NHK Researches Organic Image Sensors

Tech-On: Japan Broadcasting Corp (NHK) Science & Technical Research Laboratories exhibited an organic color image sensor along with images recorded by the sensor at its Open House 2008.

The image sensor is has three photosensitive layers stacked one on another. Each of the layers includes a colored organic semiconductor and a transparent zinc oxide (ZnO) TFT. By using different organic semiconductors for the three layers, each of them is designed to absorb one of R,G or B colors.

The first prototype that was made only a week ago and has resolution of 47x30. However, NHK researches hope that one day it would compete with Super Hi-Vision video sensors with resolutions up to 7680 x 4320.


  1. Why do I think I saw a prototype of this in 2005 at NHK?

  2. They published similar work in 2005

  3. Thank you for the link. Looking on the abstract, the 2005 claims appear to be the same as 2008's ones.
