In recent years, various home projectors have emerged in an endless stream, and it is difficult for consumers to choose, and it is not clear which is better or worse for a while. In fact, the choice is also very simple, starting with the most essential picture quality performance. WhileThe light source determines the brightness, color and longevity of the projector picture. This article starts with the light source, briefly describes the advantages and disadvantages of projectors with different light sources, and gives a detailed introduction to the laser light source.
At present, there are three types of projection light sources on the market: bulbs, LEDs, and lasers.
The light source of the bulb has high brightness and vivid colors, and compared with the other two types of light sources, it has a high heat generation, short life and high maintenance cost.
LED light source has long life, small size, environmental protection and energy saving, and is one of the mainstream light sources at present. Its biggest disadvantage is that the brightness is low, the color gamut is narrow, and the picture is easy to turn white and gray.
Laser is currently the purest and most perfect light source, with the advantages of high brightness, high color gamut, high contrast, high image quality, etc., is the best choice for home projection light source.
According to the research data of Lotu Technology, in the third quarter of 2023, the market share of laser light source projection will reach 52%, with a year-on-year increase of nearly 90%. Laser light sources are accelerating their penetration and will replace LED light sources as the mainstream light source for home projection in the future.
At present, there are three types of laser light sources on the market: trichromatic lasers, monochromatic lasers, and light mixing technology.
[Classification of laser light source].
1. Monochrome laser
Monochrome laser is a transitional technology developed by manufacturers in order to join the laser projection track, and the current representative technology is ALPD20, the old technology developed in 2012, known as breaking through the difficulty of brightness. It uses a single blue laser beam to shine on a phosphor wheel to excite red and green colors to create a picture of different colors. Compared with LED light sources, the brightness of monochromatic lasers is much higher.
However, due to the congenital lack of red and green light, the blue laser is required to irradiate the fluorescent color wheel to emit light, which produces a lot of stray light, which leads to the decline of the purity of the lightFiltering too much stray light in order to maintain the color of the picture will cause the brightness of the picture to decrease. That is to say, the color accuracy and brightness of the monochrome laser cannot be met at the same time.
2. Light mixing technology
The mixed light technology was introduced into the Chinese market by Casio in 2010, because the domestic projection market was not mature enough at that time, and the product was priced high, so it did not make much splash, and it was quickly eliminated by the market. Due to the rising popularity of laser projection, major brand manufacturers are seeking breakthroughs in light source technology, and this technology has been used in projection products.
From a principle point of view, mixed light is composed of a monochromatic laser + a full-color LED light source to achieve the effect of color balance and brightness improvement, the so-called 1 1 2. However, the disadvantages of this technology are also very obvious.
The monochrome laser lacks two colors, and the light source is still LED light, which cannot play the role of a real laser. And the LED lamp beads must cooperate with the intensity of the laser to improve the light effect, balance the color of the picture, and the power of the LED lamp beads is easy to burst the table when running at high intensity for a long time, and the operation is hot, the color decay occurs, and the product life is greatly shortened.
3. Three-color laser
The principle of trichromatic laser technology is to rely on three independent lasers to emit red, green and blue light, which can be directly imaged without passing through the fluorescence color wheel. Its advantage is that the brightness can easily reach more than 2200CVIA lumens, and the picture brightness is higher, and it will not be distorted and grayedThe color gamut can reach 110% btThe range around 2020 is more than twice that of monochrome lasers and LED light sources.
Compared with the same picture, the brightness of the three-color laser will be much higher than that of the monochrome laser, the picture is clear and uniform, there is no gray and dark around, and there is no color cast, and the visual effect is better. At the same time, the luminous efficiency of the three-color laser is higher, and the brightness increase will not produce too much power consumption, which will not affect the life of the light source.
So, isn't it very expensive to use such a high-end technology on a home projector?
In the past, due to the small scale of red laser production, the laser luminous efficiency allocation technology was relatively complex, resulting in the cost could not be reduced, so the technology was basically used in high-end laser TVs or projectors of high-end models of more than 10,000 yuan, which was out of reach of ordinary users. Monochrome laser is developed by manufacturers in this context, and it is a low-cost light source scheme, and the "laser" gimmick is greater than the reality.
In recent years, with the unremitting efforts of leading enterprises such as nuts, three-color laser technology has been improved and upgraded, and finally the technology has been inclusive, and many cost-effective three-color laser projection products have appeared. For example, nuts have independently developed the "Malc Meekrypton" three-color laser light machine, realizing the perfect combination of three-color laser and home projection, and directly applying this technology to the 3K price projection entry model, so that the top technology can enter more people's homes, so that more users can enjoy the ultimate visual experience.
To sum up,Compared with monochrome laser and mixed light technology,Three-color laser really uses red, green and blue three-color laser,It is currently the highest technical content,Brightness、Contrast、Color gamut and other aspects have reached the best laser light source scheme,It has been the consensus of major projection manufacturers,It is only a matter of time before it becomes the mainstream of the projection market。
If you want to buy a home laser projection,Three-color laser is preferred at the same price. Of course, tricolor lasers are good, but everyone's needs are different. Below I will recommend a few laser projectors with good performance according to the light source technology.
