Claim Text:
1. A near field communication method of a touch terminal, which is used for near field communication between a first touch terminal and a second touch terminal, the method comprising: the first touch terminal and the second touch terminal obtaining a user operation of opening near field communication function, and opening the near field communication function; the user operation of opening the near field communication function comprising the user operation for selecting in a relevant menu of data to be transmitted and the user operation for opening the near field communication function in touch terminal system settings; the first touch terminal detecting whether the second touch terminal is located in a communication range of the first touch terminal, if located, the first touch terminal sends a wireless communication request of establishment of the near field communication to the second touch terminal through a near field electric field; the first touch terminal entering a proximity detection mode in a sending mode for detecting whether the second touch terminal is located in the communication range of the first touch terminal; the second touch terminal detecting whether the first touch terminal is located in the communication range of the second touch terminal, if located, the second touch terminal receives the wireless communication request of establishment of the near field communication sent by the first touch terminal through the near field electric field; the second touch terminal entering the proximity detection mode in a receiving mode for detecting whether the first touch terminal is located in the communication range of the second touch terminal; the second touch terminal receiving the wireless communication request of establishment of the near field communication sent by the first touch terminal through the near field electric field; the second touch terminal sending an interference source peripherals closing signal to a main control chip, and informing the main control chip to close the interference source peripherals; the first touch terminal and the second touch terminal establishing a wireless connection by touching the near field electric field, and exchanging data; wherein a proximity detection duration of the first touch terminal is not less than a sum of touch detection duration and two proximity detection duration of the second touch terminal; when a touch detection and a proximity detection cannot be performed simultaneously, the touch detection and the proximity detection can be performed alternately after entering the proximity detection mode.
