ABSTRACT:
A tandem OLED device having two spaced electrodes comprising: first and second light-emitting units that produce different emission spectra disposed between the electrodes, the first light-emitting unit produces light that has multiple peaks at wavelengths longer than 500 nm and substantially no emission at wavelengths shorter than 480 nm, and the second light-emitting unit produces light that has substantial emission at wavelengths shorter than 500 nm; and an intermediate connector disposed between the light-emitting units.
