White-emitting organic electroluminescent device with color filters and reflective layer for causing colored light constructive interference

摘要

A multicolor organic light-emitting display having an array of pixels having at least two different colors including a substrate; a reflective layer disposed over the substrate; and a first transparent electrode disposed over the reflective layer. The display also includes a second transparent electrode spaced from the first transparent electrode and an organic EL media disposed between the first and second transparent electrodes and arranged to produce white light. The display further includes at least first and second filters of different colors disposed respectively over different predetermined pixels of the array, and wherein the thickness of the first transparent electrode is separately adjusted for each different color to cause a substantial amount of the reflected component of colored light corresponding to its associated color filter to constructively interfere with a substantial amount of the non-reflected component of colored light corresponding to its associated color filter.
