    摘要: The present disclosure relates to an anisotropic conductive film, a display device and a reworking method thereof. The anisotropic conductive film comprises: a first resin layer having positively photosensitive characteristics and conductive particles distributed in the first resin layer. Since the first resin layer has positively photosensitive characteristics, it can be decomposed after the exposure process. In this case, when failures occur in the binding of the display panel with the external circuit by the anisotropic conductive film, the first resin layer in the anisotropic conductive film can be decomposed by performing an exposure process on the anisotropic conductive film, so as to separate the external circuit from the display panel for reworking of the display panel. In this way, no heating process is needed, which not only simplifies the reworking procedure, but also is suitable for the reworking of a flexible display panel.

    摘要: The present disclosure provides a chip-on-film, a flexible display panel and a display device. The COF includes a plurality of output pads independent of each other. The plurality of output pads are disposed at a side of the substrate and are arranged in at least one row in the first direction. Virtual extension lines of all the output pads intersect at the same intersecting point on the base line. The flexible display panel includes a plurality of input pads independent of each other. The plurality of input pads are disposed in the binding region and are arranged in at least one row in the first direction. Virtual extension lines of all the input pads intersect at the same intersecting point on the base line.

    摘要: A method and a device for attaching a backing film to a flexible substrate and a roller for use therewith. The method includes placing the flexible substrate on a surface of a first worktable facing a second worktable and placing the backing film on a surface of the second worktable facing the first worktable; pressing the flexible substrate and the backing film by a rolling mechanism to attach them together. The rolling mechanism includes a roller having a surface encapsulated with segmented roller encapsulating rubber.
