1961 hand held color tv?

[Jeffhs]

RCA had what it referred to as "TruFlat" color TVs in the late 1980s or early nineties. The screens of these sets may have been flat, but the sets were still NTSC analog. I wonder whether these TruFlat sets had special or custom-made CRTs (which I seriously doubt), or if the flat screen was part of a projection system in which the image from a small color tube was projected onto the screen to create the illusion of a flat picture.
