Abstract

Embodiments of the invention provide a flexible display device and a preparation method, and the problem that a flexible active-matrix organic light-emitting diode module is poor in water oxygen barrier effect on the side surface, and the edge is easy to break or peel off can be solved. According to the flexible display device and the preparation method provided by the embodiment, the flexible display device comprises a display substrate and a packaging film layer which is arranged on the surface of the display substrate, wherein the circumferential edge of the packaging film layer comprises aconcave-convex alternated saw tooth structure.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device and a preparation method. Background technique [0002] At present, in display devices, flexible active-matrix organic light emitting diodes (Active-matrix organic light emitting diodes) have become a hot spot for high-end smart products. Since flexible active matrix organic light-emitting diodes have a wider viewing angle, higher refresh rate, and thinner size than traditional liquid crystal displays used in most mobile phones, they improve the visual experience, increase operating speed, and reduce the weight of the mobile phone. [0003] Generally, flexible active matrix organic light-emitting diode modules use thin-film packaging technology to enhance the water-oxygen barrier performance, but the water-oxygen barrier effect on the side is not good; and because the inorganic materials used in the packaging film are relatively brittle, The edge of t...
