Display panel and display device

A display panel, comprising:

• a pixel circuit, and
• a light-emitting element, wherein:
• the pixel circuit includes a driving transistor configured to provide a driving current for the light-emitting element;
• a working process of the pixel circuit includes a data writing stage and a bias adjustment stage, wherein a gate of the driving transistor receives a data signal in the data writing stage, and a source or drain of the driving transistor receives a bias adjustment signal in the bias adjustment stage;
• a frame refresh frequency of the pixel circuit is F1, and a frame includes a data writing frame and a holding frame;
• and
• a data refresh frequency of the pixel circuit includes a first data refresh frequency F11 and a second data refresh frequency F22, F22<F11≤F1, wherein:
• after the data refresh frequency of the pixel circuit is switched from the first data refresh frequency F11 to the second data refresh frequency F22, one second data refresh period includes a total of N11 bias adjustment stages, N11≥2, a bias adjustment signal Vm is inputted in a m-th bias adjustment stage of the second data refresh period, and a bias adjustment signal Vn is inputted in an n-th bias adjustment stage, 1≤m≤N11, 1≤n≤N11, m<n:
• wherein:
• Vm≠Vn.
