II Types of Products :




4-wire touch panel

 

Xinhechang four-wire touch panel is suitable for small and medium-sized products, such as PDA, handheld systems and so on. The four-wire design theory is that the upper and lower layers of the X and Y axis lines are converted into coordinate values and displayed on the panel by the touch controller.


Five-line touch panel

The size of AMT five-wire touch panel is from 3 ”to 24”. Resistive five-wire can be used in different systems and environments. The design theory is that the lower layer is X and Y lines, and the upper layer is the induction layer.


Eight-line touch panel


Xinhechang eight-wire touch panel can be from 6 ”to 22”. The design theory is that the upper and lower layers are divided into X and Y axes, and an auxiliary line is added on each axis to assist the touch controller. Correct deviations and do double protection design. The biggest advantage of the eight-wire type is that it can maintain accurate linearity for a long time, especially for industrial use.



III Structure of Products :


structure

There are two types of standard 4, 5, and Xinhechang touch screen structures, one is a three-layer design and the other is a five-layer design.


Three-layer structure

The three-layer design is a commonly used structural design, which can have good light transmission. The bottom layer is made of ITO glass, and the top layer is made of ITO PET. The two conductive bodies are combined to form a touch panel .


Five-layer structure

The five-layer structure design generally uses a back plate of reinforced glass or PC, and the upper two layers are ITO PET, which combines the three types. The five-layer design is mainly designed for special products.


Surface  

The surface design of the AMT touch panel can be bright or matte, and has different surface specifications in different application areas.


Matte

The design with a matte surface is the requirement of most products. The biggest advantage is the anti-glare design with a scratch-resistant layer on the surface. The Xinhechang matte touch panel provides high-definition characteristics and is scratch-resistant deal with.


Glossy

 Xinhechang touch panel shiny products are provided according to customer requirements, with high definition and low haze.


Surface hardness

The surface hardness of AMT resistive touch panels is greater than 3H (pencil hardness specification). The latest surface glass touch panel (GFG) has a surface hardness that meets the Mohs hardness 5 specification. If the upper layer is an HD film, the surface hardness is 9H (pencil hardness specification).
