A chip on film (COF) package includes a base film having an upper surface and a lower surface opposite to each other, a bridge film having an edge that overlaps the base film, and an upper surface and a lower surface opposite to each other, a display driver integrated circuit (IC) mounted on the upper surface of the base film, and a heat dissipation member arranged in correspondence with the display driver IC on the lower surface of the base film. The upper surface of the base film and the lower surface of the bridge film adhere to each other in their respective long axis directions, and a long axis length of the bridge film is greater than a long axis length of the base film.

Chip-on-film package and display apparatus including the same

A chip on film package is provided. The chip on film package includes a film substrate with a base film, a conductive pad extending in a first direction on the base film, and a conductive line pattern extending from the conductive pad; a semiconductor chip provided on the film substrate; and a bump structure provided between the semiconductor chip and the conductive pad. A first peripheral wall and a second peripheral wall of the bump structure extend in the first direction and define a trench, a portion of the conductive pad is provided in the trench, and the conductive pad is spaced apart from at least one of the first peripheral wall and the second peripheral wall.

Chip on film package with trench to reduce slippage and display device including the same

A chip-on-film package includes a base film including an upper surface and a lower surface that opposite from each other, a semiconductor chip mounted on the upper surface of the base film, a heat emission layer disposed on the lower surface of the base film to at least partially overlap the semiconductor chip in a thickness direction, an insulating layer disposed on a lower surface of the heat emission layer, and a protective layer surrounding side and lower surfaces of the insulating layer. Accordingly, thermal fatigue of the chip-on-film package may be reduced, and reliability may be increased.
