LED Displays in Distributed Information Systems

Light Emitting Diode (LED) display devices allow the display system designer maximum flexibility of display distribution within a display system. LED displays are available as discrete lamps, annunciators, and digits, as well as lamp and annunciator arrays and multidigit modules. Discrete display elements allow the display system designer to distribute displayed information exactly as he wishes without penalties of size or weight. Modular devices minimize assembly time of display systems by reducing the number of insertions required for groups of display elements. LED display elements of different colors allow easily designed multicolor display systems. Bicolor LED display elements, in addition to allowing the same freedom of distribution, provide the display system designer with greater information density than an equivalently sized single color display element. These capabilities are illustrated by use of display system design examples. Example designs emphasize the use of industry standard display devices as well as presenting examples of possible custom display devices for the automotive market.
