Abstract

The invention provides a flexible printed circuit board and a display device. The flexible printed circuit board comprises a circuit wiring part, a golden finger end connected with the circuit wiringpart, and a detection bonding pad. The golden finger end comprises a substrate and a plurality of conductive contact pieces arranged on the substrate in an array mode. The substrate comprises a side punching edge; the detection bonding pad is positioned between the conductive contact piece and the side punching edge; a flexible printed circuit board is punched and molded; by observing and detecting whether the bonding pad is punched, whether the flexible printed circuit board has punching deviation can be judged, so that whether the flexible printed circuit board is qualified can be judged more quickly and accurately, the production efficiency of the flexible printed circuit board is improved, and the electrical connection performance of the flexible printed circuit board is guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible printed circuit board and a display device. Background technique [0002] With the increasing integration of electronic products, the utilization rate of flexible printed circuit boards (flexible printed circuit, FPC) has also been greatly improved. Flexible printed circuit board is a kind of highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has high wiring density, light weight, thin thickness, Good bendability. [0003] At present, in the manufacturing process of the flexible printed circuit board, the circuit test is performed on the flexible printed circuit board after the golden fingers are inserted, and then the die-cutting process is performed. The conductive contacts on both sides of the golden finger of the flexible printed circuit board and the side of the flexible printed circuit boar...
