Toppan Printing developed new technology that promises cheap and flexible e-paper displays

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. 

Toppan is showing a 2" x 2" prototype, with a 80x60 resolution. The TFT substrate is made of glass, and the semiconductor material is a transparent amorphous oxide semiconductor.
