Abstract
An electro-optic integrated circuit including an addressable array of light emitting devices, a column decoder and a plurality of address lines formed on the substrate. There are n=2{integer[log(m)/log(2)]+1}, where m equals the number of columns, address lines each including an external connection pad. The decoder includes a switching circuit connected to each column for activating the column and a plurality of sets of diodes connected to the address lines and the switching circuits so that each set of diodes has a unique code produced by a combination of diodes in that set and the address lines to which the diodes in that set are connected.
