Abstract

Abstract : We present a QVGA (320x240 with 3 sub‐pixel) top‐emitting AMOLED display with 250ppi resolution using a self‐aligned (SA) IGZO TFT backplane on polyimide‐foil with full barrier. The back plane process flow is based on a 7 layer photolithography process. The aperture ratio of the top‐emitting OLEDs is approx. 80%. An integrated gate driver is shown that can be driven at operation speed equivalent to a 4k2k display at 100Hz.
