Method for checking tape automated bonding region of display module

A method used in fabricating processes of a first display module and a second display module for checking a first and a second positions of tape automated bonding (TAB) regions on said first and second display modules, comprising steps of:

• providing a main holder having a holding panel;
• providing at least a first test plate and a second test plate, wherein said first test plate, said second test plate and said holding panel have the same peripheral sizes, said first and second test plates respectively have a first hollow portion and a second hollow portion for suiting said first display module and said second display module, and a first circuit plate and a second circuit plate are respectively disposed around said first and second hollow portions;
• placing said first display module on said first test plate, and placing said first display module together with said first test plate on said holding panel of said main holder for checking whether said first position of said tape automated bonding region of said first display module fits a third position of said first circuit plate in said fabricating process of said first display module;
• and
• placing said second display module on said second test plate, and placing said second display module together with said second test plate on said holding panel of said main holder for checking whether said second position of said tape automated bonding region of said second display module fits a fourth position of said second circuit plate in said fabricating process of said second display module.
