## Abstract

A method of controlling a display device including a touch screen is provided. The method includes displaying, on the touch screen, a plurality of windows respectively corresponding to executing applications, such that the windows do not overlap each other, displaying a plurality of boundary lines differentiating the plurality of windows, and a center button disposed at an intersection point of the plurality of boundary lines, receiving, through the touch screen, an input of a window size change command to change a size of at least one of the plurality of windows, and resizing and displaying at least one of the plurality of windows in correspondence to the window size change command.

## Claims

### Claim 1

A method of controlling an electronic device comprising a touch screen, the method comprising:
displaying a first execution screen of a first application having a first type in a first window and a second execution screen of a second application having a second type in a second window, wherein the first window and the second window do not overlap each other and wherein a boundary line splits the first window and the second window;
detecting a touch interaction on at least part of the boundary line;
according to a movement of the touch interaction on the boundary line, gradually decreasing a size of the first window and moving the boundary line and displaying the first execution screen of the first application in a reduced first window; and
based at least on the reduced first window having a size equal to a threshold according to the decrease of the size of the first window, displaying a third execution screen of the first application having a third type in the first window in replacement with the first execution screen of the first application.

### Claim 2 (depends on 1)

The method as claimed in claim 1, further comprising:
displaying the second execution screen of the second application in an enlarged second window,
wherein the reduced first window and the enlarged second window do not overlap each other, and
wherein the boundary line splits the reduced first window and the enlarged second window.

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein a content of the third execution screen having the third type is an alternate information of a content of the first execution screen of the first application.

### Claim 4

An electronic device comprising:
a touch screen; and
at least one processor configured to:
display a first execution screen of a first application having a first type in a first window and a second execution screen of a second application having a second type in a second window, wherein the first window and the second window do not overlap each other and wherein a boundary line splits the first window and the second window,
detect a touch interaction on at least part of the boundary line,
according to a movement of the touch interaction on the boundary line, gradually decrease a size of the first window and move the boundary line, and display the first execution screen of the first application in a reduced first window, and
based at least on the reduced first window having a size equal to a threshold according to the decrease of the size of the first window, display a third execution screen of the first application having a third type in the first window in replacement with the first execution screen of the first application.

### Claim 5 (depends on 4)

The electronic device as claimed in claim 4, wherein the at least one processor is further configured to:
display the second execution screen of the second application in an enlarged second window,
wherein the reduced first window and the enlarged second window do not overlap each other, and
wherein the boundary line splits the reduced first window and the enlarged second window.

### Claim 6 (depends on 4)

The electronic device as claimed in claim 4, wherein a content of the third execution screen having the third type is an alternate information of a content of the first execution screen of the first application.

### Claim 7

A non-transitory computer-readable medium storing instructions, that when executed by a processor, causes the processor to:
display a first execution screen of a first application having a first type in a first window and a second execution screen of a second application having a second type in a second window, wherein the first window and the second window do not overlap each other and wherein a boundary line splits the first window and the second window;
detect a touch interaction on at least part of the boundary line;
according to a movement of the touch interaction on the boundary line, gradually decrease a size of the first window and move the boundary line, and display the first execution screen of the first application in a reduced first window; and
based at least on the reduced first window having a size equal to a threshold according to the decrease of the size of the first window, display a third execution screen of the first application having a third type in the first window in replacement with the first execution screen of the first application.

### Claim 8 (depends on 7)

The non-transitory computer-readable medium as claimed in claim 7, wherein the instructions further cause the electronic device to:
display the second execution screen of the second application in an enlarged second window,
wherein the reduced first window and the enlarged second window do not overlap each other, and
wherein the boundary line splits the reduced first window and the enlarged second window.

### Claim 9 (depends on 7)

The non-transitory computer-readable medium as claimed in claim 7, wherein a content of the third execution screen having the third type is an alternate information of a content of the first execution screen of the first application.
