Abstract

The embodiment of the invention discloses a flexible display device and a packaging method of the flexible display device, and relates to the field of display. The problem that cracks easily occur in an existing packaging film layer can be solved, and bending resistance of the flexible display device can be improved. The flexible display device comprises an OLED, and a protective layer arranged on a cathode of the OLED. The protective layer comprises a water and oxygen blocking area and a multifunctional area. The multifunctional area has dual functions, namely, the water and oxygen blocking function and the stress cut-off function, and the thickness of the film layer of the multifunctional area is smaller than that of the film layer of the water and oxygen blocking area; or the film layer of the multifunctional area is looser than the film layer of the water and oxygen blocking area; or the thickness of the film layer of the multifunctional area is smaller than that of the film layer of the water and oxygen blocking area, and meanwhile the film layer of the multifunctional area is looser than the film layer of the water and oxygen blocking area.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible display device and a packaging method thereof. Background technique [0002] The development of traditional flat panel display device technology has become increasingly mature, and flexible display devices are about to become the mainstream in the display field due to their thinness, bendability, and impact resistance. Among them, OLED (Organic Light Emitting Display, organic laser display) has become a flexible display field in recent years because of its fast response speed, wide viewing angle, high brightness, low power consumption, self-luminous device, and excellent performance such as anti-bending characteristics. One of the hotspots of research. [0003] OLED devices are very sensitive to water vapor and oxygen, and are prone to attenuation. Effective packaging can prevent the intrusion of water vapor and oxygen, prevent the aging of organic materials, and prolong the life ...
