1. A micro-fluidic substrate comprising:
a substrate;
a plurality of driving electrodes on the substrate and configured to drive a droplet to move, the plurality of driving electrodes being in a same layer with a gap space between adjacent driving electrodes,
at least one auxiliary electrode on the substrate and configured to drive the droplet to move, wherein an orthographic projection of the at least one auxiliary electrode on the substrate at least partially overlaps with an orthographic projection of the gap space on the substrate,
wherein the at least one auxiliary electrode is electrically coupled to one of the plurality of driving electrodes adjacent thereto.
