Problems solved by technology

In the narrow frame / frameless flexible display technology, the bending area of ​​the flexible display is usually covered with a lot of metal traces. After the product is bent, the metal traces in the bending area are under greater stress. Since the stress of the metal traces cannot be released in time, it is easy to The occurrence of stress concentration leads to cracks or even breakage of the metal wiring, leading to an increase in the resistance of the metal wiring or failure of the product display, which seriously affects the service life of the flexible display

Abstract

The invention discloses a flexible display panel and a preparation method thereof, and a flexible display device. As a partial metal routing section in a bending area of the flexible display panel isa double layer structure, the routing of a second metal layer can adopt a design of wavy routing, so that stresses on metal routing during bending can be reduced, the probability of the cracking of the metal routing in the bending area of a flexible display can be decreased, and the stabilization of the resistance value of the metal routing can be ensured; and the effect of enhancing reliability can be achieved through the connection part of the routing of a first metal layer and the routing of the second metal layer, and therefore, the probability of abnormal display caused by the cracking ofthe metal routing can be reduced, and normal signal transmission can be ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel, a flexible display device and a method for preparing a flexible display panel. Background technique [0002] As a new generation of display products, flexible display devices have attracted more and more attention due to their advantages such as ultra-light, ultra-thin, high-definition, fast response, bendable, and easy to carry. With the continuous update of display panel technology, small-sized panels are developing in the direction of thinner, thinner and borderless, and the pad bending is the core technology of narrow border / bezel-less, which can generally be achieved at present. The bending radius is less than 0.5mm. [0003] Flexible displays need to be rolled up or bent, or even bent frequently, during use. In the narrow frame / frameless flexible display technology, the bending area of ​​the flexible display is usually covered with a lot...
