Wafer Bonding Technology
The MED7P14 and MED7P14C have improved the extraction efficiency of light by attaching a metal mirror to the lower layer of the emitting layer. They achieve twice the light output compared to previous products. Furthermore, we have developed the MED7P25, which offers even higher light output.
