Problems solved by technology

However, due to the use of flexible substrates, which can be bent, cracks or other defects are most likely to appear at the interface of the edge film layer, resulting in the intrusion of water and oxygen, which reduces the accessibility of the package, resulting in the deterioration of the display effect.

Abstract

The invention discloses a flexible display apparatus and a preparation method therefor. The flexible display apparatus comprises a flexible substrate, a packaging substrate, at least one first display film layer, a thin film packaging layer, and an edge packaging structure, wherein the flexible substrate comprises a display region and a packaging region; the packaging substrate is positioned in the packaging region of the flexible substrate; the at least one first display film layer is positioned in the packaging substrate; a first via hole is formed in the first display film layer on the packaging substrate to expose at least a part of the packaging substrate; the first display film layer is covered with the thin film packaging layer, and the thin film packaging layer extends from the display region to the packaging region; the edge of the thin film packaging layer is closer to the display region than the packaging substrate; the edge packaging structure is arranged along the edge of the thin film packaging layer for covering the edge region and the first via hole of the thin film packaging layer, and the edge packaging structure is in contact with the packaging substrate through the first via hole. According to the flexible display apparatus provided by the invention, the edge reliability in the thin film packaging is improved, so that the water oxygen barrier capability is further improved to ensure the display effect of the display apparatus.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible display device and a preparation method of the flexible display device. Background technique [0002] Compared with many displays, OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) displays have many advantages such as active light emission, high contrast, and no viewing angle limitation, especially flexible OLED displays, which have more obvious advantages. Flexible OLED displays are not only lighter and thinner in size, but also lower in power consumption than the original devices, which helps to improve the battery life of the device. At the same time, based on its bendable and flexible characteristics, its durability is also much higher than that of previous screens. , reduce the probability of accidental equipment damage. Therefore, flexible OLED displays are now widely used in the field of display technology. [0003] The flexible OLED display panel is packa...
