Abstract

Abstract A low temperature, 180 °C, amorphous Si (a‐Si:H) process on bonded polyethylene naphthalate substrates is discussed and a 4.1‐inch QVGA active matrix (AM) phosphorescent OLED display is demonstrated. The n‐channel thin‐film transistors (TFTs) exhibited saturation mobilities of 0.773 cm 2 /V‐sec, layer to layer registration distortion less than 10ppm and low defectivity. The efficiency of the OLED display is 39 cd/A at 500 nits.
