Flexible cover plate, preparation method thereof and flexible OLED display screen

Abstract

The invention discloses a flexible cover plate, a preparation method thereof and a flexible OLED display screen. The flexible cover plate comprises a transparent base material, a hardening layer located on the upper surface of the transparent base material, an isolating layer located on the lower surface of the transparent base material and a shielding layer located at the edge of the lower surface of the isolating layer, and further comprises a touch layer located in an area defined by the shielding layer and making contact with the lower surface of the isolating layer, and a binding area isarranged in the shielding layer. According to the technical scheme disclosed by the invention, the touch layer is integrated on the flexible cover plate, so that the flexible cover plate has a touch function, the thickness of the flexible OLED display screen is reduced, the light and thin design of the flexible OLED display screen is realized, and the preparation process of the flexible OLED display screen is simplified. In addition, the touch layer is integrated on the flexible cover plate, so that the influence on the flexible OLED due to the operation on the packaging material of the flexible OLED can be reduced, and the yield of the flexible OLED display screen can be improved.

Description

technical field [0001] The invention relates to the technical field of display screens, and more specifically, to a flexible cover plate, a preparation method thereof, and a flexible OLED display screen. 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 th...

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 relatively cumbersome; and In the on-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.
