Abstract:
A pixel circuit for AC driving, a driving method and a display apparatus relate to the field of display manufacture, and are capable of removing effect of internal resistance of a power supply line on the current for light-emitting and effect of the threshold voltage of the driving transistor on the display nonuniformity of a panel while effectively avoiding rapid aging of OLED. The pixel circuit comprises: a capacitor (C1), a first voltage input unit (11), a second voltage input unit (12), a data signal input unit (13), a first light emitting unit (14), a second light emitting unit (15) and a light emitting control unit (16). The present disclosure can be applied in display manufacture.
