Abstract:
A drive circuit classifies frame periods as a drive period and a pause period, and applies a selection voltage to scanning lines in turn and applies voltages according to a video signal (a measurement voltage in the case of measurement targets) to data lines in turn during the drive period. During the pause period, the drive circuit applies the selection voltage to one scanning line corresponding to measurement target pixel circuits, and a measurement circuit measures drive currents outputted to the data lines from the measurement target pixel circuits. The drive circuit may set a write period and a measurement period in the pause period. During the write period, the drive circuit may apply the measurement voltage to the data lines. During the measurement period, the measurement circuit may measure drive currents outputted to the data lines from the measurement target pixel circuits.
