Abstract
An organic electroluminescent display substrate is provided, which includes a base substrate, and a light-emitting unit and a light-sensing unit arranged on the base substrate, wherein the light-sensing unit is arranged on a light-emitting side of the light-emitting unit, and configured for sensing an intensity of light emitted from the light-emitting unit; a first planarization layer is arranged between the light-sensing unit and the light-emitting unit; the light-sensing unit comprises a first thin film transistor and a photosensitive sensor arranged sequentially in that order in a direction away from the base substrate, and a second planarization layer is arranged between the photosensitive sensor and the first thin film transistor. A display panel, a display device and a method for manufacturing the organic electroluminescent display substrate are further provided.
