Zusammenfassung:An OLED pixel circuit and a method for retarding ageing of an OLED device. Providing a first sub-pixel drive unit (101), a second sub-pixel drive unit (102), a first reverse bias unit (103) and a second reverse bias unit (104), along with a simple control time sequence, to enable a first light-emitting diode (OLED1) and a second light-emitting diode (OLED2) not to be always in a direct current bias state, and the first light-emitting diode (OLED1) and the second light-emitting diode (OLED2) to illuminate alternately during different image frames.
