Embodiment 2

[0056] An embodiment of the present invention also provides a packaging method for a flexible display device, including: a process of forming an encapsulation layer, the process of forming an encapsulation layer includes: forming a patterned first film layer; forming a second film layer, the The second film layer at least covers the pattern gap of the first film layer.

[0057] Patterning by etching, regardless of dry etching or wet etching, is easy to cause damage to the film layer that constitutes the light-emitting device, and wet etching is easy to introduce water vapor, so the formation of a water-oxygen barrier layer is selectively masked. The method of patterning the first film layer, the second film layer can be patterned or not, but it should be ensured that the second film layer can at least cover the pattern gap of the first film layer to realize the integrity of the light-emitting device. Covering thus plays a protective role. If the second film layer also adopts ...

Abstract

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 bending cannot be resisted in existing thin film packaging can be solved. The flexible display device comprises a light emitting device and a packaging layer for packaging the light emitting device. The packaging layer comprises a first patterned film layer and a second film layer at least covering the pattern clearance of the first film layer.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible display device and a packaging method for the flexible display device. Background technique [0002] Flexible display devices are about to replace traditional flat panel display devices and become the mainstream in the display field due to their thinness, bendability and impact resistance. Among the display technologies that can realize flexible display at present, OLED (Organic light Emitting Display, organic light-emitting diode display) has excellent performances such as fast response speed, wide viewing angle, high brightness, low power consumption, etc. In recent years, it has become a research hotspot in the field of flexible display. [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 of OLED devi...
