The home projection market continues to promote technology upgrades and product iterations, and this year, laser projection products are blooming everywhere. XGIMI, which has always insisted on high-power LED light sources, can't sit still,Launched XGIMIH6 Pro,A projection product with Dual Light super mixing technology。 As the leading brand of laser projection-nuts,First launchN1Series three-color laser products,Win the market with excellent performance and top technology,Among them, nutsN1S Pro has refreshed the cost-effective ceiling of home projection,Favored by consumers。
So,Today, let's compare the nut N1S Pro and XGIMI H6 ProThese two 6K price points4K laser projection products are different.
First, whether the picture quality is good or not depends on the light source first:
I believe we all know that the light source is the first choice when choosing a projector, because the light source determines the projection effect. The mainstream light sources in the market are mainly light bulbs, LEDs and laser light sources.
I believe everyone has been exposed to traditional light bulb machines in middle school. It is a projector that uses high-pressure mercury or xenon lamp as a light source, with high brightness, suitable for office or teaching use. But those who have used it know that it is large in size, high in power consumption, noisy after a long time, and has a short life, so it is not suitable for household use.
With the rise of intelligence, LED light source has gradually become one of the mainstream light sources in the projection market with the advantages of low cost, small size and long life, opening the door to home intelligent projection: 100-inch screen, relatively cheap, high portability does not take up space, and is favored by young people.
However, the defect of low brightness of LED light source has been unable to meet the user's demand for high-definition and bright image qualityEmerging light source - laser light source came into being, which has the trend of replacing LED light source as a new generation of display technology. Compared with ordinary light sources, laser has the characteristics of good monochromaticity (high purity), high brightness, strong orientation and collimation, and can be presented when used in projection productsHigher brightness, wider color gamut, and better image qualityprojection screen, andThe service life is up to 20,000 hours.
At present, there are three main types of laser light sources: three-color laser, monochromatic laser and mixed light. Among them, the monochrome laser is easy to cause the color shift of the picture, and the representative technology is ALPD laser display technology, and it is not the light source technology used in the two products to be compared today, so I will not explain it here.
The following is a detailed introduction to the three-color laser and light mixing technology in combination with the product.
Nut N1S Pro is equipped with Nut's self-developed MALC Krypton three-color laser light machine, that is, three-color laser technology.
Three-color laser is widely used in high-end laser IMAX cinema, which is currently the most mature and advanced laser technology. It uses three lasers of different wavelengths to emit light separately, because the laser monochromacy is very good, as long as the appropriate wavelength of the laser is selected, it can ensure that the red, green and blue trichromatic light emitted has almost no stray light, and the color purity is high, and the three-color laser is irradiated on the DMD chip respectively, and finally projects a picture of different colors on the screen.
Since the lasers are separated, the tristiroic light is abundant and pure, covering 100% bt2020 even has a wider color gamut, so that the picture presented is brighter and clearer, the colors are richer and more vivid, and the degree of restoration is high.
The MalC Krypton three-color laser light machine equipped with Nut N1S Pro breaks through the limitations of early three-color laser technology, and innovatively develops a 400-zone four-layer compound eye homogenization system and LSR patented technology for dynamic spot dissipation. The former can improve the brightness and color uniformity of the picture and provide a highly comfortable visual quality, while the latter can solve the problem of image speckle and achieve a picture effect that is not perceived by the human eye.
Friends who pay attention to the projection industry must often see individual netizens spreading the problem of three-color laser "speckle", as if "speckle" is a heinous crime.
In fact, speckle is a physical property of light, which refers to the granular appearance of the surface of an object irradiated by light. Due to the high purity of the three-color laser light, the divergence angle is small and concentrated, resulting in speckle that is easily detected by the naked eye. With the continuous iterative upgrading of technology, most brands have been able to achieve 90% speckle elimination, and the nut's LSR dynamic dissipation speckle patent technology can achieve 97% speckle elimination, making the picture more pure and delicate, the look and feel more comfortable, and you can't see any roughness in the picture at close range.
XGIMIH6 Pro uses Dual Light super mixing technologyIt is a light mixing scheme that adopts "monochrome laser + panchromatic LED". Use pure red laser to make up for the lack of LED brightness, and use panchromatic LED to make up for the shortcomings of monochrome laser color shift, achieve color balance, and claim to break through the limitations of LED while avoiding the problem of "speckle".
However, this kind of hybrid technology also allows the shortcomings of LED to be passed on. The color purity of LED panchromatic light is not high, which affects the purity of the laser, and cannot give full play to the color advantage of the real laser, and the color and contrast performance of the picture is still the range of LED light source. Moreover, the LED must run at high intensity to match the monochromatic laser intensity to make up for the missing blue and green light, and long-term operation can easily lead to excessive power consumption of LED lamp beads, and there will be light decay and shortened life.
Second, a wide color gamut can ensure accurate color reproduction
Nut N1S Pro color gamut coverage reaches 110% BT2020, and the contrast ratio reaches 1600:1;XGIMI H6 ProColor gamut coverage reaches 99.9%rec.709, contrast not noted.
The color gamut is defined by a specific range within the range of colors that can be recognized by the human eye (i.e., the visible spectrum). bt.2020 is the HDR color gamut, which was introduced by the International Telecommunication Union as early as 2012 for the 4K 8K era of standard color gamut. Three-color laser projection is currently the only display device that can exceed 110%BT2020Color gamut,Other light source projectors、TV、It is difficult to do it,Top OLEDTV can only cover80。
Nut N1S Pro has a 110% BT2020 ultra-wide color gamut and 1600:1 ultra-high contrast ratio, rich and delicate colors, natural and smooth!The light and dark levels are richer, the details of the picture are more prominent, and the shape and texture of the object can be clearly seen.
rec.709 is an international color standard formulated by the International Telecommunication Union in 1990 for HDTV high-definition television, and since then, most films need to be transcoded according to this color gamut standard when making hairstyles. XGIMI H6 Pro can cover up to 999%,There is a certain improvement compared to the pure LED light source,The color performance is okay,But compared to the nutN1S Pro, it is still a lot inferior。
3. Brightness comparison:
Nut N1S Pro brightness has 2000CVIA lumens, XGIMI H6 Pro is1920CCB.
Under the simple science popularization here,CVIA is led by the China Electronic Video Association,Nuts、Dangbei、Fengmi and other more than 10 enterprise representatives and e-commerce platforms,The first unified brightness standard in ChinaCVIAlumens was negotiated and formulated,Recognized and jointly supervised by the whole industry,There is no accurate conversion formula between CCB。 CCB is XGIMI's own brightness standard, which has no relevant associations and other industry manufacturers involved, and has not been internationally recognized. Therefore,XGIMI H6 ProWhat is the actual brightness,There is still a question mark。
Fourth, the appearance should be both beautiful and practical
In terms of exterior design, Nut N1S Pro is smart and exquisite, with outstanding appearance, and can easily be integrated into various home decoration styles. Break through the square design of traditional projection and adopt an innovative and practical one-piece gimbal design. That is, an integrated smart gimbal is added under the body of the matte material, which allows users to rotate the body body very easily and freely, supports left and right 360° rotation, up and down 135° wide range of adjustment, whether it is the wall or the ceiling, it can be easily adjusted, realize the freedom of viewing and enjoy the immersive experience of the whole scene, completely get rid of the limitations of space and angle.
The damping sense is sensitive and silky, and it can be adjusted and stopped at any time, with the gimbal image correction function, even if the device is moved, it can track the dynamics of the fuselage in real time, millisecond-level correction and focus the picture, and the picture can be kept square and clear at all times when the picture rotates, and truly realize non-inductive trapezoidal correction. There are also functions such as global automatic obstacle avoidance and intelligent anti-shooting eyes, which can be used immediately, and say goodbye to the troubles caused by manual adjustmentLittle white players get started quickly!
XGIMIH6 ProIt is still a traditional square shape,Adopt the classic rock foot gold color of the H series,Full score of texture,Relatively atmospheric。 The overall body is a cylindrical prism, with arc transition processing at the corners of the four periphery, and a clear lens module on the right side of the front, marked with the "4K Ultra HD" gold label. However, the size is slightly larger, and there is a sense of calmness, which may be related to the fact that the mixing technology requires space for heat dissipation. in addition,XGIMIH6 ProWhen using, you may need to adjust the projection angle with a stand or book,In order to present a better picture effect。
To sum up, from the perspective of light source technology, color performance, brightness and appearance comparison, Nut N1S Pro is still superior.
