Electroluminescent QDEL devices with heavy metal free InP and ZnTeSe quantum dots are one of the most promising future display technologies. Here we report improved efficiency of 19.6%, 17.6%, and 12.7% for red, green, and blue QDEL devices, respectively. The blue QDEL devices exhibit true blue emission with peak wavelength of 453 nm.
