The codes are readable once you know the pattern. T for our panel line, then L for FHD or U for UHD, then the diagonal in inches, then SL, then T if it is a touch panel, then a dash and a brightness letter.
TU750SL-HC01 is therefore the 75 ″ UHD at 3000 nit. TL320SLT-HB01 is the 32 ″ FHD touch at 2000 nit. Once you can read the code you can read a quotation.
