Problems solved by technology

[0004] However, the thermal ductility and film layer defects (pinholes, bubbles) of the plastic substrate in the flexible OLED display panel are a major problem affecting product quality, especially the film layer defects in the process of making the plastic substrate, resulting in the growth of its surface. The barrier layer also inherits its shortcomings and defects, which may cause the substrate to lose water and oxygen barrier capabilities, resulting in product failure
Moreover, the surface of the existing flexible OLED display panel has poor scratch resistance

Abstract

The embodiment of the invention provides a flexible OLED display panel and a manufacturing method thereof. The flexible OLED display panel is stronger in water proof and oxygen proof capability, thinin thickness and is strong in scratch resistance capability. The flexible OLED display panel includes an array substrate and a package substrate. The array substrate includes a substrate, an OLED element disposed on each sub-pixel on the substrate and a packaging film covering the OLED element. The package substrate is a tempered glass substrate, wherein the substrate material comprises inorganicmaterials and / or metal materials having the capability of blocking water and oxygen, and the etching rate the inorganic materials or the metal materials by a glass etching solution is smaller than the etching rate of the glass. The invention is applicable to a flexible, foldable and revoluble flexible display apparatus.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible OLED display panel and a preparation method thereof. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, referred to as OLED) display is flexible because of its material and structure, which provides the possibility for the diversity of product forms, such as non-planar special-shaped displays, non-fixed shape folding, curling monitor. However, in order to realize the bendable characteristics of OLED displays, the substrate substrate and packaging form of OLED displays are the biggest technical obstacles. [0003] At present, the substrate of the flexible OLED display panel uses a barrier layer and a plastic substrate together as the substrate; wherein, the material of the barrier layer is an inorganic material, the plastic substrate is an organic material (such as polyimide), and the barrier layer is on the plastic substrate. G...
