DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

A display device includes: a plurality of pixels comprising normal pixels and sample pixels; a plurality of sensing units which sense luminance of the sample pixels and generate sensing signals based on the sensed luminance; a gray voltage generator which generates a plurality of reference gray voltages having values depending on the sensing signals; and a data driver which generates normal data voltages for the normal pixels and sample data voltages for the sample pixels.
