| Zusammenfassung: | A fingerprint identification apparatus including a transparent device, an image sensor disposed opposite the transparent device and a collimator disposed between the transparent device and the image sensor is provided. The collimator includes light shielding layers and transparent layers stacked sequentially. Each of the light shielding layers has openings respectively corresponding to pixel regions of the image sensor. Openings of the light shielding layers corresponding to a single pixel region are arranged in an oblique direction. The oblique direction and a normal direction of a pressed surface of the transparent device has an included angle [theta], and 0DEG < [theta] < 90DEG. |
