Transparent flexible displays can be realized using active matrix organic light emitting device (AMOLED) with transparent electrodes on transparent plastic substrates. In this study, we developed low-temperature, high-performance [ZITO, ZnO : In2O3 : SnO2 = 3 : 1 : 1 molar ratio] thin-film transistors (TFTs) on polyarylate films. After optimizing the sputtering condition, the ZITO TFT with an ITO electrode had a high mobility of 16.93 cm2 V-1 s-1, and an SS of 0.39, while the ZITO TFT with a ZTO:B electrode showed no hysteresis on sweeping, a mobility of 2.29 cm2 V-1 s-1 and an SS of 0.18. © 2010 The Japan Society of Applied Physics.

We have prepared ZnO TFT driving color AMEPD using nanoscale electrophoretic ink particles made by invented modified emulsion process. New concept of color filter using silver halide technology - similar with photographic technology which is suitable for reflective EPD application was adapted to develop color filters. To get rid of align process for color filters and TFT arrays, transparent ZnO TFT with low temperature process was fabricated. In case of monochrome EPD, the contrast ratio was 23:1 at operating voltage of ± 10V. Zone color prototype AMEPD was fabricated with silver halide color filter. Source
