A preparation method of a flexible touch substrate and the flexible touch substrate

Abstract

The invention discloses a preparation method of a flexible touch substrate and the flexible touch substrate, and the method comprises the steps: forming a hydrophobic film layer on a carrier substrate, and enabling a hydrophobic material in the hydrophobic film layer to be a super-hydrophobic material; Carrying out surface modification treatment on the hydrophobic film layer, so that the surface of one side, far away from the carrier substrate, of the hydrophobic film layer has hydrophilicity; Forming a flexible touch substrate on the surface of one side, far away from the carrier substrate, of the hydrophobic film layer; recovering The hydrophobicity of the hydrophobic film layer; And stripping the flexible touch substrate. According to the invention, the hydrophobic film layer made of the super-hydrophobic material is arranged between the carrier substrate and the flexible touch substrate; The hydrophobic membrane layer is subjected to surface modification treatment to change the surface adhesion of the hydrophobic membrane layer; The flexible touch substrate is stably fixed to the carrier substrate in the preparation stage, the flexible touch substrate can be easily stripped inthe stripping stage, damage to the touch substrate in the stripping process is avoided, and the release yield and efficiency of the flexible touch substrate are improved.

Description

technical field [0001] Embodiments of the present invention relate to touch display technology, and in particular to a method for preparing a flexible touch substrate and the flexible touch substrate. Background technique [0002] In the mobile Internet era, the application of flexible touch screens on mobile phones, the Internet of Things and wearable devices will bring about a new revolution in consumer experience. [0003] At present, most of the preparation methods of flexible touch screens have the same thing, that is, the flexible substrate and the touch device need to be sequentially prepared on the carrier substrate, and then the prepared flexible touch screen is peeled off from the carrier substrate by laser peeling or mechanical peeling. [0004] Typically, laser lift-off methods are costly and less productive. Although the mechanical peeling method has the advantages of low cost and high production efficiency, the mechanical peeling method will easily cause damag...

[0004] Typically, laser lift-off methods are more costly and less productive

Although the method of mechanical peeling has the advantages of low cost and high production efficiency, the method of mechanical peeling will easily cause damage to the flexible touch screen during the peeling process due to the high adhesion between the flexible touch screen and the carrier substrate.
