Title
(EN) Flexible display device and preparation method thereof
(ZH) 柔性显示装置及其制备方法
Abstract
(EN)
The invention provides a flexible display device and a preparation method thereof. The flexible display device comprises a flexible display panel with a thin film packaging structure and an elastic layer wrapping the flexible display panel. The preparation method comprises the following steps: preparing the flexible display panel with the thin film packaging structure; and forming the elastic layer wrapping the flexible display panel. According to the invention, a combined packaging structure of in-panel film packaging and out-panel elastic packaging is adopted, so the flexible display devicecan meet the packaging requirements of the water vapor penetration rate and the oxygen penetration rate, also can maintain an original flexible packaging structure, achieves the high flexibility, adaptively adjusts the bending curvature according to the use environment, and improves the reliability in flexible application.
