Claim 0:
1. 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:
at least one second data refresh period includes N11 bias adjustment stages, N11≥2, a bias adjustment signal V11 is inputted in a first bias adjustment stage of the second data refresh period, and a bias adjustment signal Vi is inputted in an i-th bias adjustment stage, 1<i≤N11, wherein: V11≠Vi and the bias adjustment signal V11 input in the first bias adjustment stage satisfies 5V≤V11≤6.5V; or the bias adjustment signal Vi input in the i-th bias adjustment stage satisfies 5V≤Vi≤6.5V.
