1. A driving backplate, comprising:
a substrate;
a reflective layer disposed on a side of the substrate, and comprising a plurality of openings;
a plurality of electronic devices disposed on a side of the reflective layer away from the substrate, and disposed to correspond to the plurality of openings one-to-one; and
a plurality of connection components disposed in the openings and corresponding to the plurality of openings, wherein a first end of each of the connection components close to the substrate is connected to the substrate, and a second end of each of the connection components close to the electronic devices is connected to each of the electronic devices;
wherein the reflective layer comprises a plurality of overlapping parts disposed adjacent to the openings and corresponding to the plurality of openings, and an orthogonal projection of each of the overlapping parts on a plane of the substrate overlaps with an orthogonal projection of a part of each of the electronic devices on the plane of the substrate; and
wherein a thickness of the connection components is greater than or equal to a thickness of the overlapping parts.
