提出了一种大尺寸、柔性、透明的3D平视显示器。一个实际的3D曲面显示器的大小为20厘米× 20厘米，能够重建3D场景的深度为5厘米，从显示器在20度的视角已经实现。这是一种光场型显示系统，其仅需要商业投影仪和全息屏幕来工作。全息屏幕是数字印刷的体全息图，其包括诸如微透镜阵列、垂直倾斜和水平弯曲的多个功能。单个全息屏幕上的这些多个功能有助于克服实现大尺寸和灵活的3D光场显示器中的几个主要问题。
A large-size, flexible and see-through 3D head-up display is presented. A practical 3D curved display of size 20cm x 20cm capable of reconstructing 3D scenes upto a depth of 5cm from the display at viewing angle of 20-degrees has been realized. This is a light field type display system which requires only a commercial projector and hologram screen for its working. The hologram screen is a digitally printed volume hologram which includes multiple functions such as, micro lens array, vertical tilt and horizontal curvature. These multiple functions on a single hologram screen assists in overcoming several major issues in realizing large-size and flexible 3D light field displays.
