With the unusual characteristic of throwing the light forward through the glass, not reflecting it back as most other obscure or translucent glasses do, UMU switchable privacy glass panels are ideal for rear projection screens. The picture clarity of rear projection onto UMU is near perfect, with the added advantage of being able to switch it to a clear window.

This opens up a whole new concept with the use of display advertising, training rooms and video conference facilities. One technique is to use an UMU screen in translucent mode and project an image from behind the screen using a video or slide projector. If desired the screen can be switched to transparent mode at the same time as turning off the projector to reveal a display behind the glass screen.

UMU 瞬間切換調光玻璃之特性及優點
1.反應時間非常迅速且透明度可隨即改變:
由半透明轉換至透明,時間僅約1/1000秒,而由透明轉換至半透明可在1/100秒完成。快速的反應使UMU的應用範圍擴大,並可有其他變化運用。

2.可供應尺寸約可達900-2400mm:
藉由液晶板的開發,瞬間切換調光玻璃UMU,現已可以像一般玻璃尺寸一樣,達到900-2400mm之大小。這就是為什麼有許多在展示用途及建築方面的應用上可以考慮的原因之一。

3.耗電量低,符合經濟成本:
操作瞬間切換調光玻璃所需電量僅需3.5W/㎡,經濟效應遠比其它產品更為驚人,且不需特別維修,操作成本上也不會形成較大的負擔。

4.膠合玻璃的組合,更具安全性:
UMU玻璃的組成為膠合玻璃,其強韌而富粘著力的中間膜,可將兩片玻璃緊粘在一起而不易破碎,即使破裂,亦無玻璃碎片飛散的危險。

5.可配合使用各種電子信號的感應裝置:
因為電子訊號可持作UMU之調光切換,所以任何可轉換為電子訊號之感應裝置訊號皆可運用。這個理想已成功的使用在展示及建築上了
