We present a QQVGA top emitting monochrome AMOLED display with 85dpi resolution using an organic TFT backplane on low temperature PEN-foil. The backplane process flow is based on a 7 layer photolithography process that yields a final mobility of the OTFT of similar to 0.4 cm(2)/Vs. The aperture ratio of the top-emitting OLEDs is over 75%. For operation at 10 V supply voltage (V-DD), the brightness of the display using red and green OLEDs exceeds 200 cd/m(2).
