Abstract

A liquid crystal displaying device has an exterior housing. The liquid crystal displaying device comprises a liquid crystal displaying unit and a backlight unit. The liquid crystal displaying unit includes a frame, a liquid crystal displaying panel and a driving control circuit. The frame is arranged around the periphery of the liquid crystal displaying panel. The liquid crystal displaying panel has a displaying side. The driving control circuit is set inside the frame and is electrically connected to the liquid crystal displaying panel. The backlight unit includes a shell, at least one light-emitting element, and a power driver for driving the light-emitting element. The light-emitting element and the power driver are installed inside the shell, while the shell is assembled with the frame, such that the backlight unit is positioned at the side opposite to the displaying side of the liquid crystal displaying panel. The shell of the backlight unit and the frame of the liquid crystal displaying unit form the exterior housing of the liquid crystal displaying device.

Claims

1. A liquid crystal displaying monitor, which has an exterior housing, comprising:

a liquid crystal displaying unit, which comprises a frame, a liquid crystal displaying panel and a driving control circuit, wherein the frame is disposed along the periphery of the liquid crystal displaying panel, the liquid crystal displaying panel has a displaying side, and the driving control circuit is set inside the frame and is electrically connected to the liquid crystal displaying panel;

a backlight unit, which comprises a shell, at least one light-emitting element, and a power driver for driving the light-emitting element, wherein the light-emitting element and the power driver are installed within a volume defined by the shell, the shell is assembled with the frame such that the backlight unit is positioned at the side opposite to the displaying side of the liquid crystal displaying panel, and the shell of the backlight unit and the frame of the liquid crystal displaying unit together form the exterior housing of the liquid crystal displaying monitor; and

a stand, which supports the frame and is directly connected to the frame and is not directly connected to the backlight unit.

2. The liquid crystal displaying monitor of claim 1, wherein the frame comprises a first frame portion and a second frame portion, and the first frame portion and the second frame portion connect with each other to form an accommodating space.

3. The liquid crystal displaying monitor of claim 2, wherein the driving control circuit is disposed in the accommodating space and electrically connects to the liquid crystal displaying panel for driving and controlling the liquid crystal displaying panel.

4. The liquid crystal displaying monitor of claim 1, further comprising:

at least one screw-connection component, which connects the frame to the shell of the backlight unit such that the backlight unit is assembled with the frame.

5. The liquid crystal displaying monitor of claim 4, wherein the frame comprises a first frame portion and a second frame portion, and the screw-connection component connects the second frame portion of the frame to the shell of the backlight unit such that the backlight unit is assembled with the second frame portion of the frame.

6. The liquid crystal displaying monitor of claim 1, wherein the frame further comprises a first connecting portion, the shell of the backlight unit has a second connecting portion opposite to the frame, and the first connecting portion connects with the second connecting portion for assembling the backlight unit and the frame.

7. The liquid crystal displaying monitor of claim 6, wherein the frame comprises a first frame portion and a second frame portion, and the first connecting portion is disposed on the second frame portion.

8. The liquid crystal displaying monitor of claim 1, further comprising:

at least one riveting component, which connects the frame to the shell of the backlight unit such that the backlight unit is assembled with the frame.

9. The liquid crystal displaying monitor of claim 8, wherein the frame comprises a first frame portion and a second frame portion, and the riveting component connects the second frame portion of the frame to the shell of the backlight unit such that the backlight unit is assembled with the second frame portion of the frame.

10. The liquid crystal displaying monitor of claim 1, wherein the backlight unit is a direct backlight unit.

11. The liquid crystal displaying monitor of claim 1, wherein the backlight unit further comprises a power cable, and one end of the power cable electrically connects to the power driver.

12. The liquid crystal displaying monitor of claim 11, wherein the other end of the power cable electrically connects to an external power source.

13. The liquid crystal displaying monitor of claim 11, wherein the other end of the power cable electrically connects to the liquid crystal displaying unit.

14. The liquid crystal displaying monitor of claim 1, further comprising a signal connecting line, wherein one end of the signal connecting line electrically connects to the power driver, and the other end of the signal connecting line electrically connects to the driving control circuit.

15. The liquid crystal displaying monitor of claim 1, wherein the light-emitting element is a cold cathode fluorescent lamp (CCFL).
