Abstract
The application discloses a pixel circuit and a driving method thereof. By synchronously resetting a potential of an input end of a light-emitting unit and a potential of a control end of a driving unit, the input end of the light-emitting unit can obtain a longer reset time; when the light-emitting unit emits light, a resetting transistor and an initialization transistor are both in an off state, which can better prevent leakage of the input end of the light-emitting unit, thereby improving display effect of the pixel circuit in a dark state or low gray level.
