ABSTRACT:
A display apparatus includes a plurality of pixels arranged in a matrix. Each pixel includes a light emitting device, a driving transistor for supplying a driving current to the light emitting device, a first switching transistor coupled with the control terminal of the driving transistor to transmit a data voltage, and a second switching transistor coupled with the control terminal of the driving transistor to transmit a reverse voltage. The first and second switching transistors are alternately coupled with scanning lines driven by one of two scanning drivers, and are alternately turned on at different times. The display apparatus periodically applies the reverse voltage to the driving transistors to turn off the diving transistors and to compensate for variation of the threshold voltage of the driving transistors.
