Heatable vehicle window with different voltages in different heatable zones

A heatable vehicle window comprising:

• first and second substrates laminated to one another via at least one interlayer;
• a coating including at least one heatable conductive layer supported by said first substrate,
• a first bus bar located across said coating from a plurality of bus bars so that at least part of a viewing area of the window to be heated is located between at least part of the first bus bar and respective portions of the plurality of bus bars, each of said bus bars being in electrical communication with said at least one conductive layer of the coating;
• and
• wherein first and second ones of said plurality of bus bars are used to simultaneously apply different voltages, respectively, across the at least one conductive layer in order to heat said at least one conductive layer.

A vehicle window comprising:

• a conductive layer supported by a substrate;
• wherein a first voltage V1 is applied across the conductive layer via first and second bus bars, and a second voltage V2 is applied across the conductive layer via said first bus bar and a third bus bar;
• and
• wherein the second bus bar is spaced further across said conductive layer from said first bus bar than is said third bus bar, and wherein V1>V2.
