1. An under-display camera assembly, characterized by comprising:
an organic light-emitting diode display screen, a display area of which includes an under-display camera area and a non-under-display camera area, wherein a pixel density of the under-display camera area is set to be smaller than a pixel density of the non-under-display camera area; and
a camera module, an optical axis of which is perpendicular to a surface of the organic light-emitting diode display screen, and the camera module being located at a rear end of the under-display camera area, and the camera module including an iris diaphragm, a lens group and a photosensitive assembly,
wherein the organic light-emitting diode display screen includes a pixel light-emitting layer, and the iris diaphragm is provided between a bottom surface of the pixel light-emitting layer and a top surface of a foremost lens of the lens group, and the iris diaphragm has a closed state and a transmission state, and the iris is controllably switched between the closed state and a transmission state, and the closed state is a state in which the iris diaphragm closes an optical path of the camera module, and in the closed state, the iris diaphragm reflects light from the organic light-emitting diode display screen or the iris diaphragm itself emits light and the emitted light is emitted from the front of the organic light-emitting diode display screen, and the transmission state is a state in which the iris diaphragm opens the light path of the camera module.
