Abstract

A flat panel display includes a base, a supporting arm, a slide-bracket and a display module. The supporting arm has a first end and a second end. The first end of the supporting arm is hinged to the base so that the supporting arm can rotate relative to the base. The slide-bracket has a first end and a second end. The first end of the slide-bracket is hinged to the second end of the supporting arm so that the slide-bracket can rotate relative to the supporting arm. The display module is connected to the second end of the slide-bracket. Therefore, the display module can move relative to the base along with the movement of the supporting arm, and the display module can slide relative to the slide-bracket.

Claims

1. A flat panel display comprising:

a base;

a supporting arm with a first end and a second end, wherein the first end of the supporting arm is rotatably coupled to the base;

a slide-bracket with a first end and a second end, wherein the first end of the slide-bracket is rotatably coupled to the second end of the supporting arm; and

a display module slideably coupled to the second end of the slide-bracket, whereby the display module moves relative to the base by rotating the supporting arm, the slide-bracket and by sliding the display module relative to the slide-bracket.

2. The flat panel display according to claim 1, wherein the vertical distance between a bottom of the display module and the base is substantially constant by moving the supporting arm, the slide-bracket and the display module.

3. The flat panel display according to claim 1, wherein the display module forms an angle with the base by swing of the slide-bracket.

4. The flat panel display according to claim 1, the slide-bracket further comprising a cavity and a spring installed in the cavity, wherein the flat panel display further comprises:

a groove disposed on the back of the display module and opposite to the cavity;

a spring sheet in the groove; and

a steel ball disposed between the spring sheet and the spring, for stabilizing the display module in a predetermined position.

5. The flat panel display according to claim 4, the spring sheet further comprising a plurality of bulges aligned along the groove, wherein when the display module is driven by an external force to slide on the slide bracket, the steel ball rolls on the spring sheet, when the external force is released and the steel ball rests between two adjacent bulges, the display module is stabilized in the predetermined position

6. The flat panel display according to claim 5, wherein the cavity comprises a first opening, and the groove comprises a second opening, the flat panel display further comprising:

a first protruding part next to the first opening; and

a second protruding part, which is next to the second opening and engages with the first protruding part.

7. The flat panel display according to claim 1, the display module comprising a groove with a groove wall, and the slide-bracket comprising a resilient device in contact with the groove wall, wherein when the display module is driven by an external force to slide on the slide-bracket, the resilient device slides on the groove wall and when the external force is released, the resilient device is against the groove to stabilize the display module in a predetermined position.

8. The flat panel display according to claim 7, wherein the slide-bracket comprises a first protruding part, and the groove comprises a second protruding part engaging with the first protruding part of the slide-bracket.

9. A flat panel display comprising:

a base;

a supporting arm with a first end and a second end, wherein the first end of the supporting arm is rotatably coupled to the base;

a slide-bracket with a first end and a second end, wherein the first end of the slide-bracket is rotatably coupled to the second end of the supporting arm;

a load board with a front and a back, swinging synchronously with the slide-bracket, wherein the back of the load board connects to the second end of the slide-bracket; and

a display module slideably coupled to the front of the load board, whereby the display module moves relative to the base by rotation of the supporting arm, and the display module slides relative to the load board.

10. The flat panel display according to claim 9, wherein the vertical distance between a bottom of the display module and the base is substantially constant by moving the supporting arm, the slide-bracket, the load board and the display module.

11. The flat panel display according to claim 9, wherein the display module forms an angle with the base by the synchronous swing of the slide-bracket and the load board.

12. The flat panel display according to claim 9, further comprising:

a slider disposed on a back of the display module, wherein the slider comprises a cavity and a spring installed in the cavity;

a groove disposed on the front of the load board, wherein the groove is opposite to the cavity of the slider;

a spring sheet in the groove; and

a steel ball disposed between the spring sheet and the spring, for stabilizing the display module in a predetermined position.

13. The flat panel display according to claim 12, the spring sheet further comprising a plurality of bulges aligned along the groove, wherein when the display module is driven by an external force to slide on the load board, the steel ball rolls on the spring sheet;

when the external force is released and the steel ball rests between two adjacent bulges, the display module is stabilized in the predetermined position.

14. The flat panel display according to claim 13, wherein the cavity comprises a first opening, and the groove comprises a second opening, the flat panel display further comprising:

a first protruding part next to the first opening; and

a second protruding part, which is next to the second opening and engages with the first protruding part.

15. The flat panel display according to claim 9, the load board comprising a groove with a groove wall, and the display module comprising a slider with a resilient device in contact with the groove wall, wherein when the display module is driven by en external force to slide on the slide-bracket, the resilient device slides on the groove wall;

when the external force is released, the resilient device is against the groove to stabilize the display module in a predetermined position.

16. The flat panel display according to claim 15, wherein the slider comprises a first protruding part, and the groove comprises a second protruding part engaging with the first protruding part of the slider.
