Abstract

We have developed a 2 inch LTPS-TFT AMOLED display with a top emission structure on a $50-{\mu}m-thick$ metal foil. The Active matrix back planes were fabricated with the p-channel LTPS TFT with a conventional pixel circuit consisting of 2 transistors and 1 capacitance. The p-channel TFTs on the metal foil exhibited the field-effect mobility of $22cm^2/Vs$. Finally, a images from prototype monochrome AMOLED displays are successfully presented, with $64{\times}88$ pixels and 56-ppi resolution.
