摘要
提出一种用于二维(2D)/三维(3D)可切换显示的可变焦的柱状液体透镜阵列,主要包含两种不同折射率的透明液体:液体1和液体2,液体1和液体2被透明的弹性薄膜隔离开,弹性薄膜由微支板阵列来支撑。通过外力驱动两种液体在器件内的流动来实现并调节弹性薄膜的形变,弹性薄膜形变有平面形态和可变柱面形态两种,实现该柱状液体透镜阵列焦距从无穷大到有限正焦距的大范围的变焦。实验制作出适用于2D/3D 切换显示器的样品,实验结果验证了其变焦性能,该样品与匹配的平板显示器能进自由立体3D 显示,而且弹性薄膜能变为平面形态用于普通的2D 显示,实现了2D/3D 切换显示。
Abstract
A tunable cylindrical liquid lens array for two dimensional (2D)/three dimensional (3D) switchable display is proposed. It mainly contains two transparent liquids of different refractive index: liquid 1 and liquid 2. Liquid 1 and liquid 2 are divided by a transparent elastic membrane. The elastic membrane is supported by a micro-clapboard array. Driving these two liquids to flow and the support of micro-clapboard array can change the shape of the elastic membrane, then, the membrane has two shapes as flat shape and tunable cylindrical shape. The focal length of tunable cylindrical liquid lens array extensively adaptive from infinity to a certain positive value is realized. A tunable cylindrical liquid lens array prototype for 2D/3D switchable display is developed. The experimental result proves the prototype′ s tunable focus length ability. The prototype with a matched flat display panel realizes autostereoscopic 3D display, moreover, the elastic membrane can change to flat for regular 2D display. Therefore, 2D/3D switchable display is realized.
