Abstract

Embodiments of the disclosure provide a multi-screen display method and a display device including a curved surface display screen. The method is applied to the display device and includes the following steps. Position information of a preset folding line in the curved surface display screen is obtained when screen is bent according to the preset folding line, wherein the preset folding line is a boundary between the two adjacent sub-curved surface display screens formed thereby. A display interface of the screen is divided into a plurality of display sub-interfaces according to the position information, wherein a screen splitting line between two adjacent display sub-interfaces coincides with the preset folding line. The display contents selected by the user in the plurality of display sub-interfaces are obtained; and the selected display contents are displayed in the display sub-interfaces.

First claim

What is claimed is:

1. A multi-screen display method, applied to a display device comprising a curved surface display screen, the method comprising:
obtaining position information of a preset folding line in the curved surface display screen when the curved surface display screen is detected to be bent along the preset folding line and a portion of the display screen corresponding to the preset folding line protrudes out therefrom, wherein the curved surface display screen is bent and then split into at least two sub-curved surface display screens along the preset folding line, the preset folding line is a boundary between each two neighboring sub-curved surface display screens formed thereby;
dividing a display interface of the curved surface display screen into a plurality of display sub-interfaces according to the position information, wherein a screen splitting line between two neighboring display sub-interfaces coincides with the preset folding line there between;
obtaining the display contents selected by the user in the plurality of display sub-interfaces; and
displaying the selected display contents through the display sub-interfaces respectively;
detecting respective ambient brightness of each sub-curved surface display screen; and
adjusting respective display brightness of each sub-curved surface display screen according to respective ambient brightness thereof;
wherein before the step of obtaining position information of the preset folding line in the curved surface display screen, the multi-screen display method further comprises:
judging whether a multi-screen display function of the curved surface display screen is selected or not; and
acquiring the position information of the preset folding line in the curved surface display screen if the multi-screen display function of the curved surface display screen is selected, and outputting a prompt message for prompting the user to select the multi-screen display function of the curved surface display screen if the multi-screen display function of the curved surface display screen is not selected.

2. The multi-screen display method according to claim 1 , wherein the preset folding line is a vertical folding line, and the corresponding column pixel unit of the vertical folding line in the curved surface display screen is obtained as position information.

3. The multi-screen display method according to claim 1 , wherein after the step of obtaining the display contents selected by the user in the plurality of display sub-interfaces, the multi-screen display method further comprises:
judging whether the display contents have audio information;
selecting one of audio channels used by the curved surface display screen if the display contents have audio information; and
outputting the audio information through the selected audio channel.

4. The multi-screen display method according to claim 3 , wherein the preset folding line is a vertical folding line, and the corresponding column pixel unit of the vertical folding line in the curved display screen is obtained as position information.

5. The multi-screen display method according to claim 1 , wherein a sensor is used to detect whether the user bends the curved surface display screen along the preset folding line or not.

6. The multi-screen display method according to claim 5 , wherein the sensor is a pressure sensor, and when a pressure value detected by the pressure sensor reaches certain preset pressure threshold range, then it is judged that the user wants to bend and then split the curved surface display screen.

7. A display device, comprising:
a curved surface display screen;
a first acquiring module configured for acquiring position information of a preset folding line in the curved surface display screen when the curved surface display screen is detected to be bent by a user along the preset folding line, wherein the curved surface display screen is bent and then split into at least two sub-curved surface display screens according to the preset folding line, and the preset folding line is a boundary between each two adjacent sub-curved surface display screens formed thereby;
a dividing module configured for dividing a display interface of the curved surface display screen into a plurality of display sub-interfaces according to the position information, wherein a screen splitting line between two adjacent display sub-interfaces coincides with the preset folding line there between;
a second acquiring module configured for acquiring display contents selected by the user in the plurality of display sub-interfaces;
a display module configured for displaying the selected display contents through the display sub-interfaces;
at least two light detecting modules configured to detect respective ambient brightness of each sub-curved surface display screen; and
a brightness adjusting module configured to adjust display brightness of each sub-curved surface display screen according to respective ambient brightness thereof;
wherein the display device further comprises a first judging module and a first prompting module, the first judging module is configured for judging whether a multi-screen display function of the curved surface display screen is selected or not, and the first acquiring module is configured for acquiring the position information of the preset folding line on the curved surface display screen if the multi-screen display function of the curved surface display screen is selected, the first prompting module is configured for outputting a prompt message for prompting the user to select the multi-screen display function of the curved surface display screen if the multi-screen display function of the curved surface display screen is not selected.

8. The display device according to claim 7 , wherein the preset folding line is a vertical folding line, and the corresponding column pixel unit of the vertical folding line in the curved display screen is obtained as position information.

9. The display device according to claim 7 , wherein the display device further comprises a second judging module, a selecting module, and an output module; the second judging module is configured for judging whether the display contents have audio information, the selecting module is configured for selecting one of audio channels used by the curved surface display screen if the display contents have audio information, and the output module is configured for outputting the audio information by the selected audio channel.

10. The display device according to claim 9 , wherein the multiple audio channels are independent audio channels to respectively transmit different audio information simultaneously.

11. The display device according to claim 9 , wherein the preset folding line is a vertical folding line, and the corresponding column pixel unit of the vertical folding line in the curved display screen is obtained as position information.

12. The display device according to claim 7 , wherein the display device further comprises a sensor defined corresponding to the preset folding line, to detect the curved surface display screen is bent and split by a user along the preset folding line.

13. The display device according to claim 12 , wherein the sensor is a pressure sensor, and when a pressure value detected by the pressure sensor reaches certain preset pressure threshold range, then it is judged that the user wants to bend and then split the curved surface display screen.

14. The display device according to claim 7 , wherein the display device further comprises a screen splitting button defined on the curved surface display screen, and the scree
