At this year's XGIMI's 10th anniversary new product launch conference,XGIMI launched its new technology:Eye protection three-color laser technology,It also released its first entry-level three-color laser projectorRS10 mini,It attracted a lot of attention for a while。 After all, in May last year, XGIMI also publicly belittled the three-color laser technology at the spring press conference,I didn't expect it to follow the three-color laser in just three quarters,It seems that projection three-color laserization is no longer a trend,But now。
Presumably, friends who know something about the three-color laser will have questions,The blue light in the three-color laser can choose long-wave blue light,It already has an eye protection effect,So why doesn't XGIMI engage in pure three-color laser technology like the three-color laser giant nut、HisenseVidda, etc.,But find another way to launch an eye-protecting three-color laser? Is it a limitation of technology or is it attracting attention?
Eye care three-color laser: a combination of three-color laser + fluorescent materials
Previously, XGIMI launched Dual Light 10, the use of red monochrome laser and LED light source combination, although the brightness has been improved, but the contrast and color gamut under the influence of LED light is always far from the three-color laser, and a single red laser leads to the problem of color cast in the picture, and does not play the effect of 1 + 1 2, the market response is also average.
And the eye protection three-color laser is XGIMI dual light 2.0 light source technology, as dual light 1The continuation of 0 light source technology, its technical principle is to use the three-color laser as the dominant light source to improve the image quality brightness, contrast, color gamut and color accuracy, and at the same time add fluorescence to reduce the problem of speckle and color edge ghosting. Therefore, from a technical point of view, in essence, the eye-protecting three-color laser is still a kind of light mixing technology.
Pure tricolor laser
The real three-color laser technology is to use red, green, blue three narrow spectrum, high purity laser as the light source, higher brightness, wider color gamut coverage, better contrast performance, from the perspective of image quality expression, far more than any other light source. However, because the laser is a narrow spectrum, its high resolution leads to the formation of speckle on the projection screen. However, in the past year or two, the speckle problem of three-color laser has been solved.
As the head brand of three-color laser, the self-developed three-color laser optical machine of Nut has added LSR dynamic speckle technology, which can eliminate more than 97% of speckle and achieve the effect of speckle invisible to the naked eye.
Is the new concept of "eye protection three-color laser" launched by XGIMI slightly better? Compare with the product.
Product comparison: XGIMI RS10 mini and nut N1
Choose the same price as 3000 yuanXGIMIRS10 MINI and as a representative of pure three-color laserN1Compare the picture parameters,Let's see what the strength of the eye-protecting three-color laser is?
Comparison of light source parameters
Nut N1 and XGIMI RS10 MiniThe brightness and color gamut are the same,The brightness reaches 800CVIA lumens,Meet the needs of daily viewing。 The color gamut is also advertised to reach 110% bt2020, and XGIMI RS10 mini can switch between two light source modes: eye protection three-color laser, three-color laser. It should be noted that when the eye protection tricolor laser is selected, the color gamut cannot reach 110% BTIn 2020, how many color gamuts can be reached are not indicated. In terms of contrast,Nut N1Maintain a high contrast ratio1600:1,And XGIMIRS10 MINI has not announced this value。
Comparison of resolution parameters
From the perspective of resolution parameters, both can reach a resolution of 1080p, compatible with 4K resolution. On the display chip, the nut is 0The 33dmd chip, while XGIMI's is slightly smaller, is 023dmd chip. The larger the display chip, the resolution is about, and the clearer the picture, and 033dmd will be more light than 0The 23dmd is higher, and the picture is brighter.
Personally, I think that in fact, XGIMI can be mentioned 033dmd, after all, 023DMD is more widely used in LED projectors around 2000 yuan, and it is not very competitive at the price of 3000 yuan.
XGIMI launched RS10Three-color laser series products at the beginning of the year,It is also the first time XGIMI launched three-color laser technology products,But from the comparison of key picture parameters,It is not difficult to find,Eye protection three-color laser to"eye protection"and"Speckle removal"The main selling point,But compared with pure three-color laser,The expressiveness of the picture has been weakened,Color gamut and contrast are limited to a certain extent。 What the strength is, it remains to be measured on the screen.
