| 20120014569 | METHOD AND APPARATUS FOR SLIM TYPE FINGERPRINT RECOGNITION DEVICE - A mobile slim type fingerprint recognition device has a hand held housing and a light emitting sensor operatively connected to the housing. The light emitting sensor has a transparent insulating layer. A transparent electrode layer overlays the transparent insulating layer. A luminescence layer overlays the transparent electrode layer and a stray light shield layer overlays the luminescence layer. The luminescence layer and the electrode layer are configured such that an electric field can be generated between an object to be imaged and the transparent electrode layer. | 01-19-2012 |
