Multi-screen display method and display device

A display device, comprising:

• a curved surface display screen;
• a first acquiring module configured for acquiring position information of a preset folding line defined in the curved surface display screen, when it is detected that the curved surface display screen is bent by a user according to 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;
• a second acquiring module configured for acquiring adjusted display contents selected by the user in the plurality of display sub-interfaces;
• a display module configured for displaying the adjusted display contents selected in the display sub-interfaces through the display sub-interfaces;
• a memory configured for storing an original resolution of the display module;
• a connecting port connected to a source device by an image transmission line, and being configured to receive a multi-screen display request sent from the source device through the image transmission line and the adjusted display contents;
• and
• a display controller coupled to the display module, the memory, and the connecting port, and being configured to differentiate the original resolution of the curved surface display screen into a plurality of adjusting resolutions according to a screen amount in the multi-screen display request, and transmit resolution data to the source device, and respectively display the adjusted display contents on the plurality of display sub-interfaces.

A multi-screen display method, applied to a display device comprises a curved surface display screen and the curved surface display screen is connected to a source device by an image transmission line, the method comprising:

• acquiring position information of a preset folding line defined in the curved surface display screen, when screen bending and splitting carried out on the curved surface display screen by a user according to the preset folding line is detected 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 according to the preset folding line, and the preset folding line is a boundary between each two adjacent sub-curved surface display screens formed by the screen bending and splitting;
• 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;
• receiving a multi-screen display request sent from the source device through the image transmission line;
• transferring an original resolution of the curved surface display screen into a plurality of adjusting resolutions according to a screen amount in the multi-screen display request and transmitting resolution data recorded the plurality of adjusting resolutions respectively to the source device;
• adjusting the resolutions of display contents selected by the user in the plurality of display sub-interfaces by the source device according to the resolution data, to accord with the plurality of adjusting resolutions respectively;
• acquiring the adjusted display contents selected by the user in the plurality of display sub-interfaces from the source device through the image transmission line;
• and
• displaying the adjusted display contents selected in the display sub-interfaces through the display sub-interfaces;
• wherein before the step of acquiring position information of a preset folding line defined 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 on 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;
• wherein after the step of acquiring the adjusted 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 by the selected audio channel;
• wherein the preset folding line is a vertical folding line;
• and
• acquiring position information of a preset folding line defined in the curved surface display screen specifically comprises acquiring pixel units of a corresponding column of the vertical folding line in the curved surface display screen.
