Tektronixs an American manufactur of oscilloscopes,
made a full color LCCS  LCD  cathode-ray tube or CRT Hybrid display, that ended up with the japanese JVC? or Japan Victor Company.
see this part of the video at- 9:18

I have a scope with the NuColor display, it's fantastic. It produces a beautiful image, sharp with that smooth clean CRT look but in full color without the screendoor effect of a shadow mask. It looks much better than the TFT displays they used on later scopes.

Maybe the patent has expired and Tek didn't feel the need to extend it. They were using the colour LCD shutter, monochrome CRT on the TDS754 back in the mid '90s. It did have a bit too much peripheral vision flicker if you moved your eyes too quickly.

I agree. I can't work with those displays at all. I upgraded every Tek scope from that series I owned with a TFT display.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

That is a flaw it shares with DLP, I've noticed it appears much worse to me when I'm very tired, most of the time I don't really see it at all. I think the end result is still very good though, it looks much better to me than LCDs of the era, it's so smooth and the contrast ratio is phenomenal. Nice colors on an inky black background, only OLED comes close.

Yes, very similar, though colour wheels typically alternate much faster than those LCD shutters could manage.

Oh yes, no question.
