Display substrate, display panel and display device

A display substrate, comprising:

• a substrate;
• and
• a light-emitting device and an optical compensation structure which are located on the substrate, wherein
• the optical compensation structure comprises a photoelectric sensor, a transistor and a capacitor, and the photoelectric sensor is electrically connected to the transistor and the capacitor respectively;
• the photoelectric sensor comprises a first electrode, a photosensitive layer located on a side of the first electrode distal from the substrate, and a second electrode located on a side of the photosensitive layer distal from the substrate;
• the transistor comprises a source electrode, a drain electrode, a gate electrode and an active layer;
• the capacitor comprises a first electrode plate and a second electrode plate located on a side of the first electrode plate distal from the substrate;
• and
• neither an orthographic projection of the source electrode onto the substrate nor an orthographic projection of the drain electrode onto the substrate overlaps with an orthographic projection of the first electrode plate onto the substrate, and both the orthographic projection of the source electrode onto the substrate and the orthographic projection of the drain electrode onto the substrate overlap with an orthographic projection of the first electrode onto the substrate;
• wherein the display substrate further comprises a color filter layer located between the light-emitting device and the photoelectric sensor, and an orthographic projection of the color filter layer onto the substrate does not overlap with an orthographic projection of the photoelectric sensor onto the substrate.
