Abstract: Embodiments of the present application provide an array substrate and a manufacturing method thereof, and a display panel. The array substrate includes a substrate, a source electrode, a drain electrode, a semiconductor layer, and a channel defining layer. The semiconductor layer is disposed between the source electrode and the drain electrode, and the semiconductor layer partially overlaps with the source electrode and the drain electrode. The channel defining layer is disposed around the semiconductor layer, and is correspondingly disposed on the source electrode and the drain electrode. When the semiconductor layer is prepared, the semiconductor layer is directly printed in a printing opening defined in the channel defining layer. Overflow of the semiconductor layer is prevented by the channel defining layer.

Abstract: A compensation method a pixel circuit and a display panel are provided. In the compensation method, a gate potential and a source potential of a driving transistor in a writing stage are obtained and a compensation coefficient of the pixel circuit is determined, and then a light-emitting current flowing through the driving transistor in a light-emitting stage is determined based on the compensation coefficient, the gate potential and the source potential of the driving transistor in the writing stage. The compensation coefficient can adjust transmission loss of the gate potential and the source potential of the driving transistor in the writing stage, so as to ensure that the light-emitting current flowing through the driving transistor in the light-emitting stage is desired, without causing the phenomenon of shift in brightness.
