Abstract

The invention provides a display panel which comprises a flexible substrate which comprises a display area and a non-display area surrounding the display area; the planarization layer is arranged on the surface of the flexible substrate; the light-emitting device layer is arranged on the planarization layer of the display area; the retaining wall structure is arranged in the non-display area of the flexible substrate and surrounds the display area, the retaining wall at least comprises a barrier body formed on the flexible substrate, and the barrier body is made of metal; and the thin film packaging layer covers the light emitting device layer and the retaining wall structure.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel. Background technique [0002] With the rapid growth of demand for portable mobile devices and wearable display products, flexible display technology has made great progress in recent years. Among the display technologies that can realize flexible display, OLED (Organic Light Emitting Display, organic light-emitting diode display) is considered to be one of the most flexible display technologies because of its excellent performance such as fast response speed, wide viewing angle, light weight, low power consumption, and high brightness. One of the most promising technologies. [0003] In flexible display panels, the OLED itself in the OLED light-emitting layer is very sensitive to water vapor and oxygen, and OLEDs exposed to water vapor and oxygen will have poor working stability and shortened lifespan. Therefore, it is necessary to use an effecti...
