Abstract

Disclosed is a dual display apparatus to display first and second display screens. The dual display apparatus includes a display unit to display the first and second display screens, and an input unit to receive a first or second multi-touch gesture signal. The first multi-touch gesture signal includes pinch-in signals to expand content displayed in the first display screen, and the second multi-touch gesture signal includes a sliding touch to expand the first display screen or to change the first display screen to the entire display screen. The dual display apparatus further includes a screen adjustment module to expand content displayed in the first display screen in response to the first multi-touch gesture signal, and to display the expanded first display screen or the changed entire display screen in response to the second multi-touch gesture signal. The first and second multi-touch gesture signals are input in succession via a touch.

receiving a second multi-touch gesture signal, wherein the second multi-touch gesture signal includes a sliding touch to expand the size of the first display screen or to change the first display screen to the entire display screen; and

displaying the expanded first display screen or the changed entire display screen in response to the input second multi-touch gesture signal,

wherein the first multi-touch gesture signal and the second multi-touch gesture signal are input in succession via a continuous touch.

2. A dual display apparatus to display first and second display screens, the apparatus comprising:

a display unit to display the first and second display screens;

an input unit to receive a first multi-touch gesture signal or a second multi-touch gesture signal, wherein first multi-touch gesture signal includes pinch-in signals to expand the size of content displayed in the first display screen, and the second multi-touch gesture signal includes a sliding touch to expand the size of the first display screen or to change the first display screen to the entire display screen; and

a screen adjustment module to expand the size of content displayed in the first display screen in response to the first multi-touch gesture signal, and to display the expanded first display screen or the changed entire display screen in response to the second multi-touch gesture signal,

wherein the first multi-touch gesture signal and the second multi-touch gesture signal are input in succession via a continuous touch.

3. The dual display apparatus according to claim 2, wherein the first and second display screens are divided from each other by an imaginary boundary line, and the imaginary boundary line is represented by any one of a dotted line, a solid line, and an area having a predetermined size.

4. The dual display apparatus according to claim 3,

wherein the first multi-touch gesture signal includes a first touch and a second touch that are input at the same time,

wherein the second multi-touch gesture signal includes a start touch and an end touch, the second multi-touch gesture signal being input by a sliding touch starting from the start touch to the end touch across the imaginary boundary line.

5. The dual display apparatus according to claim 4, wherein the screen adjustment module expands the size of the first display screen or changes the first display screen to the entire display screen by sensing the second multi-touch gesture signal based on a distance from the start touch to the end touch and a sliding input time from the start touch to the end touch, and moving a position of the imaginary boundary line to a position of the end touch or deforming the imaginary boundary line to thereby generate a new imaginary boundary line at the position of the end touch.

6. The dual display apparatus according to claim 5, wherein the screen adjustment module changes the first display screen to the entire display screen if a sliding distance of the second multi-touch gesture signal exceeds a preset distance.

7. The dual display apparatus according to claim 5, wherein the screen adjustment module expands the size of the first display screen based on the position of the end touch if a sliding distance of the second multi-touch gesture signal is less than a preset distance.

8. The dual display apparatus according to claim 7, wherein the screen adjustment module reduces the size of the second display screen based on the position of the end touch.

9. The dual display apparatus according to claim 8, wherein the display unit displays the expanded first display screen and the reduced second display screen at a time.

10. The dual display apparatus according to claim 4,

wherein the input unit receives third multi-touch gesture signal for rotation of the expanded first display screen or the changed entire display screen, the third multi-touch gesture including tapping and holding,

wherein the screen adjustment module rotates the expanded first display screen or the entire display screen in response to the third multi-touch gesture, and

the display unit displays the rotated first display screen or the entire display screen.

11. The dual display apparatus according to claim 4,

wherein the input unit receives a fourth multi-touch gesture signal to reduce the size of the expanded first display screen or to change the entire display screen to the first display screen, and

wherein the screen adjustment module reduces the size of the expanded first display screen or changes the entire display screen to the first display screen in response to the input fourth multi-touch gesture signal.

12. The dual display apparatus according to claim 11, wherein the fourth multi-touch gesture signal includes pinch-out signals and a sliding touch.

13. The dual display apparatus according to claim 12, wherein the screen adjustment module changes the entire display screen to the first display screen if the fourth multi-touch gesture signal includes the pinch-out signals or if a sliding distance of the fourth multi-touch gesture signal exceeds a preset distance.

14. The dual display apparatus according to claim 13, wherein the screen adjustment module reduces the size of the expanded first display screen by deforming a boundary line of the expanded first display screen or moving a position of the boundary line of the expanded first display screen if the sliding distance of the fourth multi-touch gesture signal is less than the preset distance.

15. The dual display apparatus according to claim 4, wherein the first and second display screens include an indicator.

16. The dual display apparatus according to claim 15, wherein the indicator receives the second multi-touch gesture signal.

17. The dual display apparatus according to claim 16,

wherein the indicator receives a fourth multi-touch gesture signal to reduce the size of the expanded first display screen or to change the entire display screen to the first display screen, and

wherein the screen adjustment module reduces the size of the expanded first display screen or changes the entire display screen to the first display screen in response to the input fourth multi-touch gesture signal.

18. A dual display method to display a first display screen that displays first content and a second display screen that displays second content, the method comprising:
