First Claim
Patent Images
1. A method for communication through touch screens comprising:
- providing a first touch screen and a second touch screen;
individually determining whether there is an approach or a touch of an external conductive object during a detecting mode of the first and the second touch screens; and
performing capacitively coupled communications between the first and the second touch screens during a communication mode of the first and the second touch screens in order to exchange or communicate a message, wherein during communication, at least a portion of the first touch screen and at least a portion of the second touch screen are provided with a ground potential, respectively, and the portions of the first and the second touch screens being provided with the ground potentials are capacitively coupled with each other face-to-face, such that the ground potentials of the first and the second touch screens are made to be closer to each other.

Abstract
The invention discloses a system and method for communication through touch screens that uses a first touch screen and a second touch screen for communication to form a communication system. The first and the second touch screens have a detecting mode for detecting an approach or touch of an external conductive object. In addition, the first and the second touch screens have a communication mode in which capacitively coupled communications between the first and the second touch screens are performed in order to exchange or communicate a message.
