| 摘要 |
A full color electroluminescent display is disclosed, the display including a common substrate and an array of electroluminescent devices disposed on the common substrate, wherein each of said electroluminescent devices comprises an electroluminescent layer that is sandwiched between a first and a second electrode, a color converting material that is capable of changing light emitted by the electroluminescent layer into light having a longer wavelength and a stack of 2n+1 transparent dielectric layers wherein n=0, 1, 2, 3, . . . and said transparent dielectric layers show alternating refractive indexes n. The electroluminescent display shows improved light outcoupling.
