Abstract

The invention, which is suitable for the technical field of the flexible display screen, discloses a manufacturing method for a flexible display screen and a preparing device for a flexible display screen. The manufacturing method comprises: preparing a carrier substrate and a stripping device; setting a stripping separation layer on the carrier substrate; arranging a flexible display screen layer on the stripping separation layer; arranging a support membrane adhering to the flexible display screen layer on the surface of the stripping device; and driving the stripping device, enabling the support membrane to adhering to the flexible display screen layer, and stripping the flexible display screen layer from the stripping separation layer. In addition, the preparing device consists of a stripping device and a flexible display screen layer forming component for forming a flexible display screen layer on a stripping separation layer; and a support membrane that adheres to the flexible display screen layer to strip the flexible display screen layer from the stripping separation layer is arranged on the surface of the stripping device. According to the invention, non-destructive stripping is realized; the product yield is high; the performances are excellent; and the cost is low.
