Abstract

A pixel circuit, a driving method thereof and a display panel are provided. The pixel circuit includes a reset sub-circuit, a compensation sub-circuit, a driving sub-circuit, a control sub-circuit, a data signal writing sub-circuit, a power input sub-circuit and a light emitting device. The compensation sub-circuit may store a compensation voltage for the gate of the driving transistor in the driving sub-circuit, which can alleviate or eliminate the influence of the threshold voltage of the driving transistor on the driving current of the light emitting device, thereby improving the uniformity in brightness of the light emitting device, which enhances the display quality of the display panel.
