説明

<jats:title>Abstract</jats:title> <jats:p>We report a 55‐inch OLED TV employing white organic light emitting device (WOLED) and oxide TFT. We fabricated the hybrid tandem structure comprising a phosphorescent R/G stack and a fluorescent blue stack to achieve high current efficiency of 90cd/A at 1,000 nit and white color (0.327, 0.344). 55‐inch OLED TV was adjusted to cool white color of (0.285, 0.294). We applied a color layer for large color gamut (118% ATSC ratio) and deep blue expression (0.142, 0.054). We also improved 3 kinds of color shift over viewing angle, aging and gray level.</jats:p>
