Abstract: A gamma voltage generator includes a resistor string, a gamma voltage provider, and a power supply string point. The resistor string provides a plurality of string voltages through a plurality of resistor string points. The resistor string is connected between a first gamma power supply voltage and a second gamma power supply voltage. The gamma voltage provider provides a plurality of gamma voltages based on the plurality of string voltages. A power supply string point to which the second gamma power supply voltage is applied is determined as the first gamma power supply voltage is changed. The power supply string point corresponds one of the resistor string points.

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.
