The capacitive touch panel (CTP) controller IC used in these displays is now manufactured on a new production line. The part number of the CTP controller IC has changed from FT5426-003 to FT5426G. The firmware ID number stored in CTP register 0xA6 has changed from 0x14 to 0x15. The FPC has also been redesigned as part of this change.
The changes described above should not have any impact on the part’s electrical or mechanical compatibility within your system. All 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.
The new touch panels will be labeled with a different revision control number on the FPC. See example below.
