Abstract
A display apparatus includes: a gamma reference voltage generator, a digital-to-analog converter, an amplifier and a bias voltage applier. The gamma reference voltage generator is configured to generate a gamma reference voltage. The digital-to-analog converter is configured to convert a data signal to a data voltage based on the gamma reference voltage. The amplifier is configured to receive the data voltage from the digital-to-analog converter and to output the data voltage to a data line. The bias voltage applier is configured to output a first bias voltage to the gamma reference voltage generator and to output a second bias voltage to the amplifier. The bias voltage applier is turned off while input image data have a black image.
