Method of generating correction data for display device, and display device storing correction data

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.
