Publication number: 20170221958Abstract: With an image sensor in which the amplifier circuit is disposed at each pixel, there is such an issue that the threshold voltage of the transistor fluctuates so that the signal voltage fluctuates because a voltage is continuously applied between the source and the gate of the transistor at all times when using the amorphous thin film semiconductor as the transistor that constitutes an amplifier circuit. The gate-source potential of the TFT that constitutes the amplifier circuit is controlled so that the gate terminal voltage becomes smaller than the source terminal voltage in an integrating period where the pixels accumulate the signals, and controlled so that the gate terminal voltage becomes larger than the source terminal voltage in a readout period where the pixels output the signals.Type: ApplicationFiled: April 18, 2017Publication date: August 3, 2017Inventor: Hiroyuki SEKINE
