    Abstract: An image module includes a photosensitive element and a light-screening structure disposed on the photosensitive element. The light-screening structure includes a light-transmitting layer. The light-screening structure also includes a first light-shielding layer disposed in the light-transmitting layer and having a first light passage portion. The light-screening structure further includes a second light-shielding layer disposed between the first light-shielding layer and the photosensitive element and having a second light passage portion. The light-screening structure includes a condensing structure disposed on the light-transmitting layer. The first light passage portion and the second light passage portion correspond to the photosensitive element. Light passing through the condensing structure produces a concentrated beam, and the apertures of the first light passage portion and the second light passage portion are respectively adjusted according to the widths of the concentrated beam at the first light-shielding layer and at the second light-shielding layer.

    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.
