The invention provides a
chip-on-film binding structure, a display module and a terminal device. The
chip-on-film binding structure comprises a
chip-on-film which comprises a first pin; and a flexiblecircuit board which comprises a second pin, wherein the second pin is connected with the first pin, the first pin comprises a first end and a second end which are opposite to each other, the second pin comprises a third end and a fourth end which are opposite to each other, and the first end of the first pin and the third end of the second pin are overlapped to form an effective contact area; thesecond end of the first pin and the fourth end of the second pin extend out of the two opposite sides of the effective contact area respectively, a first
exposure area is formed at the second end ofthe first pin, and a second
exposure area is formed at the fourth end of the second pin. According to the chip-on-film binding structure, the display module and the terminal device, the problem that the exposed part of the FPC pin is easy to corrode is effectively improved while the FPC and COF
binding process requirements are met, the poor display of a display screen is reduced, the reliability is improved, and the service life of a product is prolonged.
