HN links it as a neat breakdown of an unusual CRT/LCD color technology.
A Technology Connections video on JVC's LCCS, a display hybrid that cycles a color LCD shutter over a monochrome CRT to produce field-sequential color without dots or stripes. It builds on his earlier videos about analog TV and compatible color.
“There's a neat breakdown of the tech on this YT channel” (HN, 2020)
Tangential but Alec Watson of Technology Connections looked at a studio monitor that worked on the principle of cycling an LCD overlay over a monochrome CRT. When I was growing up in Toronto, I want to say that I remember seeing these in use by “LiveEye” crews of CityTV whenever I went by an on-location shoot. (1) [this video]

The Sony Watchman[1] had the electron gun at the bottom shooting at a tilted screen instead of shooting at it from the back. This allowed to make a GameBoy-sized portable CRT TV. There is also an interesting LCD/CRT hybrid from JVC[2], it's not flat by itself, but the way it adds color to an otherwise black&white screen could be used in slim designs.

Modern video projectors also display color channels sequentially and also exhibit that effect. Also, this particular CRT technology was not only used in oscilloscopes: [this video]
