Abstract

The present invention relates to a display device comprising a mounting board and a display panel mounted on the mounting board and comprising a plurality of display modules arranged in an array, and further comprising a control module and a plurality of driving modules corresponding to the display modules. The control module is capable of controlling the driving modules to drive the corresponding display modules to extend. When the display device is powered on, the control module is electrically coupled to the driving module such that the driving module receives a signal from the control module and controls the display module to extend in response to the signal; when the driving module is started, the corresponding display module moves along with the driving module and automatically extends, facilitating the maintenance of the display device.

First claim

What is claimed is:

1. A display device comprising a mounting board and a display panel mounted on the mounting board and comprising a plurality of display modules arranged in an array, wherein:
the display device further comprises a control module and a plurality of driving modules corresponding to the display modules,
the driving modules are arranged between the mounting board and the corresponding display modules and coupled to the mounting board and the display modules respectively, and
the control module is coupled to the driving modules and controls the driving modules to drive the corresponding display modules to extend, and
wherein the driving modules comprise a self-locking switch, a lever and a power unit,
the self-locking switch is arranged on the mounting board,
the lever is arranged between the display modules and the self-locking switch to engage with the self-locking switch, and
the power unit is coupled to the lever for powering the lever.

2. The display device according to claim 1 , wherein the control module is further arranged to control the driving modules to drive the corresponding display modules to retract.

3. The display device according to claim 1 , wherein:
a positioning protrusion is arranged on a side of the display modules facing the mounting board, and
a positioning hole corresponding to the positioning protrusion is arranged on the mounting board.

4. The display device according to claim 1 , wherein the mounting board and the display modules are respectively provided with corresponding limiting modules for limiting movement of the display modules in a direction perpendicular to the mounting board in a range.

5. The display device according to claim 1 , wherein:
the driving modules comprise an asynchronous motor and a coupling unit,
the coupling unit is coupled to the asynchronous motor and the corresponding display modules respectively, and
the asynchronous motor is arranged to drive the corresponding display modules to extend and retract through the coupling unit.

6. The display device according to claim 1 , wherein:
the driving modules comprise a hydraulic lifter and a lift unit,
the hydraulic lifter is coupled to the lift unit and the control module respectively and drives the lift unit through the hydraulic pressure, and
the lift unit is coupled to the corresponding display modules.

7. The display device according to claim 1 , wherein:
the driving modules comprise a magnetic telescoping mechanism and a telescoping unit,
the magnetic telescoping mechanism is coupled to the telescoping unit and the control module respectively and drives the telescoping unit through magnetic force, and
the telescoping unit is coupled to the corresponding display modules.

8. The display device according to claim 1 , wherein the mounting board is provided with a plurality of wireless receiving modules, each of which is coupled to one of the corresponding driving modules.
