Patent ID: 8772774

Claim:
A backplane for an organic electronic device comprising: a TFT substrate; an insulating layer over the TFT substrate; a multiplicity of first openings in the insulating layer having a depth d 1 ; a multiplicity of pixelated diode electrode structures, wherein a first set of diode electrode structures are in the first openings, and the first set of diode electrode structures is less than the total number of diode electrode structures; a bank structure defining pixel areas over the diode electrode structures; wherein the first openings and first set of diode electrode structures are in at least a first set of the pixel areas, further comprising a multiplicity of second openings in the insulating layer having a depth d 2 , wherein a second set of diode electrode structures are in the second openings, and the second openings are in a second set of pixel areas, wherein d 1 is different from d 2 .
