Abstract: The present disclosure provides a display device. The display device may comprise a display panel including a plurality of pixels, a reference current source providing a reference current, and a source drive IC including sensing units for sampling a signal input from the pixel through a sensing line and an ADC connected to the sensing units and obtaining sensing data related to a driving of the pixel. The source drive IC may further comprise a switch array connecting the sensing lines and the sensing units, and the switch array in each sensing unit may comprise a first switch for connecting a corresponding sensing unit to a first sensing line corresponding to the corresponding sensing unit and a second switch for connecting the corresponding sensing unit to a second sensing line adjacent and previous to the first sensing line or the reference current source.
