The light-field 3D AR-HUD features a continuous depth range of 5-15 m and a 13° × 6° field of view, enabling precise fusion of virtual and real imagery. By integrating transparent projection and eye-tracking, it can dynamically adjust the display under complex lighting or shifting lines of sight, reducing fatigue while enhancing safety and immersion. This technology drives collaborative innovation across optics, panels, modules, and interactive systems, bridging domestic technology gaps and strengthening competitiveness in smart automotive and 3D display industries.
