Optical member supporter and curved display device including the same
A display device includes: a display panel curved in a direction; a lower frame in which the display panel is accommodated, the lower frame curved in the direction in which the display panel is curved; an optical member between the display panel and the lower frame, the optical member curved in the direction in which the display panel is curved; and an optical member supporter of which an upper end portion thereof is coupled to the optical member curved in the direction in which the display panel is curved and an opposing lower end portion thereof is coupled to the lower frame curved in the direction in which the display panel is curved.
1. A display device comprising:
a display panel curved in a direction;
a lower frame in which the display panel is accommodated, the lower frame curved in the direction in which the display panel is curved;
an optical member between the display panel and the lower frame, the optical member curved in the direction in which the display panel is curved; and
an optical member supporter of which an upper end portion thereof is coupled to the optical member curved in the direction in which the display panel is curved and an opposing lower end portion thereof is coupled to the lower frame curved in the direction in which the display panel is curved.
2. The display device of claim 1 , wherein the optical member defines a guide hole therein to which the optical member supporter is coupled.
3. The display device of claim 2 , wherein the optical member supporter defines a groove therein at an upper portion thereof, the groove aligned with the guide hole defined in the optical member.
4. The display device of claim 3 , further comprising a coupling member as a separate member from the optical member and the optical member supporter, the coupling member extending through the guide hole defined in the optical member and into the groove defined in the optical member supporter to couple the optical member to the optical member supporter.
5. The display device of claim 4 , wherein the coupling member is one of a screw, a bolt, a rivet and a hook.
6. The display device of claim 4 , wherein in a plan view, a dimension of a portion of the coupling member is greater than a dimension of the guide hole defined in the optical member.
7. The display device of claim 4 , wherein
the optical member further defines a step difference portion at the guide hole to surround the guide hole defined therein, and
a portion of the coupling member is disposed in the step difference portion defined in the optical member.
8. The display device of claim 7 , wherein in a cross-section, the step difference portion has a tapered shape.
9. The display device of claim 7 , wherein in both a plan view and a cross-section, the step difference portion defined in the optical member has shapes the same as those of at least a portion of the coupling member.
10. The display device of claim 7 , wherein an uppermost surface of the coupling member is disposed at or below an uppermost surface of the optical member.
11. The display device of claim 4 , wherein the coupling member comprises a same material as that of the optical member.
12. The display device of claim 4 , wherein the coupling member comprises at least one of polycarbonate, a transparent acrylic resin, polystyrene, polymethylmethacrylate and polyethyleneterephthalate.
13. The display device of claim 2 , wherein the optical member supporter defines a protrusion protruding from an upper portion thereof toward the optical member, the protrusion aligned with the guide hole defined in the optical member.
14. The display device of claim 13 , wherein the protrusion defined by the optical member supporter is one of a screw, a bolt, a rivet and a hook.
15. The display device of claim 13 , further comprising a coupling member as a separate member from the optical member and the optical member supporter, the coupling member extending through the guide hole and coupled to the protrusion defined by the optical member supporter to couple the optical member to the optical member supporter.
16. The display device of claim 15 , wherein
the optical member further defines a step difference portion at the guide hole to surround the guide hole defined therein, and
a portion of the coupling member is disposed in the step difference portion defined in the optical member.
17. The display device of claim 13 , further comprising a coupling member as a separate member from the optical member and the optical member supporter,
wherein
the optical member further defines a step difference portion at the guide hole to surround the guide hole defined therein,
the protrusion defined by the optical member supporter extends through the guide hole, and
the coupling member is disposed outside the guide hole and in the step difference portion at the guide hole, the coupling member being coupled to the protrusion extended through the guide hole to couple the optical member to the optical member supporter.
18. The display device of claim 15 , wherein in a plan view, a dimension of a portion of the coupling member is greater than a dimension of the guide hole defined in the optical member.
19. The display device of claim 2 , wherein
the optical member supporter defines a hook protruding from an upper portion thereof toward the optical member, and
the hook defined by the optical member supporter extends through the guide hole defined in the optical member to couple the optical member supporter to the optical member.
20. The display device of claim 1 , wherein the optical member comprises at least one of a diffusion plate, a diffusion sheet, a prism sheet and a protection sheet.
