Abstract:
A display panel and a display device are provided. The display panel includes a plurality of sub-pixels. Each sub-pixel includes a pixel circuit and a light-emitting element. The pixel circuit includes a driving module, a compensation module, and a voltage regulation module. The compensation module includes a first double-gate transistor, and the first double-gate transistor includes a middle node. First and second electrodes of the first double-gate transistor are electrically connected to a control terminal and a second terminal of the driving module, respectively. A gate of the first double-gate transistor is connected to a first scan line providing a first scan signal. First and second terminals of the voltage regulation module are electrically connected to the middle node and a second scan line providing a second scan signal, respectively. A phase of the second scan signal is opposite to a phase of the first scan signal.
