DISPLAY APPARATUS

摘要

PURPOSE: A display device is provided to prevent the degradation of the image due to the abnormal gamma voltage. CONSTITUTION: A data receiver(200) receives digital reference data and a reference data clock as the reference of a gamma voltage. A plurality of registers(210,211) store the reference data received by the data receiver. A digital-analog converter(220,221) converts the reference data into a plurality of first and second gamma voltages and outputs the converted result. A voltage set unit(240) receives a plurality of sub reference voltages and outputs a plurality of third gamma voltages. The voltage set unit selectively outputs the sub reference voltage or the voltage with a specific level.
