Abstract: A system and method for dynamically adjusting a color gamut of a display system, and a display system are provided. The display system includes a light source system and an imaging system. The light source system includes an excitation light source and a narrow-spectrum primary-light source. The imaging system includes a spatial light modulation device and the system for dynamically adjusting the color gamut of the display system. The excitation light source emits excitation light which is processed to output at least one broad-spectrum primary light. The narrow-spectrum primary light source outputs at least one narrow-spectrum primary light. The narrow-spectrum primary light and the wide-spectrum primary light are combined and then output to the imaging system. The brightness of light emitted by the excitation light source and the narrow-spectrum primary light source is adjusted. Therefore, the efficiency is improved and the costs are reduced while enhancing the color gamut.
