Abstract

A display device that may compensate for characteristic deviations among pixels and impact picture quality is provided. The display device includes a plurality of pixels, a plurality of sensing lines connected to the pixels, a sensing circuit configured to extract characteristic information of the pixels through the sensing lines. The sensing circuit includes a plurality of analog-to-digital converters (ADC) to convert the characteristic information into digital sensing data and to output the digital sensing data. A compensating circuit is configured to compare output values of the plurality of ADCs, to set a correction value, and to convert first data into second data based on the sensing data and the correction value. A data driver is configured to generate data signals corresponding to the second data and to output the data signals to the pixels.
