The present invention discloses a control TFT structure (i.e. a driving TFT) for reducing leakage in an OLED display. A semiconductor layer, such as a polysilicon layer, is deposited on a transparent substrate as a channel region. A lightly doped region and a drain region are disposed on one side of...http://www.google.fr/patents/US7202096?utm_source=gb-gplus-shareBrevet US7202096 - Control TFT for OLED display
