Multi-touch projected capacitive touch screens set with rugged durability
April 12, 2012 // Julien Happich
Dawar's new multi-touch projected capacitive touch screen technology provides the optimum combination of functionality, sensitivity and advanced optics in an all-glass solution suitable for medical, instrumentation and industrial applications.
The 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. The company’s PCT system provides optics with 90% light transmission, clarity of over 97%, a rapid response, and excellent accuracy (no linearity calibration required). The rugged all-glass construction delivers exceptional surface durability of over 9H pencil hardness and dependable performance over a wide operating temperature range.
The new PCT screens are available in a range of standard sizes from 4.3” to 24” diagonal for controller board solutions and 4.3” to 17” diagonal for Chip-on-Flex. The screens are offered 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).
