  • Publication number: 20240122047
    Abstract: A display substrate includes an underlaying substrate, a display structure layer arranged on the underlaying substrate, and a light regulation layer arranged at a light exiting side of the display structure layer. The display structure layer includes multiple sub-pixels. An orthographic projection of the light regulation layer on the underlaying substrate does not overlap with opening regions of the multiple sub-pixels. The light regulation layer is configured to adjust an emergent direction of light of at least one color emitted from the display structure layer.

  • Publication number: 20220130927
    Abstract: Provided is a method for manufacturing a display panel. First, the method includes sequentially preparing an anode layer and a first pixel define layer on a side of a substrate layer, then coating an organic light-induced material on a first surface, distal from the anode layer, of the first pixel define layer, and forming a polymer film layer by reacting the first pixel define layer with the organic light-induced material under a predetermined condition, and then preparing an organic functional layer and a cathode layer on a surface, distal from the first pixel define layer, of the organic light-induced material. The organic light-induced material at least contains a hydroxyl group and an unsaturated carbon-carbon double bond.
