CAPACITIVE TOUCH SCREEN TERMINAL AND NEAR FIELD COMMUNICATION METHOD AND SYSTEM THEREOF

摘要

A capacitive touch screen terminal and a near field communication method and system thereof are provided. In the method and the system, the near field communication is realized through multiplexing driving electrodes and sensing electrodes of a touch sensor in a capacitive touch screen by a transmitting terminal and a receiving terminal, and a frequency sequence is used as a carrier for data transmission. It may be suitable for the near field communication between two capacitive touch screen terminals having a large size difference; meanwhile, after starting the near field communication, the two capacitive touch screens can accurately distinguish whether a change in the electrostatic field is caused by conductors becoming near, or by the terminal communicating with it, wherein the conductors are hand, and so on. Therefore, the reliability while the data transmission is started is improved and the user experience is optimized.
