Who came out with the first flat face CRT? I'm not talking about the Trinitron, which as we all know is flat from top to bottom technically.
I seem to recall an 80s Zenith with a flat CRT, way before they became a norm in the end-of-CRT era.
It had to be an all-solid state TV/monitor I assume. Were any monochrome CRTs with a flat face produced?
