Five-color laser color gamut extended display device and method for displaying colors

Abstract

The invention discloses a five-color laser color gamut expanded display device and a color display method of the five-color laser color gamut expanded display device, and relates to a device for controlling the intensity, colors, phases and polarization or directions of light from independent light sources. The five-color laser color gamut expanded display device comprises a semiconductor laser device adjustable power supply a, a semiconductor laser device adjustable power supply b, a semiconductor laser device adjustable power supply c, a semiconductor laser device adjustable power supply d, a semiconductor laser device adjustable power supply e, a green-yellow light semiconductor laser device, a red light semiconductor laser device, a green light semiconductor laser device, a blue-violet light semiconductor laser device, a blue-green light semiconductor laser device, a lens a, a lens b, a lens c, a lens d, a lens e, a lens f, a reflecting mirror a, a reflecting mirror b, a beam combiner a, a beam combiner b, a beam combiner c and a display screen. According to the five-color laser color gamut expanded display device, the five non-equidistance center wavelength semiconductor laser devices output five colors of lasers to expand color display in 1931CIE-XYZ chromaticity diagrams, and the defects that in the prior art, the area of displayed colors for covering a tongue-shaped region of the 1931CIE-XYZ chromaticity diagrams is small, the color development range capable of being sensed by human eyes can not be displayed to the maximum degree, and the goal of achieving color display similar to the range of the1931CIE-XYZ chromaticity diagrams through a small number of display devices is not achieved are overcome.

Description

technical field [0001] The technical solution of the present invention relates to a device for controlling the intensity, color, phase, polarization or direction of light from an independent light source, specifically a five-color laser color gamut expansion display device and a method for displaying colors thereof. Background technique [0002] In 1931, the International Commission on Illumination (CIE) clearly stipulated the stimulus value of the three colors of red, blue and green for the human eye. Color TVs and LCD monitors and other equipment use the combination of red, blue and green primary colors to display color patterns in images and videos. Although red The three primary colors of blue and green can display various colors such as red, orange, yellow, blue, green, and white. In practice, the chromaticity coverage of the three primary colors is limited due to the light-emitting diode (LED) emission spectrum in color TV phosphors and liquid crystal displays. In the ...

Problems solved by technology

The prior art in this technical field begins to pay attention to the display method of improving the color area coverage of the 1931CIE-XYZ chromaticity diagram. CN101720045B discloses a method for converting hue and brightness in laser display color gamut expansion. The image presented by the three-primary-color laser is more layered and close True colors in nature, but because only red, blue and green lasers are used, there are still more colors that cannot be displayed near the green and blue areas in the 1931CIE-XYZ chromaticity diagram

CN101002135A announced a multi-primary color display device, a liquid crystal display device that uses multi-primary color image display to expand the color display range, and CN101006484A announced a multi-primary color display device and a liquid crystal display device, a display device that uses integer primary colors greater than or equal to 4 to form an image, but It does not explain the chromaticity coordinates of each primary color and the area covered by the 1931CIE-XYZ chromaticity diagram

To sum up, the above-mentioned disclosed prior art has the following problems: the area of ​​the tongue-shaped area of ​​the display color covering the 1931CIE-XYZ chromaticity diagram is too low, and the color rendering range that the human eye can perceive is not displayed to the greatest extent, and it has not reached the level of a small number of uses. The display device realizes the color display close to the range of the entire 1931CIE-XYZ chromaticity diagram
