RCA's "TruFlat" TVs of the late '80s-'90s still used CRTs as well, but with flat (or nearly flat) screens. The tubes still operated as would any CRT, with high voltage in the kilovolt range, a yoke, flyback, etc. These were definitely not "flat screen" TVs as we know them today, as they were still designed for the NTSC television system (the DTV standard used today was still years away). I think the TruFlat TV's biggest selling point was, because of the design of the tube, there were no problems with reflections from room lighting or ambient light (such as bright sunlight), glare, etc. as was so common with standard CRTs having curved faceplates. RCA must have had a patent on this design, as I never saw this kind of "flat" CRT screen on any other make of television.
