Title:
SWITCHABLE ONE-WAY MIRROR
Document Type and Number:
WIPO Patent Application WO/2019/140035
Kind Code:
A1
Abstract:
A switchable one-way mirror device dividing first and second spaces includes a switchable electro-optic layer facing the second space and configured to be electronically switchable between a transmissive state and one or more opaque states, and a partial reflector incorporated within or adjacent the switchable electro-optic layer and facing the first space and configured to partially reflect light. The switchable one-way mirror partially transmits a first light going from the first space to the second space, and a second light going from the second space to the first space. When the switchable electro-optic layer is in an opaque state, transmission of light through the device is reduced thereby changing the ratio between the transmission of the second light to the first space and the reflection of the first light by the partial reflector resulting in reduced visibility of the second space by a viewer in the first space.
