Abstract

A display device includes a display panel having a display area and a bezel area formed around edges of the display area; a backlight unit disposed on a rear side of the display panel to provide light to the display panel; a supporting member to support the display panel and the backlight unit; and a top case having at least one joint and incorporated with a surface of the supporting member, wherein the top case has a main frame combined with the supporting member and a sub frame disposed on the bezel area and combined with the main frame.

First claim

What is claimed is:

1. A display device, comprising:
a display panel having a display area and a bezel area formed around edges of the display area;
a backlight unit disposed on a rear side of the display panel to provide light to the display panel;
a supporting member to support the display panel and the backlight unit; and
a top case having at least one joint and incorporated with a surface of the supporting member,
wherein the top case has a main frame combined with the supporting member, and a sub frame disposed on the bezel area and combined with the main frame;
wherein the sub frame includes a transparent thermoplastic resin;
wherein the main frame is disposed on a side surface of the supporting member and exposes a top surface of the supporting member;
wherein the sub frame covers the top surface of the supporting member exposed by the main frame;
wherein the main frame includes a metal having a pattern on at least a surface thereof at an interface between the main frame and the sub frame;
wherein the pattern includes minute uneven designs formed by a chemical treatment process; and
wherein the main frame of the metal and the sub frame of the transparent thermoplastic resin are perpendicularly combined with each other so that the sub frame of the transparent thermoplastic resin is exposed toward a front direction of the display device.

2. The device according to claim 1 , wherein the sub frame is bonded to the main frame by an injection molded thermoplastic resin.

3. The device according to claim 1 , wherein the supporting member includes a bottom cover to accommodate the display panel and the backlight unit, and a main support to fix positions of the display panel and the backlight unit.

4. The device according to claim 1 , further comprising a pad disposed between the backlight and the display panel to absorb impact and to protect the display panel from dust.

5. The display device according to claim 1 , wherein the main frame of the top case includes a plurality of metal plates connected to each other at the at least one joint to surround the display panel and the supporting member.

6. The display device according to claim 5 , wherein the metal plates are firmly combined by the sub frame formed of a thermoplastic resin disposed on top surfaces of the metal plates.

7. The display device according to claim 5 , wherein the connected metal plates define an opening with the display panel disposed in the opening.

8. The display device according to claim 1 , wherein the sub frame covers outline portions of a top surface of the display panel.

9. The display device according to claim 1 , wherein the sub frame has a cross section with one of a triangular shape or a bent configuration.

10. The display device according to claim 1 , wherein the main frame includes a metal.

11. The display device according to claim 1 , wherein the main frame has at least one step on its surface at the interface with the sub frame.

12. The display device according to claim 1 , wherein the sub frame has a cross section with a triangular shape.

13. The display device according to claim 1 , wherein the transparent thermoplastic resin includes an inorganic filler comprising at least one of glass fiber, carbon fiber, and metal fiber.

14. The display device according to claim 1 , wherein the main frame exposes a bottom surface of the supporting member.

15. The display device according to claim 1 , wherein the supporting member includes a main support surrounding the display panel and the backlight unit and a bottom cover covering the main support,
wherein the main frame is disposed on a side surface of the main support and exposes top and bottom surfaces of the main support,
wherein the sub frame covers the top surface of the main support exposed by the main frame, and
wherein the bottom frame covers the bottom surface of the main support exposed by the main frame.
