70.1: High‐Resolution OLED Display with the World's Lowest Level of Power Consumption Using Blue/Yellow Tandem Structure and RGBY Subpixels

A top-emission organic light-emitting diode (OLED) with a a microcavity structure combined with a blue/yellow tandem structure was developed. A high-resolution active-matrix OLED display with the world's lowest level of power consumption using the tandem OLED with red, green, blue, and yellow subpixels was fabricated.
