In the modern world, the white light-emitting diodes (LEDs) play an important and basic role on various fields, including illumination and display back board. To obtain excellent performance white LEDs, the emissive materials needed to be studied. As a kind of promising semiconductor, inorganic perovskites (CsPbX₃, X=Cl, Br, I) exhibit prominent potentials in the white LEDs, due to their high photoluminescence quantum yields, tunable emission wavelength, high color purity and excellent stability. In this review, the research progresses in the electroluminescent and photoluminescent white LEDs based on inorganic perovskites were introduced. Then, the represent achievements on the white LEDs of the mix of improved inorganic perovskites and other emissive materials, as well as the single components of inorganic perovskites, could be exhibited. In the end, the employment of the white LEDs on visible light communication was highlighted. In addition, the development trends of the white LEDs and visible light communication were summarized and prospected.
