Method and system for splitting a display zone of a screen, and computer program product

A system for splitting a display zone of a screen, said system being adapted for installation in an electronic device having a the screen and comprising:

• a detecting module for detecting pixels p0×q0 of the screen of the electronic device, wherein the detecting module comprises a first input terminal coupled to the screen of the electronic device and a first output terminal;
• a splitting processor connected to the first output terminal of said detecting module for receiving a splitting instruction instructions containing a splitting number n and for splitting the display zone of the screen into a main display region having p1×q1 pixels, and a number (n−1) of extension display regions, each having pi×qi pixels, where i=2˜n, wherein a total number of width pixels of adjacent ones of the main and extension display regions from left to right of the display zone of the screen is substantially equal to p0, and a total number of height pixels of adjacent ones of the main and extension display regions from top to bottom of the display zone of the screen is substantially equal to g0;
• an input module for inputting of the splitting instruction by a user, said input module including:
• one of a physical key adapted to be provided on a surface of the electronic device and a virtual key displayed on the screen, and
• a selection dialog box interface for display on the screen, said selection dialog box interface listing a plurality of selections for selection, wherein
• the plurality of selections comprise one or more of (a) operating interfaces open applications, (b) open files, and (c) open pages of open applications, and
• the splitting instruction identifies one or more selections of the plurality of selections, wherein the one or more selections were selected through the selection dialog box;
• and
• a display module for connection with the screen and said splitting processor, and for displaying the one or more selections in the main and extension display regions, respectively comprising a second input terminal and a second output terminal, wherein the second input terminal is coupled to said splitting processor, and the second output terminal is coupled to the screen of the electronic device,
• wherein a first splitting instruction is generated through operating one of the physical key and the virtual key once by a user, and the first splitting instruction contains a preset first value for the splitting number n, where n=2, wherein the display module is configured to display first content in the main display region and second content in one extension display region according to the first splitting instruction,
• wherein the selection dialog box interface is provided through operating one of the physical key and the virtual key twice in succession,
• wherein a second splitting instruction is generated by the user through the selection dialog box interface, the second splitting instruction containing a second value of the splitting number n and identifying two or more selections of the plurality of selections for display, wherein the two or more selections were selected through the selection dialog box interface, and wherein the display module is configured to display one of the selections in the main display region and display another of the selections in one extension display region,
• wherein the first and second content displayed according to the first splitting instruction are identified according to the following logic:
• detecting if an active file contains a plurality of pages;
• and if so, displaying one of the pages in the main display region and displaying another of the pages in one extension display region,
• wherein the logic for identifying the first and second content displayed according to the first splitting instruction further comprises:
• if the active file does not contain a plurality of pages, detecting if a plurality of files of an active application are opened;
• and if so, displaying one of the files opened in the active application in the main display region and displaying another of the files opening in the active application in one extension display region;
• and if not, displaying the active application in the main display region and displaying a most recently opened application in one extension display region.

A non-transitory computer-readable data storage medium comprising program instructions for causing a computer to execute a method for splitting a display zone of a screen of the computer, the method comprising:

• detecting a number of pixels p0×q0 of the screen;
• receiving a first splitting instruction, wherein the first splitting instruction is generated through operating one of a physical key and a virtual key once, and the first splitting instruction contains a preset splitting number n1, where n1=2;
• splitting the display zone of the screen into a main display region having p1×q1 pixels, and a number (n1−1) of extension display regions, each having pi×qi pixels, where i=2˜n1, wherein a total number of width pixels of adjacent ones of the main and extension display regions from left to right of the display zone of the screen is substantially equal to p0;
• displaying first content in the main display region and second content in one extension display region;
• receiving an activate option instruction, wherein the activate option instruction is generated through operating one of the physical key and the virtual key twice in succession;
• providing a selection dialog box interface in response to receipt of the activate option instruction, the selection dialog box interface listing a plurality of selections for selection, wherein the plurality of selections comprise one or more of (a) operating interfaces open applications, (b) open files, and (c) open pages of open applications;
• receiving a second splitting instruction through the selection dialog box interface, the second splitting instruction containing a splitting number n n2, the second splitting instruction identifying one two or more selections of the plurality of selections, wherein the one two or more selections were selected through the selection dialog box interface;
• splitting the display zone of the screen into a main display region having p1×q1 pixels, and a number (n−1) (n2−1) of extension display regions, each having pi×qi pixels, where i=2˜n i=2˜n2, wherein a total number of width pixels of adjacent ones of the main and extension display regions from left to right of the display zone of the screen is substantially equal to p0, and a total number of height pixels of adjacent ones of the main and extension display regions from top to bottom of the display zone of the screen is substantially equal to q0;
• and
• displaying the one or more selections in the main and extension display regions, respectively
• displaying one of the selections in the main display region, and displaying another of the selections in one extension display region according to the second splitting instruction,
• wherein the first and second content displayed according to the first splitting instruction are identified according to the following logic:
• detecting if an active file contains a plurality of pages;
• and if so, displaying one of the pages in the main display region and displaying another of the pages in one extension display region,
• wherein the logic for identifying the first and second content displayed according to the first splitting instruction further comprises:
• if the active file does not contain a plurality of pages, detecting if a plurality of files of an active application are opened;
• and if so, displaying one of the files opened in the active application in the main display region and displaying another of the files opened in the active application in one extension display region;
• and if not, displaying the active application in the main display region and displaying a most recently opened application in one extension display region.
