Flexible touch control cover plate, preparation method thereof and flexible touch control display screen

Abstract

The invention discloses a flexible touch control cover plate, a preparation method thereof and a flexible touch control display screen. The flexible touch control cover plate comprises a flexible bendable transparent base material, wherein the flexible bendable transparent base material is provided with a first surface and a second surface opposite to the first surface; a hardened layer which is arranged opposite to the first surface and is used for increasing the surface hardness and / or preventing fingerprints; an isolation layer which is arranged opposite to the second surface and used for isolating water vapor; a shielding layer and the touch layer are arranged on the side, deviating from the transparent base material, of the isolation layer, and a shielding layer surrounds the touch layer; the shielding layer is lightproof; wherein the shielding layer comprises a connecting area; the touch layer comprises a first conducting layer, a second conducting layer and an insulating layer located between the first conducting layer and the second conducting layer. The first conducting layer and the second conducting layer are touch electrode layers of a grid structure. By applying the flexible touch control cover plate provided by the invention, the light and thin design of the flexible touch display screen can be realized, the tedious degree of preparation of the flexible touch display screen is reduced, and the yield of the flexible touch display screen is improved.

Description

technical field [0001] The invention relates to the technical field of touch display, and more specifically, to a flexible touch cover, a preparation method thereof, and a flexible touch display. Background technique [0002] With the continuous development of touch screen technology, flexible OLED (Organic Light-Emitting Diode, organic light-emitting diode) display has attracted extensive attention due to its characteristics of self-illumination, bendability, and low power consumption. It uses a flexible cover as the cover . [0003] At present, the existing flexible OLED display screen generally realizes the touch function through two structures, the plug-in type and the on-cell type. Among them, the plug-in type includes flexible cover plate, optical glue, touch sensor with substrate, optical glue, and flexible OLED from top to bottom. The cover plate and the touch sensor are bonded together, and then the touch sensor and the flexible OLED are bonded together through op...

AI Technical Summary

Problems solved by technology

In the plug-in structure, due to the need to include the substrate for the touch sensor and the need to add optical glue between the touch sensor and the flexible cover, the thickness of the flexible OLED display is relatively large, which is not conducive to thin and light design, and Since the prepared touch sensor and the flexible cover need to be bonded together through optical glue, and then the touch sensor and the flexible OLED are bonded together through optical glue, the preparation process is cumbersome; -In the cell structure, when the touch sensor is prepared on the packaging material of the flexible OLED, it will inevitably affect the flexible OLED and reduce the yield of the flexible OLED display
