Abstract:
An apparatus for providing animated lighted areas on a surface comprising:a) a glass substrate having at least a first surface wherein the surface includes a substantially clear substantially conductive layer, and a second surface wherein the surface does not include a substantially clear substantially conductive layer; b) a polymer thick film phosphor ink layer applied to the substantially clear substantially conductive layer of the glass substrate; c) a polymer thick film dielectric layer applied to the phosphor ink layer; d) a first polymer thick film conductive strip applied to a portion of the substantially clear substantially conductive layer of the glass substrate; e) a plurality of second polymer thick film conductive strips, each of the plurality of second polymer thick film conductive strips applied to one of a plurality of portions of the polymer thick film dielectric layer; f) power connective means for connecting an electrical power source to the plurality of second polymer thick film conductive strips associated with the polymer thick film dielectric layer and to the first polymer thick film conductive strip associated with the substantially clear substantially conductive layer of the glass substrate; and g) a switching circuit connecting said electrical power source to said power connective means, said switching circuit sequentially energizing each of said plurality of second polymer thick film conductive strips; wherein when power is applied to the power connective means, portions of the polymer thick film phosphor ink layer illuminate and light substantially shows through the second surface of the glass, and wherein the power is applied to and removed from the power connective means selectively and in such a sequence that the portions of the polymer thick film phosphor ink layer are illuminated and darkened to provide animation as seen through the second surface of the glass substrate.
