摘要
Liquid crystal displays (LCDs) play a dominant role at the present stage among various display approaches due to the modern technology, durability, reasonable cost. The performance of LCD devices would be significantly influenced by its backlighting system, which is based on inorganic solid-state phosphor-converted light-emitting diodes (pc-LEDs). To achieve a wide color gamut display, the phosphors for backlighting should possess high color purity, which is determined mainly by the peak position and full-width at the half-maximum (FWHM) of the emission band. In this review, a detailed overview of the narrow band-emitting phosphors based on Eu2+, Mn2+, and Mn4+ activators for LCD backlighting application are introduced, including some commercial phosphor systems, well-known phosphors, and other potential candidates. This review focuses on the progress of the inorganic solid-state phosphors for LCD backlighting application from the viewpoint of structure and performance. It would also provide possible clues for the further development of LCD-used phosphors in fundamental and practical aspects.
