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.
