不需要佩戴设备的裸眼三维(3D)显示技术是未来发展的必然趋势。本文提出了一种基于微结构的柔性裸眼3D显示薄膜元件的设计和制作，以实现高分辨率的3D显示效果。该薄膜元件由两套关键微结构组成，即微图像阵列(MIA)和微透镜阵列(MLA)。通过建立基本结构模型，研究了两组微观组织之间的匹配关系。提出了一种基于3D图形软件的三维物体信息采集模型，实现了从不同角度的高分辨率MIA，记录无串扰。此外，还利用光刻技术实现了MLA和MIA的制作。以纳米压印技术为基础，在柔性薄膜衬底上形成了一套完整的集成技术。最后制作了一种重量轻、可卷曲的柔性3D显示薄膜元件。
The naked-eye three-dimensional (3D) display technology without wearing equipment is an inevitable future development trend. In this paper, the design and fabrication of a flexible naked-eye 3D display film element based on a microstructure have been proposed to achieve a high-resolution 3D display effect. The film element consists of two sets of key microstructures, namely, a microimage array (MIA) and microlens array (MLA). By establishing the basic structural model, the matching relationship between the two groups of microstructures has been studied. Based on 3D graphics software, a 3D object information acquisition model has been proposed to achieve a high-resolution MIA from different viewpoints, recording without crosstalk. In addition, lithography technology has been used to realize the fabrications of the MLA and MIA. Based on nanoimprint technology, a complete integration technology on a flexible film substrate has been formed. Finally, a flexible 3D display film element has been fabricated, which has a light weight and can be curled.
