Abstract:
1. A method for communication through touch screens comprising: providing a first touch screen and a second touch screen, wherein the first touch screen and the second touch screen both have a plurality of first conductive strips and a plurality of second conductive strips; 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 different ground potentials, 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, wherein the plurality of first conductive strips that will be provided with a driving signal and the plurality of second conductive strips that will provide capacitive signals as a result of the driving signal during the detecting mode, wherein during the communication mode, at least one of the first conductive strips and at least one of the second conductive strips are simultaneously provided with the driving signal, and another of the first conductive strips is provided with the ground signal.
