Abstract
The present disclosure relates to the field of display technologies, and especially discloses a backlight device and a method for manufacturing the same. The backlight device includes a backlight source, a light guide plate, a reflective layer, an optical adhesive layer and an outcoupling structure. Specifically, in the backlight device, the reflective layer and the light guide plate are located on opposite sides of the backlight source respectively.
Claims15
A backlight device, comprising:
- a backlight source;
- a light guide plate on a light exit side of the backlight source;
- a reflective layer on a side of the backlight source opposite the light guide plate;
- an optical adhesive layer on one of a first surface of the light guide plate facing towards the backlight source or a second surface of the light guide plate facing away from the backlight source;
- and
- an outcoupling structure on an other one of the first surface of the light guide plate facing towards the backlight source or the second surface of the light guide plate facing away from the backlight source,
- wherein the optical adhesive layer comprises a plurality of grooves in a first array and a light emitting quantum dot material within ones of the plurality of grooves,
- wherein the light emitting quantum dot material is configured to receive light from the backlight source and at least partially convert the light into a different wavelength light,
- wherein the outcoupling structure comprises a plurality of sub-outcoupling structures in a second array, and
- wherein the outcoupling structure is configured to couple out the light from the light guide plate.
A method for manufacturing a backlight device, comprising:
- providing a backlight source;
- providing a light guide plate on a light exit side of the backlight source;
- forming a reflective layer on a side of the backlight source opposite the light guide plate;
- forming an optical adhesive layer on one of a first surface of the light guide plate facing towards the backlight source or a second surface of the light guide plate facing away from the backlight source, wherein the optical adhesive layer comprises a plurality of grooves in a first array, wherein a light emitting quantum dot material is provided within ones of the plurality of grooves, and wherein the light emitting quantum dot material is configured to receive light from the backlight source and at least partially convert the light into a different wavelength light;
- and
- forming an outcoupling structure on the first surface or the second surface of the light guide plate that is opposite the optical adhesive layer,
- wherein the outcoupling structure comprises a plurality of sub-outcoupling structures in a second array, and
- wherein the outcoupling structure is configured to couple out the light from the light guide plate.
