With the rapid development of technology, touch screens are easy to operate, responsive, durable and durable. More and more fields begin to use touch screens as operating panels. The touch screen has only appeared in the Chinese market for just a few years. It has not been contacted and understood by many people. In fact, the touch screen is a device that transforms multimedia information and control. It gives multimedia a new look, and it greatly simplifies application operations. Even a person who knows nothing about electronic devices. It can still be operated on the touch screen. At present, there are two main types of common touch screens: resistive touch screens and Capacitive Touchscreens Overlay Each type of touch screen has its own advantages and disadvantages. Today we will take a look at the advantages and disadvantages of these two touch screens.
The first is that its cost and control system are relatively cheap, and the response speed is very good. And they are a kind of working environment completely isolated from the outside world, not afraid of dust and water vapor. Can adapt to various harsh environments. It can be touched with any object and has good stability.
The resistive touch screen can be designed as multi-touch. So when two points are pressed at the same time, the pressure on the screen becomes unbalanced. Causes errors on the touch screen. So multi-touch is more difficult to implement.
Capacitive Touchscreens Overlay only need touch, not pressure to generate signals. And it only needs one time or no calibration at all after production. The resistance technology requires routine calibration. At the same time, the service life of the capacitive touch screen will be longer. The capacitive touch screen also supports multi-touch technology.
In wet weather, when a large area of the palm or hand-held conductive object is close to the capacitive touch screen. Rather than touching, it may cause the capacitive screen to malfunction.
