The blue led was released in 1993. I remember reading an article in Wired magazine (back when magazines were published on paper) about the invention. Gladly, the article is still available online: https://www.wired.com/1995/03/blue-laser/
I talked with some friends about the “true boo-roo” led, and the phrase stuck with us (that’s why I still remember the article). At the time (almost 30 years ago) we had no idea how important the invention was, even when we realized that it allowed for rgb led light.
But we had no idea leds would be miniaturized to be used in screens and be as ubiquitous as they are today. Living through all this technology evolution has been quite the ride.
I remember reading about this stuff since the eighties and people had a pretty clear idea of the implications.
Well now the digital screen is everywhere, it bends, and some people strap it to their eyes. It's crazy how far it's come
That was a great read, thanks. It made me realise I don’t even remember the last time I changed a light bulb!
I've changed my fair share of LED bulbs. Nowhere near the frequency of incandescent though.
