Abstract

Provided is a backlight frame, which comprises a frame body comprising attaching blocks disposed at four corner portions of the frame body, respectively, and a metal plate disposed on a mounting surface of at least one of the attaching blocks. A hardness of the metal plate is higher than a hardness of the attaching blocks. The metal plates are capable of reducing the defects of the backlight due to abrasive dust and thus facilitating the assembling process and improving the quality and yield of the products.

Claims (20)

1. A backlight frame comprising:

a frame body comprising attaching blocks disposed at four corner portions of the frame body, respectively, and each projected on a bar of the frame body to be assembled with a back plate and a light guiding plate through a mounting surface,

a metal plate disposed on the respective mounting surface of each of the attaching blocks and inside the frame body,

wherein the mounting surface of each of the attaching blocks faces the inside of the frame body and is parallel to the respective bar of the frame body, and

wherein a hardness of the metal plate is higher than a hardness of the attaching blocks.

2. The backlight frame according to claim 1 , wherein the metal plate is disposed on a longitudinal mounting surface of the at least one of the attaching blocks.

3. The backlight frame according to claim 2 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 10 mm-15 mm in length, 4 mm-6 mm in width and 0.4 mm-0.6 mm in thickness.

4. The backlight frame according to claim 3 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 12 mm in length, 6 mm in width and 0.5 mm in thickness.

5. The backlight frame according to claim 2 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 15 mm-20 mm in length, 4 mm-6 mm in width and 0.4 mm-0.6 mm in thickness.

6. The backlight frame according to claim 5 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 17 mm in length, 6 mm in width and 0.5 mm in thickness.

7. The backlight frame according to claim 1 , wherein metal plates are disposed on both a longitudinal mounting surface and a horizontal mounting surface of the at least one of the attaching blocks.

8. The backlight frame according to claim 7 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 10 mm-15 mm in length, 4 mm-6 mm in width and 0.4 mm-0.6 mm in thickness.

9. The backlight frame according to claim 8 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 12 mm in length, 6 mm in width and 0.5 mm in thickness.

10. The backlight frame according to claim 7 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 15 mm-20 mm in length, 4 mm-6 mm in width and 0.4 mm-0.6 mm in thickness.

11. The backlight frame according to claim 10 , wherein the metal plate disposed on the longitudinal mounting surface of the at least one of the attaching blocks has a dimension of 17 mm in length, 6 mm in width and 0.5 mm in thickness.

12. The backlight frame according to claim 7 , wherein the metal plate disposed on the horizontal mounting surface of the at least one of the attaching blocks has a dimension of 1 mm-2 mm in length, 4 mm-6 mm in width and 0.4 mm-0.6 mm in thickness.

13. The backlight frame according to claim 12 , wherein the metal plate disposed on the horizontal mounting surface of the at least one of the attaching blocks has a dimension of 1.5 mm in length, 6 mm in width and 0.5 mm in thickness.

14. The backlight frame according to claim 1 , wherein the metal plate is made of aluminum.

15. The backlight frame according to claim 2 , wherein the metal plate is made of aluminum.

16. The backlight frame according to claim 7 , wherein the metal plates are made of aluminum.
