Abstract

For more than ten years ago, electroluminescent display devices have been used primarily for lighting purposes, and have been largely confined to glass constrution. The simplest variable dis play device is a seven- or nine-segment numeric readout, by increasing the number of segments and changing rectangular to circular segments, more number and letter displays have been obtained. The familiar 35-dots-per-letter in 5x7 array is the best-known example
