«Its chief, John Atalla — Greene's predecessor at Hewlett-Packard — sees early applications for LEDs in small displays, principally for indicator lights. Because of their compatibility with integrated circuits, these light emitters can be valuable in fault detection. “Reliability has already been demonstrated beyond any doubt,” Atalla continues. “No special power supplies are required. Design takes no time, you just put the diode in. So introduction becomes strictly an economic question." Bright Outlook for Optical Readers Atalla is particularly sanguine about applications of diodes in high-volume optical readers.»
