Back in the 80's there was talk of using frame stores to store the image and play it twice, to get the refresh rate to 100Hz. This was when CRTs were the only game in town.

I first saw this in a lab in the mid 1980s, before commercially available 100Hz sets. At first I could hardly see flicker even at 50Hz but after a while I became attuned to it. Watching 100Hz pictures felt very relaxed compared to 50Hz.

LCD sets inherently don't flicker, regardless of frame rate. The LCD cells have a zero order hold function by their nature. Motion portrayal is a different problem. LCDs have a laggy response, almost inevitably worse than CRTs, despite the whole arsenal of tricks employed by panel and set makers.
