Abstract

A process for forming a pixel circuit is disclosed comprising: (a) providing a transparent support; (b) forming a multicolor mask having at least four different color patterns; (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 the four different color patterns of the multicolor mask. The functional material is patterned using a photopattern corresponding to each color pattern.
