Apparatus and method of identifying touch area |
摘要 |
Methods and apparatus are provided for identifying coordinates of a touch area on a touch screen panel based on a capacitive scheme. The touch screen panel has a first electrode layer having first electrode lines aligned in a first direction and a second electrode layer having second electrode lines aligned in a second direction. A signal generation unit generates a spread spectrum signal and supplies the spread spectrum signal to the first electrode layer. A signal restoration unit processes a band restoration for a signal input from the second electrode layer. A touch area coordinate identification unit identifies the coordinates of the touch area on the touch screen panel from a signal input from the signal restoration unit. |
