[0002] Display screens are the main components of electronic devices such as mobile phones, tablets, televisions, and computers. The display content is mainly controlled by the electrical signals input by the integrated circuit (IC) carried by the chip-on-film (COF), and the electrical signals on the IC carried by the COF come from the flexible printed circuit (FPC). Moreover, in the actual preparation process, the IC carried by the COF needs to form an electrical connection with the display screen and the FPC, which requires the use of ACF materials through a binding process.
