Manufacturing method for flexible OLED and flexible OLED

Abstract

The invention provides a manufacturing method for a flexible OLED and the flexible OLED. The manufacturing method for the flexible OLED comprises the following steps of: by taking a magnetic substrate as a carrier base plate, fixing a flexible magnetic film on the magnetic substrate through magnetic adsorption, forming a polymer film on the flexible magnetic film, manufacturing an OLED device on the polymer film, and encapsulating the OLED device, thereby manufacturing the flexible OLED. The manufacturing method is simple, by demagnetizing the magnetic substrate, lossless separation of the flexible magnetic film and the magnetic substrate can be achieved; in addition, the flexible magnetic film is optionally a metal film with good moisture blocking properties, moisture permeation rate can be reduced, and the stability of the OLED device can be improved. By encapsulating the OLED device, the reliability of the properties of the OLED device is further improved. The flexible OLED provided by the invention is simple in manufacturing process and excellent in property.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a flexible OLED and the flexible OLED. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) display, also known as organic electroluminescent display, is a new flat panel display device, due to its simple manufacturing process, low cost, low power consumption, high luminous brightness, Wide range of working temperature, light and thin size, fast response speed, easy to realize color display and large-screen display, easy to realize matching with integrated circuit driver, easy to realize flexible display, etc., so it has broad application prospects. [0003] Flexible OLED panels have become an important research direction for organic light-emitting devices. Flexible substrates are chosen to replace traditional glass substrates to achieve panel flexibility. Commonly used flexible substrates include metal films ...

Problems solved by technology

[0005] In addition, organic light-emitting devices are very sensitive to water vapor and oxygen, and the penetration of water and oxygen will greatly reduce the life of the device. The polymer substrate has a loose structure and pores due to its small molecular weight and loose cross-linking between molecular chains. More, increasing the possibility of water vapor entering the device
