Abstract
A structure of light emitting diode (LED) effectively reduces its spectral width. The LED structure is applied in a three color mixing of a backlight module to broaden a color space and to improve a saturation of a color display. A grating structure is used as a waveguide layer to coordinate with the LED structure. The present invention does not affect the original thermo and electrical characteristics of the LED structure and has a simple fabrication method.
