Abstract

A touch electrode structure for defining position units includes electrodes electrically insulated from each other, in which each of the electrodes includes sub-electrodes electrically insulated from each other. Each of the sub-electrodes include sub-electrode units electrically connected to each other, in which each of the position unit is defined by the two sub-electrode units respectively belonging to the different sub-electrodes. The sub-electrode units in one of the position units of each of the electrodes have a combination corresponding to the sub-electrodes arranged therein, and each of the combinations is different from the other combinations in the each of the electrodes.
