The light source determines the picture quality, and the core upgrade direction of the home projecto

Mondo Digital Updated on 2024-01-19

In recent years, home smart projectors have become the new favorite in the home appliance market, with large-screen immersive experience, intelligent humanized operation and lightweight and portable models, which have been favored by more and more young people. According to data released by Lotu Technology, it is expected that China's projection shipments are expected to exceed 7 million units in 2023 and reach 9.5 million units in 2027.

At present, the projectors on the market are generally divided into traditional bulb machines, LED light source projection, and laser light source projection that has broken through the circle and seized the market with the trend of a dark horse in recent years. Now that laser technology is becoming more and more mature, major projection manufacturers are also constantly releasing laser light source projection, trying to occupy a dominant position in the home projection market.

Different from the short life of the bulb machine and the low brightness of the LED light source projection, the laser light source projection can bring a higher quality viewing experience with its excellent brightness, wide color gamut and long life, and has quickly become the first choice for young people to create an ideal viewing space. The data shows that the proportion of laser light source projection in intelligent projection is gradually increasing.

So, what exactly is a laser light source?

Let's make a clear concept first: the light source basically determines the image quality of the projector. As a household appliance, the projector is not as fast as the replacement frequency of FMCG, and it is basically replaced when it is broken. In addition, the intelligent functions of home projection are basically the same,There is not much difference in hardware parameters,So choose a suitable projector,The focus is on light source technology。

The solid-state laser is used as the light source, with low power consumption and a life of up to 20,000 hours, which is 10 times that of the traditional bulb light source. And it is directional luminescence, not easy to be disturbed by the external environment, has the characteristics of wavelength selectivity and high spectral brightness, and can technically close more than 90% of the color gamut coverage of natural colors seen by the eye, and the picture quality and color are more pure, with a high degree of reduction and a strong sense of comfort. It can be said that the laser light source is the future direction of display technology and is bound to become the mainstream of the market.

At present, laser light sources are mainly divided into three categories: monochromatic laser, mixed light and trichromatic laser. Among them, the three-color laser is the most advanced, mature and practical technology at present.

Classification of laser light sources].

1.Monochromatic laser.

The monochrome laser gimmick is larger than it actually is. Due to the high cost of three-color laser in the early stage, manufacturers have developed this technology in order to accelerate their entry into the laser projection track, which is low and lame. It mainly uses a single blue laser to excite the fluorescent color wheel, and then separates the red, green, and blue colors through the prism, and finally combines them to form different colors and pictures. The picture is clear, the color reproduction is good, and it is much stronger than the LED light source projection.

However, its color purity is not high enough, and it is easy to produce the phenomenon of color bias in the picture, which has not been solved so far. This is due to the fact that monochromatic lasers naturally lack two colors and need to be emitted with the help of a fluorescent color wheel. The light emitted in this way no longer has the characteristics of the laser, and a filter is needed to filter out the excess stray light, so as to improve the accuracy of the red and green light. If you want high brightness, you need to reduce the filter band, and then the color purity is not high enough. Therefore, the brightness of monochromatic lasers is either not greatly improved, or the color deviation is too large, and the image quality is reduced. At present, the ALPD laser technology is the best done in China, but no matter how iterative and upgraded the technology, the problem of color cast always exists.

2.Light mixing technology.

The color mixing scheme of single red laser source + LED light source is used to try to combine the advantages of monochrome laser and LED light source to achieve the effect of 1 1 2. This technology solves the problem of insufficient brightness of the projector to a certain extent, and eliminates the problem of color cast.

However, due to the fact that the technology itself only has a red laser and lacks blue and green two colors, it needs to be supplemented by LED light sources. However, the brightness and purity of the LED light source are far inferior to the laser, and the color effect of the picture is still not good enough. In addition, the long-term operation of the LED light source will also lead to heating, accelerate color attenuation, and reduce the service life.

3.Three-color laser.

This is what we often call "laser projection". It mainly relies on three different wavelengths of lasers to emit red, green and blue primary colors, and then project them onto the DMD projection chip to form different colors and pictures. The technology produces very pure colors with no stray light at all. The color gamut can reach an extremely high level, and its coverage can reach 90% of the color gamut range of the human eye, which is twice that of LED light sources and monochrome laser color gamuts.

The light emitted is strong enough and pure, which can present a better picture performance: the image quality is high-bright, high-definition and lossless, the picture color is realistically restored, the transition is natural and smooth, and the effect is excellent, which maximizes the advantages of laser technology. And the technology has low power consumption, long life, and very low maintenance costs.

If you have to say that there are any shortcomings, that is, the application is high, and the products are generally not less than 10,000 yuan. But after several years of technical overcoming, there are already brands, such as nuts, HisenseVidda, etc., which apply this technology in 10,000-yuan household smart projector products.

To sum up, when buying home smart projection, you only need to remember one principle: three-color laser, mixed light, monochrome. If you want to feel the joy of watching movies on a large screen, you should give priority to three-color lasers at the same price. Below I also briefly recommend a few three-color laser projectors with very good overall performance, for your reference!

For those who want to create a professional-level cinema experience at home, the Nut N1S Ultra is the best choice.

3. Hisense Vidda C1 series.

vidda c1s

Vidda is a young laser projection trendy brand owned by Hisense。 The Vidda C1S uses LPU three-color laser technology, with a projection brightness of up to 1600CVIA lumens, and is compatible with various light source modes. It's just that compared with products at the same price, the brightness performance is not outstanding, or even low.

The color gamut reaches 110% BT2020, the colors are rich, and the transition between different colors is natural. It is equipped with 0The 47DMD micromirror chip can fully meet the needs of viewing and entertainment in the 4K era. The hardware parameters are very good, but the appearance is biased towards the "tough guy style", the metallic sense is too strong, a bit bulky, and the aesthetic aspect is different.

vidda c1 pro

The Vidda C1 Pro uses ultra-high-definition tri-color laser technology with 2350CVIA lumens brightness. Like the Vidda C1S, the brightness effect is not as good as that of the price point. Even the Vidda C1 Pro only achieves 2350CVIA at the price of 9,000, which is a bit crotch-pulling.

With the help of the high-quality picture display ability of the three-color laser, whether it is a movie, a sports event or a game, you can feel the clarity and reality of every detail. It also supports 240Hz high brush rate, the game screen is smoother, and the response is more rapid, which is a qualified home audio and video tool. Similarly, the boxy look is more suitable for use with brackets or fixed to the ceiling.
