Abstract:
A display apparatus includes the following components. A pixel array includes matrix-arranged pixel circuits each including at least a light emitting element, a drive transistor in which a drive voltage is applied between the drain and the source to supply a current corresponding to a signal value supplied between the gate and the source to the light emitting element, and a holding capacitor which is connected between the gate and the source of the drive transistor and which holds the input signal value. A mobility correction operating unit supplies the drive voltage to the transistor while the capacitor holds a correction signal value lower than the signal value to perform mobility correction for the transistor. A light emission operating unit allows the capacitor to hold the signal value and supplies the drive voltage to the transistor after correction to perform light emission at a luminance corresponding to the signal value.
