Innolux, a Taiwan based display manufacturer, engaged Zytronic PLC to achieve a tactile solution for its rugged touch displays designed for self-service kiosks and other public displays, according to a press release.

The Innolux concept incorporates a 13-inch customized ZyBrid multitouch sensor with precision-engineered 3D surface features machined in the 4mm thick toughened glass to guide the user's fingertips to the appropriate position on the screen. Zytronic's ZXY50 controller delivers the multitouch functionality and supports complex gestures, including contactless "hover" touch plus palm rejection, high noise immunity and millisecond fast speed of operation.

On the surface of the touchscreen, using its 5-axis computer numeric controlled glass machining equipment, Zytronic machined precise, "dimples," grooves and a dial into the glass. Precision machining the tactile finger guides into the glass surface, rather than drilling through and mounting physical dials, buttons and sliders, made it easier to create a waterproof, hygienic user interface with fewer exposed moving parts.
