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.

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