Abstract:
1. A method of driving a display apparatus, wherein the display apparatus includes a scanning circuit, a signal output circuit, a plurality of scanning lines which are connected to the scanning circuit and extend in a first direction, a plurality of data lines which are connected to the signal output circuit and extend in a second direction different from the first direction, display devices which are arranged in a two-dimensional matrix, and display device having a current-driven light-emitting portion and a drive circuit, and a power supply portion, the drive circuit including a write transistor, a drive transistor, and a capacitor portion, a first current terminal of the write transistor being connected to a corresponding data line and a gate electrode of the write transistor being connected to a corresponding scanning line, a first current terminal of the drive transistor being connected to the power supply portion, a second current terminal of the drive transistor being connected to an anode electrode of the light-emitting portion and being connected a first electrode of the capacitor portion at a second node, and a gate electrode of the drive transistor being connected to a second current terminal of the write transistor and being connected to a second electrode of the capacitor portion at a first node, the method comprising: performing write processing that includes applying an auxiliary video signal to the corresponding data line, then applying a video signal to the corresponding data line, the auxiliary video signal being distinct from the video signal and having a predetermined voltage that is distinct from a power supply potential, and in a state where a predetermined drive voltage is applied from the power supply portion to the first current terminal of the drive transistor, applying the predetermined voltage of the auxiliary video signal and a voltage of the video signal from the corresponding data line to the first node, through the write transistor while the write transistor is turned on in response to a scanning signal from the corresponding scanning line, the predetermined voltage of the auxiliary signal being set to reduce an amount of time required for the voltage of the video signal to be provided at the first node during the write processing.
