Claim:
1. A non-display signal encoding method cooperating with a matrix substrate including a plurality of electrodes crossing each other and transmitting a plurality of display signals and a plurality of non-display signals, the non-display signal encoding method comprising steps of: transmitting the non-display signals by at least one of the electrodes during a first time; and receiving by coupling at least a part of the non-display signals by at least an external object, wherein the non-display signals have a first state, a second state, and a third state or their any combination, and the first state, second state and third state are different from one another, wherein electrodes of the matrix substrate include a plurality of first electrodes arranged along a first direction and a plurality of second electrodes arranged along a second direction, and at least one of the first electrodes or second electrodes transmits the non-display signals, wherein the first electrodes or second electrodes include a first electrode group and a second electrode group, and each of the electrode groups includes at least an electrode, wherein during the first time, the first electrode group transmits the non-display signals of the first state or third state, and the second electrode group transmits the non-display signals of the second state, wherein during a time other than the first time, the first electrode group transmits the non-display signals of state different from the state that the first electrode group transmits during the first time, wherein information carried by the non-display signals is encoded by the first state and the third state, and the second state is for separating the first state and third state.
