A color AM‐OLED display device was fabricated on a plastic substrate using SUFTLA technology, which makes it possible to transfer a thin film device from an original substrate to another, combining ink‐jet printing technology. An LTPS‐TFT circuit of a 5.3cm diagonal OLED display was transferred onto a plastic substrate, and then color OLED display was assembled using inkjet printing technique. The AM‐OLED display was 0.7mm thick and weighed only 3.2g. A clear image was successfully obtained on the all‐plastic substrate color AM‐OLED display, indicating the tremendous potential of SUFTLA technology in the manufacture of thin, lightweight, flexible electronic devices.
