    Abstract: The present disclosure generally relates to display technologies. A display substrate includes a first base substrate including a plurality of pixel units arranged in an array, at least one of the plurality of pixel units including at least two sub-pixel units and a transparent area. The at least two sub-pixel units includes a first sub-pixel unit that is arranged between transparent areas of adjacent pixel units in a first direction. An orthographic projection of a pixel drive circuit electrically coupled to the first sub-electrode corresponding to the first sub-pixel unit on the first base substrate partially overlaps with an orthographic projection of a first sub-electrode positionally corresponding to another sub-pixel unit on the first base substrate.
