1. An electro-optical glazing structure having reflection and transmission modes of operation for selectively reflecting and transmitting electromagnetic radiation, respectively, said electro-optical glazing structure comprising:
- an electro-optical glazing panel of laminated construction, having first and second optical states of operation, wherein said electro-optical glazing panel comprises at least one cholesteric liquid crystal (CLC) electromagnetic radiation polarizing panel, and wherein the CLC electromagnetic radiation polarizing panel comprises a CLC material with a non-linear distribution of the CLC throughout the electromagnetic radiation polarizing panel; and
optical state switching means for switching said electro-optical glazing 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 glazing panel to said second optical state of operation in order to induce said electro-optical glazing structure into said transmission mode of operation.
