Zusammenfassung:This paper reports a low‐temperature polycrystalline silicon (LTPS) fabrication process on plastic substrate for a flexible AMOLED display. Characteristics of fabricated TFTs showed excellent performance with field effect mobility of 124.1 cm2/V‐s, on/off ratio of >108, subthreshold slope of 0.30V/dec, and threshold voltage of −2.03V. Internal scan drive circuits, 1:3 demux, and compensation circuits were successfully integrated on the backplane of a 166ppi 2.8″ WQVGA flexible AMOLED panel.
