Hello, here, I'm Kankan.
Why do you need a projector?
As a busy worker, the daily pace of life is really fast. When I get home, the best way I can rest is to gently close the curtains, lie down on the comfortable sofa, and light up the projector in the corner to create a home theater atmosphere. Immerse yourself in your own world in a relaxed and comfortable viewing environment and enjoy a classic movie that is very exclusive to me. If you want to create such an atmospheric leisure life, you don't need much investment, just a projector is enough!
As a home viewing device, the projector has many advantages that are unique! When purchasing a projector, it is recommended to start with a three-color laser projector. Because the laser light source has higher room for improvement in the brightness and color of the picture, it has inherent advantages from the light source. At home, you can enjoy the same shocking and immersive movie-watching experience as the cinema!
Choose a projector = choose a picture quality = choose a light source! What is the difference between tri-color laser projection and LED and monochrome laser?
Smart projectors are very popular in the market, and their light sources have undergone a series of changes, from traditional light bulb machines to LEDs, to monochromatic lasers and trichromatic lasers. Although the structure of smart projectors is roughly similar, they are all composed of a light source, a display chip, a prism and a projection lens that are used to project the picture. However, the biggest difference lies in the choice of light source. Many people pay attention to the brightness, color, and contrast of the projector, and these indicators are mainly affected by the light source.
Emerging light source technologies offer many advantages over traditional light bulb machines. For example, LED and laser light sources have a longer life and lower energy consumption, generally have a service life of 50,000 hours +, and will not produce brightness attenuation after thousands of hours of use like a bulb machine (the light source projector of the bulb machine has the characteristics of fast luminous attenuation of the bulb, high heat dissipation demand, large body size, high fan noise, and not easy to miniaturize, and it is rare to see new products launched in the home field, and the following discussion mainly revolves around the common three-color laser, LED, monochrome laser home smart projector). At the same time, it can also provide very good brightness and a wider color gamut. In addition, the three-color laser light source also has better color performance and contrast, which can present a more realistic and vivid picture. With the continuous advancement of technology, the light source of smart projectors has become more advanced and diversified, providing users with a better viewing experience.
What is the difference between tri-color laser projection and LED?
First of all, let's take a look at the characteristics of LED light sources.
The LED light source used in LED projectors is a mixed projection of red, green and blue LED light sources to display various colors. When projecting a screen with a relatively small size, the LED light source can also provide a relatively good viewing experience, but when projecting a relatively large picture, the disadvantage of the innate lack of brightness of the LED light source is highlighted. Because with the increase of the projection area, the projector needs to have a higher brightness as a support, otherwise the enlarged picture may be blurry due to insufficient brightness.
Since the LED light source emits light waves with a wavelength range of 30~40nm, it will not reach a very accurate degree in color performance. And LED light beads have a certain degree of scattering (laser is a linear light source, LED light beads are a scattering light source), so if the LED light source wants to improve the brightness, it cannot be achieved by increasing the density of LED light beads, because that will cause the light beads to be too close, and the light emitted between different light beads will affect each other. And LED is a kind of "heat light source", to improve the brightness of a single lamp bead, and the heat dissipation can not be suppressed!
There are certain similarities between three-color laser projection and three-color LED projection, but compared with three-color LED, three-color laser has achieved a comprehensive improvement. First of all.
As a cold light source, the three-color laser does not have as much heat dissipation pressure as the LED, so the brightness of the screen is greatly improved by increasing the density of the light source. The simplest example is that there are many laser halls in movie theaters, and the screen size of these laser halls often reaches the thousand-inch level, which is enough to see from the side how good the large-size projection ability of the laser light source is.
In addition, the light wave range emitted by the LED is more like a sine waveform in the positive range, taking red as an example, the red light released by the LED is a 30~40nm range of light waves containing positive red, red yellow/red purple, which leads to the purity of the color of the LED is not enough. The three-color laser can emit a pure color laser, and its red color is the positive red without variegation, so the light color emitted by the three-color laser is more pure!
It is precisely because of such characteristics that the three-color laser light source is ahead of the LED light source in six of the seven factors that determine the human eye's perception of image quality, such as color accuracy, color depth, color gamut, brightness, contrast, uniformity and resolution. In addition, as a laser light source, it also has more advantages than LEDs in eye protection, because the blue of the laser light source is pure blue and does not contain 400~450nm blue light. The blue color of LEDs contains "variegated colors", which contain blue wavelengths of 400-450 nanometers, which are harmful to the human eye. It can avoid the damage caused by blue light.
Therefore, through the above comparison, it can be seen that compared with LEDs, three-color lasers have obvious innate advantages. This is why the main flagship projectors and laser TV products on the market have invariably chosen the three-color laser light source as the standard. LED light sources are often only used in entry-level models with smaller projection sizes and less demanding color accuracy!
What is the difference between a tri-color laser and a monochromatic laser?
In addition to the tricolor laser projector, there is also a monochrome laser projector. When purchasing, you need to pay attention to the difference. The monochromatic laser light source is different from the trichromatic laser in that it only uses a blue laser light source, and then through the blue light source, after passing through the rotating color wheel, red and green rays are formed. However, due to the different principles of luminescence, only the blue light picture is relatively pure, while the other colors have a relatively large color cast. The color gamut covers only 50% of the BT.2020 color gamut (the three-color laser light source projector can often exceed 100% of the BT.2020 level). It's not even as good as some high-end LED light sources, so you should still start with a three-color laser when buying a high-end projector.
Is the three-color laser perfect?
In fact, it is not, three-color laser projectors have always had speckle phenomenon. It is precisely because the laser is such a perfect linear light source, and has the characteristics of high purity and high phase consistency and high frequency uniformity. Therefore, when the light waves are projected on a surface that is rougher than your own light waves, the light rays may interfere with each other. As a result, even the slightest unevenness of the reflective surface will be magnified and speckle will appear. It can be said that the reason for this is not because the three-color laser is imperfect, but because the three-color laser is too perfect, so this phenomenon occurs.
However, when we watched the movie in the laser hall, we didn't feel speckle, why is that? Because in the laser screen of the laser hall, there is a high-frequency motor to vibrate, so as to eliminate the high consistency of the laser, so as to eliminate speckle. The wall used in the home cannot emit high-frequency vibration like the theater screen, so how can the home three-color laser projector deal with the speckle situation? In the face of the speckle problem in the projection industry,Each company has adopted different strategies,Take the nut projector as an example,Equipped with the eye krypton optical machine,It adopts the industry's first LSR dynamic adaptive speckle dissipation module technology,It is to replace the high-frequency vibration of the screen in the traditional laser theater with high-frequency vibration of the optical path,In this process, 97%Speckle can be eliminated,Get a pure picture。 Therefore, in the process of purchasing a three-color projector, you must start with a product with speckle elimination technology.
Why is the gimbal of a projector important?
In addition to the light source of the fuselage and the workmanship configuration of the fuselage,The projector also has a "little thing" but it is more torturous,Placement for daily use,Because projection imaging is from a small fuselage to play a large picture,A slight change in position will affect people's viewing experience,And if you work moving, it will affect the daily use experience。 Now the projectors all support automatic screen entry、Automatic obstacle avoidance and other functions,You can quickly adjust the picture,Although the picture can be carried out automatically,But it is very troublesome for the machine to move around manually。 Therefore, when you start a projector, it is recommended to choose a model with a flexible gimbal.
Nuts are the first in the industry, and some people may simply think that this is not a scaffold? The gimbal is not a stand,But a customized gimbal with an algorithm for real-time picture correction,Compared with ordinary models,When the position of the picture is not very suitable,You can easily adjust the left and right directions,When the height is not enough,It also avoids the embarrassment of giving the projector under"pad book"。 In addition, when projecting the ceiling and other positions, there is no need to prepare special accessories, and the ceiling projection can be realized directly by turning upwards, which is very convenient.
Three three-color laser projectors at different price points are recommended
I have said so much earlier,I believe you have a relatively full understanding of projector products。 Here are three three-color laser projector products worth buying this year.
