Patent ID: 7786959

Claim:
A display apparatus, comprising: a plurality of pixels, provided in a matrix manner, each of the pixels including a current driving type display element; selection lines for supplying a selection signal for selecting the pixels; and data lines for supplying data to selected pixels, each of the pixels including: a first transistor for controlling a current; a second transistor, provided in series with the first transistor and the display element, for supplying or stopping supplying of a current to the display element; a current setting circuit for setting an output current of the first transistor; and a driving circuit for turning ON or OFF of the second transistor so as to carry out a time-division gradation driving, the current setting circuit (i) setting the output current of the first transistor during one of a plurality of sub-frames, constituting a single frame, in which non-emitting data is always provided to the second transistor and the second transistor is turned from an ON state to an OFF state so that a gate voltage of the first transistor is changed to determine a threshold potential of the first transistor, and (ii) maintaining setting of the output current of the first transistor in remaining sub-frames of the single frame, when the time-division gradation driving is carried out.
