Home Appliances (Optical Shutter)

Citala's optical shutters, seen here embedded in the glass door of a high-end wine and beverage cooler, add a "wow factor" and utility to home appliances. At the flip of a switch, this door turns from translucent black to transparent, enabling users to see their inventory of drinks without disturbing the temperature balance within the cooler by opening its door.

It's a high-tech and highly efficient now you see it - now you don't effect, made possible by Citala's APD^TM technology with Onyx^TM, uniquely encapsulated particles sandwiched between paper thin layers of flexible substrate. Upon exposure to voltage, Onyx^TM particles align, allowing the efficient passage of light. When the voltage is turned off, the Onyx^TM particles return to an unaligned position, and the APD^TM panel (in this case, an appliance door) turns dark again.
