Holographic 3D display technology is a type of naked-eye 3D display technology that can achieve undifferentiated fusion of the virtual reconstructed image and real scene without causing visual fatigue in viewers.
LED lights are densely arranged on the rotor blades and rapidly spin to create a suspended 3D effect in mid-air using Persistence of Vision (POV) technology. It does not necessitate the use of glasses, is not limited by space or lighting, and provides flexibility, convenience, and energy efficiency.
Regular LED screens can only display 2D images and cannot present a realistic 3D effect. This leads to visual fatigue among the audience, consuming a significant amount of power.
To experience a 3D effect, one needs to wear headsets that are specifically designed for that purpose whict limits the usability of 3D displays for multiple people simultaneously.
3D displays are expensive and the depth of the 3D effect they produce may be limited. The displays are prone to damage and can be challenging to repair.
3D displays require dedicated projection space and are highly susceptible to lighting conditions. They can only be viewed in specific environments and are greatly limited by spatial constraints.
Ice screens and grid screens utilize a large spacing between LED pixels to achieve a transparent effect. However, this approach results in low image clarity and poor transparency.
