Abstract

The invention discloses a release layer structure, a substrate structure and a preparation method of a display panel, and the release layer structure comprises: a thermal induction layer which is in contact with a local surface of a display substrate in a strippable manner; and a heat conduction layer which is arranged between the thermal induction layer and the substrate base plate so as to provide heat energy for a local surface of the display base plate through the thermal induction layer. According to the release layer structure, the substrate structure and the preparation method of the display panel provided by the invention, the heat conduction layer and the thermal induction layer are arranged between the display substrate and the substrate, different positions of the display substrate are heated unevenly in the stripping process, the stripping force between the display substrate and the thermal induction layer is reduced, and therefore the display substrate and the underlayer substrate can be separated rapidly without damage, and the stripping cost is low.

Description

technical field [0001] The present invention relates to the field of flexible display technology, more specifically, to a release layer structure and a method for preparing a display panel. Background technique [0002] Flexible display devices usually use flexible substrates to carry thin-film transistors, organic light-emitting diodes (Organic Light-Emitting Diode, OLED) and other devices, so flexible display devices can be bent, which has huge potential advantages in the display market. [0003] In the traditional manufacturing method of flexible display devices, flexible substrate materials are usually coated on a rigid substrate to form a flexible substrate, and then electronic or optical devices are fabricated on the flexible substrate, and then peeled off by laser irradiation , that is, a high-intensity laser is applied at the interface between the flexible substrate and the rigid substrate (such as glass) to separate the flexible substrate from the rigid substrate. ...
