    Abstract: A sensor includes a first electrode and a second electrode, and a photo-active layer between the first electrode and the second electrode. The photo-active layer includes a light absorbing semiconductor configured to form a Schottky junction with the first electrode. The photo-active layer has a charge carrier trapping site configured to capture photo-generated charge carriers generated based on the light absorbing semiconductor absorbing incident light that enters at least the photo-active layer at a position adjacent to the first electrode. The sensor is configured to have an external quantum efficiency (EQE) that is adjusted based on a voltage bias being applied between the first electrode and the second electrode.

    Abstract: A fingerprint sensor may include first and second electrodes, a light absorption layer isolated from direct contact with the first and second electrodes, and an insulation layer between the first electrode and the light absorption layer and further between the second electrode and the light absorption layer. A reflective layer may be between the light absorption layer and the first electrode. The insulation layer may include a first insulation layer between the first electrode and the light absorption layer, and a second insulation layer between the second electrode and the light absorption layer. A fingerprint sensor array including a plurality of fingerprint sensors may at least partially expose a plurality of sub-pixels of a display panel on which the fingerprint sensor array is located.

    Abstract: An OLED display panel may include a substrate, an OLED light emitter on the substrate and configured to emit light, and a visible light sensor on the substrate and configured to detect at least a portion of the emitted light based on reflection of the portion of the emitted light from a recognition target. The visible light sensor is in a non-light emitting region adjacent to the OLED light emitter so as to be horizontally aligned with the OLED light emitter in a horizontal direction extending parallel to an upper surface of the substrate, or between the substrate and a non-light emitting region adjacent to the OLED light emitter such that the visible light sensor is vertically aligned with the non-light emitting region in a vertical direction extending perpendicular to the upper surface of the substrate.
