Abstract
An apparatus for providing lighted areas on a surface. The apparatus comprises a glass substrate having at least a first surface that includes a substantially clear substantially conductive layer, and a second surface that does not include a substantially clear substantially conductive layer. The present apparatus also includes a polymer thick film phosphor ink layer applied to the first surface of the glass substrate, a polymer thick film dielectric layer applied to at least a portion of the phosphor ink layer, and a polymer thick film conductive layer applied to at least a portion of the dielectric layer. Further, the apparatus includes power connectors for connecting electrical power to the polymer thick film conductive layer and to the substantially clear substantially conductive layer of the glass substrate. When power is applied to the power connectors, the polymer thick film phosphor ink layer illuminates and light substantially shows through the second surface of the glass substrate. There is also an apparatus for providing animated lighted areas on a surface.
