ABSTRACT:
This invention is a space-efficient pixel control circuit for a field emission flat panel matrix-addressable array display. The invention reduces by one the number of transistors required at the intersection of each row line and column line within the array. In addition, only two lines need be routed through the array (i.e., row and column). The array space saved by increased layout efficiency may be used to increase pixel density within the array. The new space-efficient pixel control circuit has a single transistor in a base electrode grounding path that is directly controlled by a row line. A current-limiting resistor is interposed between the single grounding transistor and a column line to which an inverse video signal is applied. The magnitude of the current through the current-limiting resistor is inversely proportional to the inverse column signal voltage. Thus, pixel brightness is directly proportional to the voltage drop across the current-limiting resistor.
