The capacitive touch controller used in these displays has been updated to a newer version of the IC. The part number of the CTP controller IC has changed from FT5426DQ8-003 to FT5426G. The firmware ID number stored in CTP register 0xA6 has changed from 0x03 to 0x05.
The changes described above should not have any impact on the part’s electrical or mechanical compatibility within your system. All of our testing has found the new version to be compatible with existing platforms driving the old display. We fully expect the new displays to fit and function without any issue for our customers.
