Patent ID: 8456397

Claim:
A display apparatus for calibrating grayscale data of a current frame using the grayscale data of a previous frame and the current frame, comprising: a timing controller which calibrates the grayscale data of the current frame by changing the grayscale data of the current frame to first calibration data, second calibration data, and third calibration data using an overdrive method, a pre-tilt method, and an undershoot method and calculating the first calibration data, the second calibration data and the third calibration data, wherein the timing controller adds weighted values to the first calibration data, the second calibration data and the third calibration data and sums up the first calibration data, the second calibration data and the third calibration data to which weighted values are added to calibrate the grayscale data of the current frame; and a driving unit which drives a panel using the calibrated grayscale data of the current frame, wherein the first calibration data, the second calibration data and the third calibration data are determined based on one of a plurality of previously stored look-up tables, and wherein the first calibration data corresponds to the overdrive method, the second calibration data corresponds to the pre-tilt method, and the third calibration data corresponds to the undershoot method.
