Problems solved by technology

[0004] The current problem is that because the electric field detection method is used, if the size difference between the first capacitive touch screen and the second capacitive touch screen is large, it will cause a decrease in communication quality and cause data transmission to fail.

Abstract

The invention provides a near field communication system and terminals. The near field communication system comprises the first terminal and the second terminal, wherein the first terminal is provided with a first near field communication area; the second terminal is provided with a second near field communication area; the second near field communication area is provided with a first subunit and a second subunit; the first subunit and the second subunit are used for detecting the distance between the first near field communication area and the second near field communication area, and the second subunit is used for being in communication with the first near field communication area when the distance between the first near field communication area and the second near field communication area is smaller than or equal to preset distance; or the second subunit detects the distance between the first near field communication area and the second near field communication area, and the second subunit is in communication with the first near field communication area when the distance between the first near field communication area and the second near field communication area is smaller than or equal to the preset distance. By arrangement of the special communication areas, signal attenuation and external disturbance in data transmission are reduced, and communication quality is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a near-field communication system and a terminal. Background technique [0002] Near-field communication is a short-distance high-frequency wireless communication method. Terminals can perform non-contact point-to-point data transmission within a range of about ten centimeters through near-field communication. In a traditional capacitive touch screen terminal with a near field communication function, the near field communication module and the touch detection module are distributed on different integrated chips. The near-field communication module uses a dedicated antenna to realize data transmission with other terminals, and the touch detection module detects whether there is a trigger operation and the location of the trigger operation on the touch screen of the touch terminal through the driving electrodes and sensing electrodes on the touch sensor. Because two ...
