What is PCAP(projected capacitive) touch screen panel?
The PCAP(projected capacitive) touch screen panel is a control display that uses the conductive touch of a human finger or a specialized input device for input and control.Unlike some other techniques (resistive, infrared, surface wave, etc.) where the sensor is at the front and therefore more vulnerable, projected capacitance (PCAP) technology mounts the sensor foil behind a protective overlay, so that it does not has shortcomings of, for example, resistive touchscreens, which means that they are used in many high-quality and large-scale applications.
The PCAP touch screens have a superior multi-touch performance, durability, excellent optical transmittance(greater than 90%), scratch-resistance, free of aging symptoms, offer high performance in accuracy, power consumption and refresh rate.
The multi-finger touch input and gestures, enables significant improvements to the user interface. Popular gestures such as two-finger pinch and zoom let users zoom in or out on an image. With multi-touch we are able to develop custom gestures, which add value for end users and can be promoted as product differentiation
The advantages of industrial capacitive touch screen
High Sensitivity
Capacitive touch screen has very high sensitive by detect touch through electrostatic capacitance. Whether it's fingers, gloves, pens, etc., they can be easily triggered, and the response speed is very fast.
Easy calibration
Capacitive touch screen can be used with only one or no calibration required after production, while resistance technology requires routine calibration.
High Touch Accuracy
Touch panel of the capacitive touch screen can precisely detect the user's touch position, enhancing the user's control during fine operations on the screen. Additionally, capacitive touch screens support multi-touch, allowing users to perform actions such as rotation and zooming through touch gestures with their fingers.
Strong Anti-Interference Performance
Our capacitive touch screens mainly adopt industrial-grade chips such as Cypress/ILITEK, making them suitable for application in relatively complex industrial environments, including environments with electrical grid interference and servo motor disruptions.
Durable
The surface of capacitive touch screens is typically made of high-strength materials, effectively preventing scratches and fractures.
Lower Power Consumption
From the perspective of touch technology, capacitive technology excels over resistive technology in terms of light loss and system power consumption.

FAQ
Q: How does a capacitive touchscreen work?
When a capacitive panel is touched, it draws a small charge to the point of contact, becoming a functional capacitor. The change in the electrostatic field is measured to find the location. In some designs, circuits located at each corner of the panel calculate the charge and send the information to the controller for processing. In multitouchscreens, sensors are arranged in a grid to enable more complex input.
Q: How does a stylus work on a capacitive touchscreen?
Q: How to clean a capacitive touchscreen?
Follow these steps to clean a capacitive touchscreen:
Dampen a soft cloth or microfiber cloth with isopropyl alcohol or a mild nonabrasive soap and water solution, and then gently wipe the touchscreen clean.
Wipe the screen and edges dry.
Ensure the glass and screen edge are completely dry before using the device.
