Film electrostatic light modulators using nanostructured inks

First experimentation on film electrostatic spatial light modulators is reported. As an alternative to conventional photolithography and thin film technologies used to make microshutters-micromirrors, we propose a screen printed multilayer deposition with control of the electromechanical features of each layer by a proper preparation of the inks. A possible way to replace the use of expensive indium tin oxide (ITO) for the transparent electrode is discussed. In particular a cheap printed layer, based on nanostructured inks, is proposed. chnology of film electrostatic light modulators can be used in display applications as a substitute for LCDs. An example in an automotive instrument cluster is presented.
