用于2D/3D可切换显示的变焦透镜阵列技术

摘要：

随着显示技术的快速发展，2D与3D显示技术各具特色。在需要呈现标签、文本等细节信息时，2D显示凭借其高分辨率和清晰度的优势成为理想选择；而在观看电影、虚拟现实体验或复杂场景模拟等场景下，3D显示技术能够提供更丰富的空间维度信息，带来更佳的沉浸式体验。2D/3D可切换显示系统通过独立控制两种显示模式，为用户提供了灵活多样的个性化使用体验。聚氯乙烯（PVC）凝胶作为一种具有优异柔软性和高透明度的电活性聚合物材料，展现出独特的优势。在直流电场作用下，PVC凝胶能够向阳极发生蠕变变形，这一特性使其成为制作变焦透镜的理想光学材料。与传统液晶透镜相比，PVC凝胶透镜具有无偏振依赖性、光学透过率高等显著优势；相较于液体透镜，其稳定性更佳且无重力效应影响。基于PVC凝胶的透镜结构紧凑、制备工艺简单、成本低廉，这些特点使其在2D/3D可切换显示领域具有广阔的应用前景。然而，PVC凝胶透镜的实际应用面临一个关键挑战：较高的驱动电压需求限制了其大规模应用。针对这一问题，研究者通过精确调控离子液体的结构和含量，显著降低了PVC凝胶柱透镜阵列的驱动电压。实验结果表明，基于PVC凝胶柱透镜阵列的显示系统能够实现2D/3D显示效果的稳定切换，为该技术的进一步推广奠定了基础。

Title

Focus-tunable microlens array for 2D/3D swithable displays

Abstract：

With the rapid development of display technology, 2D and 3D display technologies have their unique advantages. In scenarios where labels, text, or detailed information need to be presented, 2D displays are an ideal choice due to their high resolution and clarity. On the other hand, 3D display technology excels in providing richer spatial information, offering an enhanced immersive experience for applications such as watching movies, virtual reality experiences, or simulating complex scenes. The 2D/3D switchable display system allows independent control of both display modes, providing users with flexible and diverse personalized experiences.

In the field of optical materials, polyvinyl chloride (PVC) gel stands out as an electroactive polymer material with excellent flexibility and high transparency. Under the influence of a direct current electric field, PVC gel exhibits creep deformation toward the anode, making it an ideal material for fabricating variable-focus lenses. Compared with traditional liquid crystal lenses, PVC gel lenses have significant advantages, including polarization independence and high optical transmittance. Furthermore, unlike liquid lenses, PVC gel lenses demonstrate superior stability and are unaffected by gravitational effects. Additionally, lenses based on PVC gel are compact in structure, easy to fabricate, and cost-effective, making them highly promising for applications in 2D/3D switchable display systems.

However, the practical application of PVC gel lenses faces a critical challenge: the high drive voltage required limits their large-scale implementation. To address this issue, researchers have precisely regulated the structure and content of ionic liquids, significantly reducing the drive voltage of PVC gel column lens arrays. Experimental results demonstrate that a display system based on PVC gel column lens arrays can achieve stable switching between 2D and 3D display effects, laying a solid foundation for the further promotion of this technology.
