Atmel and Corning Collaborate on Touchscreens with Multi-touch Functionality

Smartphone glass manufacturer Corning and Atmel are collaborating to develop ultra thin capacitive touchscreens with an expected superior multi touch performance.
This collaboration combines Atmel XSense flexible touch sensors with 0.4mm Corning Gorilla Glass. Together, they are claimed to deliver outstanding capacitive touch performance through thinner flat or curved cover glass.
Additionally, the circuit design of XSense enables narrower device borders, allowing for a more optimal viewing area. The combination enables industrial designers to create multi-touch devices with sleeker, lighter, and more contemporary touch interfaces without sacrificing reliability or performance.
Touch modules using cover glass thinner than 0.5 mm with relatively low conductive materials and non-optimal microcontrollers have been difficult to implement due to low signal-to-noise ratio (SNR) and aliased touch events, resulting in unsatisfactory multi-touch performance. XSense, combined with 0.4mm or curved Corning Gorilla Glass, enables multi-touch sensor panels that are thin, light, and damage-resistant.
"Our collaboration with Atmel accelerates the move toward thinner cover glass and enables the use of curved touchscreens for our customers designing next-generation applications," said James Nagel, division vice president, Program Development, Corning Gorilla Glass, Corning Specialty Materials.
A sample device that pairs Atmel XSenseŽ flexible touch sensors with 0.4mm Gorilla Glass will be on display at Computex Taipei in Taiwan.
