Microled eqe
WebAug 19, 2024 · The peak value of EQE reached 5%, reported in Ref. for 10-μm-pixel MicroLED. Meanwhile, its peak EQE also appeared at the current density of around 30 A/cm 2. Moreover, Templier also reported the 6.5 μm × 6.5 μm blue MicroLED has a maximum EQE of 9.5%, obtained at a current density of 20 A/cm 2 (or 25 μA). WebEQE of 0.2% at a current density of 10 A/cm2 with a peak emission wavelength of 632 nm [14]. To our knowledge, this on-wafer EQE is the highest reported value for InGaN red µLEDs. Recently, a high wall-plug efficiency (WPE) of 16.8% at 621 nm was obtained at 0.8 A/cm2 for 1×1 mm2 InGaN-based LEDs [15]. This WPE value was
