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.

摘要： In organic EL display apparatuses, when the reset operating time required for compensating variations in the OLED drive TFT voltage threshold is too short then fluctuations in the threshold voltage Vth cannot be corrected and an accurate gray scale is impossible. A precharge voltage is supplied from the precharge TFT switch prior to the reset TFT switch and the light TFT switch resetting the Vth of the OLED driver TFT, in order to apply a specified voltage value to the gate voltage of the OLED driver TFT prior to reset. The voltage potential on the gate of the OLED driver TFT prior to reset is therefore no longer an undetermined voltage potential so variations in the gate voltage after reset are suppressed and variations in the gray scale are suppressed.
