ABSTRACT:
A data driver for an OLED display has a resistor string, digital-to-analog converters and converting transistors. The resistor string provides a set of gamma voltages. Each of the digital-to-analog converters converts an input word into an output voltage selected from the gamma voltages. Each of the converting transistors conducts a driving current and having a gate-to-source voltage determined by the output voltage from one of the digital-to-analog converters. A method of data driving for an OLED display is also disclosed.
