TSITouch of the US has registered a patent (#9,671,824) for a protective glass design for video walls that avoids the need to bond displays. The Glass Retention Bezel System (GRBS) is a modular solution that allows protective glass (clear, anti-reflective, and anti-glare) to be mounted directly on each video wall display, providing protection to the OEM bezel and display panel. In the event of a monitor failure, the GRBS can easily be removed, avoiding any issues associated with servicing a bonded display.
The GRBS consists of four precision machined metal bezels, 1/8” thick tempered cover glass, and all mounting screws (per display). Each kit is custom designed to be a perfect fit for each make and model of display. The GRBS does NOT block any of the viewable display and does NOT interfere with any interactive technology.
There’s a video online here showing that the technology can protect displays without the limitations of bonding. Of course, using a separate glass cover doesn’t deliver the visual performance benefits of bonded displays. (BR)
