Capacitive Touchscreen

Capacitive Touch Screen solutions

In September 2011 Danielson launched the new product Projected Capacitive Touchscreen (PCAP). The PCAP technology from Danielson enables a touch to be sensed through a protective layer in front of a display, allowing touch screens to be installed behind glass covers or vandal resistant glass.

PCAP from Danielson consists of a customized outer glass layer with a specialized sensor and a controller chip.

Danielson designs the solution to meet your requirements. Danielson can not only develop the complete system to resist scratches, impacts, vandalism and dusty environments, but also to resist harsh cleaning fluids. The solid state touch screen and controller provide high levels of reliability and longer life expectancy. This results in a drift free response and a low maintenance unit that requires no recalibration.

Benefits PCAP

• Multi-touch
• High optical transparency and visibility
• Durability
• Low maintenance
• No recalibration
• Easy to clean
• Requires low activation force

Cover lens options

• Polyester
• Glass
• Polycarbonate

PCAP controller

The interface between a Danielson PCAP touch sensor and your application is done by the PCAP controller. This controller continually scans and monitors the capacitance of the electrodes. When your finger touches the surface of the cover it increases the capacity of the underlying electrode. By using complex algorithms the controller can determine the exact location of your touch.

Specialists at Danielson will adapt the controller software settings for your application to assure a perfect execution of your total solution. The controller communicates with your PC system directly through USB interfacing, offering a superior sensitivity, accuracy and user experience. The touch panel driver can fully replace the mouse and supports operation systems like Windows, Linux, Mac and QNX.
