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.

Abstract: A driving controller includes a first compensator and a second compensator. The first compensator is configured to generate first compensation data based on input image data. The second compensator is configured to generate second compensation data based on present frame data of the input image data, previous frame data of the input image data, present frame data of the first compensation data and previous frame data of the first compensation data.
