Abstract:
1. A light emitting display apparatus comprising: a plurality of pixels each provided by a light emitting device and a driving circuit including a thin film transistor for controlling a current to be supplied to the light emitting device by applying a voltage between a gate terminal and a source terminal during a displaying period of the light emitting display apparatus; and a voltage applying unit for applying voltages to the thin film transistor during a non-displaying period of the light emitting display apparatus, wherein the thin film transistor has a property of shifting threshold voltage by an electrical stress to be applied between the gate terminal and the source terminal, and wherein the voltage applying unit applies a voltage to the drain terminal being-equal to a voltage of the source terminal, and applies a voltage between the gate terminal and the source terminal during the non-displaying period of a same polarity as the voltage between the gate terminal and the source terminal applied in the displaying period.
