    摘要: A pixel driver circuit includes a driving transistor T1 connected in series to a light-emitting element, a capacitor C, a first end of which is connected to a gate electrode of T1 and a second end of which is connected to a source electrode of T1, and a charging circuit at least including a current source and configured to charge C at a charging stage. Within at least a part of time period of the charging stage, an intensity of a charging current for charging C is greater than an intensity of a target current, and after the charging stage, a voltage difference across C is equal to a target voltage difference. When the light-emitting element emits light at a preset brightness value at a light-emitting stage, the target voltage difference is a gate-to-source voltage difference of T1 and the target current is a current flowing through T1.
