Glass media: ambition achieved

Illumination Physics has commercialised a practical LED product that can transform Vision Glass into a Media Wall and still maintain a very high degree of transparency when viewed from the inside.

IP Glass Media is a unique LED media product designed to be applied on the inside of the vision glass panels of a building so that the external architecture is unaffected. It is composed of a linear LED strip just 12mm wide and attached to the inside of the glass with a special 3M adhesive that has a service life of more than a decade.

This allows applications that apply LED technology to transparent glass so that it can become an integrated display, using the envelope of a building itself.

We have seen very low power LED and transparent circuitry laminated between two panes of glass; but while a composite product like this may be suitable for indoor use, the limitations in the LED laminating process mean that commercial structural glass panels have not been produced for building facades.

Even if that limitation could be overcome, the LED is not bright enough; and, fatally, if the LED fails, the entire pane of glass would have to be replaced – not a prospect the owner of a commercial building would entertain.

We have seen LED in linear format, installed in-between the two panes that make up double-glazing panels, referred to as ‘integrated glass units’ (IGUs). The brightness issue can be solved, but the problem of maintainability remains – a failure of any of the integrated LED requires that the entire IGU must be replaced.

Glass Media solves these issues. Unlike its precursors, illumination Physics’ Glass Media can be easily serviced and has no impact on the building envelope.

Custom lengths are produced to suit each application perfectly. The interval between Glass Media strips can also be varied infinitely, depending on the typical viewing distance and hence the resolution required.

A recent project for HSBC in Hong Kong (above) delivers a media wall system that would be integrated into the glass facades between the refuge floors. The height of the glazed zones varies from five to seven floors. Three zones were chosen, producing three large media walls which range from 880 square metres to 1,100.

This made use of strips placed at 200mm centres, the perfect horizontal pitch for typical viewing at distances from 100m to 4km. Transparency from within the building remained at 95 percent, yet from the outside the media walls are all but invisible.

The three media walls can be used as one or as three separate but synchronised images that relate to one another to convey a singular idea. Importantly, the façade lighting which surrounds the screens has also been synchronised with the video content and it was this mix of the two mediums that provided a wonderful challenge.

illumination Physics offers content creation for animated displays or content management as required so that the display is optimised.
