Abstract
The present disclosure provides an OLED pixel circuit and a method for retarding the aging of an OLED device. By providing a first sub-pixel driving unit, a second sub-pixel driving unit, a first reverse biasing unit, and a second reverse biasing unit and by simple control timing, a first light emitting diode and a second light emitting diode will not always be in a DC biased state, and the first light emitting diode and the second light emitting diode will emit light alternately in different frames.
