Abstract: A display apparatus includes a display panel, a gate driver, a gray scale compensator, and a date driver. The gate driver sequentially applies gate data to the gate lines. The gray scale compensator compares the primitive gray scale data of the n-th frame with the primitive gray scale data of the (n?1)-th frame to output a compensated gray scale data of a n-th frame, when a primitive gray scale data of a (n?1)-th frame is lower than a gray scale data of a first gray scale and a primitive gray scale data of the n-th frame is higher than a gray scale data of a second gray scale. The date driver converts the compensated gray scale data into a date voltage corresponding to the compensated gray scale data and applies the data voltage to the date line. Therefore, response time of the liquid crystal molecules may be reduced.

Abstract: A display device including a liquid crystal display unit and a controller displays an image using a liquid crystal. The controller extracts a compensation data from a gray compensation look-up table (LUT) corresponding to a temperature interval including a peripheral temperature of the display device to output the compensation data to the liquid crystal display unit as a compensated gray data. When the gray compensation LUT does not exist, the controller extracts the compensation data from the gray compensation LUT corresponding to the temperature interval approximating the peripheral temperature to generate the compensated gray data. The gray compensation LUT as a default and a calculated gray compensation LUT may be used to provide the compensated gray data optimized for the response speed of the liquid crystal according to variance in temperature, while reducing a memory capacity of a ROM and a RAM inside the timing controller and an external EEPROM.
