What’s in a name?
ELume translated from the French, meaning illumination. It also has another meaning, EL (LEF) short of Electroluminescence, a technology the founders of ELume were actively engaged in the 80’s early 90’s.
Chrysler dashboard (1967) Sigmatron Inc Santa Barbara California) where this LEF technology originated for space, subsequent digital display applications for early days desktop calculators. car dashboards etc, experienced financial difficulties which forced the company to close and sell the assets.
Walter E., who was their electronic circuits design consultant acquired the company . He raised millions in new capital and became the founder of Sigmatron Nova where he and his team adapted the EL technology to flat panel displays. Products were introduced to the market in the late 80’s.

Opportunity knocks – Sigmatron Nova
A team under the leadership of Mr. Walter E. whose dream and imagination grasped the potential for flat panel TV led to his pioneering efforts that brought to market a flat panel display technology called Thin Film Electroluminescence, sometimes referred to as a light-emitting film (LEF). In it’s simplest form a plain glass wafer with a transparent phosphor. Sandwiched between insulators and an transparent XY electrode matrix. Upon excitation with a small voltage, LEF’s emit a bright yellow light/picture.
LEF is/was direct sunlight readable and operational at temperatures from -200 degrees C to +200 C. These parameters are unique patented, and remain unchallenged. Although full color was shown to be feasible, it was the LCD displays that became a commercial success, LEF was relegated to niches as in military, industrial and medical markets.
