METHOD FOR OPTICALLY DETECTING A FINGERPRINT OR AN OBJECT, AND DEVICE WITH AT LEAST ONE SCREEN

摘要

In a method for optically capturing a fingerprint or an object on a surface (2) of a cover plate (1) of a screen with a plurality of photosensors (4) which are each assigned to a respective display pixel (6), the display pixels (6) emit light radiation and the photosensors (4) capture light radiation from the display pixels (6) reflected by the surface (2) within a scan angle (8). The scan angle (8) describes in a virtual mirror image plane (9) the size of the display pixel (6).
