Abstract

Disclosed are a display panel and a driving method. The display panel includes: a substrate, sub-pixels and a switch module. Each sub-pixel includes a pixel drive circuit and a light-emitting element. The pixel drive circuit includes an initialization transistor and a drive transistor, each including a first electrode, a second electrode, and a gate electrode; the first electrode of the initialization transistor is electrically connected to the gate electrode of the drive transistor. The drive transistor provides a drive current to the light-emitting element, the second electrodes of the initialization transistors of at least two sub-pixels are connected to an output terminal of the same switch module. An input terminal of the switch module is electrically connected to an initialization signal terminal. The switch module transfers an initialization signal to the second electrode of the initialization transistor.
