Advanced Integration of RGB MicroLEDs Enabled by Micro-Transfer Printing

Description:

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.
