发明名称 THIN FILM TRANSISTOR CIRCUIT, LIGHT EMITTING DISPLAY APPARATUS, AND DRIVING METHOD THEREOF
摘要 In order to suppress an influence of an electrical stress on a TFT characteristic in use of a TFT, a light emitting display apparatus according to the present invention comprises organic EL devices and driving circuits for driving the organic EL devices. The driving circuit includes plural pixels each having a thin film transistor of which a threshold voltage reversibly changes due to the electrical stress applied between a gate terminal and a source terminal, and a voltage applying unit which sets gate potential of the thin film transistor higher than source potential. The voltage applying unit applies the electrical stress between the gate terminal and the source terminal at a time when the thin film transistor is not driven, so as to drive the thin film transistor in a region that the threshold voltage is saturated to the electrical stress.
