Abstract:
A display panel includes a plurality of pixels and an electrostatic circuit. At least one pixel includes: a pixel electrode; a common electrode; a light-emitting element; and a driving sub-circuit coupled to a scanning signal terminal, a data signal terminal, a light-emitting control signal terminal, a first voltage signal terminal and a first terminal of a light-emitting element, and outputs a first voltage signal from the first voltage signal terminal to the light-emitting element controlled by a scanning signal, a data signal, and a light-emitting control signal. The electrostatic circuit couples a first signal line and a second signal line, the first signal line receives a second voltage signal, and the second signal line receives a third voltage signal and is arranged on a periphery of the plurality of pixels. Common electrodes of the pixels are coupled to each other and to the second signal line.
