DATA DRIVER AND METHOD OF DRIVING THE SAME

摘要

A data driver includes buffers, bias circuits, and a bias signal generator. The buffers respectively output data voltages corresponding to pixel image data. The bias circuits generate bias currents independent of each other and apply the bias currents to respective ones of the buffers. The bias signal generator generates a plurality of bias signals. Each of the bias circuits include a selector and a bias current generator. The selector selects one bias signal among the bias signals based on corresponding pixel image data and outputs the selected bias signal as a final bias signal. The bias current generator generates a corresponding bias current among the bias currents based on the final bias signal.

1. A data driver, comprising:
a plurality of buffers to respectively output data voltages corresponding to pixel image data; a plurality of bias circuits provided in one-to-one correspondence with the buffers, the bias circuits to generate bias currents independent of each other and to apply the bias currents to the buffers, respectively; and a bias signal generator to generate a plurality of bias signals, wherein each of the bias circuits include: a selector to select one bias signal among the bias signals based on corresponding pixel image data among the pixel image data and to output the selected bias signal as a final bias signal; and a bias current generator to generate a corresponding bias current among the bias currents based on the final bias signal.
