Electronic device and liquid crystal display thereof having a frame with one elastic positioning element

1. A liquid crystal display comprising:

a panel having at least one protrusion;

a frame having at least one elastic positioning element abutting against the protrusion to restrict the panel from moving on a base plane, wherein the panel is parallel to the base plane;

a bottom cover accommodating the frame and the panel; and

a top cover covering the bottom cover.

2. The liquid crystal display as claimed in claim 1 , wherein the frame further has a wall, and the elastic positioning element is extended from the wall.

3. The liquid crystal display as claimed in claim 1 , wherein the elastic positioning element is a hook engaging the protrusion.

4. The liquid crystal display as claimed in claim 3 , wherein an end of the hook has a lead angle.

5. The liquid crystal display as claimed in claim 1 , wherein the frame is made of plastic materials.

6. The liquid crystal display as claimed in claim 1 , wherein the frame is made of metal.

7. The liquid crystal display as claimed in claim 1 , wherein the panel has a displaying part and a non-displaying part adjoining the displaying part.

8. The liquid crystal display as claimed in claim 7 , wherein the non-displaying part has a top surface, and the protrusion is disposed on the top surface.

9. The liquid crystal display as claimed in claim 1 , wherein the protrusion is made of insulating materials.

10. The liquid crystal display as claimed in claim 9 , wherein the protrusion is a blank circuit board.

11. The liquid crystal display as claimed in claim 1 , wherein the protrusion has at least one lead angle.

12. The liquid crystal display as claimed in claim 1 further comprising:

an upper prism sheet disposed below the frame;

a bottom prism sheet disposed below the upper prism sheet;

a diffuser disposed below the bottom prism sheet;

a light guide plate disposed below the diffuser;

a reflector disposed below the light guide plate; and

a plurality of light emitting diodes toward the incident edge surface of light guide plate.

13. An electronic device comprising:

a liquid crystal display as claimed in claim 1 ; and

an input unit, coupled to the liquid crystal display, providing an input to the liquid crystal display to show images.

14. The electronic device as claimed in claim 13 , wherein the electronic device is a mobile phone, a digital camera, a personal digital assistant, a notebook computer, a desktop computer, a television, a car display, or a portable digital versatile disk player.
