Abstract 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.
