6、，可观看舒适的3D影响。2、可视角度广，可在任何角度观察，3D效果不打折扣。3、无拖拉现象产生，可实现240Hz3D影响。缺点：缺点：3D效果略逊于其它同类产品。裸眼式裸眼式 3D：光屏障式光屏障式 优势：优势：与LCD液晶工艺兼容，因此在量产性和成本上较具优势。缺点：缺点：画面亮度低，分辨率会随着显示器在同一时间播出影像的增加呈反比降低。柱状透镜柱状透镜 优点：优点：3D技术显示效果更好，亮度不受到影响 缺点：缺点：相关制造与现有LCD液晶工艺不兼容，需要投资新的设备和生产线。Active Shutter 3D裸眼 3D33D Differentiated StrategyPolarizat

8、出频率满足120Hz就可以导入，而是要在整张Panel上贴附一层FPR 用于将屏幕发出的非偏振光变成偏振光，从而产生3D效果。FPR贴附精度要求高，与像素点对位中间70um，两边120um时间分割方式能保证画面分辨率不变，但是需要提高率刷新频率至正常的2倍。空间分割方式与时间分割优缺点正好相反，不用改动刷新频率，分辨率降低一半。偏振式3D技术色彩小，颜色更为接近原始值。观看视角广，倾斜一定角度仍能看到高品质的3D画面效果。2009 AMB Property Corporation 5不用对Cell本身做修改，结构简单对不透镜精度要求高观测视角小，分辨率低3D Differentiated St

9、rategy在Panel前放置柱状透镜，通过光线入射角度不同，折射不同的角度后分别为左右眼所接收，呈现3D显示效果屏幕亮度不会改变，但是分辨率等同于视差式会降低一半。观看视角小，移动会产生串扰现象，3D效果一般成本高于视差式。E:P=D:GQ:D=2P(D+G)结构简单，易进行改造。改造成本低亮度低，分辨率差，可视角度小视差挡板就是在光路加上一些遮蔽物，把部分方向的光遮住，只让某些角度的光可以传出去，人眼观测角度小，不能移动观看。挡板的位置经过精密计算，可以左眼像素（绿色）只被左眼看到，右眼像素（红色）只被右眼看到。观察位置偏移会产生串扰现象。柱透镜式裸眼柱透镜式裸眼3D视差挡板式裸眼视差挡板

12、最多能显示10亿个像素点，为了减少死区，加入了中继转向器等精密光学仪器，成本大幅升高，设备制作难度大。激光的扫描速度有限，导致显示画面的容量叫小，无法完成高精度复杂画面显示。色彩单一，无法显示很复杂的彩色画面。平板旋转屏的清晰度受限，像素点在三维空间分布不均匀。3D Differentiated StrategyActive Shutter 3D 详解详解 2009 AMB Property Corporation 8利用高频载波信号实现红外信号的传输，确保时序稳定发射器每一周期发送一次红外信号，眼镜接收一次信号，左右眼各获取一张图片。需要电视或者充电重量较大红外或蓝牙传输方式视角较小佩戴时间
