Abstract
Provided are a display panel and a display device. The display panel includes a pixel circuit and a light-emitting element. In the pixel circuit, the gate of a drive transistor is connected to a first node, a reset module includes a first transistor. One end of the first transistor is connected to the first node, and another end is connected to a second node. A compensation module includes a second transistor and a third transistor. The connection node between the second transistor and the third transistor is a third node. Another end of the second transistor is connected to the first node. In one refresh frame, the first transistor and the second transistor are off in a first stage, and a voltage V1 of the first node, a voltage V2 of the second node and a voltage V3 of the third node satisfy V1−V2=K(V3−V2).
