Abstract

Official abstract text for this publication.

An organic light emitting display apparatus including sub pixels, each of the sub pixels including: first and second electrodes, the second electrode extending over the first electrode; and an intermediate layer disposed between the first and second electrodes, the intermediate layer including an emission layer, wherein a first portion of the first electrode, the second electrode, and the intermediate layer extends within a weak resonance region, the weak resonance region being configured to induce a first resonance of light generated by the emission layer between the first and second electrodes, and a second portion of the first electrode, the second electrode, and the intermediate layer extends within a strong resonance region, the strong resonance region being configured to induce a second resonance of light generated by the emission layer between the first and second electrodes, the second resonance being stronger than the first resonance.

First claim

Opening claim text (preview).

What is claimed is: 1. organic light emitting display apparatus comprising a plurality of unit pixels, each unit pixel having at least two sub pixels, a first one of the sub pixels to emit only a first color of light and a second one of the sub pixels to emit only a second color of light, the first and second colors of light being different colors of light, and each of the at least two sub pixels including: a first resonance region; a second resonance region; first and second…
