ABSTRACT:
The electroluminescent panel is formed by depositing a first high dielectric strength adhesive layer on a transparent conductively coated plastic carrier strip, electrostatically depositing dry phosphor particles onto the first dielectric adhesive layer to form a phosphor particle approximate mono-layer (layer thickness not exceeding largest size particle electrostatically deposited) with particles disposed side-by-side uniformly across the dielectric adhesive layer, curing the dielectric adhesive layer with ultraviolet light through the carrier strip, depositing a second high dielectric constant filler layer on the phosphor particle layer to surround and overcoat the particles and then curing the second dielectric filler layer to embed the phosphor particles in a high dielectric constant matrix. The layers can be applied to and cured on the carrier strip as it continuously moves through a production line. Apparatus for practicing the invention is also disclosed.
