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.

摘要： During a first period of a set period, a reset switch element of each pixel is turned on to converge a voltage at a control electrode of a TFT to a predetermined voltage, and a step signal having a first voltage level is supplied from a step signal generation circuit. During a second period of the set period, the reset switch element is turned off, and a step signal having a second voltage level is supplied from the step signal generation circuit, whereby a voltage exceeding a second power supply voltage or a voltage exceeding a voltage range supplied from a signal driver section is input as a characteristic value set voltage to the control electrode. Accordingly, even when a relationship between a gate voltage and a drain current of the thin film transistor exhibits a hysteresis characteristic, uniform display can be achieved.
