Durable Multi-Touch Projected Capacitive Touch screens offer enhanced sensitivity

April 12, 2012 // By Paul Buckley
Dawar's new Multi-Touch Projected Capacitive Touch (PCT) Screen technology claims to provide the optimum combination of functionality, sensitivity and advanced optics in an all-glass solution ideal for medical, instrumentation and industrial applications.

Dawar’s new multi-touch PCT screens presently support four simultaneous touch points with full gesture support – tap, flick, pinch, click, expand and rotate.  Input is effortless with finger, glove or conductive stylus.  Dawar’s PCT system provides optics with 90% light transmission, clarity of ≥ 97%, a rapid response, and excellent accuracy (no linearity calibration required).  The rugged all-glass construction delivers exceptional surface durability of ≥ 9H pencil hardness and dependable performance over a wide operating temperature range.

The new PCT screens are available in a range of standard sizes – 4.3 to 24 inch diagonal for controller board solutions and 4.3 to 17 inch diagonal for Chip-on-Flex.  Dawar offers screens in both standard (4:3) and wide aspect ratios, and can provide custom features such as a decorative front lens for the popular tablet PC look. 

All are Windows 7 HID compliant – with drivers available for most other operating systems – and support multiple interfaces (USB, RS232 and I2C).  A range of Dawar controller boards, drivers, interface cables and other components are available in stock to provide a complete, one-source plug-and-play solution. In addition to its broad array of standard products, Dawar can provide a complete range of custom solutions.
