Fingerprint recognition device
Abstract:
A fingerprint recognition device includes a light source, a light conversion layer, a light detector, and a light filter. The light source is configured to emit a first light having a first wavelength. The light conversion layer is configured to convert the first light to a second light having a second wavelength different from the first wavelength. The light detector is configured to detect the second light reflected by a fingerprint. The light filter is disposed between the light conversion layer and the light detector, and configured to substantially filter out the first light and substantially pass the second light.
