• made in 1989, I can't find any teardown that shows any precise information, like...
  

  • mechanical dimensions
  • what interface it uses at the signal level

  it's only known that it's a grayscale CGA LCD

• I used to own one. I think I still have the technical reference manual somewhere in the bunker.
  IIRC it was a twisted nematic hitachi chipset.

  Display: LCD super-twisted nematic, green Chip Set MN5504 LCD CGA emulation       from vintage computer
  
  The 1100 FD has an 80 x 25, high-contrast liquid crystal display
  with 640 x 200 resolution.  The fold-over display measures
  approximately nine inches diagonally and closely resembles the
  aspect ratio of conventional video monitors.

  found some info here.
  if you find the time, can you open, and measure the STN LCD-panel size?
