How can projected capacitive touch screens achieve a smooth response?

Modern shopping malls and supermarkets are already equipped with self-service checkout machines. A sensitive self-service checkout machine can effectively improve checkout efficiency and reduce queuing time. In many applications, the response speed and sensitivity of projected capacitive touch screens play an important role in improving efficiency and reducing operation time, thereby affecting the user's experience.
 

As the core indicator of touch technology, sensitivity is a precise technical game behind it. However, being too sensitive can lead to accidental touches, while not being sensitive enough can affect the user experience. So, how to find the perfect balance between preventing accidental touches and responding quickly? Engineers from Xinlilai Touch have provided the answer with fifteen years of experience.
 

Traditional touch screens often face problems such as "click delay" or "jumping points", which are caused by uneven conductive layers or signal interference. Our solution starts from the material source, using imported indium tin oxide (ITO) conductive film, and controlling the film thickness error within ± 3% through magnetron sputtering process. This nanoscale precision improves the efficiency of touch signal transmission by 40%, and even when operating with gloves, the projected capacitive touch screens can accurately capture a 0.5mm displacement of the touch point.
 

At the algorithmic level, the technique of "dynamic threshold calibration" has become crucial. projected capacitive touch screens devices will monitor real-time changes in environmental temperature and humidity, and automatically adjust signal trigger thresholds. In the cold chain warehouse test in the northern winter (-20 ℃), ordinary screens may experience contact drift, while our capacitive touch screen still maintains a response speed of 3ms. For interferences such as oil and water stains, the algorithm can intelligently filter them through waveform analysis, reducing the false alarm rate to 0.03%.
 

High sensitivity and fast response touch screen devices are the preferred choice for many people who pursue efficiency and user experience. We at Xinlilai are committed to providing customers with high-quality and high-sensitivity projected capacitive touch screens, and our experienced engineering and technical team provides technical support.
