A display screen, comprising a panel (), a light-emitting plate (), a light blocking film () and an image sensor () that are stacked sequentially. The light blocking film () is provided with a light-transmitting imaging pinhole (); the light-emitting plate () is provided with a plurality of light-emitting units () and a circuit network () for driving each of the light-emitting units (), wherein the circuit network () divides the light-emitting plate () into a plurality of light-transmitting regions (), and a light path is formed by the panel (), the light-transmitting region () corresponding to a position of the imaging pinhole and the imaging pinhole (); alternatively, the light-emitting plate () is a plane light-emitting plate which is light-transmissive, and a light path is formed by the panel (), the plane light-emitting plate and the imaging pinhole (); and a part of light projected by the light-emitting plate () toward the panel () is reflected by a target object located on or outside the panel (), and then irradiated onto the image sensor () through the light path. According to the principle of pinhole imaging, the light passing through the imaging pinhole () can image on the image sensor (), thereby enabling the display screen to have both a display function and an image acquisition function.

Display screen

A display screen having a fingerprint acquisition function includes a display screen cover plate (), several display image elements () arranged below the display screen cover plate () and several photosensitive image elements (). The several photosensitive image elements () are arranged below the display screen cover plate () and evenly distributed in gaps between the several display image elements (). The photosensitive image element () includes a photosensitive element () and a field diaphragm (), and a diaphragm hole () of the field diaphragm () is located above the photosensitive element (). The photosensitive element () receives light emitted by the display image elements (), reflected by a position of a finger surface contacted with the display screen cover plate (), and entered into the photosensitive element through the diaphragm hole () of the field diaphragm (). The photosensitive image elements () are implanted among the display image elements () of the display screen, and the photosensitive image elements () acquire fingerprint images by using the display image elements () 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.

Display screen having fingerprint acquisition function

The present application discloses a method for controlling fingerprint acquisition based on a display screen and a related apparatus, which are applied to a display screen with a fingerprint acquisition function. In the disclosure, by detecting a fingerprint acquisition triggering instruction generated in an electronic device in real time, a preset fingerprint acquisition region of the display screen is controlled to emit light and a fingerprint sensor is triggered to acquire a fingerprint image, if and only if the fingerprint acquisition triggering instruction is detected. When the fingerprint acquisition triggering instruction does not exist, the display screen is not affected and the fingerprint sensor is in a non-operating state so as to save energy. Moreover, only the preset fingerprint acquisition region on the display screen is controlled to perform the fingerprint acquisition, and other regions on the display screen are not affected in fingerprint acquisition, therefore, the original display or the black screen state of the display screen is not affected, and it is ensured that the user can accurately touch the region with a finger to acquire a fingerprint image accurately and quickly. In this way, the cost of hardware integration may be reduced, the appearance may be simplified and the user experience may be improved.
