Tunable Color Electroluminescence Display Operated by Pulse Code Modulation
As a new driving system of the tunable color electroluminescence (TCEL) devices, a series of technical trials on the pulse code modulation has been investigated. It has been shown from the results that the control of number of pulse ratio driving system with a constant pulse height and a constant pulse width is the best system for the continuous color mixing and variations with constant luminance. A series of technical data on the dual coloring TCEL devices are presented and discussed. This TCEL devices open a wide varieties of applications in the field of information display systems.
