High performance TFTs with a short channel and good uniformity are required to mass-produce transparent top emission OLED TV. The uniformity of Vth and Ion are improved by controlling effective channel length. Negative Vth shift under NBTiS conditions is improved by optimizing light shield and buffer layers.
