Large Format Zytronic Multi-Touch Screens Incorporated Into DisplayLite Touch Table
The new Zytronic DisplayLite products are targeted at showrooms, boardrooms, banks and other business, retail and leisure environments. One of its key features is an attractive smooth, all glass fronted design, free of unsightly bezel structures or frames around the perimeter of the display. Supporting Windows 8 operation, it is based on NEC’s super-slim MultiSync X462S LED display. The tables and wall-mounted displays have the capability to detect more than 10 touch points at once. This allows multiple users to simultaneously activate the surface using swipes, drag/drops, page flicks, pinch zooms and a variety of other defined gestures.
The initial touch solution provided to DisplayLite by Zytronic consists of 40, 46 and 55-inch versions of the company’s multi-touch projected capacitance based touch sensor made from 4mm thermally toughened glass with a custom printed black border. This is combined with Zytronic’s ZXY200 high performance multi-touch controller which interfaces directly with Windows 7, 8 and the latest Linux kernels supporting multi-touch. The inherent ruggedness of Zytronic’s multi-touch sensing solutions makes them highly suited to public use and self-service deployments. Thanks to their unique construction, they have strong resilience to severe impacts, scratches, liquid spillages and harsh cleaning chemicals.
Many large format multi-touch solutions on the market lack the sturdiness required for reliable use in demanding operational environments. Systems based on camera or infrared (IR) touch technologies require bezels for housing the transmitting/receiving optics. This makes edge-to-edge operation difficult. Such solutions have poor aesthetics and are vulnerable to damage, with performance potentially affected by the congregation of dust/dirt around the bezel optics. Furthermore, the risk of false touches is an ever present problem with camera/IR based touch solutions — especially when deployed horizontally into tables, as users may inadvertently activate the touchscreen while leaning across or resting upon the table, or bring other items (ties, sleeves, pens, cups, etc.) accidentally into proximity with its surface. According to the company, Zytronic’s multi-touch technology eradicates these issues, as it will not react to inanimate or non-conductive items and advanced ‘palm rejection’ firmware, embedded in the touch controller, detects and ignores false touches from arms, elbows, etc.
