Abstract: A display substrate and a manufacturing method thereof, and a display device, relate to the technical field of displaying. The display substrate includes a base substrate; a pixel defining layer; and a common transport layer arranged at one side of the pixel defining layer away from the base substrate, including a first blocking pattern and first transport patterns located at two sides of the first blocking pattern; the first blocking pattern and the first transport pattern at least including one identical element, material structures of the first blocking pattern and the first transport pattern are different, and a lateral resistance of the first blocking pattern is greater than a lateral resistance of the first transport pattern.

Abstract: A display panel includes a substrate, a first electrode layer, a pixel definition layer, light-emitting patterns, light-absorbing pattern(s) and a second electrode layer. The first electrode layer includes first anodes and at least one second anode. The pixel definition layer is provided with first openings and at least one second opening therein. A first opening corresponds in position to the first anode, and a second opening corresponds in position to the second anode. At least portion of a light-emitting pattern is located in the first opening. At least portion of a light-absorbing pattern is located in the second opening. The second electrode layer covers the light-emitting patterns and the light-absorbing pattern(s). The display panel includes a plurality of sub-pixels and at least one photosensor, and each photosensor is arranged adjacent to at least one sub-pixel. A sub-pixel includes the light-emitting pattern, and a photosensor include the light-absorbing pattern.
