The study found that the forward voltage of InGaN-based red/green micro-light-emitting diodes was independent of the dimension, red LEDs exhibited a larger blueshift of peak wavelength and broader full-width at half maximum compared to green LEDs. The 47x47 μm² red LEDs showed an on-wafer external quantum efficiency of 0.36% at the peak wavelength of 626 nm, close to the red primary color defined in the recommendation 2020 standard.
We investigated the performance of InGaN-based red/green micro-light-emitting diodes (mu LEDs) ranging from 98 x 98 mu m(2) to 17 x 17 mu m(2). The average forward voltage at 10 A/cm(2) was independent of the dimension of mu LEDs. Red mu LEDs exhibited a larger blueshift of the peak wavelength (similar to 35 nm) and broader full-width at half maximum (>= 50 nm) at 2-50 A/cm(2) compared to green mu LEDs. We demonstrated that 47 x 47 mu m(2) red mu LEDs had an on-wafer external quantum efficiency of 0.36% at the peak wavelength of 626 nm, close to the red primary color defined in the recommendation 2020 standard.
