Patent ID: 8716931

Claim:
An organic light emitting diode (OLED) display comprising: a substrate main body; an organic light emitting element on the substrate main body; an encapsulation substrate covering the organic light emitting element and coupled to the substrate main body; a translucent insulating layer filter contacting the encapsulation substrate, the translucent insulating layer filter and the encapsulation substrate forming a microcavity; and an air layer between the organic light emitting element and the translucent insulating layer filter, wherein the organic light emitting element comprises a red pixel portion, a green pixel portion, and a blue pixel portion, wherein at least a portion of the translucent insulating layer filter overlaps each of the red, green, and blue pixel portions, wherein the translucent insulating layer filter comprises a same material for the red, the green, and the blue pixel portions, and wherein the translucent insulating layer filter comprises an organic insulating material selected from the group consisting of poly(3,4-ethylenedioxythiophene) (PEDOT); 4,4′-bis[N-(3-methylphenyl-N-phenyl amino)]biphenyl (TPD); 4,4′,4″-tris[(3-methylphenyl)phenyl amino]triphenylamine (m-MTDATA); 1,3,5-tris [N,N-bis(2-methylphenyl-amino]-benzene (o-MTDAB); 1,3,5-tris[N,N-bis(3-methylphenyl-amino]-benzene (m-MTDAB); 1,3,5-tris[N,N-bis(4-methylphenyl)-amino]-benzene (p-MTDAB); 4,4′-bis[N,N-bis(3-methylphenyl)-amino]-diphenylmethane (BPPM); 4,4′-dicarbazolyl-1,1′-biphenyl (CBP); 4,4′,4″-tris(N-carbazol)triphenylamine (TCTA); 2,2′,2″-(1,3,5-benzentolyl)tris-1-[phenyl-1H-benzoimidazol](TPBI); and 3-(4-biphenyl)-4-phenyl-5-t-butylphenyl-1,2,4-triazole (TAZ).
