Abstract:
An encapsulated structure of a light-emitting device, an encapsulating process thereof, and a display device comprising said encapsulated structure. The encapsulated structure of the light-emitting device comprises: a light-emitting device; and a protective layer of a quaternary ammonium salt formed on a top electrode of the light-emitting device, the quaternary ammonium salt having the following structure: wherein the anion X− is Cl−, Br−, I− or NO3−; and the substituents R1, R2, and R3 are the same or different.
Abstract:
A method for packaging an organic light emitting diode display panel, comprising providing a desiccant layer on a package cover plate. The desiccant layer is capable of effectively absorbing water and oxygen permeating, edges of the package cover plate and a substrate are hermetically coupled, and the desiccant layer and a device on the substrate are enclosed in a packaging cavity. This method can improve the packaging efficiency of the organic light emitting diode display panel and reduces production costs.
Abstract:
An OLED device, comprising: a first electrode (10), a second electrode (11) and an organic thin film layer (13); the organic thin film layer comprises a hole layer (103), an electron layer (104) and an organic light emitting layer (105) located between the hole layer (103) and the electron layer (104); and the organic thin film layer (13) further comprises a hole blocking layer (12). The organic light emitting layer (105) comprises a first light emitting unit (1051), a second light emitting unit (1052) and a third light emitting unit (1053). A manufacturing method of an OLED device and a display apparatus comprising an OLED device are provided.
