Abstract
A light source module including a plurality of first point light sources, a plurality of second point light sources, and a plurality of third point light sources is provided. The dominant wavelengths of lights provided by the first point light sources are within a wavelength range of a first color light, and at least two of the first point light sources emit light with different dominant wavelengths. The dominant wavelengths of lights provided by the second point light sources are within a wavelength range of a second color light, and at least two of the second point light sources emit light with different dominant wavelengths. The dominant wavelengths of lights provided by the third point light sources are within a wavelength range of a third color light, and at least two of the third point light sources emit light with different dominant wavelengths.
