Abstract (en)
[origin: DE19631907A1] The invention concerns an LED-array mounted on a semiconductor substrate which is particularly suitable for using in printers and enables easy individual control of the LED's. To this end, the LED's are connected by an electrical layer which is situated on the semiconductor and divided into conductors in columns. Serial control occurs through an electroconductive layer (12, 13) which is situated in the semiconductor substrate and divided into individual conductors by trenches (10).
