Abstract
A display device including a display panel includes a sub-pixel connected to a data line and a reference line, and a data driver including a panel driving circuit and a panel sensing circuit, wherein during a first sensing operation of a ADC of the panel sensing circuit, the panel sensing circuit supplies a first reference voltage to the display panel through the reference line and converts a voltage that is sensed through the reference line in into a digital signal using the analog-to-digital converter, and during a second sensing operation of an element included in the sub-pixel, the panel sensing control circuit supplies a second reference voltage to the display panel through the reference line and the panel driving circuit supplies the data voltage to the display panel through the data lineoffset correction.
