A pilot plant facility has now been established to build DC electrolumescent panels. A new product is being made which combines analogue and digital readouts on one panel. Any panel up to 6″ × 18″ can be made due to the process simplicity which consists largely of screen printing techniques. The pilot product is 2″ × 7″ and displays are made six at a time. A combination of custom designed I.C.'s and microprocessor drive can be used to provide full, flexible solid state instrumentation.
