Abstract
A display device includes a display panel including scan lines, data lines, and a plurality of pixels coupled to the scan lines and the data lines, a voltage generator configured to generate an on-voltage and an off-voltage, a scan controller configured to generate a scan start signal based on the on-voltage, the off-voltage, and a vertical start signal, and a scan driver configured to generate a scan signal based on the scan start signal and to provide the scan signal to a scan line of the scan lines. The scan controller is configured to detect a voltage level of the scan start signal and to output a shutdown signal based on the voltage level of the scan start signal during an over current detecting period.
