Acreo, in collaboration with Linköping University, are developing low-cost electronics printed on paper. Their focus is on electrochemical devices, such as electrochromic displays. The change between bright and dark state is based on the difference in absorbtion of a polymer, e.g. PEDOT:PSS, in the oxidised versus the reduced state. Switching occurs at low voltages [...]

The New Scientist is reporting on flexible electrochromic displays developed by Siemens: The display consists of a layer of electrochromic material sandwiched between two electrode layers. The material changes from one colour to another when stimulated by an electric current. The top electrode layer is made from transparent plastic, so the display can be seen clearly [...] Aveso, Inc. [formerly known as Commotion solutions], a recent spin-out from The Dow Chemical Company, announced today its entry into the $50-billion electronic display market. Aveso is developing paper-thin microelectronic devices that feature the company’s proprietary printed electronic display technology integrated with [...] This article by IDTechEX on low-cost display technologies talks about Ntera’s NanoChromic Display (NCD): At the heart of this NCD is an electrochromic material, which is normally transparent but turns blue when a negative charge is applied. It requires no moving parts, making NCDs unique among other electronic paper technologies, such as electrophoretic displays. [...] |
