A new driving method introducing a display period for AMOLEDs

— We have proposed an Advanced-Clamped-Inverter driving method for the fabrication of AMOLEDs, in which one frame period is divided into an addressing period and a display period. This driving method enables the AMOLEDs to produce excellent moving images without motion blur and false pixels, and has peak-luminance characteristics because of its unique light-emission scheme of the OLED elements. Good inter-pixel uniformity was also achieved in a previous clamped-inverter driving method. We fabricated AMOLEDs and experimentally confirmed their characteristics.
