Abstract

The present disclosure provides a display device and a driving method thereof. The display device includes a transparent cover plate; a display module, positioned on a side of the transparent cover plate and including a first display module and a second display module which are independent of each other; a first display control circuit, positioned on a side, facing away from the transparent cover plate, of the display module, and configured to independently control the first display module; and a second display control circuit, positioned on the side, facing away from the transparent cover plate, of the display module, and configured to independently control the second display module.

First claim

What is claimed is:

1. A display device, comprising:
a transparent cover plate;
a display module, positioned on a side of the transparent cover plate and comprising a first display module and a second display module;
a first display control circuit, positioned on a side, facing away from the transparent cover plate, of the display module and configured to independently control the first display module; and
a second display control circuit, positioned on the side, facing away from the transparent cover plate, of the display module and configured to independently control the second display module;
wherein the first display control circuit is electrically connected with the second display control circuit;
the first display control circuit is further configured to transmit a control signal to the second display control circuit;
the second display control circuit is further configured to control the second display module to cooperate with the first display module for corresponding displaying in response to the control signal; and
the first display control circuit comprises:
a first display mainboard; and
a master component, comprising:
a signal output interface;

the second display control circuit comprises:
a second display mainboard, comprising:
a signal input interface electrically connected with the signal output interface;

wherein the second display mainboard is configured to control the second display module to cooperate with the first display module for corresponding displaying in response to the control signal transmitted by the master component.

2. The display device according to claim 1 , wherein:
a Windows system is installed in the master component;
an Android system is installed in the first display mainboard and the second display mainboard; and
the signal output interface and the signal input interface are high definition multimedia interfaces.

3. The display device according to claim 1 , wherein the second display mainboard is further configured to disconnect a communication with the master component and independently control the second display module in response to a switching command of a user.

4. The display device according to claim 1 , wherein:
the first display control circuit further comprises:
a first display driver board;
wherein the first display mainboard transmits a display signal to the first display module through the first display driver board so as to control the first display module to display; and

the second display control circuit further comprises:
a second display driver board;
wherein, the second display mainboard transmits a display signal to the second display module through the second display driver board so as to control the second display module to display.

5. The display device according to claim 4 , wherein:
the first display control circuit further comprises:
a master adapter board, electrically connected with the master component;

wherein the master component is electrically connected with the first display mainboard through the master adapter board.

6. The display device according to claim 5 , wherein:
the first display control circuit further comprises:
a first display power panel;
wherein the first display power panel is electrically connected with the first display mainboard and the master adapter board and supplies power for the first display mainboard and the master adapter board;

the second display control circuit further comprises:
a second display power panel;
wherein the second display power panel is electrically connected with the second display mainboard and supplies power for the second display mainboard.

7. The display device according to claim 1 , wherein:
the first display control circuit further comprises an infrared remote-control receiving component; and
the second display control circuit further comprises a Bluetooth remote-control receiving component.

8. The display device according to claim 1 , wherein the first display control circuit and the second display control circuit are integrated on a same circuit board.

9. The display device according to claim 8 , wherein an orthographic projection of the second display module on the transparent cover plate covers an orthographic projection of the circuit board on the transparent cover plate.

10. The display device according to claim 1 , wherein the transparent cover plate is tempered glass.

11. A driving method of the display device according to claim 1 , comprising:
in a first working mode:
independently controlling, by the first display control circuit, the first display module to display, and
independently controlling, by the second display control circuit, the second display module to display.

12. The driving method according to claim 11 , further comprising:
in a second working mode:
transmitting, by the first display control circuit, a control signal to the second display control circuit, and
controlling, by the second display control circuit, the second display module to cooperate with the first display module for corresponding displaying in response to the control signal.

13. The driving method according to claim 12 , wherein in the second working mode:
a master component of the first display control circuit transmits the control signal to a second display mainboard of the second display control circuit; and
the second display mainboard controls the second display module to cooperate with the first display module for corresponding displaying in response to the control signal transmitted by the master component.

14. The driving method according to claim 13 , further comprising:
disconnecting, by the second display mainboard, a communication with the master component and independently controlling the second display module in response to a switching command of a user.
