Abstract
A display device can include a display panel having a pixel comprising a light emitting element configured to emit light and connected to a data line and a sensing line, and a display driver configured to receive a sensing signal from the sensing line at a first RT interval, a second RT interval, and an OFF-RS interval. The display driver can include a first switching element configured to be turned on based on a first switching signal at the first RT interval and electrically connect a reference voltage line to the sensing line, a second switching element configured to be turned on based on second switching signal at the OFF-RS interval and electrically connect a low potential line to the sensing line, and a third switching element configured to be turned on based on a third switching signal at the second RT interval.
