Core Technologies
Six foundational technologies driving autostereoscopic display innovation
Holographic Light Field Display
Advanced light field rendering that reproduces real-world light distribution in 3D space, delivering natural depth perception and volumetric realism.
Real-Time Eye Tracking
Tracks the user's eye position in real time, dynamically adjusting the 3D image projection angle for an optimal viewing experience from any position.
Switchable Electronic Grating
Advanced liquid crystal grating technology enables instant switching between 2D and 3D modes. In 2D mode, the grating is disabled — delivering full native resolution with zero pixel loss.
Real-Time 2D-to-3D Conversion
A powerful real-time conversion engine that transforms ordinary 2D content into 3D format with low latency and high quality.
Unity3D Real-Time Rendering
Complete Unity3D SDK support enables developers to rapidly create and render 3D content, including real-time 3D reconstruction.
Precision Lenticular Lens Array
High-precision cylindrical lens arrays deliver exceptional glasses-free 3D display quality across a wide range of display sizes.
Fundamentals of 3D Display
"Binocular parallax" is the single most important factor in stereoscopic depth perception. Glasses-free 3D displays deliver genuine depth directly viewable on screen — no glasses, no headset, no special equipment required.
🧬 Physiological Factors (True 3D)
When the human brain processes binocular cues from a flat display, the resulting depth perception is immersive and compelling — this is "true 3D."
🎨 Psychological Factors (Pseudo 3D)
Flat images can still suggest depth through monocular cues, but without binocular disparity the result lacks immersion — this is "pseudo 3D."
Popular outdoor angled-LED "3D" billboards rely entirely on psychological depth cues
核心技术原理
📐 柱镜光栅分光技术
基于双目视差和光栅分光原理，无需专用眼镜的前提下，让2D显示屏像素发出的光线，经特殊设计的光学结构（柱状透镜光栅）折射到指定的空间位置，分别被不同位置的人眼（视点）所看到。这是实现裸眼3D显示最常用的光学方案。
👁️ 双目视差与运动视差
双目视差提供深度感知（左右眼看到不同画面），运动视差则让观看者在移动时感受到物体的角度变化（不同位置看到不同角度的立体画面）。燃景显示的光场3D显示同时支持这两种视差效果，提供自然真实的3D观看体验。
⚡ 电子光栅2D/3D切换
通过驱动控制液晶响应，生成可控的光栅结构，动态调节光线传播路径。不同于普通柱镜光栅（物理光栅，固定参数），电子光栅开关可控，可自由切换2D/3D显示状态；光栅关闭后对像素光不再有折射分光现象，<strong>2D分辨率完全无损</strong>。
🔄 实时2D转3D引擎
支持将普通2D内容实时转换为3D格式。对于双视点（眼球追踪）显示，当数据源是3D模型文件时，可实时渲染出人眼所处角度的3D画面，实现模拟光场显示，人眼不仅可看到景深，还可看到移动视差画面—就像在真实空间中围绕物体移动时看到真实立体画面一样。

Glossary
Binocular Parallax
The slight horizontal offset between the images seen by the left and right eyes (due to the ~65 mm interpupillary distance). This is the brain's primary physiological mechanism for depth perception and stereoscopic vision.
Motion Parallax
The apparent shift in position of objects viewed from different angles as the observer moves. Near objects appear to move faster than far ones — as seen from a train window — creating a dynamic depth hierarchy.
Viewpoint
The specific spatial position of an observer's eye — the origin point of the visual ray (line of sight).
Electronic Grating
An electronically controlled liquid crystal structure that can be switched on or off to dynamically steer light paths. Enables instant switching between 2D and 3D modes with zero resolution loss in 2D mode.
Lenticular Lens
A cylindrical lens array — the most common physical grating structure for autostereoscopic displays. Made of transparent resin with precision embossed or etched grating patterns on the surface.
Interleaved Image
A composite image formed by arranging left- and right-eye view pixels in an alternating pattern (e.g., odd/even columns or checkerboard). When viewed through a 3D display's grating, it reconstructs separate images for each eye.
