In that era you had CRTs or Rear Projection TVs.

Rear Projection was bigger (55" 4:3) but often times was susceptible to burn-in and had a worse quality picture compared to a CRT

Before LCDs it was plasma which until the the late 2000s had more technical advantages over LCD Refresh rate, contrast. LCDs couldn't really match them until the 2010s (I never had a plasma display though so I don't fully understand plasma)

DLP was a thing and could get up to and over 80" while maintaining quality but DLP could not be wall mounted as they were quite big like rear projection screens
