Touch technology makes ultra-thin double-sided LCD interactive

18-07-2022 | Zytronic | Subs & Systems

Zytronic's Japanese partner and touch display integration specialist, DISIGN, has developed its infoverre super-thin, double-sided LCD unit into an interactive touchscreen module for a chain of Japanese drive-thru quick-service restaurants. The rugged and sleek units feature Zytronic's all-weather ZyBrid 15.6" multitouch sensors mounted directly in contact with the display's surface, and its proprietary ZXY500 projected capacitive controllers.

The display solution successfully mitigates light reflection, often occurring at the interface of layered substrates because of their different refractive indices. With a traditional touchscreen system, reflection can happen on the front and back of the touch sensor and from the display surface. Still, with the innovative structure, reflection only occurs from the surface of the cover glass or touch sensor, notably improving visibility. This can be enhanced further by using anti-glare or anti-reflective treatments.

"The infoverre product has been successfully deployed in public buildings, railway stations, and retail outlets for information signage, but making them interactive opens up a whole new world of self-service possibilities," explains Yan Takatani, president of DISIGN. "Our knowledge of attaching the protective glass directly onto the display was a perfect match for using Zytronic's highly reliable glass touch sensors."

One of the unique features of Zytronic's projected capacitive technology (PCT and MPCT) is its capacity to accurately respond to touch, even when the user wears thick gloves while remaining unaffected by rainwater or dirt on the screen surface. An extra benefit for the user and operator is that the flat, all-glass surface of the kiosk's screen is extremely easy to clean.

"There may be other double-sided signage products on the market, but few are interactive, and even fewer are so thin, and I believe none can display 'true black' even in bright sunlight with such a wide viewing angle," adds Takatani san. "We are delighted with the launch of our interactive infoverre product and, thanks to Zytronic's proven, rugged and reliable touch sensors, we can assure QSR and other operators of self-service kiosks that they will save costs further down the line, both in terms of reduced maintenance, power consumption and loss in revenue."
