Glass Turns Opaque With Electricity

Reveal switchable privacy glass uses a low voltage electrical current to arrange liquid crystal molecules into a pattern that makes glass transparent when turned on.

Glass turns opaque with electricity.

When electricity is applied to the film via the wiring the liquid crystals align and the glass instantly becomes clear. Is this a diy project possible.

How do you make glass that turns opaque with electric current. Retail applications include using the opaque state as an imagery glass rear projection screen surface on an exterior storefront. Apply a small voltage and it turns opaque blueish and dark. The transparent toilets turn frosted and opaque once locked.

A special film laminated between glass layers allows for instant privacy for any commercial or residential application. Here it s transparent and looks much like ordinary glass. Even though similar dimmable glass already exists this invention relies on completely new technology and if it s successfully scaled up we could soon kiss goodbye to ugly window shades. Electrochromic glass changes color under electric control.

Once you lock the door it triggers an electric current in the glass which turns frosted and opaque. Scientists have developed a brand new type of electronic window that can switch from transparent to opaque and back again in under one minute.

You can flip a switch and the glass walls go from transparent to opaque. Turned off the lc molecules revert to a random pattern diffusing the light and causing the glass to become opaque. Smart tint switchable electric films are designed to variably adjust light between a transparent and an opaque state with ac power. Our technology allows for instant privacy of windows on demand with the flick of a switch or the turn of a dimmer and is the next generation in switchable privacy glass as well as electronic dimmable window.
