What is Electroluminescence Technology or (EL)? How is it different than Illuminite?
EL technology uses a thin electrical panel requiring an internal power source to provide constant, sequential or pulsing sequences to a display. Illuminite is a retro-reflective glass beads technology that reflects light from an external light source.
Electroluminescent panels are paper thin panels that illuminate when an electrical current is applied to the panel. A print overlay (clear graphics layer) is laminated on top of the Phosphor layer, which is sandwiched between conductors. When an electrical current is applied to the relevant segment, the Phosphor crystals charge and emit light, which would then illuminate the printed overlay.
The Electroluminescent panel is connected to an inverter which would control which segments to illuminate and at different intervals, in order to create fantastic eye-catching animations even in bright ambient lighting conditions.
