Summary:There is provided a backplane for an organic electronic device including a TFT substrate having a base substrate, a polysilicon layer, a gate dielectric layer, a gate electrode, an interlayer dielectric, and a data electrode; an insulating layer over the TFT substrate; a multiplicity of first openings in the insulating layer having a depth d1; a multiplicity of pixelated diode electrode structures, wherein a first set of diode electrode structures are in the first openings; and 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.
