    Abstract: Provided in the present application is a holographic display system, comprising an on-site holographic display system, a transmissive geometric holographic display system, a geometric holographic display system with folded optical path, and a reflective geometric holographic display system. A display element capable of directly displaying screens provided with depth of field information is used to project a diverging 3D image in the air without the aid of another reference light source. The image is converted by a projection screen of an equivalent negative refractive index flat lens to then obtain an observable 3D image suspended in the air, which reduces costs. At the same time, the 3D image may be displayed in front of or behind the projection screen, the display space is infinite, and in a very small device space, a super large screen and super deep depth of field may also be displayed.
