  • Patent number: 10572712
    Abstract: A fingerprint identification apparatus includes a cover lens, an optically clear adhesive layer, a fingerprint sensitive layer and a stress buffer. A total thickness of the cover lens and the optically clear adhesive layer is less or equal to a value “M”, wherein 0.3 mm?M?0.45 mm. The cover lens and the fingerprint sensitive layer are adhered by the optically clear adhesive layer. The fingerprint sensitive layer is disposed on the stress buffer. The stress buffer has greater hardness than that of the fingerprint sensitive layer.

  • Patent number: 10198131
    Abstract: A touch control device includes a cover lens, a groove, a fingerprint, and a touch sensing structure. The cover lens has a first surface and a second surface opposite to the first surface, in which the first surface is a touch surface. The groove is disposed on the second surface and has a top surface and a side surface adjacent to the top surface, in which an angle between the top surface and the side surface is greater than 90°. The fingerprint recognition structure is at least partially disposed on the top surface of the groove. The touch sensing structure is disposed on the second surface.

  • Patent number: 10001849
    Abstract: A touch panel comprises a substrate, a first mask structure and a dense structure. The first mask structure is disposed on a surface of the substrate and divides the substrate into a mask area and a visible area disposed adjacent to the mask area. The first mask structure is disposed in the mask area. The dense structure at least masks a surface of the first mask structure farther from the substrate.

  • Publication number: 20160077622
    Abstract: A touch device includes a cover plate, a substrate, a first adhesive layer and a strengthening glue. The cover plate and the substrate each has first and second opposite surfaces and a side surface between the first surface and the second surface. The first adhesive layer is located between the second surface of the cover plate and the first surface of the substrate. A space is formed between the side surface of the first adhesive layer, the second surface of the cover plate and the first surface the substrate a space. The space is filled with the strengthening glue. The cover plate and the substrate are fully bonded to enhance the strength, the compression resistance and the impact resistance of the touch device. Further the accuracy requirement for the first adhesive layer is lowered and the material of the first adhesive layer is saved.
