The invention relates to a system and method of dynamically adjusting the color gamut of a display system and the display system. The display system comprises a light source system and an imaging system. The light source system comprises an exciting light source and a narrow-spectrum primary color light source. The exciting light source emits exciting light, the exciting light is processed to output at least one kind of wide-spectrum primary color light, the narrow-spectrum primary color light source outputs at least one kind of narrow-spectrum primary color light, the narrow-spectrum primarycolor light and the wide-spectrum primary color light are combined and then output to the imaging system. The method comprises the following steps of: calculating the color coordinates and the brightness of the brightest pixel point of a frame image, calculating the minimum brightness value of the wide-spectrum primary color light according to the color coordinates and the brightness of the primary color light and the brightest pixel point of the light source system, calculating the brightness value of the narrow-spectrum primary color light, and generating and outputting light source brightness signals of the exciting light source and the narrow-spectrum primary color light source according to the brightness values so as to adjust the brightness of light emitted by the exciting light source and the narrow-spectrum primary color light source. The color gamut is enhanced, the efficiency is improved, and the cost is reduced.
Description
technical field [0001] The invention relates to a display system, in particular to a projection system, a method and a display system for dynamically adjusting the color gamut of the display system. Background technique [0002] In a basic laser fluorescent light source, the short-wavelength visible light emitted by the laser excites the phosphor on the wavelength conversion device to generate sequential fluorescent primary color light or white light. However, due to the wide spectrum of fluorescent light, the color gamut of this light source covers a relatively large area. narrow. In another improved laser fluorescence light source, the short-wavelength visible light emitted by the laser is converted into primary color light by a wavelength conversion device and filtered by a synchronous filter device to obtain a narrow-band primary color light with higher color purity to expand the color gamut of laser fluorescence. In this scheme, the optical filter will cause additional...
