EL, or Electroluminescent, is essentially a flat light bulb sandwich consisting of layers of conductive and non-conductive plastic and a layer of phosphor. The phosphor is laminated between two conductive layers and, as a voltage is applied between the two conductive layers, or electrodes, the phosphor emits light energy.

When a high-quality, high-resolution image is printed over the light, it behaves like a backlit sign.

By taking this idea further and dividing the printed image into several different sections that can be illuminated separately from one another, we can program and sequence these sections to provide an animated effect as we flash and/or fade the phosphor light in each of the sections in and out to create the impression of movement within a static printed image.

The illuminated phosphor does not generate heat the way conventional light sources do so EL runs cool. You can encapsulate or enclose the panels without fear of them overheating or melting.
