Abstract: A display substrate has a display region. The display region includes at least a first region, and the first region includes a plurality of first sub-pixel regions. The display substrate includes: a substrate; a plurality of first sub-pixels disposed on a side of the substrate; and a pattern layer disposed on a side of the plurality of first sub-pixels away from the substrate. The pattern layer includes a first pattern and a plurality of second patterns. Boundaries of orthographic projections of part of the second patterns located in the first region on the substrate respectively coincide with boundaries of the first sub-pixel regions; or boundaries of the first sub-pixel regions are respectively located within boundaries of orthographic projections of part of the second patterns located in the first region on the substrate. A portion of the first pattern located in the first region is electrically connected to the first cathode.

Abstract: The present application provides display panels, transparent display panels and manufacturing methods therefor. A transparent display panel includes a light transmitting substrate, pixel structures, second electrode connecting portions, and a nano-material layer. A display region of the light transmitting substrate includes alternately distributed pixel regions and non-pixel regions. The pixel structures are located in the pixel regions, each including: a first electrode close to the light transmitting substrate, a second electrode away from the light transmitting substrate, and a light emitting block between the first electrode and the second electrode. The second electrode connecting portions are located in the non-pixel regions, and connect adjacent second electrodes, and one or more materials for the second electrode connecting portions are the same as the one or more materials for the second electrodes, both including transflective materials. The nano-material layer includes a plurality of nano-island structures separated from each other, and is located at least on a side of the second electrode connecting portions away from the light transmitting substrate, and is configured to excite surface plasma polaritons corresponding to infrared light and scatter the infrared light.
