    Abstract: A chip on film package includes a base film, a chip and a heat-dissipation structure. The base film includes a first surface and a second surface opposite to the first surface. The chip is disposed on the first surface and has a chip length along a first axis of the chip and a chip width along a second axis of the chip perpendicular to the first axis. The heat-dissipation structure includes a covering portion. The covering portion at least partially covers the chip, exposes a side surface of the chip, and has a first length along the first axis and a second length along the second axis being longer than the chip width of the chip. The side surface connects a top surface and a bottom surface of the chip. A heat-dissipation structure is also provided.

    Abstract: A chip on film package includes a base film, a chip and a heat-dissipation sheet. The base film includes a first surface. The chip is disposed on the first surface and having a chip length along a first axis of the chip. The heat-dissipation sheet includes a covering portion and a first extending portion connected to the covering portion and attached to first surface. The covering portion at least partially covers the chip and having a first length along the first axis. The first extending portion has a second length along the first axis substantially longer than the first length of the covering portion, and the covering portion exposes a side surface of the chip, wherein the side surface connects a top surface and a bottom surface of the chip.

    Abstract: A chip on film package includes a base film, a patterned circuit layer, a chip and a reinforcing sheet. The base film includes a first surface, a second surface opposite to the first surface and a mounting region located on the first surface. The patterned circuit layer is disposed on the first surface. The chip is mounted on the mounting region and electrically connected to the patterned circuit layer. The reinforcing sheet is disposed on the first surface and/or the second surface and exposes the chip, wherein a flexibility of the reinforcing sheet is substantially equal to or greater than a flexibility of the base film.
