I'm looking at replacing the SCREEN on a laptop. The p/n is LTN156AT27 - H01.  While searching for a replacement, I see other part numbers that end in H02 and H04.  Anyone know what these H0 numbers mean?There are experts here READY to HELP you. . But his is not a char room. You need to give as much detail as needed. Make, model, part number of both the laptop and the part.  Replacement parts are NOT standardized in the laptop industry. Each maker has their own part list.
I did receive a reply from a vendor on this just now. Here's what they said:

In this CASE, there's no significant difference between any of them that we know of. The H01, H02, etc. are revision numbers, so an H04 screen may have slightly updated firmware over an H02, or a minor component change, but the compatibility and function of the screens is the same. It is good to keep an eye on revisions though, as some screens may have more significant differences (for example,
LTN173KT01 H01 usually has the CONNECTOR on the opposite side of
LTN173KT01 K01).
