高生产率 microLED (mu-LED) 像素面板的开发作为下一代显示器的关键技术至关重要。为了提供实现这一目标的基本方法，在本研究中，具有 5 x 5 μ m(2) 发射窗口的多色（红、绿、蓝和黄；RGBY）纳米柱 (NC) mu-LED 像素被单片集成，以显示峰值波长分别为 478、512、559 和 647 nm 的电致发光光谱。 NC mu-LED 像素以 10 μm 周期二维排列，由矩阵布线 p 电极和 n 电极单独驱动，呈现出 mu-LED 像素面板排列。 (c) 2019 日本应用物理学会
The development of high-productivity microLED (mu-LED) pixel panels is crucial as a key technology for next-generation displays. To provide a fundamental approach to this end, in this study, multicolor (red, green, blue, and yellow; RGBY) nanocolumn (NC) mu-LED pixels with 5 x 5 mu m(2) emission windows were monolithically integrated to exhibit electroluminescence spectra with peak wavelengths of 478, 512, 559, and 647 nm, respectively. The NC mu-LED pixels, which were two-dimensionally arranged with a 10 mu m period, were individually driven by the matrix wiring p- and n-electrodes, exhibiting a mu-LED pixel panel arrangement.
