Abstract: The present disclosure relates to a package structure of organic light emitting diode (OLED) components. The package structure includes an OLED body and an encapsulation layer having an organic layer, a protecting layer, a blocking layer, and a stressed layer. A first curved-surface area is formed on the organic layer, and the protecting layer, the blocking layer, and the stressed layer are stacked on the organic layer in sequence. The protecting layer, the blocking layer, and the stressed layer are respectively formed with a second curved-surface area. The second curved-surface area is stacked on the first curved-surface area and is overlapped with the first curved-surface area, and the second curved-surface area and the first curved-surface area form a folded area of the encapsulation layer. The present disclosure also relates to one OLED component and a display panel.

Abstract: The present invention provides an organic light-emitting display apparatus where an organic light-emitting device comprises an anode layer, a cathode layer, and an organic light-emitting dielectric layer disposed between the anode layer and the cathode layer; organic light-emitting dielectric layer comprises a hole injection layer, a hole transporting layer, a first mixed layer, an emission layer, an electron transporting layer, and an electron injection layer sequentially disposed; wherein first mixed layer is a mixed material layer consisting of a hole transporting material and an electron transporting material, and first mixed layer is doped with either of a material having an electron blocking function and a material having a hole control function. It can decrease injection barrier of carriers of holes and electrons in the organic light-emitting device, control carrier injection rate and position of carrier recombination region, and raise the recombination efficiency of the carriers, thereby achieving a high efficiency, long lifetime organic light-emitting device.
