A display device, comprising:
- a display panel in which a pixel circuit including a light-emitting diode and a driving transistor connected to the light-emitting diode is disposed;
- a power circuit configured to generate a high-potential power voltage and supply the high-potential power voltage to the pixel circuit;
- and
- a sequence control circuit electrically connected to the power circuit, and configured to generate a power control signal for controlling whether or not to operate the power circuit and supply the power control signal to the power circuit,
- wherein the power circuit is configured to be turned on in a first state and be turned off in a second state according to a voltage value of the power control signal, and
- wherein the display device is provided, from an external system, with a high-potential basic voltage involved in generating the high-potential power voltage and an operating voltage as a power source for operating the power circuit.
