43.3: Power Efficient AMOLED Display with Novel Four Sub-Pixel Architecture and Driving Scheme

We present a novel all-phosphorescent AMOLED pixel architecture with a red, green, light blue and deep blue sub-pixel design. The highly efficient light blue reduces power consumption by 33% compared to an equivalent conventional RGB display using a fluorescent blue sub-pixel. Furthermore, by using a light and deep blue sub-pixel layout, the lifetime of the display will be significantly increased due to the reduced on-time required for the deep blue sub-pixel. Here we demonstrate this new design in a 2.5-inch AMOLED panel.

42.1 Invited Paper: High Efficiency Phosphorescent AMOLEDs: The Path to Long Lifetime TVs

In this paper we present results of blue PHOLED technologies, and outline different AMOLED display architectures, comparing their performance and power consumption. Projected operating temperatures of AMOLED TVs are correlated to device lifetimes to show the lifetime enhancements enabled by the power savings of phosphorescent OLEDs. These results allow us to analyze compelling technology packages for OLED TVs.
