1. A light-emitting substrate, comprising:
a base substrate;
an auxiliary electrode line disposed on the base substrate;
at least one light-emitting device disposed above the base substrate, a light-emitting device including a first electrode, a light-emitting functional layer and a second electrode that are sequentially stacked in a direction moving away from the base substrate; and
at least one light-detecting device disposed above the base substrate, a light-detecting device including a third electrode and a fourth electrode; wherein
the fourth electrode of the light-detecting device is disposed on a side of the second electrode of the light-emitting device proximate to the base substrate, and the auxiliary electrode line is disposed on a side of the fourth electrode of the light-detecting device proximate to the base substrate; and
the auxiliary electrode line is coupled to the fourth electrode and the second electrode.
