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.
