Abstract: A display device may include a display panel including first and second pixels respectively connected to first and second sensing lines, a sensing driver including a sensing channel shared by the first and the second sensing lines, and a controller configured to control the display panel and the sensing driver. The controller may be configured to, in a first time period, electrically disconnect the sensing channel from the first and the second sensing lines, and reflect electrical characteristics of the first and the second pixels in the first and the second sensing lines, respectively, as sensing voltages, and in a second time period, record the sensing voltages reflected in the first and the second sensing lines in the sensing channel by time-sharing.
