After companies such as Nut Projection launched a series of three-color laser projectors, three-color laser technology ushered in a fire moment. Compared with the projectors that only relied on autofocus, automatic screen alignment, intelligent obstacle avoidance, wifi6 and other function updates, the three-color laser projector has the advantage of the core picture effect, so that the projection picture can achieve a qualitative leap, and now the product pricing is in line with the main consumption segment of the public, ordinary families can also buy, the recommended list of projectors for each household at the end of the year began to appear frequently three-color laser projectors, and the public provides a convenient way to realize the construction of high-quality cinemas at home.
1. What are the core parameters of the projector?
As a viewing display device, the picture quality performance of the home projector is directly related to the user's sense of product experience. When choosing a projector, parameters related to image quality become the primary factors of concern, including resolution, brightness, color gamut, and contrast, which together constitute the image quality performance.
However, when evaluating the quality of a projection, you can't just look at one parameter, but you need to consider all aspects comprehensively. For example, even if the brightness is high, if the color gamut and contrast are low, the overall image quality rendering will appear average. Therefore, when choosing a home projector, these parameters need to be carefully observed and compared to ensure that a satisfactory visual experience is obtained in the end.
1.Brightness. Brightness refers to the intensity of light output by the projector to the screen, i.e., how bright the projected image is. Its nominal unit is "lumens", and in China, the common brightness standards are ANSI lumens (American standard) and CVIA lumens (domestic industry standard), of which most of the domestic CMIA lumens standards are used. In the case of all the same indicators, a high-brightness projector can indeed provide a better viewing effect than a low-brightness projector.
If you don't know how to choose brightness, you can refer to the brightness requirements of the following application scenarios:
Completely dark environment (no fingers can be seen): at least 500 cvia lumens;
Weak light during the day (cloudy) or weak light at night: at least 1000 cvia lumens
Use the lights at night: the brightness should reach at least 2000 cVIA lumens
Daytime bright room: the brightness reaches at least 3000cvia lumens.
2.Color gamut. The color gamut refers to the range of colors projected by the projector, that is, the color space, and the wider the color gamut, the richer and fuller the color presentation. Generally speaking, LED projectors use the SRGB color gamut standard, while laser projectors use BT2020 standard. bt.2020 is a high dynamic range wide area color space standard developed by the International Television Union (ITTU) that covers about 75% of the color range visible to the human eye. In comparison, the SRGB standard only covers about 35% of the visible color range.
3.Contrast.
Contrast refers to the ratio of black to white in the picture, the larger the value, the richer the gradient level, and the more vivid and layered the color is presented. Conversely, a low-contrast image may appear gray. Especially in darkfield scenes, the improvement of contrast is of great significance for the improvement of detail performance and clarity. If the content of the projection is mainly text and black and white**, the contrast ratio is about 400:1 is enough, but considering that the vast majority of home users are more inclined to**dynamic pictures, such as movies or game screens, etc., the picture contrast needs to reach at least 1000:1 or more.
4.Resolution.
Resolution refers to the clarity of the picture projected by the projector lens onto the wall. The resolution of a projector is mainly related to its display chip. There are generally three resolutions of daily home projectors:It is 720P (entry-level, suitable for projecting small and medium-sized screensP (high-definition resolution, suitable for large screensK (ultra-clear resolution, suitable for large screens).
In addition to the resolution is determined by the projector display chip, the three key parameters of brightness, color gamut and contrast are determined by the light source technology of the projector, so the light source advantage of the three-color laser is in
Second, why can the three-color laser greatly improve the projection image quality?
1.Brightness. The brightness of a projector depends critically on the intensity of the light source. The light source of the laser is accurate, the luminous efficiency is high, and the attenuation rate is low, similar to the laser pointer used by the teacher in class, which can project a clear and concentrated point on the screen regardless of the distance. In contrast, the halo effect of LED flashlight projection increases with distance, resulting in a blurry picture.
Coupled with the strong controllability of the laser optical path, the brightness of the three-color laser projector can easily reach more than 2000CVIA (in contrast, the upper limit of the brightness of the LED light source is about 2000CVIA), and it can even reach 6-70,000 lumens.
2.Color gamut. The color gamut is the range of spectra produced by a light source. In a tri-color laser projector, the laser emits red, green, and blue lasers independently, which reflect off the DMD and form a colorful image. Lasers, on the other hand, emit a single color and unique wavelength, so when combined, they can project a wider and more vivid picture with a wider color coverage.
The three-color laser projector is capable of reaching 100% BTMore than 2020, far more than the coverage of the color gamut by LED projectors, is more than twice as much. This means that the three-color laser can present richer and more realistic colors, making the projected images more delicate and vivid, and bringing a higher level of visual enjoyment to the audience.
3.Contrast.
Contrast is an important factor in the influence of the divergence angle of the light source on the black-and-white contrast of the picture. The laser has high collimation, and its light divergence angle is only about 2%, while the LED divergence angle is about 105°, that is, the light of the three-color laser is more concentrated and stable.
Therefore, the picture contrast of the three-color laser projector can reach more than 1600:1. The high contrast ratio makes the shadows and bright light details in the picture more visible, and the overall picture is more vivid. In the darkfield environment, the increase in contrast can maintain the depth of the picture, making the image more layered, and further improving the viewing experience.
Due to the natural light source advantages of the three-color laser,Directly shape the superior performance of the projector in the image quality parameters,Compared with the LED light source,Realize the "qualitative change" leap in image quality。
