Abstract

A display device includes first light emitting devices arranged in a line in a protective member, second light emitting devices parallel to and alternately arranged with the first light emitting devices, and optical member supporters in the protective member between the first and second light emitting devices. Each optical member supporter is positioned at a center of a parallelogram defined by two adjacent first light emitting devices and two adjacent second light emitting devices, and each transparent optical member supporter includes a first surface that faces one of the first light emitting devices and a second surface opposite the first surface that faces one of the second light emitting devices. Each optical member supporter includes a plate portion having the first and second surfaces, and a hook portion that extends through the protective member. A width of the plate portion decreases with increasing distance from the hook portion.

First claim

What is claimed is:

1. A display device comprising:
an optical member;
a first light emitting unit disposed under the optical member and that includes a plurality of first light emitting devices arranged in a single line and in a first direction;
a second light emitting unit disposed under the optical member and that includes a plurality of second light emitting devices arranged in a single line and in the first direction, the plurality of second light emitting devices are alternately disposed with respect to the first light emitting devices;
a protective member that accommodates the first light emitting unit and the second light emitting units; and
a plurality of transparent optical member supporters arranged in a line extending in the first direction between the first light emitting unit and the second light emitting unit, wherein each transparent optical member supporter is positioned at a center of a smallest quadrangle defined by two adjacent first light emitting devices of the first light emitting unit and two adjacent second light emitting devices of the second light emitting unit, each transparent optical member supporter comprising:
a hook portion fixed to the protective member; and
a plate portion extended from the hook portion and including a flat first surface facing one of the first light emitting devices of the first light emitting unit, a flat second surface facing one of the second light emitting devices of the second light emitting unit located at a diagonal position with respect to the one of the first light emitting devices, and connection surfaces connecting the flat first surface and the flat second surface,
wherein the flat first surface and the flat second surface are aligned parallel with an axis of a long diagonal axis of the smallest quadrangle or a short diagonal axis of the smallest quadrangle in a top view.

2. The display device of claim 1 , wherein a width of each of the flat first and second surfaces decreases with increasing distance from the hook portion.

3. The display device of claim 1 , wherein the smallest quadrangle is a parallelogram.

4. The display device of claim 3 , wherein the parallelogram is a rhombus.

5. The display device of claim 1 , wherein the plate portion comprises at least one opening formed through the flat first surface and the flat second surface.

6. The display device of claim 5 , wherein the at least one opening is disposed symmetrically about an imaginary line that divides the flat first surface and the flat second surface into two.

7. The display device of claim 1 , wherein the protective member comprises a first thru-hole into which the hook portion is inserted.

8. The display device of claim 1 , wherein the transparent optical member supporter further comprises a supporter portion disposed on the surface of the protective member, wherein the hook portion extends in a direction normal to a plane of the supporter portion.

9. The display device of claim 8 , wherein the supporter portion has one of a circular shape or a polygonal shape on the surface of the protective member.

10. The display device of claim 8 , wherein the hook portion and the plate portion are offset from each other with respect to the supporter portion.

11. The display device of claim 8 , wherein the hook portion is located at a center of the supporter portion.

12. A display device, comprising:
a protective member;
a first light emitting unit disposed in the protective member and that includes a plurality of first light emitting devices arranged in a single line and in a first direction;
a second light emitting unit disposed in the protective member spaced apart from the first light emitting unit and closest to the first light emitting unit and that includes a plurality of second light emitting devices arranged in a single line and in the first direction, the second light emitting devices alternately arranged with the first light emitting devices; and
a plurality of transparent optical member supporters fixed to the protective member in a line parallel to and between the first light emitting unit and the second light emitting unit,
wherein each transparent optical member supporter is positioned at a center of a smallest parallelogram defined by two adjacent first light emitting devices of the first light emitting unit and two adjacent second light emitting devices of the second light emitting unit, and
wherein each transparent optical member supporter includes a flat first surface that faces one of the first light emitting devices of the first light emitting unit, a flat second surface opposite to the flat first surface that faces one of the second light emitting devices of the second light emitting unit, and connection surfaces connecting the flat first surface and the flat second surface,
wherein the flat first surface and the flat second surface are aligned parallel with an axis of a long diagonal axis of the smallest parallelogram or a short diagonal axis of the smallest parallelogram in a top view.

13. The display device of claim 12 , wherein the smallest quadrangle is a parallelogram.

14. The display device of claim 13 , wherein the parallelogram is a rhombus.

15. The display device of claim 12 , wherein each transparent optical member supporter includes a plate portion having the flat first and second surfaces, and a hook portion that extends from the plate portion through a bottom of the protective member.

16. The display device of claim 15 , wherein a width of the plate portion decreases with increasing distance from the hook portion.

17. The display device of claim 12 , further comprising:
an optical member supported by the plurality of transparent optical member supporters, and a display panel disposed on the optical member.

18. A display device comprising:
an optical member;
a plurality of light emitting units extended in a first direction and arranged in a second direction crossing the first direction, the plurality of light emitting units includes a first light emitting unit and a second light emitting unit closest to the first light emitting unit of the plurality of light emitting units;
a protective member that accommodates the plurality of light emitting units; and
a transparent optical member supporter supporting the optical member, the transparent optical member supporter comprising:
a hook portion fixed to the protective member; and
a plate portion extended from the hook portion and including a flat first surface, a flat second surface, and connection surfaces connecting the flat first surface and the flat second surface,

wherein the first light emitting unit is disposed under the optical member and includes a plurality of first light emitting devices arranged in a line,
the second light emitting unit is disposed under the optical member and includes a plurality of second light emitting devices arranged in a line, the plurality of second light emitting devices are alternately disposed with respect to the first light emitting devices,
the transparent optical member supporter is positioned at a center of a smallest quadrangle defined by two adjacent first light emitting devices and two adjacent second light emitting devices, and
