Abstract: An integrated photo-sensing detection display substrate having a subpixel region and an inter-subpixel region. The integrated photo-sensing detection display substrate includes a base substrate; a plurality of light emitting elements on the base substrate and configured to emit light, a portion of the light being totally reflected by a surface thereby forming totally reflected light; a light shielding layer between the plurality of light, emitting elements and the base substrate configured to block at least a portion of diffusedly reflected light from passing through, the light shielding layer having a light path aperture in the inter-subpixel region allowing at least a portion of the totally reflected light to pass through thereby forming a signal-enriched light beam; a diffraction grating layer configured to at least partially collimate the signal-enriched light beam thereby forming a collimated light beam; and a photosensor configured to detect the collimated light beam.

Abstract: A method for preparing a light-emitting layer, the light-emitting layer, an organic light emitting diode (OLED) device, and a display apparatus are provided. The light-emitting layer is prepared by preparing a host material containing a first photocrosslinker group and a guest material containing a second photocrosslinker group. The host material and the guest material are mixed in a solvent to form a mixture. The mixture is coated, annealed, and UV-irradiated on a substrate to form the light-emitting layer. As such, the disclosed light-emitting layer is prepared by the polymerization after being on the substrate. The light-emitting layer has a mesh structure. The mesh structure improves energy transfer between the host material and guest material and increases the lifespan of the resultant OLED device and OLED display apparatus.
