Abstract: A display device includes a display panel that includes a plurality of pixels, a data driver configured to provide a data voltage to the plurality of pixels, a scan driver configured to provide a first scan signal and a second scan signal to the plurality of pixels, and a controller configured to control the data driver and the scan driver. The display panel is driven at a driving frequency that is variable within a driving frequency range. The scan driver provides the first scan signal to the plurality of pixels at the driving frequency, and provides the second scan signal to the plurality of pixels at a second driving frequency that is equal to or higher than the driving frequency.

Abstract: A display device includes a display panel and a display panel driver. The display panel driver includes an over-driver which selects an over-driving data from an over-driving pattern which moves to a predetermined direction, generates a reference line based on a first polynomial expression generated based on the over-driving data, and generates an over-driving data lookup table by moving the reference line, a data driver which outputs a data signal generated based on the over-driving data lookup table to the data line of the display panel, and a gate driver which outputs a gate signal to the gate line of the display panel.
