Abstract

In this paper we present results on the optimization of device architectures for colour and imaging applications, using a device with a TCO/pinpi'n'/TCO configuration. A set of different devices with different intrinsic back layers are analysed.

The effect of the applied voltage on the color selectivity is discussed. Results show that the spectral response curves demonstrate rather good separation between the red, green and blue basic colors. Combining the information obtained under positive and negative applied bias a colour image is acquired without colour filters or pixel architecture. A low level image processing algorithm is used for the colour image reconstruction.
