In this study, APL has been introduced into the ACFs system. Then, the effects of APL ACFs properties on the conductive particle movement and interconnection stability of ultra-fine pitch COG applications were investigated. The APL structure can not only significantly suppress the conductive particles movement for ultra-fine pitch COG applications but also prevent electrical short circuit formation between electrodes. After ACFs bonding process, the percentage of captured conductive particles of the conventional ACFs was 33%, however, that of PAN APL ACFs showed 95%. In addition, the APL ACFs showed excellent electrical properties such as stable contact resistance without any open or short circuits.
