With the advancement of light‐emitting diode (LED) display technologies, optical crosstalk has emerged as a significant challenge due to the increasing miniaturization and pixel density of LED arrays. To address this issue, the introduction of a nanorod (NR) optical shield in LED devices is proposed. The shield is fabricated using a straightforward process involving the etching of LED epitaxial layers with self‐assembled Ni nanoparticles and a SiO2 hard mask, resulting in the formation of an NR array. The NR optical shield effectively reduced optical crosstalk by confining light emission to its region, redirecting lateral light into vertical emission and absorbing stray light. This approach offers a practical and efficient solution for reducing optical crosstalk and enhancing the performance of miniaturized LED arrays in advanced display applications.
