Claim 18:
19. A method of performing an over-current protecting operation of a display device, the method comprising:
receiving an input power supply voltage when the display device is powered on;
generating and outputting an initialization voltage for initializing an initialization target node within a pixel circuit based on the input power supply voltage;
performing a first over-current protecting operation of detecting whether an initialization voltage current caused by the initialization voltage is an over-current in a power-on monitoring period that is set between a first time point at which the initialization voltage is output and a second time point at which a scan clock signal for generating a scan signal that is to be applied to the pixel circuit is output; and
shutting down the display device when the initialization voltage current is determined as the over-current in the power-on monitoring period.
