The Chrominance touchscreen sensor works with the aXiom touchscreen controller and TouchNetix claims it is easy to integrate with displays for industrial, medical, transportation and military applications and is suitable for harsh and hazardous environments.
The sensor is capacitance based and provides 16bit x-y mapping of up to 10 concurrent touches. It also offers proximity detection to allow screen wake-up when the hand approaches the display. It also provides signals for low latency haptic feedback.
Because of the Chrominance modules’ high immunity to conducted and radiated interference – they are qualified to Class A according to the EN61000 standard Parts 4-6, 4-4 and 4-3 – they also maintain reliable performance in harsh operating conditions which often cause conventional displays to fail to recognise touches, or to report false touches.
The Chrominance assemblies are a range of standard touchscreen sensor modules for displays ranging in size from 4.3” to 24” (diagonal). Evaluation kits are available immediately for 12.1”, 15.6” and 21.5” displays.
A Chrominance module is supplied as a 0.7mm glass/ITO sensor hot-bonded to a flexible printed circuit tail and a TouchNetix aXiom controller board. TouchNetix can bond the module to a standard 3mm cover glass at the customer’s request.
TouchNetix provides reference drivers for the Windows and Linux operating systems, and for real-time operating systems used in embedded computing environments.
Chris Ard, managing director of TouchNetix, claims that Chrominance is the world's best touchscreen for harsh or hazardous applications.
