Abstract
A switchable window includes: first and second substrates (e.g., glass substrates); a liquid crystal inclusive layer (e.g., PDLC layer) disposed between at least the first and the second substrates; and a low-E coating provided between at least the liquid crystal inclusive layer and the first substrate. Voltage is applied to the liquid crystal inclusive layer via the low-E coating and a substantially transparent conductive coating which are on opposite sides of the liquid crystal inclusive layer. By adjusting voltage applied to at least part of the liquid crystal inclusive layer, the window is selectively switchable between at least first and second states with different visible light transmissions.
