Titel
Design and realization of a flexible QQVGA AMOLED display with organic TFTs
Abstract
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 0.4cm 2/Vs. The aperture ratio of the top-emitting OLEDs is over 75%. For operation at 10V supply voltage (V DD), the brightness of the display using red and green OLEDs exceeds 200cd/m 2.
