Abstract
Micro‐displays using RGB micro‐LEDs grown on Si substrates, each colour based on InGaN materials were developed. To improve the forward emission, micro‐LEDs are integrated onto reflective cavities coupled with microlenses, which enables engineering of far field patterns. We also demonstrated 2‐sided connections to the LEDs on glass substrates through either wrap‐around electrodes or through‐holes, to facilitate more compact packaging and enable seamless large displays.
