发明名称 DISPLAY DEVICE AND DRIVING METHOD THEREOF
摘要 A display apparatus and a driving method thereof are provided to prevent the deterioration of image quality by preventing transition of a threshold voltage of an amorphous Si thin film transistor. A display apparatus includes a light emitting element(LD) and a driving transistor(Qd) for supplying a driving current to the light emitting element. Data or inverse bias voltages are alternately supplied to the driving transistor. The inverse bias voltage is an AC(Alternating Current) voltage. The display apparatus includes first and second switching transistors(Qs1,Qs2), which are connected to the driving transistor, for delivering the data and inverse bias voltages according to scan and switching signal, respectively.
