US Patent 10528783 Display screen having fingerprint acquisition function

A display screen having a fingerprint acquisition function includes a display screen cover plate (1), several display image elements (2) arranged below the display screen cover plate (1) and several photosensitive image elements (3). The several photosensitive image elements (3) are arranged below the display screen cover plate (1) and evenly distributed in gaps between the several display image elements (2). The photosensitive image element (3) includes a photosensitive element (4) and a field diaphragm (5), and a diaphragm hole (51) of the field diaphragm (5) is located above the photosensitive element (4). The photosensitive element (4) receives light emitted by the display image elements (2), reflected by a position of a finger surface contacted with the display screen cover plate (1), and entered into the photosensitive element through the diaphragm hole (51) of the field diaphragm (5). The photosensitive image elements (3) are implanted among the display image elements (2) of the display screen, and the photosensitive image elements (3) acquire fingerprint images by using the display image elements (2) as light emitters, such that the display screen has a display function and a fingerprint recognition function. In this way, the integration, use convenience and user experience of the display is further improved.
