Blue LEDs are the bane of my light-sensitive eyes' existence, and it pains me so to know they almost never existed at all. I keep a PC repair kit with me, even though I dont have a desktop computer, because I need to take all of my electronics apart and take these stupid blue LEDs out of them.

LED lighting wouldn't exist if not for blue LEDs. And neither would much of modern display technology. The importance of this discovery was not because we could make shiny blue light with it.

LED lighting in practice is typically terrible (though not always or inevitably): the spectrum is too blue and too spiky, without due respect for human needs. It has ruined nighttime lighting, especially outdoors in applications like street lamps, car headlamps, camp lamps, and flashlights. Whatever marketing people are making decisions in the lighting industry have insufficient understanding of human color vision and/or just don't care, consumers or other people making purchasing decisions have poor understanding of the options and their effects, and government regulation has not kept up with the technology.

> And neither would much of modern display technology.

The vast majority of monitors and televisions are still LCD, and they would work Just Fine if they were still using fluorescent backlights.

It would have more of an impact on phones, but not earth-shaking.

Do blue OLEDs even use the same technology?
