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.
