1. A power off method of a display device that includes a display panel having a plurality of pixel circuits arranged in a matrix, each of the plurality of pixel circuits including: a light emitting element that emits light with luminance corresponding to an amount of current supplied; a drive transistor that supplies the current to the light emitting element; and a capacitance element that is connected to a gate of the drive transistor and holds a voltage representing the luminance, the power off method of a display device comprising:
detecting a power off operation on the display device; setting, when the power off operation is detected, a voltage for suppressing electrical stress on the drive transistor, in the capacitance element in each of the plurality of pixel circuits; and stopping power supply to the display panel immediately after the voltage is set, wherein in the setting, a voltage equivalent to a threshold voltage of the drive transistor is set in the capacitance element in each of the plurality of pixel circuits. |
