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...
We present experimental results using an alternative cross-linker for poly(4-vinylphenol) (PVP) that allows lowering of the thermal budget of the cross-linking reaction to 130°C which compares very favorable to the 180°C required by the commonly used cross-linking agent poly(melamine-co-formaldehyde). Furthermore, we characterize the dielectric properties of a 200nm thick layer and realize high quality...
