Abstract
Provided is an electronic device including a touch panel, a communication unit, and a processing unit coupled to the touch control panel and the communication unit. The communication unit sends a detection signal and receives a response signal based on the detection signal. The processing unit determines an operation mode of the electronic device based on the response signal. The operation mode includes a first mode and a second mode. An input signal source of the electronic device of the first mode includes a finger. The input signal source of the second mode includes the finger and a stylus. When the response signal includes a pen-tip signal of the stylus and a pen-ring signal of the stylus, the processing unit determines whether to set the operation mode to the second mode according to the numerical relationship between the pen-tip signal and the pen-ring signal.
