Core technology

The high integration of precision optics, Application-specific chips, and AI algorithms

Electronic grating technology

The cylindrical lens grating simulated by microelectronically controlled liquid crystals can turn the grating’s optical effect on or off. When displaying 2D images, the grating is turned off, making the LCD screen function like a regular 2D display with unaffected resolution. When displaying 3D images, the grating automatically turns on, presenting true 3D images with depth in both eyes, just like 3D movies.

Real-time eye tracking technology

Pixel light controlled by grating refraction is delivered to the left and right eyes, which are tracked in real time by cameras. The two eyes present two different images, and binocular parallax is the main physiological factor for forming 3D perception. 3D movies are also based on the principle of binocular parallax.

Naked-eye 3D holographic display technology

The naked-eye 3D holographic display made with 8K light field display technology creates an ultra-multitude of viewpoints in front of the screen. It allows multiple people to share the 3D screen, and each person can form binocular parallax and depth perception at different positions in front of the screen, just like the scene is truly placed in front of the eyes, without needing to wear any glasses.

Specialized Computing Chip

To meet the demand for ultra-fast response in 3D displays, the specialized computing chip developed based on FPGA achieves system minimization and performance maximization. It is applied in special fields such as 3D medical displays and 3D remote operations.

Precision Lenticular Grating

Backed by China’s precision manufacturing chain, lenticular gratings—core to holographic light field displays—have achieved precision breakthroughs amid advancing 4K/8K resolutions. Leveraging this, we’ve developed more complex, higher-efficiency grating solutions, supporting glasses-free 3D display advancement.

AI Acceleration Algorithm

In real-time 2D-to-3D image computation and spatial calculation for real-time 3D digital reconstruction (digital twin), AI computing models enhance operational efficiency, enabling truly “real-time” processing from data input to display output.
