HIGH-PERFORMANCE TANDEM WHITE OLED

摘要

A tandem OLED device having two spaced electrodes (30,90) comprising: first and second light-emitting units (70,80) that produce different emission spectra disposed between the electrodes, the first light-emitting unit (80) produces light that has multiple peaks at wavelengths longer than 500 nm and sustantially no emission at wavelengths shorter than 480 nm, and the second light-emitting unit (70) produces light that has sustantial emission at wavelengths shorter than 500 nm,- and an intermediate connector (95) disposed between the light-emitting units.
