Abstract: A display device includes a display panel, a driving controller, a gate driver and a data driver. The display panel includes pixels. The driving controller determines a kickback compensation value of a gate signal according to at least one of a grayscale value of an input image data and a distance from a scan start point of the gate signal. The gate driver is configured to generate the gate signal based on the kickback compensation value and to output the gate signal to the display panel. The data driver is configured to output a data voltage to the display panel.

Abstract: A display device includes: a display panel including pixels, a power voltage generator for applying a power current to the display panel in a driving period; and a current sensor including a sensing resistor disposed between the display panel and the power voltage generator; a sensing current determiner for determining a sensing current; and a constant current generator for generating a constant current to the sensing resistor in a test period. The sensing current determiner determines a test sensing current based on a test sensing voltage applied to opposite electrodes of the sensing resistor in the test period and an initial sensing resistance, determines a first sensing resistance based on the test sensing current, the initial sensing resistance, and the constant current, and determines the sensing current based on a driving sensing voltage applied to the electrodes of the sensing resistor in the driving period and the first sensing resistance.

Abstract: A display device includes a display panel including a plurality of pixels, a first driving circuit configured to operate to display an image through the plurality of pixels, and a shutter panel including a plurality of shutter pixels and configured to be periodically refreshed. The first driving circuit is operated to display a second image corresponding to a second image signal through the display panel when a difference in brightness between a first image signal of a present frame and the second image signal of a previous frame is greater than a predetermined level and to display a first image corresponding to the first image signal through the display panel when the shutter panel is refreshed.
