With the rapid development of science and technology, laser technology is gradually becoming the mainstream technology in the projection market, and major projection manufacturers have entered this field. Among the many laser technologies, the three-color laser light source, which is known for its excellent picture performance and wide application prospects, has become the focus of the laser field.
However, for ordinary consumers who are considering purchasing a projector, which of the two technologies in laser technology, monochrome laser or tricolor laser, is superior?At the same time, what are the advantages of three-color laser?Next, we will detail these questions to provide you with reference and understanding, so that you can choose a projector that is more suitable for your needs.
The principle and advantages and disadvantages of monochromatic laser
Monochromatic lasers are high-intensity monochromatic beams produced by lasers. Also known as ALPD 10 technology was developed by Guangfeng Technology in 2007. It uses a single blue laser light source that is irradiated on a rotating fluorescent color wheel to produce panchromatic light, which is then projected onto a DMD chip through a prism to form a projected image.
Because monochromatic lasers only use a single blue light, there is a natural lack of red and green lasers, so it is easy to be disturbed by the stray light emitted by the rotating fluorescent color wheel when synthesizing colors, resulting in impure colors, color casts, and the picture is more prone to distortion. In order to maintain the accuracy of the color of the picture, it is necessary to increase the filtering of the prism, which will cause the brightness of the light to be greatly reduced, and the highlight advantage of the laser cannot be brought into play.
In the early days, due to the high cost of three-color lasers, manufacturers adopted monochrome laser technology in order to save R&D and manufacturing costs, and at the same time, they could use "laser" as a selling point to trigger a sales tide, which can be said to have drilled the blind spot of the public. Up to now, the public has become more familiar with home projectors,Monochrome laser, as a relatively old "laser" technology, is more used in low-end projector products。
2. The principle and advantages and disadvantages of three-color laser
The three-color laser is a laser that produces red, green and blue colors through the laser, and forms various graphics and colors directly on the screen through the combination of corresponding optical components. In other words, the light it emits is not polluted by other light sources, it is purer, and it can present a very rich color effect.
As an advanced technology in projection equipment, three-color laser technology has more obvious advantages than monochromatic laser in all aspects.
High brightness and high contrast:Due to the higher luminous efficiency of the laser, and the trichromatic laser has no interference from other light sources, the spectrum is pure and unmixed, and the projected light has almost no stray light. This feature greatly increases the brightness of the projection, so that the picture can still be clearly seen in bright environments. At the same time, its light divergence angle is very narrow, only 2°, which can achieve higher picture contrast, making the black deeper and the white brighter, thus presenting a more three-dimensional and layered picture.
Wide color gamut:The three-color laser light source can achieve more than 90% of the color gamut coverage of the natural colors seen by the combined eye, and even the color gamut coverage can reach 110% bt2020。In terms of color reproduction, it has a wider range of colors, and it is closer to the color of the real world, and there will be no color distortion and whitening.
Longer service life:Compared with traditional bulb or LED light source technology, the three-color laser has stable light and a longer light source life, which can basically reach more than 20,000 hours.
However, in the past, the cost of three-color laser technology was relatively high, and most of them were used in projection product lines or laser TVs above 10,000 yuan, which made many consumers hesitate before purchasing. And this problem has also been solved with the blowing of the wind of technology in the past two years,Manufacturers continue to roll up technology,Let the application cost of three-color laser gradually decrease,It can be applied to home projectors with a price of less than 10,000 yuan,Ordinary consumers can also buy and use。
At the same time, the increase in popularity has also aroused the jealousy of other manufacturers, and directly branded speckle as a shortcoming of three-color lasers, which discouraged ordinary consumers.
There may be some friends who are new to projectors and do not understand what speckle is. Let's start with a brief science popularization:
Speckle is a physical phenomenon of reflected light. Because the light is reflected on a rough surface, when the light wave encounters a small irregular surface structure, it will diffract and interfere, forming a speckled light and shadow alternating between light and dark. This phenomenon is usually easy to observe in scenes such as projection, where the projection screen has a frosted texture, a strong sense of smearing, and light and dark markings.
The high purity of the light of the three-color laser makes this light coherence phenomenon obvious and easy to see by the human eye. The MalC meckrypton TM three-color laser light machine independently developed by the nut brand is integrated with LSR dynamic speckle dissipation technology to achieve a speckle elimination rate of 97%, which has reached the standard of invisible to the naked eye.
So what are the core technologies of this newly developed three-color laser optical machine?
1) 400-zone four-layer compound eye homogenization system.
This system is mainly through 400 partitions of ultra-high-precision diffusion lens, to achieve micron-level fine diffusion, while ensuring the brightness of the picture, can evenly distribute the light source, so that the color and brightness of the picture are more uniform, and reduce energy consumption.
2) Modular laser stacking technology.
This technology is to reduce the size of the laser and improve its optical efficiency and heat dissipation performance through the modular design and stacking of the laser. For example, the laser projector of the nut N1 series has saved about 30% of its cost and reduced its volume by about 40%, making it easier to carry and use.
3) LSR dynamic speckle dissipation technology.
This is a technology developed by nuts to effectively eliminate laser speckle in response to the aforementioned speckle phenomenon. Last year, it successfully eliminated 96% of the speckle in the picture, and this year, Nut has increased it to 97%, making the speckle imperceptible to the naked eye, further improving the user's viewing experience.
To sum up,If you want to try three-color laser projection,And there are certain requirements for home theater construction,Then you can consider the flagship model of the nutN1 series,From hardware configuration to software debugging,It is the head of the industry,It can bring a better projection experience。
【Nut N1S Pro】
The emergence of Nut N1S Pro meets the higher quality needs of consumers. It combines the three-color laser and the 4K shock, further exerting the advantages of the three-color laser.
Nut N1S Pro is equipped with Nut's self-developed Malc Krypton three-color laser light machine, its brightness can reach 2000CVIA lumens, the contrast ratio can reach 1600:1, and the color gamut can also cover 110%BT.2020。Coupled with it4KThe ultra-high resolution,The picture quality of this projector has been greatly improved,The texture is excellent,It is far ahead of the projection products at the same price。
At the same time, it also has LSR dynamic speckle removal technology to interfere with speckle discrepancy, which can achieve a 97% speckle removal rate, bringing a more immersive picture effect to viewers.
In addition, it continues the nut's one-piece gimbal design, with a base that supports 360-degree rotation and a stand that supports 135-degree tilt adjustment. The silky damping design, coupled with the flexible gimbal picture correction function, adjusts the angle and the automatic picture correction function in seconds, allowing consumers to adjust the projection angle as they like, realizing instant picture correction and ensuring that the viewing process is more convenient and comfortable.
