Printed Multi-color Devices using Oxidative Electrochromic Materials

We developed new oxidative electrochromic materials based on triarylamines and benzidine. These were coated onto substrates and cured by UV irradiation to obtain polymer films. These materials emitted yellow, magenta and cyan colored light. In color devices using these materials, high transmittances...

Summary:We developed new oxidative electrochromic materials based on triarylamines and benzidine. These were coated onto substrates and cured by UV irradiation to obtain polymer films. These materials emitted yellow, magenta and cyan colored light. In color devices using these materials, high transmittances of the uncolored states and high optical densities of the colored states were shown to be compatible. We demonstrated that CMYK and RGB can be expressed by mixing these materials. We also succeeded in prototyping EC decorative glass by combining these materials and using inkjet printing; this represents a new application for oxidative EC materials.
