OLED display substrate exhibiting improved brightness and including white sub-pixel unit overlapping plurality of signal lines

A display substrate, comprising:

• a first base substrate comprising a plurality of pixel units arranged in an array, wherein a pixel unit includes a transparent area, a white sub-pixel unit, at least two color sub-pixel units, and a plurality of signal wires, and the pixel unit is one of the plurality of pixel units;
• a first electrode layer, a second electrode layer, and a light-emitting layer on the first base substrate, wherein the first electrode layer includes a plurality of first sub-electrodes;
• and
• a plurality of pixel drive circuits, wherein each of the plurality of pixel drive circuits is electrically coupled to a corresponding one of the plurality of first sub-electrodes;
• wherein an orthographic projection of the white sub-pixel unit on the first base substrate partially overlaps with an orthographic projection of the plurality of signal wires on the first base substrate;
• an orthographic projection of a pixel drive circuit of the plurality of pixel drive circuits corresponding to a first sub-electrode of the white sub-pixel unit on the first base substrate partially overlaps with an orthographic projection of a first sub-electrode of one of the at least two color sub-pixel units on the first base substrate, and the first sub-electrode of the one of the at least two color sub-pixel units is electrically coupled to the one of the at least two color sub-pixel units adjacent to the white sub-pixel unit.
