Patent ID: 8605066

Claim:
A display apparatus, comprising: a plurality of pixel circuits disposed in a display area in a matrix form and each including a light emitting element; a light emission driving section configured to selectively apply a video signal to the plurality of pixel circuits and to cause the plurality of pixel circuits to emit light of gradations corresponding to values of the video signal respectively applied thereto; a light detection driving section configured to control a light detection operation of at least one light detection unit, where the light detection unit is configured to perform the light detection operation, which includes: detecting light emitted from the light emitting element of at least one of the plurality of pixel circuits corresponding to the light detection unit, generating light detection information corresponding to an amount of light detected, and outputting a detection signal corresponding to the generated light detection information to a detection line; a correction information production section configured to receive the detection signal, generate correction information for correction of a value of the video signal based on the detection signal, and supply the generated correction information to the light emission driving section; and an initialization control section configured to perform an initialization operation comprising causing all nodes of the at least one light detection unit to have an equal potential during an initialization period, the initialization period occurring in a frame period in which the light detection operation is not being performed, where the nodes of the at least one light detection unit include all electrodes of each element included in the at least one light detection unit.
