Abstract: A liquid crystal display device includes: a display panel including a plurality of pixels for displaying an image; a temperature sensor for sensing a temperature; an image data corrector for calculating correction parameters based on a grayscale change, calculating temperature parameters based on preset reference temperatures and the correction parameters, and correcting current image data to provide corrected image data based on the correction parameters and the temperature parameters; and a data driver for converting the corrected current image data into a data voltage and supplying the data voltage to the display panel. At least one of the correction parameters has a value that varies linearly with the sensed temperature and is based in part on the temperature parameters.

Abstract: A display device and a driving method is disclosed. The driving method includes receiving an image signal for one frame for one pixel, converting the image signal into at least two data voltages according to at least two gamma curves, applying a first gate signal and a second gate signal to a plurality of gate lines respectively connected to a plurality of subpixels included in one pixel during the frame. The method further includes applying the at least two data voltages to the plurality of subpixels during the frame. A gamma curve for the data voltage applied to one subpixel among the plurality of subpixels includes the at least two different gamma curves and is changed with a period of a first time.
