对提高分辨率的要求催生了纳米级像素显示器的概念；也就是说，每个子像素由多个甚至单个纳米光源组成，这被认为是光场、近眼和植入式显示器的终极光源。然而，相关研究仍处于早期阶段，应该对这种未来的显示概念提供进一步的见解。在本视角中，我们为这种未来显示器提出了术语，即纳米像素发光显示器（NLED）。我们概述了纳米发光二极管，它被认为是 NLED 的核心组件。然后，提供了从材料设计角度实现 NLED 的路线图。最后，我们介绍了我们提出的 NLED 操作模式（非电接触和非载流子注入模式），并推荐了可能的纳米像素级驱动方法。我们希望这一观点对设计创新的显示技术有所帮助。
The requirement for increased resolution has created the concept of displays with nanoscale pixels; that is, each subpixel consists of multiple or even a single nanolight source, which is considered the ultimate light source for light field, near-eye, and implantable displays. However, related research is still at an early stage, and further insights into this future display concept should be provided. In this Perspective, we provide our proposed term for this future display, namely, nanopixel light-emitting display (NLED). We present an overview of nanolight-emitting diodes, which are considered the core component of NLEDs. Then, a roadmap to realize NLEDs from the view of material design is provided. Finally, we introduce our proposed operation mode (nonelectrical contact and noncarrier injection mode) for NLEDs and recommend possible nanopixel-level drive approaches. We hope that this Perspective will be helpful in designing innovative display technologies.
