The continuous progress of technology has brought many changes to the way of life, and the transformation of home smart projectors for home entertainment is also significant: the large picture gives people a visual impact, close to the picture quality details and rich colors of the cinema blockbuster, the stereo surround sense brought by immersive sound, the small and portable installation method is extremely convenient, and at the same time can add atmosphere when gathering and gaming, it is a multi-purpose weapon.
As more and more young people join the ranks of smart projector users, their requirements for picture quality and clarity, product experience and eye protection performance are also increasing. They are no longer satisfied with smart projectors with 1080p resolution, but have set their sights on more advanced ones4K laser projector
Ceiling-level 4K image quality is inseparable from the blessing of leading light source technology。Otherwise,Even if you buy a 4K projector,But use a crotch-pulling light source,The picture quality presented in that way may be pseudo-4K effect,The picture quality cannot reach the best。
The projector light sources on the market are mainly divided into:Bulbs, LEDs, and laser light sources。The bulb has the advantage of high brightness, but the life is short, generally not more than 1500 hours, the maintenance cost is large, and it is commonly used in office or teaching purposes. LED light source has become the mainstream light source of home projectors with the best advantage,But soon entered the stage of weak product innovation,The brightness of the light source itself has an upper limit,At present, it is often used in low-end projection products。
The laser light source has:High brightness, high color gamut, high light efficiency and long lifeand other outstanding advantages, it has the potential to replace LED light sources and become the best solution for home projector light sources at present and in the future. In just a few years, the proportion of the laser projector market has grown rapidly, becoming the sweetheart of the projector market at this stage.
With the continuous development of laser technology, more and more brands have laid out laser projectors, and then developed a variety of laser solutions, so as to accelerate the penetration of laser projectors into the market.
The projection brand based on dangbei choosesALPDLaser display technology as the direction of product research and development,Created"DangbeiX series"Laser projection series products;XGIMI chose the color mixing laser as the direction and developed the dual light super light mixing technologyBrands such as nuts and Hisense Vidda have chosen the most advanced and mature three-color laser technology as the main research and development direction, and promoted the inclusion of high-end technology through self-developed three-color laser optical machines.
There are various theories, but there are only three technologies: monochromatic laser, mixed color laser, and tricolor laser.
Monochromatic laserA single blue laser is used to irradiate a rotating fluorescent color wheel, which emits red and green light, and then combines the lights to form different patterns. Because the red light and green light are emitted by the fluorescent color wheel, they do not belong to the laser in essence, the color purity is poor, and the color gamut value is less than half of the three-color laser, so the color performance of the picture is very poor, and the brightness is high, and the problem of picture color cast is easy to occur.
Color mixing lasersIt is a scheme that uses monochrome laser + panchromatic LED color mixing, with LED light sources of different wavelengths as complementary colors, and a single laser to improve brightness, so as to achieve a more balanced and real picture effect. However, due to the addition of only one kind of laser, the brightness and color gamut coverage are far less than the three-color laser, and the addition of the LED light source destroys the purity of the laser, as well as the problems of running heat and light decay, and it is easy to shorten the service life of the projector.
Three-color laserIt is to emit red, green, and blue primary color lasers through three independent lasers, and then combine the desired pattern and color on the screen. The advantages of this technology are obviousFirst, the brightness is extremely high。The mid-to-high-end projectors using LED light sources can only reach up to 3000ANSI lumens, while the three-color laser can easily break through the brightness of 3000ANSI lumens. Second, the color is full。The color gamut can reach 100% btIn 2020, it is 2 times that of LED, and the contrast ratio reaches 1600:1, which is 3 times that of LED, so that the picture presented is more vivid and vivid, real and natural.
Third, the life span is very long。The energy of the laser is balanced, the emission angle is small and concentrated, the luminous efficiency is high, and it is a cold light source, so there will be no problem of overheating, and the service life can be extended. Fourth, eye health。The three-color laser can eliminate the harm from the source by using long-wave blue light and avoiding the harmful short-wave blue light band, and the eye protection ability is very strong. The stray light of monochromatic laser contains harmful short-wave blue light, which is harmful to the retinal cells of the human eye, and the problem of fluorescent color wheel strobe is very unfriendly to the human eye.
So, why is the three-color laser technology so superior, but it has not been popularized on a large scale?
This is due to the high cost of the previous three-color laser technology,The product cost is also high,Only a small part of tens of thousands of yuan of laser TVs or super flagship projection equipment will be used。 Many projection manufacturers are discouraged, and finally choose the most inexpensive monochrome and mixed color lasers, in order to reduce costs, and can join the laser projector market with the gimmick of "laser". From the technical principle, it can be found that the monochrome color mixing laser is actually a "pseudo-laser technology", which has more or less technical defects and cannot play the effect of a real laser.
The tri-color laser is considered to be the best choice for home projector light sources。With the continuous development of technology, nuts and Hisense Vidda self-developed three-color laser light machine, overcoming the technical problems of three-color laser, controlling the cost, and allowing more users to enjoy the visual feast brought by high-end technology. Nuts are equipped with a self-developed Malc three-color laser light machine on their own 3000 yuan entry projection model, so that beginners can also enjoy the audio-visual charm of high-end cinema homology technology.
To sum up,From the perspective of the picture effect, the light sources are sorted into three-color laser, mixed light, monochrome laser and LED light source。And three-color laser technology and ultra-clear 4K image quality is the current picture quality ceiling of home projectors,The combination of the two,You can get excellent picture quality performance,Fully crush other light source projectors。 So, below I also summarize a few 4K home laser projectors, just for reference!
Nut N1S Ultra
Nut N1S Ultra is full of parameters, outstanding performance, and the picture effect is comparable to that of high-end 4K theaters, don't miss it!
It is equipped with a Malc three-color laser light machine, with 4K ultra-clear resolution, brightness up to 3000CVIA, and color gamut up to 110% BT2020, the contrast ratio is 1600:1, the picture uniformity is as high as 95%, and it can present a delicate and realistic picture, whether it is watching a movie, watching a game or playing a game, it can make users feel the clarity and truth of every detail, close to the texture of the original film, and is not afraid of the influence of ambient light, and can also present a clear picture during the day. Coupled with LSR dynamic speckle dissipation technology, 97% of the picture freckle is eliminated, achieving the effect of non-perceptual speckle dissipation for the human eye, and the appearance is more comfortable.
The appearance is excellent, the style is atmospheric, and it is versatile in various home scenes. With an integrated gimbal design, it can achieve 360° horizontal rotation and 135° vertical tilt adjustment, from the wall to the ceiling, you can cast wherever you want, greatly expanding the projection angle, and the angle is free and flexible. Coupled with the damping design, the one-handed adjustment angle is very silky, and the infinite hovering effect can also be realized, which means that adjusting the projection angle no longer needs to be manually fixed. With PTZ-style picture correction function, intelligent correction and focusing of the picture, if the projector is accidentally moved, it can also be quickly adjusted and focused, and the picture is always clear and square, which does not affect the viewing experience at all.
vidda c1 pro
Vidda C1 Pro uses LPU three-color laser technology, with 4K ultra-clear resolution, 2350CVIA lumens, which can meet the needs of daily viewing, but the brightness does not have an advantage in the same price range. 110%bt.2020 ultra-wide color gamut, δe 09. High color accuracy and 1700:1 contrast ratio, the color performance is true and delicate. Coupled with dual 10W high-power speakers, DTS 360° surround sound, Dolby DAP cinematic immersive sound and Viper sound, the sound quality performance is good, and you can listen to songs with the screen off. However, the appearance is average, the shape is too square and tough, and the official recommendation is to use it with a gimbal stand, which increases the cost of use.
XGIMI RS Pro3
XGIMI RS Pro3have2500CVIALight brightness,It can also be clear during the day**,Plus4KUltra clear image quality effect,The picture performance is very good。 It is also equipped with an eagle-eye vision system, and the projection screen can adapt to the environment and wall color, and there is optical color enhancement to improve the picture quality effect. However, it uses dual light super light mixing technology, that is, color mixing laser, and the color gamut is narrow, only 999%rec.709, the color performance of the same price is not dominant, which is a pity. It would be even better if it could be upgraded to three-color laser technology.
DangbeiX5 Ultra
DangbeiX5 Ultra has2500CVIALumens brightness,It belongs to the mid-range brightness standard at this price。 4K ultra-high-definition picture quality, custom color mode, high-definition and delicate picture. It is also equipped with MT9679 chip, 6+128GB large memory, smooth operation without pressure, plus non-inductive autofocus, automatic trapezoidal correction, automatic screen entry, intelligent obstacle avoidance and other functions, all of which are standard configurations at the price of 10,000 yuan.
However, ALPD50 super panchromatic laser technology, that is, the combination of three-color LED + three-color laser. Because the technology is too new, has not been tested by the market, and the essence is still a mixed color laser, the LED light source will affect the color performance, and there may also be problems such as pearl decay and life reduction of LED lamps. It is recommended that those who are interested in starting will wait and see.
