Working at General Electric’s New York R&D lab, scientist Nick Holonyak fires up the first working visible-spectrum light-emitting diode, producing a single small red light. (Texas Instruments had already created infrared LEDs the year before.) Too expensive to mass-produce initially, LEDs will become commonplace in calculators and other electronic devices in the 1970s, though more modern variants in the 1990s will lead to a revolution in lighting and display technology, resulting in flat-screen computer monitors and televisions and spinoff technology such as tablet computers and portable telephones with LED-based touchscreens – all unimaginable in 1962.
