摘要：
A light-emitting diode (LED) backlight module comprises a light guide plate, an LED element and fluorescent powder; wherein, a reflecting surface and a light extraction surface of the light guide plate are arranged in a nonparallel manner; the fluorescent powder is spread on the surface of the light guide plate, in the body of the light guide plate or on the encapsulation shell of the LED element; partial excitation light emitted by the LED element is excited into transmitting light with different wavelength by the fluorescent powder, and the transmitting light is mixed with the excitation light to generate the light in other colors.
