摘要： The invention discloses a COF packaging unit and a COF packaging tape. The COF packaging unit comprises COF baseband(s), IC Die(s) packaged on the COF baseband(s), and input end wires and output end wires connected with the IC Die(s); the input end wires and the output end wires are respectively provided with input terminals and output terminals at two edges of the COF baseband. In the invention, because the input terminals and the output terminals are pitched along the edges of the COF baseband, the length of the single COF packaging unit is set in accordance with the pitching requirement of the input end wires and the output end wires, so that the COF baseband can have sufficient area for wiring, to adapt to the requirement of large LCD panels. Thus, resources are reasonably integrated and used, equipment utilization rate is increased, material purchasing cost is saved, and economic benefits are increased.

摘要： A chip on film (COF) is disclosed in the present disclosure, which comprises an adhesive base layer, a driving integrated circuit (IC), an adhesive layer and a copper layer. The driving IC is embedded on a surface of the adhesive base layer; the adhesive layer is located under the adhesive base layer; the copper layer is located under the adhesive layer. The adhesive base layer is formed with a heat and pressure spreading structure. A heat and pressure spreading structure is disposed on the adhesive base layer of the COF so that deformation or unevenness of the glass substrate in the bonded area can be avoided when the COF is thermally pressed to the glass substrate of the LCD. These guarantees the consistency between the bonded area and the unbounded area, the bonded area and the unbounded area of the glass substrate will have the same transmissivity and luminance.
