Electronic device and imaging method thereof

An electronic device, comprising:

• a pixel layer including a plurality of pixel units, the plurality of pixel units being configured to display an image;
• an image display control apparatus electrically connected to the pixel layer and configured to control the plurality of pixel units in the pixel layer to sequentially display at least one corresponding first image according to at least one first image signal;
• a photosensitive layer located on a side of the pixel layer facing away from a light-exit side of the pixel layer, the photosensitive layer being configured to receive a reflected light formed after an emergent light emitted from the pixel layer when displaying one first image at each time is reflected by an object to be photographed, and to convert the reflected light received at each time into a second image signal;
• and
• a processor electrically connected to the photosensitive layer and configured to determine an image of the object to be photographed according to the at least one first image signal and second image signals corresponding to the at least one first image signal;
• the electronic device further comprising a base;
• wherein each pixel unit includes a pixel circuit and a light-emitting unit that are stacked on the base, and the pixel circuit is configured to drive the light-emitting unit to emit light;
• wherein the light-emitting unit is closer to the photosensitive layer relative to the pixel circuit;
• the light-emitting unit includes a first electrode layer, a light-emitting functional layer and a second electrode layer that are sequentially arranged in a direction towards the photosensitive layer, the second electrode layer is capable of reflecting light, and the second electrode layer is provided with first light-transmitting portions configured to transmit the reflected light received at each time;
• the base is provided with second light-transmitting portions configured to transmit the reflected light received at each time and the emergent light, and the second light-transmitting portions are light-transmitting holes distributed in an array.
