The use of
integrated circuit technology to drive a display driver chip dates back to the late 1960s. 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 and Gerald P. Pighini 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. In the early 21st century, display driver chips are widely used for
mobile displays in
smartphones and other
smart devices as well as larger
flat-panel displays. Between 2003 and 2005,
LCD driver chips sold 9,821.2million units worldwide. ==See also==
