Among these technologies, the color reproducibliity of White, Red, Green, and Blue is associated with the TV plaform and is expressed as a major technology. Major TV platforms are divided into three categories since 2015, including LCD-based phosphor coverted LED BLU technology, QD sheet technology using nano-sized quantum dots, and OLED technology. In this paper, we describe the color reproducibility definition and background, luminescent materials with wide color gamut, color reproducibility of TV display performance, and discuss about next luminescent materials.
