Abstract

A liquid crystal display has a frame including a base and a reinforced portion extending from the base, the reinforced portion defining a partial edge of the frame. The liquid crystal display further includes an optical sheet on the base, the optical sheet including a backlight unit, a flexible printed circuit on the optical sheet, and a liquid crystal display panel comprising a large scale integrated circuit, the liquid crystal display panel substantially covering the optical sheet. A window is attached to and substantially covers the frame at least one support extends from the base for supporting the window and/or the backlight unit.

Claims (37)

1. A liquid crystal display comprising:

a frame comprising a base and a reinforced portion protruding around at least a portion of the base, such that a thickness of the frame is greater at the reinforced portion than at the base alone;

an optical sheet on the base, the optical sheet including a backlight unit;

a flexible printed circuit on the optical sheet;

a liquid crystal display panel comprising a large scale integrated circuit, the liquid crystal display panel substantially covering the optical sheet;

a window attached to and substantially covering the frame; and

at least one support protruding from the base and contacting the window to provide support thereto.

2. The liquid crystal display as claimed in claim 1 , wherein the at least one support is a pillar having any one cross-sectional shape selected from a circle, a triangle, and a rectangle.

3. The liquid crystal display as claimed in claim 1 , wherein the at least one support protrudes into a space between the large scale integrated circuit and the window to protect the large scale integrated circuit from an external impact or pressure.

4. The liquid crystal display as claimed in claim 1 , wherein the at least one support protrudes into a space between the large scale integrated circuit and the window to protect the liquid crystal display panel from an external impact or pressure.

5. The liquid crystal display as claimed in claim 1 , wherein the flexible printed circuit comprises at least one through hole through which the at least one support protrudes.

6. The liquid crystal display as claimed in claim 1 , wherein a portion of a periphery of the base is absent from the reinforced portion so that the base can accommodate the flexible printed circuit.

7. The liquid crystal display as claimed in claim 6 , wherein the at least one support is a pillar having any one cross-sectional shape selected from a circle, a triangle, and a rectangle.

8. The liquid crystal display as claimed in claim 1 , wherein a height of the at least one support is about equal to a thickness of the reinforced portion.

9. The liquid crystal display as claimed in claim 1 , further comprising at least two supports arranged linearly.

10. The liquid crystal display as claimed in claim 1 , further comprising at least three supports arranged non-linearly.

11. The liquid crystal display as claimed in claim 10 , wherein the flexible printed circuit comprises one through hole for each of the at least three supports, each of the at least three supports protruding through each corresponding through hole.

12. The liquid crystal display as claimed in claim 1 , wherein the window is attached to the reinforced portion.

13. A method for manufacturing a liquid crystal display comprising:

providing a frame having at least one support protruding from the frame in a thickness direction;

placing an optical sheet within the frame;

placing a flexible printed circuit on one side of the optical sheet;

placing a liquid crystal display panel on the optical sheet, the liquid crystal display panel including a large scale integrated circuit; and

placing a window onto the frame such that the at least one support contacts the window to provide support thereto.

14. The method for manufacturing a liquid crystal display as claimed in claim 13 , wherein the at least one support is a pillar having any one cross-sectional shape selected from a circle, a triangle, and a rectangle.

15. The method for manufacturing a liquid crystal display as claimed in claim 13 , wherein the at least one support protrudes into a space between the large scale integrated circuit and the window to protect the large scale integrated circuit from an external impact or pressure.

16. The method for manufacturing a liquid crystal display as claimed in claim 13 , wherein the at least one support protrudes into a space between the large scale integrated circuit and the window to protect the liquid crystal display panel from an external impact or pressure.

17. The method for manufacturing a liquid crystal display as claimed in claim 13 , wherein the flexible printed circuit comprises at least one through hole through which the at least one support protrudes.

18. The method for manufacturing a liquid crystal display as claimed in claim 13 , wherein the frame comprises:

a base, wherein the at least one support extends from the base; and

a reinforced portion extending from the base, the reinforced portion defining a partial edge of the frame.

19. The method for manufacturing a liquid crystal display as claimed in claim 18 , wherein the at least one support is a pillar having any one cross-sectional shape selected from a circle, a triangle, and a rectangle.

20. The method for manufacturing a liquid crystal display as claimed in claim 18 , wherein a height of the support is about equal to a thickness of the reinforced portion.

21. The method for manufacturing a liquid crystal display as claimed in claim 18 , the frame further comprising at least two supports arranged linearly.

22. The method for manufacturing a liquid crystal display as claimed in claim 18 , the frame further comprising at least three supports arranged non-linearly.

23. The method for manufacturing a liquid crystal display as claimed in claim 22 , wherein the flexible printed circuit comprises one through hole for each of the at least three supports, each of the at least three supports protruding through one corresponding through hole.

24. The method for manufacturing a liquid crystal display as claimed in claim 18 , wherein the window is attached to the reinforced portion.
