Abstract

A flat panel display and backlight module thereof. The backlight module comprises a frame, a flexible printed circuit board, and at least one electrical connection port. The flexible printed circuit board is encircled by the frame. The electrical connection port is disposed on the flexible printed circuit board, connecting the flexible printed circuit board and an external printed circuit board.

Claims (25)

1. A backlight module, comprising:

a frame, having a rear side and a periphery side, comprising a plurality of parts forming a first opening in the rear side, wherein each one of the parts has an area and one of the parts has at least one second opening in the rear side;

a circuit board, disposed on the one of the parts, and an area of the circuit board is located inside the area of the one of the parts of the frame; and

at least one electrical connection port, disposed on the circuit board, connecting the circuit board and an external circuit board on the rear side, and not extending out of the periphery side of the frame;

wherein both of the at least one second opening of the frame, the at least one electrical connection port, and a place where the at least one electrical connection port connects to the external circuit board are arranged in one direction, and the direction is substantially perpendicular to a surface of the circuit board, and the surface is substantially paralleled to the rear side,

wherein the at least one electrical connection port, is corresponding to the at least one second opening and passes through the at least one second opening, and is exposed to the outside of the frame, wherein an area of the at least one electrical connection port is located inside the area of the one of the parts of the frame.

2. The backlight module of the claim 1 , wherein the at least one electrical connection port comprises an elastic conductor.

3. The backlight module of the claim 1 , wherein the at least one electrical connection port comprises a metal elastic plate.

4. The backlight module of the claim 1 , wherein the at least one electrical connection port is curved.

5. The backlight module of the claim 1 , wherein the at least one electrical connection port comprises bare copper.

6. The backlight module of the claim 1 , wherein the circuit board comprises a flexible printed circuit board or printed circuit board.

7. A flat panel display, comprising:

a backlight module of claim 1 ; and

an another circuit board comprising at least one another electrical connection port being connected with the electrical connection port in the backlight module of claim 1 .

8. A backlight module, comprising:

a frame, having a rear side and a periphery side, comprising at least one first opening and a picture frame-shaped area being projected on a plane and the picture frame-shaped area surrounding the at least one first opening in the rear side, wherein one portion of the picture frame-shaped area has at least one second opening thereinside, in the rear side;

a circuit board, disposed on the one portion of the picture frame-shaped area, and an area of the circuit board is located inside the one portion of the picture frame-shaped area; and

at least one electrical connection port, disposed on the circuit board, connecting the circuit board and an external circuit board on the rear side, and not extending out of the periphery side of the frame;

wherein both of the at least one second opening of the frame, the at least one electrical connection port, and a place where the at least one electrical connection port connects to the external circuit board are arranged in one direction, and the direction is substantially perpendicular to a surface of the circuit board, and the surface is substantially paralleled to the rear side,

wherein the at least one electrical connection port, is corresponding to the at least one second opening and passes through the at least one second opening, and is exposed to the outside of the frame, wherein an area of the at least one electrical connection port is located inside the one portion of the picture frame-shaped area.

9. The backlight module of the claim 8 , wherein the at least one electrical connection port comprises an elastic conductor.

10. The backlight module of the claim 8 , wherein the at least one electrical connection port comprises a metal elastic plate.

11. The backlight module of the claim 8 , wherein the at least one electrical connection port is curved.

12. The backlight module of the claim 8 , wherein the at least one electrical connection port comprises bare copper.

13. The backlight module of the claim 8 , wherein the circuit board comprises a flexible printed circuit board or printed circuit board.
