Next-Generation Glasses-Free 3D Spatial Display Apparatus (patent)

Powered by Real-Time AI Depth Mapping & Dynamic LC Lens Tilting.

As spatial computing, immersive gaming, and automotive cockpit visualizations accelerate, the demand for glassesfree (autostereoscopic) 3D displays has surged exponentially. However, conventional autostereoscopic displays have historically failed to achieve mainstream commercialization due to three critical structural bottlenecks:

Tink Innovation has formulated a breakthrough system-level architecture that resolves these bottlenecks simultaneously. The proprietary patent establishes an end-to-end, sub-millisecond synchronized pipeline bridging highthroughput neural depth inference, active infrared (IR) pupil-corneal reflection tracking, and dynamic electric-field modulation of a liquid crystal (LC) lens layer.

💡 Key Architectural Pillars:

Real-Time 90fps+ 2D-to-3D Synthesis: Hardware-decoded 2D video is converted into pixel-level high-resolution depth maps via CNN/ViT architectures with guided upsampling and temporal bounding-box consistency filtering.

Sub-Pixel Active Eye-Tracking (PCCR + Kalman): Active IR LED illumination and 90Hz+ sensor arrays track pupil centers and corneal glints (PCCR), filtered by Kalman smoothing to eliminate micro-saccade jitter.

Dynamic LC Lens Optical Axis Tilting: Independent voltage modulation across segmented ITO electrodes dynamically shifts the physical refractive index profile, physically steering light rays toward moving eyes.

Active VAC Fatigue Mitigation: Built-in duration timers progressively compress the depth range over prolonged sessions to eradicate ocular fatigue.
