Toppan Printing has developed and prototyped a new solution-processed TFT using transparent amorphous oxide semiconductor and a low-temperature manufacturing process. Toppan is using this to drive a flexible e-paper - they say that the new technology will enable cheap, light weight and flexible e-papers.
