Abstract
Provided are a method for driving a light-emitting substrate, a driving circuit and a display apparatus. The light-emitting substrate includes: at least one control region, which includes a plurality of light-emitting sub-regions, the light-emitting sub-region includes a plurality of light-emitting elements which are connected in series and/or in parallel; each light-emitting sub-regions includes a first signal end and a 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; the method includes: 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.
