What is PCAP touch screen? 

I think many people are no longer strangers anymore. It should have been living in our various places. In recent years, many industrial equipment has also transitioned from resistive touch screens to projected capacitive touch screens. Although the reliability of the resistive touch screen and whether you touch it with your fingers or wearing gloves, its response ability is very sensitive. So, it has always been the first choice for most touch screen control of industrial equipment. Due to the development of technology, the projected capacitive touch screen has better optical clarity and scratch resistance, and now it can support all kinds of glove touch, or touch with water, etc. It is now also the first choice for touch screen solutions in industrial environments.

 

What is a Resistive Touch Screen?

In the past, most industrial control systems used resistive touch screens. Its main working principle is that two transparent layers are separated by a thin gap with a gasket. There is a conductive coating on the inside of each layer. When it encounters pressure squeeze, it will start the voltage to pass, so it can activate the contact point. It mainly uses pressure to make the touch screen work, unlike capacitive touch screens, it through the electrical characteristics of the capacitance to work.

But the resistive touch screen has several disadvantages:

  - Usually only supports single touch
  - Lack of optical clarity
  - Easy to be scratched by tools
  - Can be worn over time in overused places
  - Due to the economic scale, sizes larger than 24 inches are not available
  
Since PCAP Touch screen has many advantages, people deeply loved it. For example, PCAP Touch screen mainly uses glass, which has high optical clarity, and has begun to apply in medical product.
 
In recent years, with the development of science and technology, the latest PCAP Touch Screen has matured. It overcomes the challenges brought by thick gloves and harsh operating environments. Regardless of the IC controller, driver and firmware, there are great breakthroughs. The performance and accuracy of the capacitive touch screen have also risen to a level. It is estimated that in the future development, many resistive touch screens will be replaced by the latest PCAP Touch screen technology. I believe it will make our lives more and more convenient.
