Abstract: The present disclosure provides a display panel, a display device including the display panel and a method of manufacturing the display panel. The display panel includes a substrate; a pixel-defining layer disposed on the substrate, wherein the pixel-defining layer defines a plurality of sub-pixel regions arranged in rows and columns; and an organic light emitting element disposed in at least one of the plurality of sub-pixel regions, wherein a side of the pixel-defining layer away from the substrate is provided with a groove, the groove has a depth less than a thickness of the pixel-defining layer and the groove is disposed between the organic light emitting elements that are adjacent to each other and emit light of different colors.

Abstract: A protein/polysaccharide/essential oil nano-edible film. The essential oil nano-edible film includes the following raw materials in parts by weight: 1-8 parts of a quinoa protein-Atrina pectinata polysaccharide nanocomposite, 2-11 parts of an Atrina pectinata polysaccharide-essential oil nanocomposite, 1-12 parts of a quinoa protein, 2-16 parts of Atrina pectinata polysaccharide, and 5-53 parts of water. The present invention helps to solve the problem, in a conventional protein film, of the loss of flavor and even toxic side effects caused by the adding of a plasticizer and a crosslinking agent to improve the mechanical strength, the use of a lipid substance that has the capability to easily form a dense molecular network structure to improve the water and gas barrier properties, and the migration of an additive, the plasticizer, or a polymer degradation by-product thereof generated in reaction, and a solvent remaining in the polymerization reaction from the film to food.

Abstract: The present disclosure relates to a method for preparing a conjugated polymer film, as well as a light-emitting diode, a display device, and a solar energy battery including the conjugated polymer film. A method for preparing a conjugated polymer film according to the present disclosure includes: preparing a fibrous conjugated polymer; and preparing a conjugated polymer film from the fibrous conjugated polymer. Since the fibrous conjugated polymer has a certain length and orientation, it has improved electron mobility in the dimensional direction thereof, and is capable of improving the carrier mobility of the conjugated polymer film.
