The viewingside coating is etched into character forming segments with leadsthat extend to the edge of the glass. Applying a voltage between the glass sheets alters the brightness of the liquid crystal. LSI: Large Scale Integration. 1) A technology that allows the inclusion of up to 100,000 simple logic gates on a single chip. 2) An integrated circuit that uses large scale integration.
