- the present color gamut domain is represented by a wide band width due to the wavelength of the fluorescing fluorescent powder, and the green and green light color sitting BB mark is close to the center of the center, and the color gamut is triangular.
- the surface area is small, and the cocoa table shows the current color and color. .
- the green-green light-color color coordinate coordinate DD When the addition of the green-green light-excited laser light into the component, the green-green light-color color coordinate coordinate coordinate DD is far away from the center-centered center, and the AGDCC surface 1155 in the color-gamut domain has a larger accumulation.

It is possible to produce the bluish light and the red light by using the above-described method, that is, the blue light, the red light, the laser light, and the fluorescent light. The phases are combined to form. . Because it is different for the degree of the effect of the light and light on the three triangular shapes of the color gamut and the effect of the scattered plaque, it is combined into the green and green light by the above-mentioned method.

- the above-described method of synthesizing into laser light and fluorescent light provides a means for hand-optimizing the color saturation and degree of the color source of the light source. .
- the situation is the case of the full laser light, which can be seen from the figure. It can be seen that although the laser color light can be used to obtain the largest and largest color gamut, it is in this situation. Similarly, there will be situations in which the existing scattered streaks are more severe and severe. . That is, if the pure pure laser light is used as the light source, the green and green color coordinates will be in the boundary of the entire color gamut, and the color gamut is three. The area of the triangular-shaped surface will be larger and larger, but the source of the purely pure laser light source will bring the severely intense laser light phase to thousands of scattered spots, and the shadow effect will be affected. The image is like a picture quality. .
- I ( ) is the spectral distribution of the source. Is the standard stimulus curve. In the xy color space, the color coordinates are:
- the area of the color gamut triangle can be calculated.
- speckle the intensity of the reflected or projected light of the screen is uneven (ie, speckle), and the intensity of the picture is (p is the intensity).
- the probability of I) the definition of speckle contrast is:
- Figure 3b is a calculation result of the example of Figure 3a.
- the blue light is laser LD

- Figure 3b shows the corresponding color gamut change and speckle contrast change as the green laser fluorescence ratio changes.
- curve A represents the speckle contrast.
- Curve B is the relative area of the gamut triangle (ie, the ratio of the gamut triangle area to the gamut triangle area of pure green fluorescence). We can see that as the fluorescence component increases, the gamut becomes smaller. About 60% of the fluorescent component is most effective for the purpose of reducing speckle contrast and increasing color gamut design.
- the speckle contrast was reduced from 100% of the pure laser source to 27%, and the xy space gamut area was increased by 32% compared with the pure fluorescent source. It should be pointed out that for the sake of simplicity of calculation, the gamut area is performed in the xy gamut space. Since the non-uniformity of the xy space will underestimate the gamut increase, the actual gamut surface increase will be higher. The color gamut of the fluorescent light source is too small and the color saturation is low. It is only suitable for some commercial projection applications. With the combination of laser and fluorescence, the increased color gamut can meet the needs of entertainment applications such as home theater. In addition, the speckle contrast should be as small as 5% to the human eye.
