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.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a backlight assembly. The display panel includes a plurality of display blocks. The gate driver outputs a gate signal to the display panel. The data driver outputs a data voltage to the display panel. The backlight assembly provides light to the display panel. Sequences of outputting the gate signals from the gate driver to the display blocks are different from each other in adjacent frames.

Abstract: A display device includes a signal controller and a data driving circuit. The data driving circuit includes a plurality of driving chips. At least one of the driving chips monitors a degree of distortion of a data signal. The at least one of the driving chips generates a feedback signal based on the monitored result to compensate for the distorted data signal.
