Method and terminal for data transmission between terminals

摘要

Disclosed is a method for data transmission between terminals and a terminal. The method is applied between a first terminal and a second terminal, with a first capacitive touch screen set on the first terminal and a second capacitive touch screen set on the second terminal, and the method includes: the first terminal transforms the information to be transferred into binary data, then correspondingly applies a voltage to the electrodes involved in data transmission on the first capacitive touch screen and forms corresponding electric field distribution information; when the first capacitive touch screen contacts with the second capacitive touch screen, the second terminal decodes the information to be transferred according to the detected electric field distribution information currently on the first capacitive touch screen.

1. A method for data transmission between terminals, applied between a first terminal and a second terminal, said first terminal equipped with a first capacitive touch screen and said second terminal equipped with a second capacitive touch screen, comprising:
said first terminal transforming information to be transferred into binary data, and accordingly applying a voltage to electrodes involved in data transmission on said first capacitive touch screen, and forming corresponding electric field distribution information; when said first capacitive touch screen contacts with said second capacitive touch screen, said second terminal decoding said information to be transferred according to detected electric field distribution information currently on said first capacitive touch screen; wherein before said first terminal transforms said information to be transferred into binary data, the method further comprises: said first terminal informing said second terminal of information, comprising: an electric field range, a distance between electrodes, a number of row electrodes, a number of column electrodes, and which electrodes are involved in data transmission;
wherein,said first terminal applies a voltage to edge row electrodes and edge column electrodes on said first capacitive touch screen, to inform said second terminal of the electric field range on said first terminal;said first terminal applies a voltage to all of said row electrodes and all of said column electrodes on said first capacitive touch screen, to inform said second terminal of the number of row electrodes and the number of column electrodes and a distance between electrodes on said first terminal;said first terminal applies a voltage to row electrodes or column electrodes involved in said data transmission, to inform said second terminal of which electrodes are involved in said data transmission on said first capacitive touch screen; andsaid first terminal applies a voltage to an utmost edge electrode involved in said data transmission, to inform said second terminal of a position of an electrode in which a first bit of said binary data is located.
