       How come liquid crystal displays, especially for things like computer terminals, didn't dominate the market? Cathode ray tubes are such an awkward technology, requiring high voltages, fragile parts and a lot of space. Liquid crystal displays and neon lamp displays already existed at the time, but everyone went for the CRT's, until laptops set new requirements. Anybody knows why?

       @deshipu In the late nineties, my Amiga was pushing a 19” CRT at 1600x1200. LCDs that humans could afford had much lower resolution until a lot later.

       @tek Yes, but that is mostly because the CRTs had already 50 years of intense development and widespread use, while LCDs were super niche. But both technologies were there at the beginning, and if the world went with LCDs, it would be CRTs that were underdeveloped at the time.

       @deshipu I’m not so sure of that. There are some pretty tricky material science problems in making a good one, where it’s a lot easier to incrementally improve a CRT.

       @tek People have literally made LCD and OLED displays at home, in their garages. Haven't heard about anything like that with CRTs.

       @deshipu In the 80s, though?

       @tek The tools were there, all that was missing was people trying all kinds of things and seeing which one works better, and for that you just need there to be a need. Developing a good quality fast luminofor didn't happen overnight either.

       @deshipu iirc: cost, dynamic range, color distortion at non-straight-on viewing angles

       @deshipu ooh another one -- ghosting on updates was *awful* in the early years. even on a text terminal that kinda sucked(we had a 286 laptop with a b&w lcd screen back in the day -- even without the color issues a crt was considered a better experience for working on. :D)

       @brion IIRC early CRTs had horrible ghosting as well, and flickering on top of that...

       @deshipu @brion I don't think LCDs got nice until the early 90's, even in the small size in laptops and then only b&w maybe grey scale. (I'm thinking of the Apple Powerbooks as the first nice ones?)
