Inorganic Printed Electronics – The Great Opportunity

Inorganic compound transistors driving flexible displays
Last year, Toppan Printing in Japan demonstrated a flexible electrophoretic display back plane driver employing amorphous indium gallium zinc oxide semiconductors processed at room temperature. This is based on work at Tokyo Institute of Technology in Japan. Toppan Printing claims much higher mobility and therefore potentially higher frequency of operation than organic alternatives. Both companies have programs to commercialize their inventions though Plastic Logic of the UK is ahead with flexible electrophoretic displays because it is already building a factory in Dresden in Germany to make them using its organic transistors.
