Abstract

In a flat panel display having integral frame structure, features of a metal frame and a plastic support, which support, position, and fix each component, are incorporated as an integral frame structure, such that no additional structure component is needed for the flat panel display to assemble the backlight module and the panel module. The frame structure is assembled to the bottom cover via screw that can reduce defectiveness of repetitive processing. A concave section at the bottom of the frame structure can contain a control circuit board for the panel cell such that the control circuit board can be rerouted downward to the bottom of the frame structure. The space required at the light source side of the flat panel display can be reduced, hence leading to the flat panel display with thin frame at the light source side.

Claims

1. A flat panel display with thin frame, comprising:

a frame structure, comprising a first supportive part, a second supportive part, and a side portion, the first supportive part comprising a first surface and a second surface, and the second surface having an indented section formed indenting toward the first surface;

a reflector, a backlight unit, a light guide plate, and an optical film, wherein the reflector is configured on the first surface of the first supportive part, the backlight unit and the light guide plate are configured on the reflector, and the optical film is configured on the light guide plate;

a control circuit board contained in the indented section of the second surface of the frame structure, wherein the control circuit board and the second surface form a smooth surface and the first supportive part has uniform thickness with the control circuit board contained within;

a cell, placed on the second supportive part and electrically connected to the control circuit board via a flexible connecting wiring; and

a top frame, mounted to the cell and the side portion for fixing the cell.

2. The flat panel display of claim 1, wherein the frame structure is unitary structure.

3. The flat panel display of claim 1, wherein the reflector, the backlight unit and the light guide plate, and the optical film stack on the first supportive part in order along a first direction, the cell is placed on the second supportive part along the first direction, the side portion of the frame structure has the orientation of the first direction, and the flexible connecting wiring extends along the first direction to connect the control circuit board.

4. The flat panel display of claim 1, further comprising:

a first cover comprising a first assembling end, the frame structure assembled to the first cover; and

a second cover comprising a second assembling end and covering on the perimeter of the cell, the second cover assembled with the first cover by the second assembling end fixing to the first assembling end.

5. The flat panel display of claim 4, wherein the frame structure comprises a protrusion located at the side portion for being fixed to the first cover via a fixture so that the frame structure is assembled to the first cover.

6. The flat panel display of claim 1, wherein the flexible connecting wiring is a chip on film (COF) circuit.

7. The flat panel display of claim 1, wherein the backlight unit is a light emitting diode configured at a side of the light guide plate.

8. The flat panel display of claim 7, wherein the flexible connecting wiring extends along a light source side toward the indented section and connects to the control circuit board.

9. The flat panel display of claim 1, further comprising a cushion configured between the backlight unit and the cell.
