Claim 26:
27. 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 data refresh frequency of the pixel circuit includes a first data refresh frequency F11, a second data refresh frequency F22, a third data refresh frequency F33, F33<F22<F11, 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 N11 bias adjustment stages, N11≥2, a bias adjustment signal V11 input in a first bias adjustment stage of the second data refresh period, a bias adjustment signal Vi input in an i-th bias adjustment stage, 1<i≤N11;
after the data refresh frequency of the pixel circuit is switched from the first data refresh frequency F11 to the third data refresh frequency F33, one third data refresh period includes N12 bias adjustment stages, N12≥2, a bias adjustment signal V12 input in a first bias adjustment stage of the third data refresh period, a bias adjustment signal Vj input in a j-th bias adjustment stage, 1<j≤N12;
bias adjustment signals input in i bias adjustment stages between the first bias adjustment stage to the i-th bias adjustment stage of the second data refresh period decrease sequentially; and
bias adjustment signals input in j bias adjustment stages between the first bias adjustment stage to the j-th bias adjustment stage of the third data refresh period decrease sequentially.
