    • 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.
    • 一种具有反射和透明工作模式的电光玻璃结构,分别用于选择性地反射和传输无吸收的电磁辐射。 该电光玻璃结构包括:具有第一和第二光学操作状态的电光面板; 一种电动被动结构的复合宽带红外(IR)反射型偏振滤光器结构,安装在电光面板上; 以及用于将电光学面板切换到第一光学状态的光学状态切换机构,以便将电光玻璃结构引入反射操作模式,并且将电光学面板切换到第二光学状态 的操作,以便将电光玻璃结构引入透明操作模式。 当电光面板切换到第一光学操作状态时,入射到电光面板的第一预定带宽内的电磁辐射从电光面板反射而不吸收。 当电光面板切换到第二光学操作状态时,入射在电光面板上的第二预定带宽内的电磁辐射通过电光面板传输而不吸收。 凭借本发明,玻璃窗结构能够提供隔热以及隐私功能。
