Abstract

The invention relates to a flexible projected capacitive touch screen and a manufacturing method thereof. The flexible projected capacitive touch screen comprises a display screen and a flexible circuit board, wherein silver nanowire-graphene composite electrode layers are arranged on two surfaces of the flexible circuit board; one surface of the flexible circuit board is connected with the display screen through a first adhesive layer; the other surface of the flexible circuit board is connected with a mask layer through a second adhesive layer; and a flexible hard film layer is arranged on one surface, deviating from the second adhesive layer, of the mask layer. By adopting flexible structures such as the flexible circuit board, the flexible hard film layer and the like, the touch screen can be flexibly bent; the characteristics of hard substrate display and flexible display are considered; and the manufactured flexible projected capacitive touch screen has the advantages of flexibility, scratch resistance, wear resistance, difficult breaking and accurate touch.

Description

technical field [0001] The invention relates to the field of display technology, and more specifically, to a flexible projected capacitive touch screen and a manufacturing method thereof. Background technique [0002] In terms of touch screen technology, projected capacitive touch screen technology is currently the mainstream in the market. There are three main structures: ITO (DITO) coating on both sides of the glass, two layers of ITO (SITO) coating on the upper surface of the glass, and ITO coating on a flexible film (single-layer FILM). The above structures are basically developed based on hard substrates. On non-flexible displays. [0003] Indium tin oxide (ITO) transparent conductive film has become the most important touch layer material for display screens such as non-curved LCD and OLED due to many reasons such as good light transmission, low thickness, excellent conductivity, and mature manufacturing process. The "indium" in ITO is a rare metal with high cost and...
