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.

Abstract: A light source device includes a LED light source or a wavelength conversion material having a near Lambertian light emitting surface. The light source device includes a light recycling system to reflect small-angle lights (lights closer to the normal direction of the light emitting surface) back to the light source, and a collection system for collecting and outputting large-angle lights (lights farther away from the normal direction). The lights reflected by the light recycling system is scattered by the emitting surface in all directions, where the large-angle scattered lights are collected by the light collection system and the small-angle scattered light is reflected by the light recycling system again. A second excitation light source without wavelength conversion material or a second light source with its own wavelength conversion material may be provided, and the second light is directed to the light emitting surface by appropriate optical components.

Abstract: A projection screen includes an optical collimating layer and a surface diffusion layer which are arranged in sequence. A grating absorption layer for absorbing ambient light from various directions except a projection light direction is also provided between the optical collimating layer and the surface diffusion layer. The grating absorption layer includes a plurality of light-absorption ring-shaped units with different radii. The plurality of light-absorption ring-shaped units are arranged in a concentric ring. Each of the light-absorption ring-shaped units consists of a plurality of gratings arranged in the circumferential direction of the concentric ring. By taking a vertical symmetrical center line of the projection screen as a center, in a direction extending along the circumferential direction of the concentric ring to the left side and the right side of the projection screen, the distance between two adjacent gratings in the same light-absorption ring-shaped unit gradually increases.
