Tektronix did it with a totally wild set of LCD color filter shutters over the whole face of the CRT, and then sequential color fields. It meant you got the whole spatial resolution of the display, but one third the temporal resolution. Similar to color-wheels in DLP projectors, really.
The system was called NuColor, if you want more detail.
The Bayer filter method in TFA is sensitive to perfect alignment between the filter and the image, which proved impractical in the real world. Sure makes for a neat experiment, though.

- jeffbee 6y agoMan, that was the golden age of analog video right there. In the 90s it became just barely possible to do a lot of processing of analog video using a shitload of expensive electronics, and people did. Those were the days of "line doubling" deinterlacers that were as big as shoeboxes and as expensive as cars.
