AN INVESTIGATION OF SOLID STATE DISPLAY CONTROL CIRCUITRY.

Abstract

Electroluminescent phosphors and lamps have advanced during recent months to the point that usable electroluminescent displays are now practical. However, there exists a considerable gap in between the technology of displays and that of the necessary solid state control circuitry. This work is an attempt to develop such control circuitry. The various advantages and disadvantages of ferroelectric elements, photoconductors, and silicon controlled rectifiers are analyzed. Silicon controlled rectifiers are selected as primary control elements, and control circuits are developed for bar graph and pointer displays. The pointer display uses SCR controlled variable voltage dividers and provides for the control of several lamp segments by a single control element. (Author)
