Abstract: The present disclosure provides a pixel structure and a fabrication method thereof, a display substrate and a display apparatus. The pixel structure includes a plurality of first pixel portions arranged in a plurality of rows and a plurality of columns, and a second pixel portion that spaces the plurality of first pixel portions from each other. Each first pixel portion includes a plurality of first sub-pixels having a same color and arranged around a center of the first pixel portion. The second pixel portion includes a plurality of second sub-pixels. For four first pixel portions in two adjacent rows and two adjacent columns, each of four regions that are centrosymmetric and obtained by connecting centers of the four first pixel portions to each other corresponds to one pixel unit, and each pixel unit includes two first sub-pixels respectively in two first pixel portions and at least one second sub-pixel.

Abstract: A pixel unit, a display panel, a display device and a method of manufacturing a pixel unit. The pixel unit includes a first sub-pixel unit and a second sub-pixel unit, each sub-pixel unit includes a first electrode, an emission layer, and a second electrode stacked on a substrate. An emission lifespan of the emission layer of the first sub-pixel unit is smaller than that of the emission layer of the second sub-pixel unit. An area of an orthographic projection of the emission layer of the first sub-pixel unit on the substrate is equal to that of the emission layer of the second sub-pixel unit on the substrate. An area of an orthographic projection of the first electrode of the first sub-pixel unit on the substrate is greater than an area of an orthographic projection of the first electrode of the second sub-pixel unit on the substrate.

Abstract: Embodiments of the present disclosure disclose a display panel and a fabricating method thereof. In the solution, on one hand, water-absorbing magnetic nanoparticles in a packaging layer are distributed along a direction perpendicular to the cover plate at a side far away from an OLED component, or distributed along an extension direction of the packaging layer at a periphery of a region in which the OLED component is located, thus reducing the damage to the OLED component of a display substrate. On the other hand, since the water-absorbing magnetic nanoparticles have magnetic property, the water-absorbing magnetic nanoparticles can be doped in the packaging layer material in a packaging and waterproofing process, and a magnetic field is applied to induce the magnetic nanoparticles to move to the side far away from the OLED component or to the periphery of the region in which the OLED component is located.
