1. A display substrate, comprising:
a substrate;
a first electrode located on the substrate; and
a conductive convex located on the first electrode,
wherein a dimension of a cross section of the conductive convex along a plane parallel to the substrate is negatively correlated to a distance from the cross section to a surface of the first electrode, and
wherein a ratio of a minimum dimension of a surface of a side of the conductive convex facing the substrate along a direction parallel to the substrate to a distance from the conductive convex to the first electrode ranges from 1:1 to 1:3, and
wherein the conductive convex comprises a first portion, a second portion covering the first portion, and an inorganic material layer covering the first portion, the inorganic material layer being located between the first portion and the second portion, and
wherein an orthographic projection of the first portion on the substrate is located within an orthographic projection of the first electrode on the substrate,
the second portion is in contact with the first electrode,
a surface of the second portion away from the substrate is conformal to a surface of the first portion away from the substrate, and
the first portion is composed of a dielectric material, the dielectric material comprises an organic material, and the second portion is composed of a conductive material.
