Abstract
The present invention provides an OLED display panel and a manufacturing thereof, and an OLED device. The OLED display panel adopts organic host materials, organic light-emitting materials, and amorphous fluoropolymers to produce a light-emitting layer, so that amorphous polymers improve thermal stability and solvent resistance of the light-emitting layer, and the light-emitting layer is not damaged by solvents when an electron transport layer is formed by solvents, thereby resolving the process of processing OLED devices by solvents having damage to the light-emitting layer causing poor display performance in the prior art.
