 In 1969, Hewlett-Packard introduced the HP Model 5082-7000 Numeric Indicator, an early LED display and the first LED device to use integrated circuit technology.Its development was led by Howard C. Borden, Gerald P. Pighini, and Egyptian engineer Mohamed M. Atalla, at HP Associates and HP Labs, who had engaged in research and development (R&D) on practical LEDs between 1962 and 1968.It was the first intelligent LED display, making it a revolution in digital display technology, replacing the Nixie tube and becoming the basis for later LED displays.
