Abstract

The invention discloses a flexible display panel. The flexible display panel comprises a bending area and plane display areas located on the two sides of the bending area., t The flexible display panel comprises a flexible substrate, an array substrate, a light-emitting function layer and a packaging layer which are arranged in a stacked mode, and in the bending area, a stress release structure isformed on the packaging layer in the bending direction. When the flexible display panel is bent, a a stress release space is provided for the flexible display panel by arranging the stress release structure in the bending direction of the packaging layer, so that the effects of reducing stress generated during bending and increasing the bending frequency of the flexible display panel are achieved.

Description

technical field [0001] The present application relates to the display field, in particular to a display module and a display device thereof. Background technique [0002] Self-luminous devices such as OLEDs have the characteristics of self-luminescence, wide viewing angle, long life, energy saving and environmental protection. At present, the OLED display and lighting industry is developing rapidly and has become an important display design. Among them, thin film encapsulation is a preferred encapsulation method applied to self-luminous devices such as OLEDs. The purpose of blocking water and oxygen is achieved by depositing various functional layer films on the surface of the OLED substrate, without using other cover plates, and it is easy to realize flexible display. At present, flexible display panels use thin-film packaging as the main packaging method. Thin-film encapsulation mainly achieves the encapsulation effect by stacking inorganic layers and organic layers. Ho...
