Claim:
1. A display apparatus comprising: a display panel comprising a gate line, a data line crossing the gate line and a sub pixel which is electrically connected to the gate line and the data line; a first interpolator configured to generate first correction data for a first polarity corresponding to an input data using a first look up table which stores correction data for the first polarity compensating a luminance difference which is due to liquid crystal response time later than change time of a data voltage and which is between the first polarity and a second polarity opposite to the first polarity of the data voltage for the sub pixel; a first delay compensator configured to apply a correction value to the first correction data for the first polarity and generate second correction data for the first polarity, the correction value compensating an RC delay based on a pixel position corresponding to the input data; an output selector configured to selectively output the second correction data for the first polarity based on polarity mapping data of K-bit (K is a natural number), the polarity mapping data mapped to polarities of K sub pixels according to an inversion mode; and a data driver circuit configured to convert the second correction data for the first polarity to replace the data voltage and output the converted second correction data to the sub pixel.
