Abstract
A light emitting diode package structure is provided. The light emitting diode package structure includes first and second chips. A value of an intensity of a peak wavelength of a first shoulder wave of the first chip divided by an intensity of a peak wavelength of a first main wave of the first chip is defined as a first intensity ratio. A value of an intensity of a peak wavelength of a second shoulder wave of the second chip divided by an intensity of a peak wavelength of a second main wave of the second chip is defined as a second intensity ratio. The first and second chips satisfy 'a difference between the intensities of the peak wavelengths of the first and second main waves being less than or equal to 2.5 nanometers' and 'a difference between the first and second intensity ratios being greater than 0.1'.
