Abstract

An electronic device capable of touch event processing is provided. The electronic device includes first and second surfaces oriented in different directions, the second surface being narrower than the first surface, a touchscreen display including a touch panel, and having a first section exposed through the first surface and a second section exposed through the second surface, a processor electrically connected with the touchscreen display, and a memory that stores instructions that cause, when executed, the processor to activate the touch panel, to detect a first touch event on one of the first section and the second section, to detect a second touch event on the other section after detection of the first touch event, to remove one of the first touch event and the second touch event, and to perform a function according at least partly to the remaining touch event.

Claims

1. An electronic device comprising:

a housing including a first surface oriented in a first direction, and a second surface extending from the edge of the first surface in a second direction different from the first direction and being narrower than the first surface;

a touchscreen display including a touch panel, and having a first section exposed through the first surface and a second section exposed through the second surface;

a processor electrically connected with the touchscreen display; and

a memory electrically connected with the processor,

wherein the memory stores instructions that cause, when executed, the processor to;

activate the touch panel,

detect a first touch event on the second section of the touchscreen display,

temporarily store the first touch event,

detect a second touch event on the first section or the second section after detection of the first touch event,

if the second touch event is detected on the first section, remove the first touch event, and perform a function according to the second touch event,

if the second touch event is detected on the second section, temporarily store the second touch event after removing the first touch event,

perform a function according to the second touch event and a third touch event in response to detecting the third touch event within a preset time after detection of the second touch event, and

remove the second touch event and the third touch event in response to detecting the third touch event after the preset time after detection of the second touch event.

2. The electronic device of claim 1, wherein the second surface is partially bent.

3. The electronic device of claim 1, wherein the first surface includes a first side of a first length, a second side of a second length longer than the first length, a third side of the first length, and a fourth side of the second length,

wherein the first side is perpendicular to the second side and the fourth side and is parallel with the third side, and

wherein an edge of the second surface comprises the second side.

4. The electronic device of claim 3, wherein the second surface of the touchscreen display is extended from the edge of the first surface.

5. The electronic device of claim 1, wherein the first surface is flat.

6. The electronic device of claim 1, wherein the instructions cause the processor to determine which one of the first touch event and the second touch event has occurred on the first section, to perform a function according at least partly to the touch event having occurred on the first section, and to remove the remaining touch event having occurred on the second section.

7. The electronic device of claim 1, wherein, when third touch event is detected on the first section, the instructions cause the processor to remove the second touch event and to perform a function according at least partly to the third touch event.

8. The electronic device of claim 1, wherein, when the first touch event is detected on the first section and the second touch event is detected on the second section, the instructions cause the processor to remove the second touch event and to perform a function according at least partly to the first touch event.

9. An electronic device comprising:

a housing that includes a first surface oriented in a first direction, and a second surface extending from the edge of the first surface in a second direction different from the first direction and being narrower than the first surface;

a touchscreen display including a touch panel, and having a first section exposed through the first surface and a second section exposed through the second surface;

a processor electrically connected with the touchscreen display; and

a memory electrically connected with the processor,

wherein the memory stores instructions that cause, when executed, the processor to;

activate the touch panel, to

detect a first touch event on a first region of the second section of the touchscreen display,

detect a second touch event on a second region of the second section different from the first region after detection of the first touch event,

determine if an occurrence time between the detection of the first touch event and the detection of the second touch event is less than a predetermined threshold,

use the first touch event while deleting the second touch event if it is determined that the occurrence time between the detection of the first touch event and the detection of the second touch event is not less than the predetermined threshold, and

use the second touch event while deleting the first touch event if it is determined that the occurrence time between the detection of the first touch event and the detection of the second touch event is less than the predetermined threshold.

10. The electronic device of claim 9, wherein the instructions cause the processor to determine whether at least one of the first touch event and the second touch event constitutes a gesture event, and to perform a function according at least partly to the determined touch event.

11. The electronic device of claim 9, wherein the second touch event corresponds to a touch gesture involving movement from a touch point of the first touch event without touch-release.

12. A method of touch event processing in an electronic device, the method comprising:

activating a touch screen display;

detecting a first touch event on a second section of the touchscreen display;

temporarily storing the first touch event;

detecting a second touch event on a first section or the second section of the touch screen display after detection of the first touch event;

if the second touch event is detected on the first section, removing the first touch event, and performing a function according to the second touch event;

if the second touch event is detected on the second section, temporarily storing the second touch event after removing the first touch event;

performing a function according to the second touch event and a third touch event in response to detecting the third touch event within a preset time after detection of the second touch event; and

removing the second touch event and the third touch event in response to detecting the third touch event after the preset time after detection of the second touch event.

13. The method of claim 12, wherein the second surface is partially bent.

14. The method of claim 12, wherein a first surface of the electronic device includes a first side of a first length, a second side of a second length longer than the first length, a third side of the first length, and a fourth side of the second length, wherein the first side is perpendicular to the second side and the fourth side and is parallel with the third side, and wherein an edge of a second surface of the electronic device comprises the second side.

15. The method of claim 14, wherein the second surface of the touchscreen display is extended from the edge of the first surface.

16. The method of claim 12, wherein the first surface is flat.

17. The method of claim 12, further comprising:

determining which one of the first touch event and the second touch event has occurred on the first section; and

performing a function according at least partly to the touch event having occurred on the first section, and removing the remaining touch event having occurred on the second section.

18. The method of claim 12, further comprising removing the second touch event and performing a function according at least partly to the third touch event when the third touch event is detected on the first section.

19. The method of claim 12, further comprising removing the second touch event and performing a function according at least partly to the first touch event when the first touch event is detected on the first section and the second touch event is detected on the second section.
