Capacitive touch screens are leading the way in the display industry and are a favorite in mobile phones and tablets. The ability to scroll, zoom, and pinch delivers a user experience that resistive touch screens simply can't compete with.
In recent years, capacitive touch technology has also made significant advances in industrial applications. However, unlike consumer products, industrial displays often operate in more demanding and rugged environments, putting the performance of these screens to the test. At Displaystouch, we design and manufacture capacitive screens with a robust G+G (Glass-Glass) structure, providing superior stability that is ideal for industrial use. Our cover lenses are primarily made of glass, ensuring both durability and excellent clarity. To learn more about our cover lens options, click here.
Capacitive Touch Controllers The capacitive touch controller is key to achieving the functionality you desire. Consumer-grade controllers typically have a short lifecycle and are frequently optimized for cost, leading to redesigns or discontinuations as market demands change—often within just 2-3 years. In contrast, industrial capacitive touch controllers focus on robust performance and longevity, with certain driver ICs available for 10 years or longer without any changes. This longevity is what industrial displays require, ensuring your product remains reliable without the need for frequent updates.
Anti-Interference Technology Capacitive screens operate by detecting changes in capacitance, which makes accurate capacitance values crucial. However, these values are susceptible to interference from various sources, including AC power supplies, motors, GSM antennas, induction chips, and stray signals. Such interferences can disrupt the coupling capacitance between RX and TX, leading to incorrect touch positioning, unresponsiveness, or even unintended activations. That’s why it’s essential for the touch driver IC to possess strong anti-interference capabilities, ensuring dependable performance across diverse conditions.
