Abstract

A method for manufacturing a flexible display panel includes coating a glass substrate with a flexible thin film material to form a substrate; fabricating an array layer and an OLED device layer on the substrate; using a laser stripping method to carry out primary separation between that glass substrate and the substrate; using a cooling mode to perform secondary separation between the glass substrate and the substrate. The invention can complete the separation of the glass substrate and the substrate without contacting the substrate, and effectively prevents the substrate from being damaged in the separation process. The invention also provides a flexible display panel manufactured by the method.

Description

technical field [0001] The invention relates to the technical field of flexible display manufacturing, in particular to a flexible display panel and a manufacturing method thereof. Background technique [0002] With the maturity of the flexible display manufacturing technology, it is possible to use the precision coating process to make high-temperature-resistant flexible film materials on the glass substrate to form the substrate substrate, and then make the OLED device layer on the surface of the substrate substrate, and finally in the module In engineering, laser lift off (LLO) is used to separate the glass substrate from the substrate substrate of the flexible display panel. However, the laser lift-off process is subject to interference factors such as foreign objects and laser energy fluctuations. After laser lift-off, the separation of the glass substrate and the flexible display panel may not be complete. In this case, it is necessary to add a De-lami auxiliary proces...
