Method for controlling multiple subscreens on display device and display device therefor

Abstract

Provided is a method of displaying and controlling a plurality of sub-screens on a display apparatus. A plurality of sub-screens of a preset number are displayed on a screen of the display apparatus, and the sub-screens are respectively bound to different input devices, and a control instruction sent from the input devices to the display apparatus independently controls only a sub-screen bound to a particular input device, and does not affect other sub-screens that are not bound to the particular input device. A user of a display may use various services at the same time via the plurality of independent sub-screens displayed on the screen of the display apparatus, and a plurality of users may share a large screen of the display apparatus and view respectively desired content at the same time.

         5 . The display apparatus of  claim 4 , wherein the plurality of sub-screens comprise a first sub-screen and a second sub-screen, which are bound to a first input device, and
 wherein the program further comprises the instructions for executing operations comprising:   in response to the second user input from the first input device, changing the display mode between the multi-screen mode and the tap mode,   wherein in the multi-screen mode, all of the first sub-screen and the second sub-screen bound to the first input device are displayed on the display of the display apparatus and in the tab mode, one of the first sub-screen and the second sub-screen bound to the first input device, is displayed on the display of the display apparatus, the displayed one of the first sub-screen and the second sub-screen having a size corresponding to a sum of sizes of the first sub-screen and the second sub-screen.   
     
     
         6 . The display apparatus of  claim 5 , wherein the program further comprises the instructions for executing operations comprising:
 in the tap mode, in response to a third user input from the first input device, changing the display of the display apparatus from the first sub-screen and to second sub-screen, or from the second sub screen to the first sub screen.   
     
     
         7 . The display apparatus of  claim 5 , wherein the plurality of sub-screens further comprises a third sub-screen which is bound to a second input device, and the third sub-screen is not affected by a display mode change by using the first input device. 
     
     
         8 . A method of operating a display apparatus comprising:
 binding each of a plurality of sub-screens displayed on a display of the display apparatus to at least one of input devices configured to provide input to the display apparatus;   in response to receiving the input comprising a control instruction with respect to the display apparatus, determining a target sub-screen that is bound to an input device of the input devices that has transmitted the control instruction, from among the plurality of sub-screens; and   performing the control instruction for the determined target sub-screen, independently of other sub-screens,   wherein an identifier cursor indicating a location to which a command of the input device is to be input within a screen of the display apparatus, is distinguishable between when the identifier cursor locates within the sub-screen bound to the input device, and when the identifier cursor locates within the sub-screen not bound to the input device.
