In recent years, the technology of the home projector industry has been gradually upgraded, from the early traditional bulb machine to the rise of intelligent micro-projection dominated by LED light source, and then to the popularity of laser projectors now, every innovation in home projector light source technology has brought users a higher level of audio-visual experience.
Conventional light bulb machinesIt is an old-fashioned projector, with mature technology, good brightness and color performance, and is commonly used for teaching and office purposes. However, after running for a long time, the life of the bulb consumes very quickly, and it will also bring the problem of high noise, which is not suitable for home scenes.
LED projectorIt is a projector that uses LED light source, and the product is positioned in the middle and low end. Due to the advantages of small size, long life and low cost, LED light source has become one of the commonly used light sources for projection manufacturers. The color contrast and saturation of its picture are relatively balanced,But there is an upper limit to brightness,High-end LED projectors can only reach3000ANSI lumens,It can no longer meet the user's needs for high image quality。
At this stage, the home projection market is gaining momentumLaser projector, the product positioning is in the high-end, known as the peak and future of home projectors. There is no other reason, because the laser light source it uses has perfect technology, with the advantages of high brightness, wide color gamut, high contrast, high light efficiency and long life, which comprehensively crushes other light source technologies.
Previously, the laser light source was commonly used in high-end laser theaters or tens of thousands of yuan of laser TVs,Due to the high cost,Projection manufacturers have no choice but to develop transition technology,That isMonochromatic lasers and mixed-color lasersto further promote the popularity of home laser projectors. With the development of laser technology and industry, three-color laser technology has gradually stepped onto the stage of the times and has become the most advanced and mature laser display technology.
[The difference between laser light sources].
1. Monochrome laser
Monochrome laser is a single blue laser shining on the fluorescent color wheel to excite red and green light, and then synthesize and output different colors of the picture effect. Compared to LED light sources, monochromatic lasers are brighter. Since only one laser is added, the effect of real laser brightness cannot be exerted, and the light emitted by the fluorescent color wheel destroys the purity of the light, and the accuracy of the synthetic color decreases, resulting in the problem of color cast in the picture. And the monochrome laser contains high-energy short-wave blue light, which will have the hidden danger of blue light hurting the eyes, so be cautious if you have children.
2. Color mixing laser
The mixed color laser is to add LED panchromatic light on the basis of monochromatic laser, improve the defect of insufficient brightness of LED light source with laser, and then use LED light source to make up for the problem of monochromatic laser color bias. However, in actual use, LED has become a technical shortcoming. The LED light source must improve the efficiency to cooperate with the laser to make up for the missing color, and the long-term high-intensity operation will cause heating and light decay, which will affect the picture effect and service life. At the same time, the purity and collimation of the LED light source are not strong, but it destroys the advantages of the laser, and the technology as a whole is dominated by the LED light source, and the color performance and contrast are all LED projector ranges.
3. Three-color laser
The three-color laser uses three suitable wavelengths of lasers to emit red, green and blue colors, and synthesizes the required different colors and patterns directly on the screen without passing through the phosphor wheel. The resulting light is of high purity, accurate in synthesized colors, and up to 110% bt. in color gamutIn 2020, it is nearly 2 times that of the LED light source, the brightness can easily exceed 3000ANSI lumens, and the picture uniformity is as high as 95%, far exceeding the industry average, and the four corners of the picture will not be gray and dark. Used in the projector, it can output high-definition lossless, delicate and saturated picture effects, comparable to the visual effects of laser theaters.
In the past, due to the small scale of red laser production and the complex technology of laser luminous efficiency allocation, the product cost was too high. In recent years, as projection manufacturers have invested heavily in research and development, they have finally realized the inclusiveness of three-color laser technology. For example, the leader of the home intelligent projection industry-nuts, which took three years of independent research and developmentMalc meshkrypton three-color laser light machineIt realizes the perfect combination of home projector and three-color laser technology, and further improves the picture quality and color uniformity of home projector, and improves the visual image quality.
Nut also used the optical machine in the entry-level projection model of 3,000 yuan, so that the top technology into thousands of households, so that more users can enjoy the visual shock brought by the three-color laser technology. In response to the speckle theory spread by individual netizens, an excellent solution has been come up. Nut pioneered LSR dynamic spot dissipation technology, to achieve more than 97% of the picture speckle removal, to meet the requirements of the National Standards Committee of "less than 3% speckle rate", to achieve the effect of no human eye to perceive speckle, the picture texture is delicate, and the presence of speckle can not be seen at close range.
To sum up, judging from the picture effect,Three-color laser technology is the best. Therefore, when choosing a home projector,Three-color laser projectors are preferred for products at the same price.
Here is a list for everyoneA recommended list of home laser projectors in the 6000 price segment. This price point is the pricing of the flagship projection models of major brands, which combines representative technologies, ultra-high-definition resolution and innovative features, etc., with extremely high cost performance, which can bring a high-level viewing experience.

vidda c1s
Vidda also has a variety of three-color laser products. The Vidda C1S is an upgrade of the original three-color laser product, the C1. The color gamut has been increased from 107% BT2020 to 110% BT2020, the contrast ratio has increased from 1000:1 to 1600:1, and the brightness has also increased from 1350 CVIA lumens to 1600 CVIA lumens, the performance has been significantly improved, and the projection image quality has been further improved, but the brightness is a bit inferior, and it is not advantageous in products at the same price. At the same time, some users also reported that speckle is more obvious, which affects the picture effect.
Built-in flagship-level chip MT9669, with 4+64GB large memory, to ensure **4K ultra-high-definition movies, or play games, watch sports events can be smooth and non-stuck. The appearance is too tough and square, and it looks bulky. It is officially recommended to use hoisting or external gimbal brackets, which are more troublesome and far less convenient than the integrated one.
XGIMI H6 Pro
XGIMI H6 ProBrightness up to1920CCB,Equivalent to2400CVIA lumens,Brightness performance is good。 rec.709 color gamut coverage accounts for 999%, DCI-P3 color gamut coverage accounts for 95%, and the color performance of the picture is close to that of LED projectors, which is relatively balanced. It also supports 4K resolution and Dolby Vision for a detailed and vivid picture.
However, it adopts dual light super light mixing technology, that is, the color mixing technology of monochrome laser + LED full color light. This is a major attempt by XGIMI to break the technical bottleneck of a single light source. It is a pity that the LED light source destroys the purity of the laser, resulting in the color expression ability can not reach the effect of three-color laser products at the same price, and also brings problems such as running heat and aging of lamp beads.
