Abstract

A peeling method for a flexible display panel, comprising the steps of: providing a carrier substrate, forming an automatic peeling adhesive layer on the carrier substrate; forming a flexible display panel on the automatic peeling adhesive layer; automatically releasing the adhesive layer to irradiate with ultraviolet light; and the automatically releasing adhesive layer generates gas to automatically separate the flexible display panel from the carrier substrate. The peeling method of the flexible display panel provided by the present invention can automatically peel the flexible display panel, improve the peeling yield of the product, and reduce the production cost without using laser equipment.

Description

technical field [0001] The invention relates to a peeling method of a flexible display panel, which belongs to the technical field of flexible display. Background technique [0002] Organic light emitting diode (OLED, Organic Light Emitting Display) display device has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, and wide operating temperature range, which can realize flexible display and With many advantages such as large-area full-color display, the application range is more and more extensive, and it is recognized by the industry as the display device with the most development potential. With the development of OLED technology, flexible OLED display panels have been produced by utilizing the flexible advantages of OLEDs. Because of their characteristics of being bendable and easy to carry, they have become the main field of research and development in the field of display tec...
