3.0 Switch Glass

Switch Glass is composed by two polyester layers coated by a conducive layer in the internal surfaces. Between the two polyester layers there is a layer of liquid crystals scattered in a polymeric solid matrix.

When the film is in the OFF state, the liquid crystals are not aligned and look through is prevented, thus light can still pass through the glass. When Switch Glass is switched ON, liquid crystals align, turning the glass transparent. This changing of state takes place within milliseconds. Switch Glass is thought for indoor applications: division of ambients, display cases, residentials windows, rear projection screens.
