Patent ID: 8581807

Claim:
A display device comprising: a pixel array section having pixel circuits arranged in a form of a matrix, a given one of said pixel circuits including: a driving transistor for generating a driving current, an electrooptic element connected to an output terminal of said driving transistor, a storage capacitor for retaining information corresponding to a signal amplitude of a video signal, and a sampling transistor for writing the information corresponding to said signal amplitude to said storage capacitor; a vertical scanning section configured to generate vertical scanning pulses for vertical scanning of said pixel circuits; and a horizontal scanning section configured to supply the video signal to said pixel circuits so as to coincide with said vertical scanning in said vertical scanning section; wherein said given one of said pixel circuits is configured for a driving signal constancy function for holding said driving current constant; wherein said given one of said pixel circuits is configured for a threshold value correcting function that makes said storage capacitor retain a voltage corresponding to a threshold voltage of said driving transistor; wherein said vertical scanning section and said horizontal scanning section are configured to cause said given one of said pixel circuits to realize said threshold value correcting function through a threshold value correcting process comprising making said sampling transistor conduct while current is flowing through said driving transistor and a reference potential is supplied to an input terminal of said sampling transistor, and wherein said vertical scanning section and said horizontal scanning section are configured to cause said given one of said pixel circuits to: perform said threshold value correcting process during a plurality of horizontal scanning periods within a given non-emission period while the state of the current flowing through said driving transistor is maintained, and perform a threshold value correcting divided process within at least one of said plurality of horizontal periods, said threshold value correcting divided process comprising, within a single horizontal period: performing said threshold value correcting process; thereafter, placing said sampling transistor in a non-conducting state while said reference potential is supplied to the input terminal of said sampling transistor; and thereafter, performing said threshold value correcting process again.
