电容屏原理//////

电容屏幕表面镀有导电 ITO 层,四角连接电压信号,电荷分布于屏幕表面,形成均匀

电场,当手指触摸在金属层上时,由于人体电场,用户和触摸屏表面形成以一个耦合电容 ,

对于高频电流来说,电容是直接导体,于是手指从接触点吸走一个很小的电流。这个电流分

从触摸屏的四角上的电极中流出,并且流经这四个电极的电流与手指到四角的距离成正比 ,

控制器通过对这四个电流比例的精确计算,得出触摸点的位置。

CTP(Capacitive touch panel) is a piece of consists special material, as ITO

coating to realize the function of touch .There is electrode pattern printed along the

edges distributes a low voltage field over the conductive layer. When a finger touches

the screen and draws a minute amount of current to the point of contact, creating a

voltage drop. The current flow from each corner is proportional to the distance to the

touch point. The location of the point of contact is calculated by the controller and

transmitted to the computer.

电容屏结构/ / / / 

目前市场上的电容屏产品根据其材质差异可分为 G/G,G/F,P/G,OGS 等结构,泰奇克光

电电容屏产品目前主要以 G/G 结构为主。

At present, the CTP products on the market according to the difference of the

material can be divided into G/G, G/F, P/G, OGS structure, TouchKit photoelectric

CTP is mainly based on G/G structure.

电容屏优点

1,电容触摸屏耐磨损、使用寿命长、维护成本低。Wear Resistance、Long service life and

low maintenance costs

2,电容触摸屏触摸精度高,且只需要一次或者完全不需要校准。High accuracy, needs only

one or no need to be calibrated
