Abstract

The invention provides an OLED display panel and a packaging method thereof. The OLED display panel includes: a base substrate, an OLED device disposed on the base substrate, and a thin film encapsulation layer, the thin film encapsulation layer includes a first inorganic layer, an organic layer, and a second inorganic layer, wherein the organic The layer includes a lower surface in contact with the first inorganic layer, an upper surface away from the first inorganic layer, a plurality of sides connecting the upper surface and the lower surface, the upper surface on the base substrate The orthographic projection on is located within the orthographic projection of the lower surface on the base substrate, and each side is inclined; the OLED display panel of the present invention has a long service life and a small edge width, which is conducive to realizing Narrow bezels of products.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a packaging method thereof. Background technique [0002] Organic Light Emitting Display (OLED) has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, flexible display and large-area full-color display, etc. It is recognized by the industry as the display device with the most development potential. [0003] The packaging part of the OLED display panel usually adopts a laminated structure in which inorganic layers, organic layers and inorganic layers are distributed in sequence; among them, the inorganic layer structure is mainly used to prevent the intrusion of water and oxygen, and the organic layer structure is used to improve the stress between the film layer structures. , overriding the role of particles in the environment. In the process of leveling the orga...
