Abstract
A liquid crystal display includes a pixel, a memory configured to store a plurality of look-up tables, an image signal modification unit configured to obtain a modified look-up table based on a first look-up table and a second look-up table among the plurality of look-up tables and modify an input image signal based on the modified look-up table to generate a modified image signal, and a data driver configured to convert the modified image signal generated by the image signal modification unit into a data voltage and to supply the data voltage to the pixel. The liquid crystal display includes a plurality of regions. The liquid crystal display is configured to maintain temperature information of the plurality of regions, and the image signal modification unit is configured to modify the input image signal based on the temperature information.
