<p>A matrix (11) 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 (15, 12) each coupled to a number of individual rows/columns and to a number of row/column address lines B0 - B1, A0 - A1) for selecting an addressed one of the number of individual rows/columns, and to an individual row/column data lead (R0 - R35, C0 - C59) for selecting a row/column decoding switch (15, 12). The matrix (11) and row and column switches (15, 12) are integrated onto a common substrate. A programmable voltage source (54) is coupled to the column decoding switches (12) by the column data leads (C0 - C59) and a programmable current sink (64) is coupled to the row decoding switches (15) by the row data leads (R0 - R35).</p> |
