PCAP Touchscreens are definitely one of the key technologies of the digital age, making possible a digital nation for many services. As the demand for touchscreens continues to grow, consumers are more likely to use projected capacitive touchscreens (PCAP), the most popular type of touchscreen, during the workday and even during leisure time.
One of the biggest advantages of PCAP screens is that they are built to last. Touchscreens used for industrial applications are likely to experience heavy use. Carefully selected and designed capacitive touchscreens will never suffer from problems such as dirt or fingerprint smudging. Note that this type of touchscreen does not have any rugged coatings or moving parts - which is why projected capacitive touchscreens should last for the entire life of the device or system. This is especially true if you work with an expert who knows how to design it so that the touchscreen meets the application requirements well.
In the unlikely event that a user scratches the surface of a capacitive touchscreen, it will continue to work properly. The only question is whether the rear conduction matrix is damaged. Otherwise, the touchscreen will continue to measure changes in the resulting electric field without noting damage.
One of the main reasons for the popularity of this technology is that it provides highly sensitive touch sensing. But this type of screen will only respond to a bare finger or conductive stylus. This is why the possibility of accidental input is minimal and the requirement for conductivity successfully limits the sensitivity of touch screens. In contrast to resistive touchscreens, which require more pressure, capacitive touchscreens can be activated with the lightest of touches.
PCAP technology offers very high contrast, high transparency and an excellent visual experience. It also offers higher light transmission than other technologies, making it ideal for highly bright environments.
Electromagnetic interference (EMI) noise can interfere with the accurate detection of touch events. To maintain the accuracy of touch detection, the PCAP controller utilizes firmware and hardware to avoid noise interference at different frequency bandwidths.
In some applications, the threat of water leakage or from other liquids can trigger a false touch. To avoid this, PCAP technology uses waterproof surfaces and firmware algorithms to distinguish between touches from fingers, styluses, gloves, or droplets. These features enable readability and unparalleled protection under the most challenging operating conditions.
