Industrial tablet computers are divided into touch screens and non-touch screens, and the touch methods are divided into resistive touch and capacitive touch. Some customers will ask what is the difference between the two when consulting, and how to choose? Today, I will introduce the advantages and disadvantages of resistive screen and capacitive screen and the conditions of each adaptation.
Advantages of using capacitive screens in industrial tablet computers:
1. Multi-point touch is possible.
2. High positioning accuracy.
Disadvantages of capacitive screen in industrial control:
1. The operating workers in the industrial control industry generally wear gloves, and it is obviously not suitable to frequently take off the gloves to operate the capacitive screen.
2. Capacitive screens are more susceptible to temperature, humidity, electromagnetic interference and other environments, which is obviously not suitable for industrial control where the working environment is relatively harsh.
3. Capacitive screens are relatively expensive at present, especially for capacitive screens that support features such as multi-touch, the price is still a lot more expensive.
Advantages of using resistive screens in industrial tablet PCs:
1. The cost is cheap and the sensitivity is also very good.
2. It can adapt to various harsh environments, and can operate industrial panel computers with anything.
Disadvantages of resistive screen in industrial control:
1. The screen is easy to turn yellow
2. The light transmittance of the screen is not as good as that of the capacitive screen
3. The soft screen needs a certain amount of deformation. For those occasions that are easy to touch, it is easy to break the screen. The surface of the capacitive screen is said to have a very strong material that can support a certain amount of hammering without any problem.
So is it better to choose a capacitive screen or a resistive screen?
When choosing a suitable industrial LCD screen and industrial touch screen, it needs to be decided according to the application environment of the product, the application population and the product market. The choice between capacitive touch screens and resistive touch screens is usually determined by aspects such as cost, accuracy, damage resistance, and environmental adaptability.
