Abstract

A multi-terminal screen combination method, device, and a computer storage medium. The method comprises the steps of: obtaining screen sizes of a reference terminal and a target terminal (S10); dividing, according to the screen dimensions, a picture to be displayed to generate display sub-pictures (S20); and displaying the display sub-picture corresponding to the reference terminal, and sending the other display sub-picture to the target terminal for display (S30). A function of combined display by means of a plurality of terminals is implemented.

First claim

What is claimed is:

1. A multi-terminal screen combination method, applied to a reference terminal, the multi-terminal screen combination method comprising steps of:
obtaining a screen size of the reference terminal and a screen size of a target terminal;
dividing a picture to be displayed, according to the screen size of the reference terminal and the screen size the target terminal, to generate a display sub-picture corresponding to the reference terminal and a display sub-picture corresponding to the target terminal;
displaying the display sub-picture corresponding to the reference terminal, and sending the display sub-picture corresponding to the target terminal to the target terminal for display;
upon receiving a display parameter adjustment instruction, adjusting a display parameter of the reference terminal based on the display parameter adjustment instruction, and forwarding the display parameter adjustment instruction to the target terminal, to enable the target terminal to perform display parameter adjustment based on the display parameter adjustment instruction synchronously with the reference terminal; and
upon detecting that the target terminal has received the display parameter adjustment instruction, forwarding the display parameter adjustment instruction to another target terminal, to enable the another target terminal to perform display parameter adjustment based on the display parameter adjustment instruction synchronously with the target terminal.

2. The multi-terminal screen combination method of claim 1 , wherein the step of obtaining the screen size of the reference terminal and the screen size of the target terminal comprises substeps of:
detecting one or more candidate terminals in a network where the reference terminal is located;
sending a test instruction to each of the one or more candidate terminals, and determining, as the target terminal, one of the one or more candidate terminals that returns confirmation information in response to the test instruction; and
obtaining the screen size of the reference terminal and the screen size of the determined target terminal.

3. The multi-terminal screen combination method of claim 2 , wherein the substep of sending the test instruction to each of the one or more candidate terminals, and determining, as the target terminal, one of the one or more candidate terminals that returns the confirmation information in response to the test instruction comprises:
sending the test instruction to each candidate terminal of the one or more candidate terminals to enable the each candidate terminal to display a confirmation interface, and determining, as the target terminal, one of the one or more candidate terminals that returns the confirmation information after receiving a confirmation instruction input by a user via the confirmation interface.

4. The multi-terminal screen combination method of claim 1 , wherein the step of dividing the picture to be displayed comprises substeps of:
dividing the picture to be displayed, according to the screen size of the reference terminal and the screen size of the target terminal, to generate a sub-picture corresponding to the reference terminal and a sub-picture corresponding to the target terminal;
obtaining resolution of the reference terminal and resolution of the target terminal; and
processing the sub-picture corresponding to the reference terminal, according to the resolution of the reference terminal, to generate the display sub-picture corresponding to the reference terminal, and processing the sub-picture corresponding to the target terminal, according to the resolution of the target terminal, to generate the display sub-picture corresponding to the target terminal.

5. The multi-terminal screen combination method of claim 4 , wherein the substep of processing the sub-picture corresponding to the reference terminal, and processing the sub-picture corresponding to the target terminal comprises:
obtaining resolution of the sub-picture corresponding to the reference terminal and resolution of the sub-picture corresponding to the target terminal, and determining a relationship between the resolution of the sub-picture corresponding to the reference terminal and the resolution of the reference terminal and a relationship between the resolution of the sub-picture corresponding to the target terminal and the resolution of the target terminal;
interpolating the sub-picture corresponding to the reference terminal to generate the display sub-picture corresponding to the reference terminal if the resolution of the sub-picture corresponding to the reference terminal is less than the resolution of the reference terminal, and interpolating the sub-picture corresponding to the target terminal to generate the display sub-picture corresponding to the target terminal if the resolution of the sub-picture corresponding to the target terminal is less than the resolution of the target terminal;
compressing the sub-picture corresponding to the reference terminal to generate the display sub-picture corresponding to the reference terminal if the resolution of the sub-picture corresponding to the reference terminal is greater than the resolution of the reference terminal, and compressing the sub-picture corresponding to the target terminal to generate the display sub-picture corresponding to the target terminal if the resolution of the sub-picture corresponding to the target terminal is greater than the resolution of the target terminal; and
taking the sub-picture corresponding to the reference terminal directly as the display sub-picture corresponding to the reference terminal if the resolution of the sub-picture corresponding to the reference terminal is equal to the resolution of the reference terminal, and taking the sub-picture corresponding to the target terminal directly as the display sub-picture corresponding to the target terminal if the resolution of the sub-picture corresponding to the target terminal is equal to the resolution of the target terminal.

6. The multi-terminal screen combination method of claim 4 , wherein the substep of dividing the picture to be displayed to generate the sub-picture corresponding to the reference terminal and the sub-picture corresponding to the target terminal comprises:
determining whether the screen size of the reference terminal is same as the screen size of the target terminal; and
equally dividing the picture to be displayed if the screen size of the reference terminal is same as the screen size of the target terminal, to generate the sub-picture corresponding to the reference terminal and the sub-picture corresponding to the target terminal.

7. The multi-terminal screen combination method of claim 1 , further comprising: after displaying the display sub-picture corresponding to the reference terminal, and sending the display sub-picture corresponding to the target terminal to the target terminal for display,
upon receiving a notification message or detecting that the target terminal has received the notification message, determining whether the notification message is a private message; and
simplifying the notification message for display if the notification message is the private message.

8. A non-transitory computer storage medium storing thereon a computer program executable by a processor to perform the multi-terminal screen combination method of claim 1 .
