Display Device, Electronic Apparatus, and Image Acquisition Method

An electronic apparatus, comprising:

• a casing;
• and
• a display device, the display device is mounted on the casing;
• wherein the display device comprises a display face and a bottom face facing away from each other, and wherein between the display face and the bottom face, the display device further comprises:
• a photosensitive layer comprising a plurality of photosensitive units, the plurality of photosensitive units being disposed on a substrate;
• and
• a plurality of collimators disposed between the photosensitive layer and the display face, the collimators defining light-passing holes aligned with the photosensitive units, wherein the light-passing holes are capable of allowing light signals to pass through to reach the photosensitive units.

An image acquisition method for a display device, the display device comprising a display face and a bottom face facing away from each other, wherein between the display face and the bottom face, the display device further comprises a photosensitive layer disposed on a substrate, and a collimator defining light-passing holes;

• and wherein the image acquisition method comprises:
• receiving imaging light signals comprising a target light signal, wherein the target light signal sequentially passes through the display face, the light-passing holes, and reaches the photosensitive layer;
• and
• acquiring an image according to the imaging light signals;
• wherein the imaging light signals refer to all the light signals received by the photosensitive layer, and the target light signal refers to a light signal that, after passing through the light-passing hole, reaches the photosensitive layer.
