Flexible QQVGA AMOLED display with organic TFTs
conference paper
We present a QQVGA top emitting monochrome AMOLED display with 85dpi resolution using an organic TFT backplane on low temperature PEN-foil. The back plane process flow is based on a 7 layer photolithography process that yields a final mobility of the OTFT of ∼0.4cm2/Vs. The aperture ratio of the top-emitting OLEDs is over 75%. For operation at 10 V supply voltage (VDD), the brightness of the display using red, green or blue OLEDs exceeds 200cd/m2. We will furthermore discuss the relevant parameters that determine the performance of our organic backplanes for OLED displays, in particular bias stress, output resistance, uniformity and current drive capability.
