This type of ACF is in use in various applications. However, as LCD technology has advanced, ACF has been developed to respond to requirements such as improved contact resistance and pitch interval (corresponding to finer circuit patterns),
and reliability. In general, in order to attach the driver IC TCPs to the glass panel, for 10–12 in. SVGA/XGA, about 280–320 electrodes per TCP with 70–80 m pitch are required for a productive connection process. ACF provides the following suitable properties for LCD applications: (1)
