An integral imaging-based 2D/3D convertible display system is proposed by using a lens-array holographic optical element (LAHOE), a polymer dispersed liquid crystal (PDLC) film, and a projector. The LAHOE is closely attached to the PDLC film to constitute a projection screen. The LAHOE is used to realize integral imaging 3D display. When the PDLC film with an applied voltage is in the transparent state, the projector projects a Bragg matched 3D image, and the display system works in 3D mode. When the PDLC film without an applied voltage is in the scattering state, the projector projects a 2D image, and the display system works in 2D mode. A prototype of the integral imaging-based 2D/3D convertible display is developed, and it provides 2D/3D convertible images properly.
提出了一种基于集成成像的 2D/3D 可转换显示系统，该系统使用透镜列全息光学元件（LAHOE）、聚合物分散液晶（PDLC）膜和投影仪。LAHOE 紧密贴合 PDLC 膜构成投影屏幕。LAHOE 用于实现集成成像 3D 显示。当施加电压的 PDLC 膜处于透明状态时，投影仪投影布拉格匹配的 3D 图像，显示系统以 3D 模式工作。当没有施加电压的 PDLC 膜处于散射状态时，投影仪投影 2D 图像，显示系统以 2D 模式工作。开发了基于集成成像的 2D/3D 可转换显示原型，它可以正确提供 2D/3D 可转换图像。
