Abstract:
An electro-optical glazing structure having reflection and transparent modes of operation for selectively reflecting and transmitting electromagnetic radiation without absorption, respectively, said electro-optical glazing structure comprising:an electro-optical panel having first and second optical states of operation; a composite infrared (IR) reflective polarizing filter structure of electrically-passive construction, mounted to said electro-optical panel; and an optical state switching mechanism for switching said electro-optical panel to said first optical state of operation in order to induce said electro-optical glazing structure into said reflection mode of operation, and for switching said electro-optical panel to said second optical state of operation in order to induce said electro-optical glazing structure into said transparent mode of operation, wherein electromagnetic radiation within a first prespecified bandwidth falling incident upon said electro-optical panel is reflected from said electro-optical panel without absorption when said electro-optical panel is switched to said first optical state of operation, and wherein electromagnetic radiation within a second prespecified bandwidth falling incident upon said electro-optical panel is transmitted through said electro-optical panel without absorption when said electro-optical panel is switched to said second optical state of operation.
