layer;
- and
- solidify the first glue to form the adhesive layer, and the light guide plate is finished.
