Actually, LCDs are pretty easy to deploy .. they take a lot less support circuitry. Your LED digits are the guys that will need your 4 score and 7 tiny wires. > A back-lit LCD would have virtually no segment drive current > but would need a supply for whatever light source was used.

On the other hand, large, LED backlit LCD's can draw astonishing amounts of current for their backlights. Electroluminescent backlights draw a lot less current, but need weird voltages. .. _______________________________________________ http://www.piclist.com View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
