Abstract
The projection optical path comprises a triple light source system emitting a first converged light and a single light source system emitting a light with a monochromatic wavelength. The triple light source system comprises a second converged light converged with a light with a first wavelength to form the first converged light. The single light source system comprises a third light source. The light with the first wavelength, the light with the second wavelength, and the light with the third wavelength are respectively one of red light, green light, blue light, a wavelength range of a light with a fourth wavelength is within a wavelength range of the red light. The wavelength of the light with the fourth wavelength is defined as λ1; the wavelength of the red light among the lights with the three wavelengths is λ2, and λ1≠λ2.
