Abstract
A data driver includes a plurality of amplifiers configured to output a plurality of data voltages to a plurality of data lines. The amplifiers are configured to output the data voltages to the corresponding data lines in a writing mode. Only one of the plurality of amplifiers is configured to output a sensing data voltage to the plurality of data lines in a sensing mode.
