Abstract:
The present disclosure provides a display panel, a display device and a driving method. The display panel includes a display substrate and a driving chip. The display panel is configured to write a data signal to a corresponding pixel circuit at a pre-writing phase and a target data writing phase. The driving chip includes a voltage compensation module configured to obtain a compensation voltage value for the pixel circuits in each row in accordance with the quantity of pre-writing phases. Each pixel circuit is configured to write a pre-writing voltage stored in a parasitic capacitor to a gate electrode of a driving transistor in response to a pre-scanning signal at the pre-writing phase, and write a target writing voltage stored in the parasitic capacitor to the gate electrode of the driving transistor in response to a target scanning signal at the target data writing phase.
