Projector system

A projector system comprising:

• a light source module comprising a red-color light source for emitting red light, a green-color light source for emitting green light and a blue-color light source for emitting blue light;
• a light guiding plate configured for optically combining the red light, the green light, and the blue light, the light guiding plate comprising a light input surface, a light output surface and a light reflecting surface, the red-color light source, the green-color light source and the blue-color light source facing toward the light input surface;
• a polarizing beam splitter (PBS) module configured for splitting the combined red light, green light and blue light into s-polarization light and p-polarization light, reflecting the s-polarization light and converting the reflected s-polarization light into p-polarization light, modulating and outputting the converted p-polarization light using a display information signal, the PBS module being opposite to the light output surface of the light guiding plate;
• and
• a projection lens module configured for projecting the modulated p-polarization light onto a screen panel.
