Abstract
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).

21. A method for optically capturing a fingerprint or an object on a surface (2) of a cover plate (1) of a screen, comprising the following steps:
-
providing a plurality of photosensors (4); providing a plurality of display pixels (6); assigning each of said photosensors (4) to a respective display pixel (6), wherein 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), wherein the scan angle (8) describes in a virtual mirror image plane (9) the size of a selected one of the display pixels (6). - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
