AB - Color‐by‐blue quantum dot (QD)‐emissive liquid‐crystal displays (LCDs) with eco‐friendly, green, red (GR) InP/ZnSeS/ZnS QD films are introduced to overcome the disadvantages of conventional color‐by‐white color filter (CF)‐assisted LCDs, such as a narrow viewing angle, low external device efficiency of these types of LCDs, and a restricted color gamut. In this study, the color‐by‐blue InP‐based QD‐emissive LCD consists of a blue (B) light‐emitting diode (LED) and GR InP‐based QD films sandwiched between a light recycling filter and a long‐wavelength pass dichroic filter. The GR InP‐based QDs are synthesized with a high photoluminescence quantum yield (>77%) and narrow bandwidth (<40 nm), which are suitable for display applications. The overall enhancement of InP‐based QD‐emissive LCDs, in this case by the enhanced efficiency of a blue LED backlight transmitted through the LC shutter compared to a white LED backlight and the improved efficiency of the enlarged color gamut, is 2.42 times that of a conventional red, green, and blue (RGB) CF‐LCD with a GR phosphor‐converted (pc)‐LED (a B LED + R K2SiF6:Mn + G β‐SiAlON:Eu phosphor) backlight. Therefore, this considerable enhancement of the external efficiency of a QD‐emissive LCD makes it more feasible as a replacement for conventional RGB CF‐assisted LCDs.
