  • Patent number: 9484505
    Abstract: An LED structure is applied to a backlight source to set a white light of a backlight module at a standard D65 position of the CIE1931 chromaticity coordinates and used together with a display module. A red phosphor for emitting a red light, a yellow phosphor for emitting a yellow light, and a blue light LED chip are provided. The mixing ratio of the red phosphor to the yellow phosphor is controlled within a range of (2.33?1):1, so that the original LED white light falls within a region enclosed by ccy?1.8*ccx?0.12, ccy?1.8*ccx?0.336, ccy?0.33 and ccy?0.15 of the CIE1931 coordinates. Since the red phosphor does not absorb or convert yellow light, the brightness loss of the yellow light that excites the yellow phosphor is minimized. A color filter may be installed to achieve better NTSC effect and luminous efficacy.
