Abstract: An OLED display panel and a display device are provided. The OLED display panel includes doped light emitting layers formed by doping the same main blue fluorescent luminescent material with the same secondary thermally activated delayed fluorescence material. A doping concentration of the secondary material in a first doped light emitting layer and a doping concentration of the secondary material in a second doped light emitting layer are different. It is advantageous for different light emitting layers to emit different wavelengths so as to realize generating multiple electroluminescence peaks, broaden the luminescence spectrum, improve a color rendering index, and thus achieve the effect of simplifying a light emitting layer structure.

Abstract: The present invention provides a substrate and a manufacturing method of the substrate. The substrate includes: a glass base plate; a first base layer on the glass base plate; a light shielding layer on the first base layer; multiple pixel units placed on the first base layer, the pixel units including at least one light transmissive region; and a photomask for exposing the light shielding layer. The photomask is used to expose, develop, and etch away a portion of the light shielding layer on the pixel units which need to communicate with each other, so that multiple grooves are formed in the light shielding layer to make the pixel units communicate with each other.

Abstract: A manufacturing method of a rhodamine dye oligomer, a solid color material, and a liquid crystal display device are provided. By oligomerization of rhodamine dyes, monodispersion of rhodamine dyes can be achieved, preventing the enhanced shoulder peak caused by aggregation of rhodamine dye molecules, Meanwhile, the purification of color gamut is achieved, and the thermal stability of rhodamine dyes is increased, thereby meeting the need of liquid crystal display devices. Moreover, applying the rhodamine dye oligomer to the solid color material and fabricating the solid color film for application in the liquid crystal display devices can prevent a great loss of brightness of display devices.
