Display screen

Abstract

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.
