75‐3: Ultrawide color gamut LCD display with CdSe/CdS nanoplatelets

We present an LCD backlight made of nanoplatelets (NPLs) for the first time. Owing to the narrow emission linewidth of NPLs (8~12 nm) and QDs, the spectrum exhibits a wide color gamut display with a 139.9% color gamut of NTSC (National Television System Committee) 1953 standard and 104.5% Rec.2020 (ITU‐R Recommendation BT.2020), realizing a truly ultrawide color gamut LCD display.
