Since I have uptreamed 4 devicetrees containing that touchscreen (and
marked that as todo). I tried to look it up:
https://fccid.io/NOIKBN249/Internal-Photos/Internal-Photos-3802584.pdf
Page 4 might be interesting. Something below that 3d code (zbarimg does
not recognize it) Peeling up the label reveals:
TT21000
-44LQI
1802 TWN
6491U0 (two illegible characters)
You find it in the net:
