Abstract

An electronic device and a method of operating a screen are disclosed; the touch screen has a display area and a non-display area, and the method includes steps as follows. First, a first sensing signal is generated when a designator controls a pointer on the non-display area. Then, a second sensing signal is generated when the pointer is moved from the non-display area to the display area. Then, a third sensing signal is generated when the pointer is moved on the display area. Last, a user interface is opened in the display area when a processing module receives the first, second and third sensing signals sequentially.

Claims

1. An electronic device, comprising:

a screen having a display area and a non-display area, wherein when a designator controls a pointer on the non-display area, a first sensing signal is generated, when the pointer is moved from the non-display area to the display area, a second sensing signal is generated, and when the pointer is moved on the display area, a third sensing signal is generated; and

a processing module for receiving the first, second and third sensing to signals that are sequentially generated by the screen to open a user interface in the display area.

2. The electronic device of claim 1, wherein the processing module commands the display area to display a menu based on the first sensing signal, wherein the menu has at least one the item.

3. The electronic device of claim 2, wherein the screen presets at least one trigger position corresponding to a place that the item is displayed, when the designator touches the trigger position, the third sensing signal is generated, so that the processing module for opening the user interface corresponding to the item in the display area.

4. The electronic device of claim 2, wherein when the designator drags the item on the display area and then moves away from the screen, the third sensing signal is generated, so that the processing module opens the user interface corresponding to the item in the display area.

5. The electronic device of claim 2, wherein when the designator continuously drags the item on the display area and changes directions of dragging the item, the third sensing signal is generated, so that the processing module opens the user interface corresponding to the item in the display area.

6. The electronic device of claim 5, wherein when the designator drags the item in a first direction and turns to a second direction, and when an included angle between the first and second directions is larger than 90°

, the third sensing signal is generated.

7. The electronic device of claim 2, wherein when the designator drags the item on the display area and then ceases moving the item over a predetermined period, the third sensing signal is generated, so that the processing module opens the user interface corresponding to the item in the display area.

8. The electronic device of claim 7, wherein the predetermined period is 2 seconds.

9. The electronic device of claim 1, wherein the screen has a touch sensor for sensing the designator'"'"'s motion for the screen, and the display area and the non-display area share the touch sensor, the touch sensor for generating the first sensing signal when the designator'"'"'s motion is to touch the non-display area, the touch sensor for generating the second sensing signal when the designator is moved from the non-display area to the display area, and the touch sensor for generating the third sensing signal when the designator is moved on the display area.

10. The electronic device of claim 1, wherein the screen has a first touch sensor for sensing the designator'"'"'s motion for the non-display area and a second touch sensor for sensing the designator'"'"'s motion for the display area, the first touch sensor is separated from the second touch sensor, the first touch sensor for generating the first sensing signal when the designator'"'"'s motion is to touch the non-display area, the first or second touch sensor for generating the second sensing signal when the designator is moved from the non-display area to the display area, and the second touch sensor for generating the third sensing signal when the designator is moved on the display area.

11. A method for operating the screen, the screen having a display area and a non-display area, the method comprising:

(a) generating a first sensing signal when a designator controls a pointer on the non-display area;

(b) generating a second sensing signal when the pointer is moved from the non-display area to the display area;

(c) generating a third sensing signal when the pointer is moved on the display area; and

(d) opening a user interface in the display area when a processing module sequentially receives the first, second and third sensing signals generated by the screen.

12. The method of claim 11, wherein the step (a) comprises:

commanding the display area to display a menu based on the first sensing signal, wherein the menu has at least one the item.

13. The method of claim 12, wherein the step (c) comprises:

presetting at least one trigger position corresponding to a place that the item is displayed, and generating the third sensing signal when the designator touches the trigger position, the step (d) comprises;

opening the user interface corresponding to the item in the display area.

14. The method of claim 12, wherein the step (c) comprises:

generating the third sensing signal when the designator drags the item on the display area and then moves away from the screen, the step (d) comprises;

opening the user interface corresponding to the item in the display area.

15. The method of claim 12, wherein the step (c) comprises:

generating the third sensing signal when the designator area continuously drags the item on the display and changes directions of dragging the item, the step (d) comprises;

opening the user interface corresponding to the item in the display area.

16. The method of claim 15, wherein the step (c) comprises:

when the designator drags the item from a first direction and turns to a second direction, and when an included angle between the first and second directions is larger than 90°

, generating the third sensing signal.

17. The method of claim 12, wherein the step (c) comprises:

generating the third sensing signal when the designator drags the item on the display area and then ceases moving the item over a predetermined period, the step (d) comprises;

opening the user interface corresponding to the item in the display area.

18. The method of claim 17, wherein the predetermined period is 2 seconds.

19. The method of claim 11, wherein the screen is a touch screen or a non-touch screen.
