摘要： 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.

摘要： A display panel and a manufacturing method thereof are provided. The display panel includes a substrate, a display device and an encapsulant, and the display device are arranged on the substrate. The encapsulant covers the edge of the display device and the substrate. The encapsulant includes at least two inorganic encapsulation layers and at least one organic encapsulation layer; the at least two inorganic encapsulating layers and the at least one organic encapsulating layer are alternately stacked with each other and integrated as a whole in a direction perpendicular to the substrate. Thus, the display device in the display panel can be prevented from contacting with water and oxygen.

摘要： The present invention provides an OLED packaging method and an OLED package structure. The OLED packaging method according to the present invention is such that a first outer bound confinement layer is first formed and then, a first organic layer is formed on the first inorganic layer in an area enclosed by the first outer bound confinement layer so that facilities for forming the first organic layer can be diversified and an organic material used to form the first organic layer is not subjected to constraint in respect of viscosity thereof, whereby using an organic material with a reduced viscosity allows for better homogeneity of the first organic layer, the thickness reduced, and thus helping reduce a curving radius of the OLED package structure to realize rollable displaying with a reduced curving radius. Further, the first outer bound confinement layer helps block external moisture and oxygen from corroding the first organic layer in a sideway direction so that the OLED package structure so manufactured exhibits better capability for blocking moisture and oxygen and extended service life. The OLED package structure according to the present invention allows for realization of rollable displaying with a reduced curving radius and also exhibits better capability for blocking moisture and oxygen and extended service life.
