Publication number: 20240153453Abstract: A display device includes a display panel which includes a pixel including a driving transistor and a light-emitting element, and a sensing line connected to the pixel. A sensing driver senses a first sensing signal corresponding to mobility of the driving transistor through the sensing line, and processes the first sensing signal to output first sensing data. A driving controller receives the first sensing data from the sensing driver, generates mobility compensation data and kickback compensation data based on the first sensing data, and converts image data into compensation image data by the mobility compensation data and the kickback compensation data. A data driver converts the compensation image data into a data signal and provides the data signal to the pixel.Type: ApplicationFiled: August 26, 2023Publication date: May 9, 2024Inventors: KANG-MIN KIM, DONGIN KIM, BYOUNGCHEL KIM, JAHUN KOO, YEONG WON KIM, BONGIM PARK, GYUSU LEE, HYE RYEON JO
