We demonstrated $10\times 10$ arrays of InGaN $17\mathrm{\mu m}\times 17\mathrm{\mu m}$ micro-light-emitting diodes (μLEDs) with a peak wavelength from 662 to 630 nm at $10–50\mathrm{A}/{\mathrm{cm}}^2$. The on-wafer external quantum efficiency reached 0.18% at $50{\mathrm{A}/\mathrm{cm}}^2$. The output power density of the red μLEDs was obtained as $1.76{\mathrm{mW}/\mathrm{mm}}^2$, which was estimated to be higher than that of $20\mathrm{\mu m}\times 20\mathrm{\mu m}$ AlInGaP red μLEDs ($\sim 630\mathrm{nm}$). Finally, we demonstrate that InGaN red/green/blue μLEDs could exhibit a wide color gamut covering 81.3% and 79.1% of the Rec. 2020 color space in CIE 1931 and 1976 diagrams, respectively.

630nm 红色 InGaN 微型发光二极管（<20 μm × 20 μm）超过 1 mW/mm2 用于全彩微型显示器

我们展示了 $10\times 10$ InGaN 阵列 $17\mathrm{微米}\times 17\mathrm{微米}$ 峰值波长为 662 至 630 nm 的微型发光二极管 (μLED) $10\mathrm{——}50\mathrm{一种}/{\mathrm{厘米}}^2$. 晶圆外量子效率达到 0.18%$50{\mathrm{一种}/\mathrm{厘米}}^2$. 红色 μLED 的输出功率密度为$1.76{\mathrm{兆瓦}/\mathrm{毫米}}^2$，估计高于 $20\mathrm{微米}\times 20\mathrm{微米}$ AlInGaP 红色 μLED（$～630\mathrm{纳米}$）。最后，我们证明了 InGaN 红/绿/蓝 μLED 可以表现出覆盖 Rec 81.3% 和 79.1% 的宽色域。分别为 CIE 1931 和 1976 图中的 2020 色彩空间。
