Abstract
A controllable privacy structure, such as a window or door, may include an electrically controllable optically active material connected to a driver. The driver can control the application and/or removal of electrical energy to the optically active material to transition from a scattering state in which visibility through the structure is inhibited to a transparent state in which visibility through the structure is comparatively clear. The driver may need to be located in relatively close physical proximity to the privacy structure the driver is intended to control. Devices, systems, and techniques are described for discretely positioning a driver relative to a privacy structure to be controlled.
Claims20
A privacy door comprising:
- a first pane of transparent material;
- a second pane of transparent material;
- an electrically controllable optically active material positioned between the first pane of transparent material and the second pane of transparent material, the electrically controllable optically active material being further positioned between a first electrode layer and a second electrode layer;
- an optically opaque panel positioned across an external surface of the privacy door;
- and
- a driver positioned behind the optically opaque panel, the driver being electrically connected to the first electrode layer and the second electrode layer, the driver being further electrically connected to a power source and configured to condition power received from the power source to provide a drive signal to the first electrode layer and the second electrode layer for controlling the electrically controllable optically active material.
