The quality and reliability of the LCD module depend on the way in which the driver integrated circuit (IC) is attached to the panel As a high-density interconnector material, anisotropic conductive adhesive film (ACAF or ACF) is the most popular material for attaching the tape-carrier packages (TCPs) and the tape automated
bonding (TAB) and chip-on-glass (COG) packages of the driver IC to the LCD panel.
