The patented MicroLED (µLED™) is formed by the integration of light control optics directly at the site of light generation. This is done during the fabrication process and is the most efficient position to place this device.
This optical component results in a high extraction efficiency and all the light exiting through a single surface of the LEDs.
Figure 1 (below) gives an example of the light extracting structure.
The MicroLED ( µLED) is optimised for flip-chip mounting. This results in excellent heat-sinking of the device and reduced thermal effects in the light source.
