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.
对提高分辨率的需求催生了具有纳米级像素的显示概念；也就是说，每个子像素由多个甚至单个纳米光源组成，纳米光源被认为是光场、近眼和可植入显示器的终极光源。然而，相关研究仍处于早期阶段，应该对这一未来显示概念提供更多的见解。在本观点中，我们为这一未来显示提出了我们建议的术语，即纳米像素发光显示（NLED）。我们概述了被认为是 NLED 核心组件的纳米发光二极管。然后，提供了一条从材料设计角度实现 NLED 的路线图。最后，我们介绍了我们为 NLED 提出的操作模式（无电接触和无载流子注入模式），并推荐了可能的纳米像素级驱动方法。我们希望本观点有助于设计创新的显示技术。
