Abstract

An electro-optical glazing structure having reflection and transparent modes of operation for selectively reflecting and transmitting electromagnetic radiation without absorption, respectively. The electro-optical glazing structure comprising: an electro-optical panel having first and second optical states of operation; a composite broad-band infrared (IR) reflective polarizing filter structure of electrically-passive construction, mounted to the electro-optical panel; and an optical state switching mechanism for switching the electro-optical panel to the first optical state of operation in order to induce the electro-optical glazing structure into the reflection mode of operation, and for switching the electro-optical panel to the second optical state of operation in order to induce the electro-optical glazing structure into the transparent mode of operation. When the electro-optical panel is switched to the first optical state of operation, electromagnetic radiation within a first prespecified bandwidth falling incident upon the electro-optical panel is reflected from the electro-optical panel without absorption. When the electro-optical panel is switched to the second optical state of operation, electromagnetic radiation within a second prespecified bandwidth falling incident upon the electro-optical panel is transmitted through the electro-optical panel without absorption. By virtue of the present invention, the glazing structure is capable of providing both thermal insulation as well as privacy functions.
