1. A display device comprising:
a display panel including first and second pixels respectively connected to first and second sensing lines;
a sensing driver including a single sensing channel shared by the first and the second sensing lines; and
a controller configured to control the display panel and the sensing driver, wherein the controller is further configured to:
in a first time period, electrically disconnect the shared single sensing channel from the first and the second sensing lines and receive sensing voltages on respective ones of the first and the second sensing lines, the sensing voltages indicative of electrical characteristics of corresponding ones of the first and the second pixels; and
in a second time period, selectively record the sensing voltages on the first and the second sensing lines in the shared single sensing channel, the sensing voltages selectively recorded by time-sharing the shared single sensing channel with the first and second sensing lines.
