Claim:
An apparatus comprising: a pixel array in which pixel circuits are arranged in a matrix, each pixel circuit having (a) a light emitting device, (b) a drive transistor that applies a current in response to a gate-source voltage to the light emitting device, (c) a retention capacity that provides an input potential to the drive transistor and holds the input potential dependent on a threshold voltage of the drive transistor and an input video signal voltage, and (d) a sampling transistor that inputs a signal line voltage to the retention capacity; a signal selector that supplies threshold correction reference voltages and the video signal voltages as the signal line voltages to respective signal lines arranged in columns on the pixel array; a drive control scanner that provides power control pulses to respective power supply control lines arranged in rows on the pixel array and applies drive voltages to the drive transistors of the pixel circuits; and a write scanner that provides scan pulses to respective write control lines arranged in rows on the pixel array to control the sampling transistors of the pixel circuits and executes input of the threshold correction reference voltages and the video signal voltages to the respective pixel circuits, and brings the sampling transistors into conduction by the scan pulses at plural times when the signal line voltages are the threshold correction reference voltages in order to execute plural threshold corrections in non-emission periods of one light emission cycles of the respective pixels circuits, wherein, pre-bootstrap that raises the input potential is executed in a predetermined period before start of the first threshold correction in the plural threshold corrections, the predetermined period starts when the drive control scanner applies the drive voltage by way of the power control pulse and ends when the write scanner brings the sampling transistor into conduction by way of the scan pulse for the first threshold correction, and the predetermined period is shorter than half of a horizontal period of the signal line voltage and shorter than a period for executing the first threshold correction in the plural threshold corrections.
