Display device and driving method thereof

摘要

A display device includes a memory which stores gamma data for gamma curves including a first gamma curve and a second gamma curve; a gray voltage generator which generates gray voltages based on the gamma data; a data driver which receives an input image signal from a signal controller and converts the input image signal into a data voltage using the gray voltages; and a display panel including pixels which receives the data voltage and may display an image, where the pixel displays images corresponding to the input image signal during one frame set, one frame set includes consecutive frames, the images displayed by a pixel includes first and second images displayed based on the first and second gamma curves, respectively, a luminance of the first image is not less than a luminance of the second image, and the second image is displayed in two consecutive frames.

1. A display device comprising:
a memory which stores gamma data corresponding to a plurality of gamma curves including a first gamma curve and a second gamma curve that are different from each other; a gray voltage generator which generates a plurality of gray voltages based on the gamma data; a signal controller which receives input image signals; a data driver which receives the input image signals from the signal controller and converts the input image signal into data voltages using the gray voltages; and a display panel comprising a plurality of pixels which receive the data voltages and displays images, wherein a pixel of the pixels displays a plurality of images corresponding to a first input image signal during a first frame set comprising a plurality of consecutive frames, and displays a plurality of images corresponding to a second input image signal during a second flame set directly following the first frame set and comprising a plurality of consecutive frames, during each of the first frame set and the second frame set, the images displayed by the pixel includes a first image based on the first gamma curve and a second image based on the second gamma curve, a luminance of the first image is equal to or greater than a luminance of the second image, the second image is displayed by the pixel in two consecutive frames, and a temporal gamma sequence of the images displayed by the pixel in the first frame set is opposite to a temporal gamma sequence of the images displayed by the pixel in the second frame set.
