Patent ID: 7420205

Claim:
An electronic device comprising: a substrate; a continuous first layer comprising a host material overlying the substrate, wherein: the continuous layer comprises a first portion in which an electronic component lies and a second portion where no electronic component lies; the first portion includes a first guest material; the first guest material is intermixed with the first host material to form intermixed regions in the first portion of the first continuous layer; and each intermixed region is thicker than the second portion of the continuous layer where no intermixed regions are formed; wherein the continuous first layer is (1) capable of emitting radiation having an emission maximum at a targeted wavelength or within a targeted spectrum of wavelengths or (2) designed to respond to radiation at a targeted wavelength or within a targeted spectrum of wavelengths, wherein the targeted spectrum has a width no greater than 150 nm; and the first guest material is (1) capable of emitting radiation having an emission maximum at a targeted wavelength or a targeted spectrum of wavelengths or (2) designed to respond to radiation at a targeted wavelength or within a targeted spectrum of wavelengths; wherein each of the continuous first layer and the first guest material has an emission maximum within a blue light spectrum, wherein: the continuous first layer includes additional first portions; the electronic device includes first electronic components; each of the first electronic components comprises a first electrode, a second electrode, and at least one of the first portions lying between the first and second electrodes; and wherein: the continuous first layer includes third portions and fourth portions; the third portions include a second guest material; the fourth portions include a third guest material; the electronic device includes second electronic components and third electronic components; each of the second electronic components comprises a third electrode, a fourth electrode, and at least one of the second portions lying between the third and fourth electrodes; each of the third electronic components comprises a fifth electrode, a sixth electrode, and at least one of the third portions lying between the fifth and sixth electrodes; the second guest material is intermixed with the host material in the third portions of the continuous first layer to form second intermixed regions; the third guest material is intermixed with the host material in the fourth portions of the continuous first layer to form third intermixed regions; each intermixed region has a thickness greater than that of the second portion of the continuous layer where no intermixed regions are formed.
