3D显示技术已成为目前显示领域的发展趋势， 3D 显示技术可以使画 面变得立体逼真， 图像不再局限于屏幕的平面上， 仿佛能够走出屏幕外 面， 让观众 身临其境的感觉。 目前， 3D 显示技术一般是采用双目视差 即将两幅视差图像 （即左、 右视差图像）显示在二维显示屏
J^「 后利用一定的技术使观看者的左， 右眼分别只能看到二维显示屏上 的左、 右视差图像。
3D 显示技术分类可以分为眼镜式和棵眼式两大类。 而， 现有的液晶 显示器 ( Liquid Crystal Display, LCD )棵眼 3D显示技术有两种: 光屏障式 3D 显示技术的实现方法是使用一个开关液晶屏， 偏振膜和 高分子液晶层， 利用高分子液晶层和偏振膜制造出一系列方向为 90°的垂 直条纹。 这些条紋宽儿十微米， 通过它 ^的光就形成了垂直的细条柵模 式， 称之为 "视差障壁" 。 而该光屏障式 3D 显示技术正是利用了安置在 3 光模块及液晶显示面: ：壁， 在立体显示模式下， 应该由左眼 同理， 应该由 通过将左

影像。 这种技 术成本比较低， 但屏幕亮度偏低。
柱状透镜技术也被称为微柱透镜 3D显示技术， 使液晶屏的像平面位 于透镜的焦平面上， 这样在每个柱透镜下面的图像的像素被分成几个子像 素， 这样透镜就能以不同的方向投影每个子像素。 于是双眼从不同的角度 观看显示屏， 就看到不同的子像素， 以形成 3D效果。 这种 3D显示技术 显示效果更好， 亮度也不受到影响， 但其相关制造工艺与现有的液晶显示 器的液晶工艺不兼容， 需要投资开发新的设备和生产线。
