Video wall supports multi-touch transition between screen tiles: Page 2 of 2

Zytronic has developed a video wall demonstrator consisting of four multi-touch screens that are innovatively linked to enable seamless touch transition between screen tiles.

Each zero-border ZyBrid screen is supported by its own ZYX500 multi-touch controller, which outputs to a single master controller. Zytronic has created new, proprietary firmware for the master ZXY500, which combines the data from the individual controllers, ‘stitching’ them together, and then presenting a set of x-y co-ordinates to the host computer as a HID plug and play touchscreen device. Instead of individual touchscreens, the computer ‘sees’ one giant touch sensor. This innovative approach solves the problem of touch co-ordinates being dropped as a user passes their fingers from one screen to an adjacent unit to achieve a seamless transfer ‘handshake’ - no matter how many people are interacting on the video wall. The individual screens can be tiled, and multiple touch controllers linked to create huge, near-borderless interactive walls, with each thermally toughened glass touch sensor providing durable, vandal-resistant protection for the fragile displays beneath.

For this solution, Zytronic collaborated closely with TSItouch and their EMEA partner, Displaylite, to utilise their patented Glass Retention Bezel System (GRBS) to attach each zero-bezel 55” ZyBrid touch sensor to the 55” ultra-narrow border displays, in an incredibly slim frame maintaining millimetres wide spacing between the screens.
