A display device comprises pixels arranged in a display area of a display panel, and a display driver determining whether image data indicates still image characteristics or moving image characteristics and controlling a supply timing of data voltages and pixel driving control signals supplied to the pixels based on the determination result, wherein the display driver selectively adjusts a driving frequency for driving the pixels and a level of a high-potential voltage supplied to the pixels based on as result of grayscale analysis of the image data.

Display device

A display device and a method of driving the same are provided. The method of driving the display includes a display area to display an image. The method includes performing a first first pixel shift driving by shifting an image by a first range in the display area without loss of image information due to enlargement or reduction of the image, checking whether a change of a block grayscale value is greater than or equal to a threshold in an interest area in the display area, and performing second pixel shift driving by shifting an image having the loss of image information.

Display device and method of driving the same

A display device includes a display panel including a first data line, a second data line, and a pixel, the pixel including a first sub-pixel coupled to the first data line, and a second sub-pixel coupled to the second data line, a light stress compensator configured to generate a first data voltage control signal for the first sub-pixel based on a second data value of input image data for the second sub-pixel, in response to a first data value of input image data for the first sub-pixel being equal to or less than a first reference value, and a data driver configured to generate a first data signal based on the first data value for the first sub-pixel, to provide a first data voltage to the first data line, and to vary the first data voltage based on the first data voltage control signal.

A display device is disclosed that includes pixels, a memory, and a degradation compensator. The pixels include light emitting elements. The memory is operable to store degradation information including degradation degrees of the light emitting elements. The degradation compensator is operable to receive the degradation information and generate output grayscales by changing each of input grayscales of the pixels in proportion to each of the degradation degrees. The degradation compensator includes a degradation information changer for changing the degradation information by decreasing a degradation degree having a variation greater than a threshold value among variations of the degradation degrees.

A display device includes a shift controller which generates an output image by shifting an input image within a shift range; and pixels which displays the output image. The shift controller sets the shift range to a first range when the input image is a moving image, and sets the shift range to a second range smaller than the first range when the input image is a still image.

Display device and driving method thereof

An afterimage compensator and a display device having the same are disclosed, and the afterimage compensator includes an image analyzer configured to determine an amount of image variation based on a change of image data, and an image shifter configured to adjust a shift interval, which is an interval between time points at which an image is shifted, according to the amount of image variation.
