Abstract

The invention discloses a flexible display panel and a preparation method thereof, and the method comprises the following steps: providing a rigid substrate, and forming a magnetic composite film layer on the rigid substrate; forming a flexible substrate on the magnetic composite film layer; forming an array driving layer on the flexible substrate; forming a light emitting device layer on the array driving layer; forming a packaging layer on the light emitting device layer; and applying a magnetic field to the magnetic composite film layer, so that the magnetic composite film layer deforms and is stripped from the rigid substrate. According to the preparation method provided by the invention, the magnetic composite film layer is additionally arranged, the magnetic field is applied, and stripping is realized under the action of magnetic force of the magnetic field, so a laser stripping process commonly adopted in the prior art is replaced, the problem that a display panel device is easily damaged in a stripping process can be solved, and the stripping technology is simple and convenient to operate; and the stripping yield is relatively high.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display panel and a preparation method thereof. Background technique [0002] With the development of Organic Light-Emitting Diode (OLED) technology, flexible OLED display devices are being intensively studied by major panel manufacturers due to their advantages of being bendable and easy to carry, and have become the main development field of display technology at present. Among them, in the preparation of flexible OLED display panels, how to separate the flexible substrate from the rigid carrier substrate without damaging the display elements is one of the key technologies in the current preparation of flexible OLED display panels. [0003] In the current general method of manufacturing flexible OLED display panels, a flexible substrate is usually coated on a rigid substrate first, and then the array driving layer, organic light-emitting layer and packagin...
