Abstract
A panel driving device includes a voltage generator and a data driver. The voltage generator generates a compensation voltage set and a gamma voltage set and selectively outputs the compensation voltage set or the gamma voltage set. The data driver outputs a reference voltage based on the compensation voltage set and outputs pixel data voltage based on the gamma voltage set.
