Managing the emission properties of microLEDs through photonic bandgap engineering

Application Note

Microscopic light-emitting diode arrays (microLEDs) are predicted to revolutionize the display technology market with boundless applications in portable electronics and wearable displays such as augmented reality headsets. MicroLEDs offer higher resolution and lower power consumption than traditional display technologies due to avoiding power losses associated with color conversion using phosphors. Recent development trends have seen microLED arrays evolve into close-packed three-dimensional structures that introduce photonic crystal (PhC) effects enabling researchers greater control of light emission properties. Novel optical devices employing photonic crystals and metamaterials have an abundance of potential applications which may be utilized to enhance microLED display technologies. PhCs and metamaterials take advantage of coherent scattering and near-field interactions, modifying microLED emission intensity and controlling the emission pattern(s).
