Abstract: A display apparatus includes 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 for a luminance difference between the first polarity and a second polarity opposite to the first polarity of a 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 for an RC delay based on a pixel position corresponding to the input data.

Abstract: A driving unit of display panel includes a data driving part, a timing controlling part and a gate driving part. The data driving part is configured to receive reference image data and includes a first data driving circuit part having a first channel outputting a first reference data signal based on the reference image data and a k-th channel outputting a k-th reference data signal based on the reference image data. The timing controlling part is configured to detect a time difference between the first reference data signal and the k-th reference data signal. The gate driving part is configured to output a gate signal to each of gate lines. By delaying data signals based on the gate signal delay caused by long line load and RC delay, the present invention may improve display quality of a display device.
