Abstract
Provided are a display substrate, a preparation method thereof, and a display apparatus. The display substrate includes: a base substrate, a light emitting structure layer disposed on the base substrate, a color filter layer including a plurality of sub-pixels and disposed on a light emitting side of the light emitting structure layer, and a pinhole thin film structure layer disposed on a light emitting side of the color filter layer, the pinhole thin film structure layer including a plurality of amplification structures, the amplification structures corresponding to the sub-pixels one by one, and an orthographic projection of the amplification structures on the base substrate being inside an orthographic projection of the sub-pixels corresponding to the amplification structures on the base substrate, and the amplification structures being configured to amplify images of the sub-pixels corresponding to the amplification structures.
