Back-to-back diode current regulator for field emission display

摘要

A circuit for regulating the pixel current in a field emission display so as to enhance pixel-to-pixel uniformity of pixel current. The pixel current flows through a pair of diodes connected back-to-back. A transistor circuit controls the voltage across the back-to-back diode pair, so that the voltage/current transfer characteristic of the diode pair determines the pixel current.
