Problems solved by technology

[0003] At present, most of the touch screen design traces are generally routed through the frame, and the traces are generally made of opaque metal materials (copper, silver glue, silver bromide or molybdenum lithium molybdenum, etc.), resulting in traces Lines cannot enter the window area of ​​the touch screen, which leads to the inability of the touch screen to achieve an ultra-high screen ratio of 90% to 100%. The screen ratio is the ratio of the area of ​​the window area to the area of ​​the entire touch screen.
In addition, in order to avoid affecting the user experience, it is usually necessary to add ink to block the metal traces of the touch screen frame, which may lead to higher material costs

Abstract

The invention discloses a transparent border touch screen and a preparation method thereof. The touch screen comprises a polymer film, the polymer film is provided with a first transparent touch layerand a second transparent touch layer in an attached mode; the second transparent touch layer and the first transparent touch layer are attached to different surfaces of the polymer film; each of thefirst transparent touch layer and the second transparent touch layer comprises a touch area and a wiring area; the touch area is provided with a touch graph circuit; the touch graphic circuit is provided with a receiving end or a transmitting end, the wiring area is annularly arranged on the periphery of the touch area and provided with a touch output circuit connected to the receiving end and thetransmitting end; the touch output circuit, the receiving end and the transmitting end are all made of transparent multi-element alloy, and all or part of the wiring area and the touch area jointly form a window area of the touch screen. According to the transparent border touch screen and the preparation method thereof provided by the embodiment of the invention, the transparent border routing design of the touch screen can be realized, so that all or part of the routing area and the touch area form the window area of the touch screen, and the screen-to-body ratio of the touch screen is improved.

Description

technical field [0001] The invention relates to the technical field of touch film, in particular to a transparent frame touch screen and a preparation method thereof. Background technique [0002] As a simple and convenient way of human-computer interaction, touch screen has been widely used in various fields of our daily life, such as mobile phones, car central control, tablet computers, media players, navigation systems, digital cameras, game equipment, monitors and medical equipment and other fields. [0003] At present, most of the touch screen design traces are generally routed through the frame, and the traces are generally made of opaque metal materials (copper, silver glue, silver bromide or molybdenum lithium molybdenum, etc.), resulting in traces Wires cannot enter the window area of ​​the touch screen, and thus the touch screen cannot achieve an ultra-high screen ratio of 90% to 100%, wherein the screen ratio is the ratio of the area of ​​the window area to the a...
