Abstract
Disclosed herein is a backlight unit including a light guide plate including a light emitting portion to emit light, side surfaces defining corners, and a first light incidence portion and a second light incidence portion to receive light, at least two light emitting modules respectively disposed to face the first light incidence portion and the second light incidence portion, and an optical sheet disposed on the light guide plate, wherein the first light incidence portion is disposed one corner region of the light guide plate, and the second light incidence portion is disposed another corner region of the light guide plate, wherein the first light incidence portion is facing the second light incidence portion or disposed to both sides of one side surface of the light guide plate.
Claims18
A backlight unit comprising:
- a light guide plate including a light emitting portion to emit light, side surfaces defining corners, and a first light incidence portion and a second light incidence portion to receive light;
- at least two light emitting modules respectively disposed to face the first light incidence portion and the second light incidence portion;
- and
- an optical sheet disposed on the light guide plate,
- wherein the first light incidence portion is disposed one corner region of the light guide plate, and the second light incidence portion is disposed another corner region of the light guide plate,
- wherein the first light incidence portion is facing the second light incidence portion or disposed to both sides of one side surface of the light guide plate, and
- wherein at least one of the light emitting modules comprises:
- a circuit board;
- and
- a plurality of light emitting devices spaced from each other on the circuit board and arranged in one plane.
A backlight unit comprising:
- a light guide plate including light incidence portions having a curved surface type or a polygonal surface type formed at least one side surface of the light guide plate, wherein the light guide plate comprises first to fourth surfaces and the light incidence portion is disposed on at least one of the first to fourth surfaces;
- a light emitting module disposed to face the light incidence portion;
- and
- an optical sheet disposed on the light guide plate,
- wherein the light emitting modules comprise:
- a circuit board arranged to face an associated one of the light incidence portions, the circuit board having a curved or bent portion corresponding to the associated light incidence portion;
- and
- light emitting elements disposed on the circuit board to face the associated light incidence portion.
A backlight unit comprising:
- a light guide plate including first to fourth side surfaces and a concave light incidence portion formed at least one of the side surfaces;
- and
- a light emitting module disposed to face the light incidence portion,
- wherein the second and fourth side surfaces are disposed at both ends of the first side surface,
- wherein the light incidence portion has a shape substantially identical to a reduced scale of a virtual line drawn to extend from a corner, at which the first and second side surfaces meet, to a corner, at which the first and fourth surfaces meet, while contacting a virtual line connecting centers of the second and fourth side surfaces, and
- wherein the light emitting module comprises:
- a circuit board arranged to face the light incidence portion, the circuit board having a curved or bent portion corresponding to the light incidence portion;
- and
- light emitting elements disposed on the circuit board to face the light incidence portion.
