Abstract: A sensing device includes a light-field image sensor and a sensing circuit. The light-field image sensor includes a plurality of subarrays. One of the subarrays corresponds to sensing pixels. The sensing pixels are to capture images of an object on or in proximity to a display panel by sensing lights from different directions. The sensing circuit is to generate a plurality of sub-images of the object according to sensing signals of the sensing pixels and shift each of the sub-images of the object by an off-set to generate an image data.

Abstract: An under display light field sensor is for sensing a fingerprint or touch on or in proximity to a display panel. The under display light field sensor includes a light-field image sensor and a plurality of micro-lenses on the subarrays of the sensing pixels. The light-field image sensor includes a plurality of subarrays of sensing pixels under the display panel. The sensing pixels in an identical one of the subarrays are configured to capture images of an object on or in proximity to the display panel by sensing lights from different directions. Each of the micro-lenses corresponds to one of the subarrays of the sensing pixels.
