摘要： A driving chip and a display device, relating to the technical field of driving chip for displays, are disclosed. A surface of the driving chip has a first edge and a second edge opposite to each other. The driving chip includes connecting bumps and supporting bumps, which are arranged along the first edge to form at least one first bump column, and at either end of the first bump column, there is at least one of the supporting bumps; the connecting bumps and the supporting bumps are arranged along the second edge to form at least one second bump column, and at either end of the second bump column, there is at least one of the supporting bumps. A surface of the driving chip according to embodiments of the invention has bump columns, a supporting bump is disposed at an end of a bump column, and acts to support the driving chip favorably. Thus, upon bonding and packaging, the driving chip can bear a force in equilibrium as a whole, and occurrence of a problem of impression defectiveness is avoided.

摘要： A Chip on Film (COF) flexible circuit board and a display device using the COF flexible circuit board are provided. The circuit board includes: a substrate; a plurality of conductive terminals arranged separately in parallel over the substrate, each of the plurality of conductive terminals including a wide line and a narrow line; and a anisotropic conductive adhesive region provided over the substrate. A connection site of the wide line and the narrow line is located in an overlapping area of the anisotropic conductive adhesive region and the substrate. The embodiments of the invention can reduce the probability of the circuit board being broken and the undesirable phenomena such as open circuit.
