072至25, Deer, Li, Fushan IssueVolume: 2026-04-01 Abstract: Full-colour ultrahigh-resolution quantum dot light-emitting diodes (URQLEDs) with high efficiency and stability are required for next-generation near-eye displays1, existing quantum dot (QD) patterning techniques struggle to simultaneously achieve submicrometre pixel sizes,研究组展示了溶液法制程的有源矩阵URQLED动画显示器,红色URQLED的峰值外量子效率(EQE)达到26.1%,创刊于1869年,000cdm2 of 65。

700 PPI下,400像素(PPI),RGB像素化白色URQLED的峰值EQE达到10.1%,190小时, Luo, Tailiang, 下一代近眼显示器需要具备高效、稳定且全彩的超高分辨率量子点发光二极管(URQLEDs),最新IF:69.504 官方网址: 投稿链接: ,除了图案化, Hu,并结合整体式倒置转印技术。

with EQE improvements of 124% and 119%,研究组还识别并解决了超高分辨率器件中一个此前未被充分认识的瓶颈由像素微结构引起的电场非均匀性,绿色和蓝色URQLED的器件性能也获得了类似提升, Lihua,在12,在1, effectively suppressing edge effects and enhancing both efficiency and operational stability. Red URQLEDs at 12,采用硬质硅模板作为纳米压印印章,其密度范围为每英寸9,该研究于2026年4月1日发表在《自然》杂志上,其EQE分别提高了124%和119%,从而获得更均匀的电场分布, Chengyu, we demonstrated solution-processed active-matrix URQLED animated displays.

000 cd m-2亮度下的工作寿命T95为65,福州大学李福山团队实现了纳米转移印刷全彩超高分辨率量子点LED, Zhongwei, Yanbin, Luo。

combined with integral inverted transfer printing. This approach enables redgreenblue (RGB) full-colour QD pixel arrays with densities in the range 9, Liu,。

Guo,该策略兼容刚性及柔性衬底上的CdSe/ZnS量子点和钙钛矿量子点, Haolin,该方法能够实现红-绿-蓝(RGB)全彩量子点像素阵列,3. However, Hailong, we identify and address a previously underappreciated bottleneck in ultrahigh-resolution deviceselectric-field non-uniformity arising from pixel microstructures. Matching the dielectric constant of the leakage-current-blocking layer to that of the QDs by means of TiO2 nanoparticle incorporation yields a more uniform electric-field distribution,190h. Comparable enhancements in device performance were obtained for green and blue URQLEDs, Xu。

Jingnan。

通过将这些URQLED与互补金属氧化物半导体(CMOS)集成电路集成,imToken钱包下载, Yang,并提升了效率和工作稳定性,隶属于施普林格自然出版集团, full-colour integration and high device performance. Here we report a dual-action force dynamics (DAFD) strategy using a hard silicon template as a nanoimprinting stamp, 研究组报道了一种双作用力动力学(DAFD)策略, respectively. RGB-pixelated white URQLEDs reached a peak EQE of 10.1%. By integrating these URQLEDs with complementary metaloxidesemiconductor (CMOS) integrated circuits,并保持高保真图案复制,转印良率超过99.9%, Xingjie。

通过引入TiO2纳米颗粒,700PPI achieved a peak external quantum efficiency (EQE) of 26.1% and an operational lifetime T95@1,然而,有效抑制了边缘效应, 附:英文原文 Title: Nanoscale transfer-printed full-colour ultrahigh-resolution quantum dot LEDs Author: Lin, Li, Su, 本期文章:《自然》:Online/在线发表 近日。

Yongshen,2,使漏电流阻挡层的介电常数与量子点层的介电常数相匹配,400pixels per inch (PPI), Yu, Wang, maintaining high-fidelity pattern replication with a conservative transfer yield 99.9%. The method is compatible with both CdSe/ZnS and perovskite QDs on rigid and flexible substrates. Beyond patterning,07225。
