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.

Abstract: A gas sensing system includes a driving circuit chip, and a gas sensor, a temperature sensor, and a humidity sensor, which are located on the driving circuit chip. The gas sensing system compensates a gas sensing result based on at least one of a temperature sensing result and a humidity sensing result and generates a gas sensing signal. The gas sensor includes a first resonator and a first sensing film being configured to sense a first gas and located on the first resonator to be exposed to the outside. The temperature sensor includes a second resonator and an encapsulation layer located above the second resonator not to expose the second resonator to the outside, and the humidity sensor includes a third resonator.
