Data Driver and Driving Method of Organic Light Emitting Display Device Using the Same |
摘要 |
A data driver capable of generating data signals with desired voltage values. The data driver includes a first digital-analog converter including a plurality of first switches, the first digital-analog converter selecting two reference voltages from among a plurality of reference voltages by turning on two of the first switches corresponding to high level bits of data; and a second digital-analog converter for dividing the two reference voltages into a plurality of voltages and for supplying any one of the two reference voltages and the divided voltages corresponding to low level bits of the data as a data signal to an output terminal, wherein the second digital-analog converter includes a transistor turned on by a bias voltage to compensate for a turn-on resistance of the two of the first switches.
