DISPLAY DEVICE

摘要

Provided is a display device which is provided with an optical detecting element in a pixel and capable of automatically correcting an optical sensor signal while the display device is being operated. A sensor row driver (5) is provided with first operation mode wherein an optical sensor signal corresponding to the light receiving quantity of the optical sensor is outputted to a signal processing circuit (8) by supplying an optical sensor in a pixel region (1) with a first pattern sensor driving signal; second operation mode wherein a first optical sensor signal level for correction equivalent to a case where the optical sensor detected a black level is obtained, by supplying a second pattern sensor driving signal; and third operation mode wherein a second optical sensor signal level for correction equivalent to a case where the optical sensor detected a white level is obtained, by supplying a third pattern sensor driving signal. The signal processing circuit (8) corrects the optical sensor signal in the first operation mode by using the first and the second optical sensor signal levels.
