Abstract:
1. A glazing structure, comprising: a first substrate; a second substrate; a layer of an electrically controllable optically active material positioned between the first substrate and the second substrate, wherein the electrically controllable optically active material has a light transmissive state and a light reflective state; a pair of absorptive polarization layers positioned in between the first substrate and the second substrate; and a pair of reflective polarization layers having inner facing surfaces positioned in between the pair of absorptive polarization layers, wherein the glazing structure is transmissive and substantially non-reflective to light when the electrically controllable optically active material is in the light transmissive state; and wherein the glazing structure is substantially reflective to light when the electrically controllable optically active material is in the light reflective state.
