A viewing angle guide module is used for guiding light emitted from the integral imaging source. A light modulation module is arranged for modulating the light guided by the viewing angle guide module and reconstructing a 3D image. A rotation module is configured to enable synchronous rotation of the 2D image display module, the view angle guide module and the light modulation module, wherein. A rotation angle speed of the synchronous rotation is associated with the switching speed of the integral imaging source of the 2D image display module. For a 3D image reconstructed in a single visual area range, crosstalk created by the diffuse reflective feature of pixels on a 3D image in other visual areas can be eliminated, thereby improving the viewing experience.

The present disclosure is applicable to a display apparatus-related technical field, and relates to, for example, a rotating display apparatus using a light-emitting diode (LED) which is a semiconductor light-emitting device. The rotating display apparatus using a light-emitting device of the present disclosure may comprise: a fixed part including a motor; a rotary part positioned on the fixed part and coupled to a rotary shaft of the motor so as to rotate; a first light source module installed on the rotary part and including at least one first panel disposed on an outer peripheral surface of an imaginary cylinder in the same direction as the rotary shaft, and a first light-emitting device array in which individual pixels are disposed on respective first panels in the length direction of the first panel; and a second light source module installed on the rotary part and including at least one second panel disposed in a direction perpendicular to the rotary shaft, and a second light-emitting device array in which individual pixels are disposed on respective second panels.

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.
