1. A method for driving a light-emitting substrate, wherein the light-emitting substrate comprises: at least one control region, the at least one control region comprises a plurality of light-emitting sub-regions, and the at least one of the plurality of light-emitting sub-regions comprises a plurality of light-emitting elements which are connected in series and/or in parallel; each of the plurality of light-emitting sub-regions comprises a first signal end and a second signal end; in a same light-emitting sub-region, the plurality of light-emitting elements are connected in series and/or in parallel and then connected to the first signal end and the second signal end; in a same control region, the first signal ends of all the light-emitting sub-regions are electrically connected with each other, and the second signal ends of the different light-emitting sub-regions are independent of each other;
wherein the method comprises:
loading a first signal to the first signal ends in the control region; and
loading second signals to the second signal ends of each of the plurality of the light-emitting sub-regions in the control region when a first duration is delayed after the first signal is provided.
