What the difference of Capacitive Touch Screen and Resistive Touch Screen?
With the advancement of technology, touch technology has also undergone a process of gradual upgrading and development from low to high.
According to its working principle, it is generally divided into four types of touch screen: resistive touch screen, capacitive touch screen, infrared touch screen and surface acoustic wave touch screen.
Capacitive touch screens are quite different from traditional resistive touch screens.
When the resistive touch screen is working, only one touch point can be judged at a time. If the touch point is more than two, the correct judgment cannot be made, so the resistive touch screen is only suitable for click, drag and so on. The judgment of the action.
However, multi-touch of capacitive touch screen can divide the user's touch into two tasks: collecting multi-signal and judging signal meaning to complete the judgment of complex actions.
Capacitive Touch Screen VS Resistive

Resistive Touch Screen |
A multi-layer composite film. It consists of a layer of glass or plexiglass as the base layer, and the surface is coated with a transparent conductive layer (ITO film), which is covered with a hardened, non-slip plastic layer. | Can only judge one touch point at a time | Resistive touch screens are inexpensive and easy to produce. | It is easy to scratch and hurt, and its life is not long. |
| Capacitive Touch Screen | Double glazing: a transparent film layer is applied to the glass screen, and a protective glass is added to the conductor layer. | Multi-touch, more user-friendly, no need for button assist. | Fast response, higher resolution when the size is slightly larger, double-layer glass layer tuberculosis is more durable (scratch resistant, pollution) | The price cost is slightly higher than the resistive touch screen. |
