The invention discloses an implementation method for a high-color-gamut white LED (Light Emitting Diode) using MxSr1-xTiO3:Eu2+,Mn2+ blue phosphor. The implementation method comprises the following steps of (1) weighing blue phosphor, green phosphor and red proportionally and adding into hybrid packaging glue; (2) dropping a mixture obtained in the step (1) into an LED support cup shell provided with the ultraviolet chip; and (3) solidifying the packaging glue to obtain a white LED lamp bead. According to the method, the adopted red phosphor is MxSr1-xTiO3:Eu2+,Mn2+ blue phosphor with high excitation efficiency, so that a color gamut value of the LED backlight lamp bead can be remarkably increased to be more than 85%, and the high-color-gamut white LED is used for liquid crystal backlight, so that the color reduction degree of a display screen can be greatly improved.
