A fluorescent layer of contact luminescent elements for recognizing fingerprint and method of manufacturing thereof and fingerprint input device using thereof

摘要

The present invention improves the phenomenon in which the fingerprint image is blurred by allowing the fluorescent signal generated at the surface of the device to be transmitted only in the vertical direction with respect to the surface of the device by using the microchannel filled with the phosphor, and the formed fingerprint image is controlled at the micro level. By doing so, it is effective to obtain a correct fingerprint pattern. To this end, in particular, the thin film 110 composed of a polymer or ceramic; A plurality of micro channels 120 penetrating the thin film 110 at regular intervals; A fluorescent layer of a touch light emitting device for fingerprint recognition, a method of manufacturing the same, and a fingerprint input device using the same are disclosed.
