In this paper, the FWHM and quantum efficiency of organic light‐emitting materials are analyzed, and the feasibility analysis of organic light‐emitting materials adopted in LCD module for the widest color gamut are researched and developed. By matching the color filter design, Adobe RGB coverage 99.5% and DCI‐P3 coverage 99.5% is achieved. And by adjusting the red material emitting wavelength, bt2020 coverage 91% is achieved. In terms of environmental protection and non‐toxic, organic light‐emitting materials without heavy metal components are significantly more environmental friendly than CdSe QD. In terms of energy efficiency, the LCM with organic light‐emitting film has better performance than that with InP QD film.
