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

Abstract

A top-emission organic light-emitting diode (OLED) with 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.

Improvement of Colour Gamut in Bottom-Emission Organic Light-Emitting Diodes Using Micro-Cavity Structure Embedded Cathodes

“…Organic light-emitting diodes (OLEDs) have received particular attention as a future display device for their many advantages such as their thinness, light weight, flexibility, high contrast ratio, and low power consumption [1][2][3]. Full-colour active-matrix (AM) OLED panels have already been utilized in large-sized TVs as well as cellular phones.…”

20‐3: Novel Host‐Guest System for Drastic Improvement in the Lifetime of a Deep‐Red OLED that Satisfies the Red Chromaticity of the BT.2020 Standard

“…We found a c-axis aligned crystalline In-Ga-Zn oxide (CAAC-IGZO) and a nanocrystal IGZO (nc-IGZO) [2,3,4], which have different crystal morphologies from a singlecrystal IGZO and an amorphous IGZO. We developed AMOLED displays whose backplanes contain such IGZOs [5,6]. OLED displays essentially have high contrasts, and thus provide the strong sense of immersion and realism [7].…”
