Abstract: At least some example embodiments provide a fingerprint sensor, a fingerprint sensor package, and a fingerprint sensing system using light sources of a display panel. The fingerprint sensor includes an image sensor including a plurality of sensor pixels, the sensor pixels configured to sense light reflected by a fingerprint and generate image information corresponding to the fingerprint and a pinhole mask defining a plurality of pinholes, wherein each of the pinholes forms a focus for transmitting the light reflected by the fingerprint to the image sensor, wherein light is emitted from a plurality of organic light-emitting diodes (OLEDs) and is reflected by the fingerprint.
