Abstract: A display device includes: a pixel connected to each of a first scan line, a second scan line, and a data line; a scan driver supplying a first scan signal to the first scan line and a second scan signal to the second scan line; a controller dividing one frame period into an active period and a blank period and generating a count signal in which a time duration of the blank period is counted and a power control signal; a data driver supplying a data signal to the data line; and a power supply controlling a source driving voltage supplied to the data driver according to a duration of the blank period based on the power control signal. When the count signal reaches a reference value, the controller supplies a start signal for output of the first scan signal to the scan driver.

Abstract: A display device capable of setting an optimal output enable value according to a color pattern and a method for driving the display device. A timing controller is configured to receive an image signal from an external source, identify a color pattern and set an output enable value corresponding to the identified color pattern. A scan driver is configured to receive the output enable value and generate a first scan signal having a first turn-on signal and a second scan signal adjacent to the first scan signal and having a second turn-on signal. The scan driver may adjust an interval between the first turn-on signal and the second turn-on signal based on the output enable value.

Abstract: A display device and method is provided that permits selection of a first lookup table or a second lookup table to operate the data driver at respectively different temperatures to prevent heat from damaging the display device. The display device includes a detector which detects the number of toggles in which the amount of change in gray values of successive pixels driven by the same data line in one frame is equal to or greater than a reference gray change amount. A comparator compares the number of toggles detected by the detector with a reference number of toggles, and a lookup table selector which selects any one of a first lookup table and a second lookup table based on the comparison result of the comparator and provides the selected first lookup table or second lookup table to a data driver.
