Abstract: The light source system includes a first light source, a light splitting device, a wavelength conversion device, and a light guiding device. The first light source emits first light. The wavelength conversion device includes at least a first color light region and a second color light region, which are sequentially inserted into an outgoing path of the first light. The first color light region emits second light excited by the first light to the light splitting device. The second color light region reflects the first light to the light splitting device. The light splitting device directs one of the first light and the second light to a light path and directs the other to the light guiding device. The first light or the second light is reflected by the light guiding device to the light splitting device, and then is guided to the light path by the light splitting device.

Abstract: A display system includes: a light source, a light modulator, a recovery device, and a light intensity adjustment device. The light source emits original light that is incident to the light modulator. The light modulator modulates, on the basis of image data of an image to be displayed, the light incident thereto so as to form image light and non-image light. The recovery device recovers the non-image light, and the recovered non-image light is incident to the light modulator. The light intensity adjustment device adjusts, on the basis of the intensity of the non-image light corresponding to the currently modulated image to be displayed, the intensity of the original light emitted by the light source, thus allowing total intensity of the original light and the recovered non-image light that are incident to the light modulator to be kept consistent in modulation periods for different images to be displayed.

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.
