Abstract
Disclosed are a light source and a display system. The light source comprises at least one original light emitting device group () and at least one supplementary light emitting device group (). The original light emitting device group () comprises at least two LED () and a wavelength light combining device (), wherein the energy of the overlapped spectrum in the normalized spectrum of the two LED is smaller than 50% of the smaller energy of the two, and the wavelength light combining device combines the light output from all the LED in the original light emitting device group () in a wavelength light combining way. The supplementary light emitting device group () comprises at least one LED (). The energy of the overlapped spectrum in the normalized spectrum of any LED of the supplementary light emitting device group () and at least one LED of the original light emitting device group () is larger than or equal to 10% of the smaller energy of the two. The light source also comprises a geometric light combining device (), which combines the light finally output from the original light emitting device group () and the light finally output from the supplementary light emitting device group () into one beam of light in a geometric light combining way.
