In recent years, home projectors have become more and more popular because of their convenience in providing cinema-level viewing at home. However, with the development of technology, the types of home projectors have become more and more complex, from LED projectors to laser projection to three-color laser projectors, leaving many people dazzled when it comes to choosing. The parameters seem confusing,Therefore,This article will take you to sort out how to buy a cost-effective home projector。
What are the functions of buying a projector to see?
Choose a home projector,When purchasing, you mainly look at two aspects,The first is to look at the picture effect,The second is to look at the value-added function。
Value-added features include speaker sound, mobile convenience, gimbal, system, app, etc. The functional experience is more personalized and can be chosen according to your preferences, and it is easier to distinguish the advantages and disadvantages, so I will not repeat them here.
Picture parameters include brightness, color gamut, contrast, and resolution. For home projectors, these four parameters are very important, which directly affects the viewing experience. If you want to have good image quality, these four parameters cannot be ignored.
Recognize the important parameters of the projector: brightness, color gamut, contrast, resolution
1) Brightness: Brightness is the energy output of home projectors, and it is also an important indicator to measure the strength of the projector.
2) Color gamut: refers to the range of colors that can be presented by home projectors, and the color gamut will affect the color richness and fullness of the projection, among which LED projectors are generally identified with SRGB, and more advanced REC. is used when using three-color laser projectors2020 logo.
3) Contrast: The ratio of brightness between the brightest and darkest points in the projected picture, the higher the contrast value, the more natural and layered the picture is excessive, otherwise there will be a gray feeling.
4) Resolution: also known as resolution, the higher the resolution, the more delicate the picture. The resolution can be seen in the parameters of the DMD display chip on the projector,At present, the DMD of the home projector is mainly 0.23dmd、0.33dmd、0.47dmd、1.38DMD four sizes, the corresponding resolution is 480p, 720p, 1080p, 4k, when choosing generally choose 1080p, 4k, better experience.
In addition to the resolution is to look at the size of the DMD chip, the brightness, color gamut, and contrast of these three parameters need to be looked at together, because they are all determined by the light source of the home projector.
Learn about the light source of the projector: bulbs, LEDs, lasers
1) Bulb: The traditional projector will use ultra-high pressure tribute lamp, which has the advantage of high brightness, such as the traditional brand Epson, BenQ and other lamp projectors. However, because the power consumption of the bulb is too large, the life is very short, and the heat is serious when used, and the projector is also larger, and it is less used in the home projector market.
2) LED: Using red, green and blue LED light to synthesize white light, then pass through the light diffusion system and project it through the lens, which is the light source technology that most brands will adopt. The low ** makes LED become the mainstream projector light source now, the advantage is that the energy consumption and life are better than the bulb, but the brightness is difficult to break through 2500ANSI lumens, and if you blindly improve the LED luminosity, it will lead to color imbalance.
3) Laser: Laser as a "pure light source",It has innate advantages in terms of characteristics,Its principle is to shine through the laser and irradiate it to the DMD chip to synthesize the required color,The representative brand is nuts、HisenseVidda, etc。 Because the laser has high brightness and high purity, it is used in the projector, and its brightness, color gamut and contrast are better than the LED light source, and as a cold light source, the energy consumption is lower, and it is truly energy-saving and environmentally friendly.
In general, in the choice of light source technology, laser LED > bulb. In the past, due to the difficulty of laser application and high cost, the laser projector was basically 10,000, which discouraged many families. In recent years, as more and more manufacturers realize the excellent performance of laser technology, and make breakthroughs in continuous research and development and innovation, the application of laser projection technology has gradually decreased significantly from the cost, and the product has dropped from tens of thousands of yuan to the range of 1,000 yuan, providing more users with a cost-effective choice.
Laser projectors need to pay attention to the following two aspects when choosing:
(1) Choose a three-color laser projector
In the laser projector, there are mainly two technical solutions: monochromatic laser and trichromatic laser.
Monochromatic laserThe principle is to use a blue laser to generate red-green light through a fluorescent color wheel, so as to form three primary colors. Because only one kind of blue laser is used, other rays are emitted by the fluorescent color wheel, which will produce a lot of miscellaneous light, which will affect the color performance of the picture, cause color cast problems, and the blue light content in the picture is high, and there is short-wave blue light that hurts the eyes, and it will cause eye fatigue and other problems for a long time.
Three-color laserIt is the use of red, green, blue three color laser luminaire independent light, higher color purity, and the three primary color light energy balance, color gamut coverage is wider, generally can reach 100% bt2020。At the same time, the three-color laser can achieve the eye protection effect on the hardware by screening the long-wave blue light that is harmless to the human eye.
Therefore, if you choose a laser projector, you can directly close your eyes and enter the three-color laser projector, which has more advantages in terms of picture color, brightness, and eye protection.
(2) Whether speckle affects the visual effect
Due to the fluctuating nature of light, when light passes through a lens or mirror, a small spot will appear near the focal point of the light, which is called speckle. That is to say, there is speckle in any light in life, just because the speckle distribution is irregular, so it cannot be seen by the human eye. The three-color laser has a high purity, making it easier for people to detect Sanban.
Nowadays, many theaters choose to use three-color laser projection, why can't we feel speckle when we watch such a large screen in the cinema?First speckle 3At 2%, the human eye is imperceptible, and if it is 5%, the human eye will be more likely to perceive the interference of speckle, so the theater is to make multiple, multi-group, and multi-band laser light sources at a higher cost to mix to reduce the speckle to less than 3% to achieve speckle invisible to the human eye.
In home projectors,It is nuts and Hisensevidda, two manufacturers that can inhibit speckle better,Nuts use self-developed LRSRdynamic speckle dissipation technology,Increase the dissipation rate to97%,Reach the standard of human eyesight。 HisenseVidda inhibits speckle through multi-dimensional dynamic speckle, so that speckle is weak. When choosing a home projector, you can consider the products of these brands for a more superior visual effect.
