Novel Image Sensor Using Organic Photoconductive Films

Abstract

We have been studied a new type of solid state image sensor with vertically stacked structures of three organic photoconductive films which are sensitive to only red, green and blue light, with the aim of developing high-resolution compact color cameras without color separation optical systems. In this paper, we describe organic photoconductive films sensitive to each primary color component with changing organic molecules, image pickup using an organic film incorporated into a camera tube, and the operation of a CMOS readout circuit overlaid with an organic film, showing the great potentials for the development of highresolution prism-less color cameras.
