Smart Glass is used in everyday products such as smartphones and premium or luxury vehicles. It is currently still neglected in architecture and buildings, even though so many functions would be feasible today. This new glass technology will be featured on the 23026 October at this year's edition of the Glasstec trade fair in Dusseldorf, Germany. Currently, engineers are developing smart glass to be used in the building sector. For example, wall-mounted switches and remote controls could be used so that users can select between transparent and non-transparent partition walls. Prof Dr U Knaack of TU Darmstadt said: "There are many interesting things under development including display glass and OLEDs." "As soon as we introduce these into the building skin, facades will become more active and will be able to contribute more to the function of the building." New lighting technology such as OLEDs (Organic light emitting diodes) is also being developed. Unlike conventional LEDs and all other light sources, OLEDs emit their light across the entire surface.
