Abstract: In a method of generating correction data for a display device, measured tristimulus data at a maximum gray level are obtained, measured luminance and color coordinate profiles are obtained based on the measured tristimulus data, a target color coordinate profile is determined based on the measured color coordinate profile, measured red, green and blue maximum luminances of each pixel are obtained, a maximum target luminance of the each pixel is determined such that red, green and blue luminances of the each pixel become lower than or equal to the measured red, green and blue maximum luminances, respectively, a final target luminance profile is determined based on the measured luminance profile and the maximum target luminance of the each pixel, and correction data may be generated and stored in the display device based on the final target luminance profile and the target color coordinate profile.

Abstract: A display apparatus includes a display panel, a driving controller, a gate driver and a data driver. The display panel includes a plurality of gate lines, a plurality of data lines and a plurality of pixels. The pixels are connected to the gate lines and the data lines. The driving controller determines a compensating value of a present data signal based on a previous data signal and the present data signal which are applied to a same data line of the data lines. The gate driver outputs a gate signal to the gate line. The data driver generates a data voltage based on the present data signal and the compensating value and outputs the data voltage to the same data line.
