LED display
Nick Holonyak
The LED display is not Holonyak’s invention — it is HP’s. Holonyak’s 1962 GaAsP LED enabled it. HP’s 1969 Model 5082-7000 was the first intelligent, IC-integrated numeric display — fast, solid-state, low-power, and monochromatic. It displaced Nixie tubes but could not render text, graphics, or colour. Later all-LED flat panels remained monochrome and experimental.
