A lot of companies are working on larger panel touchscreens with a lot of functionality—multi-gesturing, robust in kiosks, gaming and ATMs.”
DuPont Display Enhancements (Torrance, Calif.) has been producing optical bonding through its Vertak™ technology for more than a decade. The technology provides improved performance, especially in sunlight readable displays. In March, DuPont and Ocular signed a licensing agreement.
“It was originally developed for bonding protective glass sheets for outdoor kiosk applications,” Mozdzyn says. “We use that process but have interest in developing it in touch panel processes as we go into larger and larger capacitive touchscreens.”
For example, the use of projected capacitive is allowing more advanced functionality. Original touchscreen use was a single-touch application to a big area with low resolution. That profile, Mozdzyn says, is changing rapidly. Now there is gesture support, single-finger, two-finger and multi-touch functionality.
ON THE ROAD
Touchscreens are making their way into the automotive market. One of the more innovative approaches is from Digital Dash (Hamilton, Ontario, Canada). Using what it calls Reconfigurable Tactile Display (RTD), Digital Dash’s multifunctional solution uses familiar physical controls like knobs, buttons and sliders, with touch input, while remaining totally reconfigurable in software. The functionality, says President Tim Pryor, allows the RTD to reduce driver distraction and remain intuitive.
