Touch panel device and method for sensing a touched position |
摘要 |
Sensors are arranged in matrix form on a touch panel device. The touch panel device is provided with a P/S conversion circuit having the X-coordinate scan range change function and a P/S conversion circuit having the Y-coordinate scan range change function according to the similar configuration. When a touch is sensed, a scan range is limited around the touched position. This makes it possible to increase a speed of detecting an X coordinate signal and a Y coordinate signal without accelerating a scan shift clock.
