Abstract:
1. A window comprising: an inner substrate and an outer substrate, the inner and outer substrates being substantially parallel to one another; a multi-layer low-E ultraviolet (UV) blocking coating supported by an inner surface of the outer substrate, the low-E UV blocking coating blocking significant amounts of UV in the range of from about 380-400 nm; a liquid crystal inclusive layer disposed between at least the inner and outer substrates, the liquid crystal inclusive layer including liquid crystals whose alignment is dependent upon an electric field, one or more grooves or channels being formed in the liquid crystal inclusive layer so as to attenuate a z-component of compressive stress therein to below 100 MPa; first and second substantially transparent conductive layers, the first and second substantially transparent conductive layers being provided between the liquid crystal inclusive layer and the outer and inner substrates, respectively; first and second polymer inclusive laminating layers, the first laminating layer provided between at least the liquid crystal inclusive layer and the outer substrate and the second laminating layer provided between at least the liquid crystal inclusive layer and the inner substrate; at least one bus bar in electrical communication with at least one of the first and second transparent conductive layer(s) so as to cause the liquid crystal inclusive layer to become activated when a voltage is applied thereto; and wherein the multi-layer low-E UV blocking coating comprises at least one IR reflecting layer and at least one UV blocking layer so that no more than about 20% of ambient light having a wavelength of from 380-400 nm reaches the liquid crystal inclusive layer, and wherein the window has a visible transmission of at least about 55% when the liquid crystal inclusive layer is activated.
