[0052] image 3 It is a schematic flowchart of a method for manufacturing a flexible display panel in an embodiment of the present invention. Such as image 3 As shown, the present invention provides a method for preparing a flexible flexible display panel, comprising:

[0053] Step S301: forming a separation layer 2 on the rigid base 1, the separation layer 2 is aligned with the edge of the rigid base 1;

[0054] Specifically, a layer of separation layer 2 is formed on the rigid substrate 1 by spin coating or inkjet printing, wherein the separation layer 2 can be coated on the entire surface of the rigid substrate 1, so that the separation layer 2 and the rigid substrate 1 Align the edges. It should be noted that the material of the rigid base 1 can be ceramic material, quartz glass material and the like. The material of the separation layer 2 can be an organic polymer, such as polyimides, silicon organic compounds, or a combination of various organic polymers, or other ...

Abstract

The invention provides a preparation method of a flexible display panel. The preparation method comprises the following steps: forming a separation layer on a rigid substrate, the separation layer being flush with the edge of the rigid substrate; forming at least one groove in the edge area of the separation layer, forming a set distance between the edge of the separation layer and the groove close to the separation layer, and forming a groove opening in the surface, deviating from the rigid substrate, of the separation layer; forming a flexible substrate on the separation layer, and preparinga display element layer on the flexible substrate, wherein the flexible substrate covers the edge area and does not exceed the edge of the separation layer; stripping the flexible substrate from therigid substrate after the flexible substrate is subjected to edge forming in the edge area; and setting the size of the flexible substrate not to be larger than the size of the separation layer, and forming the groove in the edge of the separation layer. Thus the edge can be quickly raised, the problem of difficult edge raising in the preparation process is solved, the peeling reliability is improved, the damage to the flexible substrate is effectively avoided, and the flexible production efficiency and the product yield are improved.

Description

technical field [0001] The invention relates to a method for preparing a flexible display panel, belonging to the technical field of organic light-emitting displays. Background technique [0002] In the field of organic light-emitting display technology, organic light-emitting diodes (Organic Light-Emitting Diode, referred to as: OLED) have excellent advantages such as low power consumption, high brightness, self-luminescence, high color saturation, wide viewing angle, thin thickness, and flexibility. performance, so it is widely used in display devices such as terminal equipment and wearable equipment. [0003] At present, the manufacturing process of flexible OLED display devices is completed on a rigid substrate (such as glass), and the final product needs to be separated from the rigid substrate. In order to facilitate separation, a separation layer (Debonding Layer) is provided between the rigid substrate and the flexible substrate. , referred to as: DBL layer), compar...
