Abstract

The present invention discloses a touch method for palm rejection and an electronic device using the same. The electronic device comprises a touch panel and a control unit, wherein the touch panel has a first detection region and includes a first operation mode and second operation mode, and the touch panel correspondingly performs a clicking or sliding motion by detection at the second operation mode. The control unit is electrically connected to the touch panel, when the first detection region detects a motion at the first operation mode, the touch panel generates a detecting signal correspondingly to be transmitted to the control unit, and then the control unit generates a control signal to the touch panel. Thus, the touch panel activates the first operation mode and ceases the second operation mode correspondingly provided that no motion is detected for a first period of time at the second operation mode.

Claims

1. An electronic device comprising:

a touch panel having a first detection region and including a first operation mode and a second operation mode, the touch panel correspondingly performing a clicking or sliding motion by detection at the second operation mode; and

a control unit electrically connected to the touch panel, when the first detection region detects a motion at the first operation mode, the touch panel generates a detecting signal correspondingly to be transmitted to the control unit, the control unit determines based on the detecting signal so as to generate a control signal to the touch panel, and the touch panel activates the second operation mode and ceases the first operation mode according to the control signal, wherein the touch panel activates the first operation mode and ceases the second operation mode correspondingly provided that no motion is detected for a first period of time at the second operation mode.

2. The electronic device as claimed in claim 1, wherein the motion by detection in the first detection region at the first operation mode is a pressed motion lasted for a second period of time.

3. The electronic device as claimed in claim 1, wherein the touch panel has a second detection region, and the motion detected in the first detection region at the first operation mode is the sliding motion extended from the first detection region to the second detection region.

4. The electronic device as claimed in claim 3, wherein the first detection region is distinguished from the second detection region by different lines, colors or materials.

5. The electronic device as claimed in claim 3, wherein the first detection region is distinguished from the second detection region by installed locations on the touch panel.

6. The electronic device as claimed in claims 1, further comprising a display unit electrically connected to the control unit and the touch panel, wherein the display unit is used for displaying the touch panel operated at the first or second operation mode.

7. The electronic device as claimed in claims 2, further comprising a display unit electrically connected to the control unit and the touch panel, wherein the display unit is used for displaying the touch panel operated at the first or second operation mode.

8. The electronic device as claimed in claims 3, further comprising a display unit electrically connected to the control unit and the touch panel, wherein the display unit is used for displaying the touch panel operated at the first or second operation mode.

9. The electronic device as claimed in claims 4, further comprising a display unit electrically connected to the control unit and the touch panel, wherein the display unit is used for displaying the touch panel operated at the first or second operation mode.

10. The electronic device as claimed in claims 5, further comprising a display unit electrically connected to the control unit and the touch panel, wherein the display unit is used for displaying the touch panel operated at the first or second operation mode.

11. A touch method for palm rejection adapted to an electronic device having a touch panel, the method comprising:

presetting the touch panel as a first operation mode;

detecting a motion in a first detection region of the touch panel at the first operation mode, the touch panel generating a detecting signal correspondingly to be transmitted to a control unit of the electronic device;

determining by the control unit whether the motion is an activating command according to the detecting signal, if the motion is the activating command, the control unit generates a control signal to the touch panel correspondingly;

driving the touch panel to activate a second operation mode and cease the first operation mode correspondingly according to the control signal, and performing a clicking or sliding motion by detection at the second operation mode correspondingly; and

controlling the touch panel by the control unit to activate the first operation mode and cease the second operation mode correspondingly provided that no motion is detected for a first period of time at the second operation mode, wherein the control unit controls the touch panel not to perform a function corresponding to the detecting signal provided that the control unit determines that the motion is not the activating command.

12. The touch method as claimed in claim 11, wherein in the step of detecting the motion in the first detection region of the touch panel at the first the motion, the motion by detection in the first detection region is a pressed motion lasted for a second period of time.

13. The touch method as claimed in claim 11, wherein in the step of detecting the motion in the first detection region of the touch panel at the first the motion, the motion by detection in the first detection region is the sliding motion extended from the first detection region to the second detection region.

14. The touch method as claimed in claims 11, further comprising:

displaying the touch panel operated at the first or second operation mode by a display unit.

15. The touch method as claimed in claims 12, further comprising:

displaying the touch panel operated at the first or second operation mode by a display unit.

16. The touch method as claimed in claims 13, further comprising:

displaying the touch panel operated at the first or second operation mode by a display unit.
