Abstract: A display panel driver includes a timing controller and a data driver. The timing controller generates a data signal based on an input image data. The data driver receives the data signal, converts the data signal into a data voltage and outputs the data voltage to a display panel. The data signal includes positive data and negative data. The data driver includes a data skew compensating circuit which samples the positive data using the negative data and compensates a skew of the data signal.

Abstract: A display device includes a display panel which displays an image, a current compensator and a panel driver. The current compensator calculates a load based on input image data and compensates the input image data to output compensation image data having a target current corresponding to the load. The panel driver drives the display panel based on the compensation image data. The current compensator calculates the load for the input image data based on a combination of load weights calculated by different variables.
