— In this paper, the performance of active‐matrix‐driven small‐molecule OLED displays incorporating high‐efficiency electrophosphorescent dopants were analyzed. These enable triplet excitons to contribute to light emission and have led to pixel efficiencies of over 40 lm/W. By considering a conventional two TFT per pixel addressing scheme, we show how this OLED design enables the fabrication of very‐low‐power‐consumption displays (lower than AMLCDs). We simulate display performance and perform a trade‐off analysis comparing the power consumption of displays driven by both amorphous‐silicon and low‐temperature poly‐Si TFTs.
