High reliability, Cost effective, Widely applications To identify any |
contact media such as finger(with gloves or not) pen,credit card , |
etc of input signals Lead-out Device adopts FPC(Flexible Circuit |
panel materials) the small other resistance values and flexibility |
| fwell of PET material than manufacturers.Insulation point is small |
| of Lines,best visual effects, now we can do the smallest insulation |
| point is ¦µ0.03mm, far from leading with other manufacturers.There |
| have a variety of materials and processes to choice that bright face, |
| fog face, anti-reflection, extinction, prevention such as Newton's, |
| ring etc on the touch screen surface. |

4-Wire resistive touch screen is the preferred solution for low cost applications. It consists of a |
conductive bottom layer (ITO Glass or Film) and a conductive top layer (ITO Film). The two layers are |
suspended by many very small spacer dots. When a certain point is touched, the top layer contacts the |
bottom layer and a voltage charged by the controller is applied to the bottom layer¡¯s electrodes. The |
| coordinate X axis of the touch point can be detected by measuring the voltage the voltage value thru the |
| top ITO layer and the coordinate Y axis of the touch point can be detected in the same way by changing |
voltage input to the top layer's electrodes.¡¡ |
