Abstract
Provided are a display panel, a driving method thereof and a display device. The display panel includes: a pixel circuit and a light-emitting element, where the pixel circuit includes a light emitting control module, a drive module and a compensation module; the light emitting control module includes a first light emitting control module configured to selectively provide a first power supply signal for the drive module; the drive module is configured to provide a drive current for the light-emitting element and comprises a drive transistor; the compensation module is configured to compensate a threshold voltage of the drive transistor; and a working process of the pixel circuit includes a light emitting stage and a bias stage.
