LG monitors naming system ?

  • what do those letters and numbers stand for ?
    for example:
    W2253TQ-PF
    W - wide
    22 - size
    53 - ?
    TQ - ??
    -PF - ???
    im getting that all of this is similar to Mobo Naming from MSI, DFI, or GigaByte (all of the letters and numbers have a purpouse), so if anyone knows, please give me an explanation, or a link to where i can read this.
    and, when you explain, give me, please, an example, for these two monitors:
    W2284F-PF
    M197WD-PZ DVB
    thanks in advance!
