Abstract
Provided are a display panel and a display device. The display panel includes a first display region, a second display region and pixel circuits. The pixel circuits include a first pixel circuit and a second pixel circuit. The first pixel circuit is configured to provide a drive current for a light-emitting element in the first display region. The second pixel circuit is configured to provide a drive current for a light-emitting element in the second display region. The pixel circuits further include at least one bias adjustment module, each of which is configured to provide a bias adjustment signal for a respective one drive transistor. A preset electrode of a drive transistor in the first pixel circuit is connected to one bias adjustment module and a preset electrode of a drive transistor in the second pixel circuit is connected to no bias adjustment module.
