Why is the three-color laser light source the future?
2022-12-07
After talking about the LED light source, let's talk about the laser light source. The brightness of the laser light source is higher, and the picture quality effect will be better controlled. The laser light source can directly select the red, green and blue three-color laser generators of specific bands according to the needs. The three-color laser light source can reach 100% BT.2020 color gamut coverage, which exceeds the color gamut of OLED TV and QLED TV. limit of coverage. Therefore, the imagination space of the three-color laser light source is very large, and the range that can undertake future viewing needs is also wider. The light sources of laser projectors are divided into several categories. Among them, monochromatic lasers use a single blue laser to excite yellow and green phosphors on the fluorescent color wheel, and then separate red, green, and blue light through a prism, and finally combine to form other colors. , and then pass through a filter to refine the color. The monochromatic laser light source itself does not have red light and green light, so there will be color loss. If you want brightness, you lose color; if you want color, you lose brightness. This is why many people do not recommend single-color or two-color light sources. 
In contrast, the three-color laser light source does not have the problem of brightness and color, so many players used in high-end theaters use three-color laser light source. However, the three-color laser light source also has the problem of speckle, which is generally eliminated by vibrating screens in movie theaters. Household level is eliminated by reducing power. Through the above content, we can see that the three-color laser light source will be a "future", but the problems of speckle and high price are also problems we have to face. If any brand can solve these two problems, then the projector with three-color laser light source will definitely become the new mainstream.
