Patent ID: 8153352

Claim:
A process for forming a pixel circuit, comprising: a) providing a transparent support having a first side; b) forming a multicolor mask having at least four different color patterns; and c) forming integrated electronic components of the pixel circuit having at least four layers of patterned functional material comprising a first conductor, a dielectric, a semiconductor, and a second conductor each layer of patterned functional material corresponding to said at least four different color patterns of the multicolor mask, each layer of patterned functional material formed by: i) coating a layer of a photopatternable material sensitive to visible light on the first side of the transparent support after forming the multicolor mask; ii) exposing the layer of photopatternable material through the multicolor mask with visible light to form a photopattern corresponding to one color pattern of said color patterns of the multicolor mask, wherein the photopattern is composed of photopatternable material in a second exposed state that is different from a first as-coated state; iii) depositing a layer of a functional material before or after coating the photopatternable material; and iv) patterning the functional material using the photopattern such that the resulting patterned functional material corresponds to said one color pattern; wherein the multicolor mask comprises: i) a first color pattern corresponding to the first conductor, wherein a color portion of the first color pattern comprises a negative copy of the first conductor's pattern; ii) a second color pattern corresponding to the dielectric, wherein a color portion of the second color pattern comprises a positive copy of the dielectric's pattern; iii) a third color pattern corresponding to the semiconductor, wherein a color portion of the third color pattern comprises positive copy of the semiconductor's pattern; and iv) a fourth color pattern corresponding to the second conductor, wherein a color portion of the fourth color pattern comprises a positive or negative copy of the second conductor's pattern.
