Abstract

The invention provides a flexible display panel and a preparation method thereof. The flexible display panel is prepared on a rigid substrate. In order to facilitate peeling off the rigid substrate, a thermosensitive adhesive layer is arranged between the flexible display panel and the rigid substrate. Inside the thermosensitive adhesive layer Doped with magnetocaloric particles, under the action of a magnetic field, the temperature of the magnetocaloric particles rises, resulting in a change in the volume of the magnetocaloric particles, and at the same time heating the heat-sensitive adhesive layer, reducing the viscosity of the heat-sensitive adhesive layer, resulting in a The layer and the rigid substrate are automatically peeled off to complete the preparation of the flexible display panel, and the flexible substrate and the rigid substrate can be simply peeled off, thereby improving the success rate of peeling.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel and a preparation method thereof. Background technique [0002] Flexible Organic Light-Emitting Diode (OLED) panels have become an important research direction of organic light-emitting devices. Flexible substrates are selected to replace traditional glass substrates to achieve the flexibility of panels. Commonly used flexible substrates include metal films. (aluminum foil or copper foil) and polymer films (such as polyimide, etc.). Compared with metal films and polymer films, the latter has good flexibility and is light and thin. When making OLED devices with polymer films as flexible substrates, polymer emulsions are often uniformly coated on the carrier substrate to obtain polymer films. Then, the OLED device is fabricated on the polymer film, and after the OLED device is fabricated, the polymer film is peeled off from the carrier substrate. ...
