Patent ID: 8269755

Claim:
A display apparatus comprising: a plurality of pixel circuits; drive scan lines which supply the same power supply potential to each group of the plurality of pixel circuits, the group having a plurality of pixel circuits for a plurality of successive rows; and a power supply circuit which, during an extinction period of a current scanning field for extinguishing light-emitting devices in pixel circuits belonging to each group, supplies a high-level power supply potential to the respective pixel circuits belonging to the group related to the extinction period so as to switch the power supply potential to the high-level power supply potential higher than the power supply potential, wherein, (1) each of the plurality of pixel circuits includes (a) a storage capacitor which retains a voltage corresponding to a video signal, (b) a drive transistor which supplies a current based on the voltage retained in the storage capacitor to a corresponding light-emitting device by receiving the power supply potential supplied to the corresponding drive scan line, (c) a light-emitting device which emits light in accordance with the current supplied from the drive transistor, and (d) a write transistor which, during the extinction period, gives an extinction potential for extinguishing the light-emitting device to a gate terminal of the drive transistor, and then writes the voltage corresponding to the video signal to the storage capacitor, (2) the extinction period occurs after a light emission period of a previous field and before a threshold correction preparation period of the current scanning field, and (3) during the correction preparation period the power supply voltage is at the power supply potential.
