Abstract:
A display apparatus includes: a pixel array in which pixel circuits each having a light emitting device, a drive transistor, a sampling transistor, and a retention capacity; a signal selector that supplies threshold correction reference voltages and a video signal voltages as to signal lines arranged in columns on the pixel array; a drive control scanner that provides power supply pulses to power supply control lines arranged in rows on the pixel array and applies drive voltages to the drive transistors; and a write scanner that provides scan pulses to write control lines arranged in rows on the pixel array to control the sampling transistors and executes input of the threshold correction reference voltages and the video signal voltages to the 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 pixels circuits.
