Fran has a lot of great content. Be sure to check out her videos on other rare displays like the IEE BINA-VIEW[1] or ONE-PLANE[2]. While looking for those videos I also found this one[3] where she browses through a catalog of display components from the early 1970s which features those and a lot of other display technologies that have mostly died off (since LED, LCD, and OLED are good enough for almost every use-case).
