Image Pickup Demonstration Using Stacked Structure of Organic Photoconductive Films and ZnO TFTs

Abstract

In order to achieve compact Super Hi-Vision color camera without the color separation optical systems, we have been developing a new type of image sensor with three organic photoconductive films sensitive to red(R), green(G) and blue(B). In this paper, we fabricated a stacked organic image sensor with G and R sensitive organic photoconductive films, each of which had readout circuit of zinc oxide (ZnO) thin film transistor (TFT). We successfully demonstrated an image pickup at TV flame rate. The sensor produced a color image with a resolution corresponding to the pixel number of ZnO TFT.
