1. A display substrate, comprising: a substrate, multiple pixel units arranged on the substrate and a color filter layer arranged on the pixel unit, wherein:
the color filter layer comprises color optical filters of different colors;
the display substrate further comprises a touch control structure layer, the touch control structure layer comprises a touch control connection electrode, a first coating protective layer and a touch control electrode, the touch control electrode comprises a first touch control electrode and a second touch control electrode, and at least one of the first touch control electrode and the second touch control electrode is connected with the touch control connection electrode through a via hole penetrating through the first coating protective layer; and
a pattern of the touch structure layer is arranged between two adjacent color filters, and on at least one plane perpendicular to the substrate, orthographic projections of the touch control structure layer and the color optical filter at least partially overlap,
wherein the touch control electrode comprises a first metal layer and a second metal layer arranged on the first metal layer, and an orthographic projection of the first metal layer on the substrate coincides with an orthographic projection of the second metal layer on the substrate; a reflectivity of the second metal layer is less than a reflectivity of the first metal layer.
