Abstract
A matrix including a plurality of light emitting devices organized into a plurality of rows of first contacts and columns of second contacts. Row/column decoding switches each coupled to a number of individual rows/columns and to a number of row/column address lines for selecting an addressed one of the number of individual rows/columns, and to an individual row/column data lead for selecting a row/column decoding switch. The matrix and row and column switches are integrated onto a common substrate. A programmable voltage source is coupled to the column decoding switches by the column data leads and a programmable current sink is coupled to the row decoding switches by the row data leads.
