German company Woehburk offers technology to give glass the ability to act as a rear projection
The material is as transparent as regular laminated sheet glass. Therefore the glass is not noticeable as a multimedia screen when not in usage. If a projector is pointing at the screen the glass turns into a visual screen that can display multimedia content.
The Woehburk CristalLine screens are available in several sizes up to 135 inches.
The Woehburk transparent screens are implemented into Digital Signage networks, retail application, and architectural glass projects. The holographic effect that arises from the transparency makes the CristalLine also suitable for special 3D effects on trade fairs and events.
The transparent screen technology is based on a specially developed layer. 1st the layer is optically activated by a laser in order to form a special surface structure. 2nd in vacuum particles are added which create a shell and through ionization they align on the structure. The material is laminated between two glass sheets and has no visible structure or Moiré pattern that can disrupt the picture.
Also the resolution of the screens exceeds HD by far, so in combination with a high resolution projectors can create new visual experiences.
