In the summer of August, Jimi Technology held the 2022 technical communication meeting in Chengdu, where its headquarters is located, and the first new brightness standard for home projection, the Cinema Color Bright Standard, was released at this meeting, and the first projector equipped with their own CCB color brightness standard- Jimi H5 was officially launched.
ANSI brightness standard has always been the specification of manufacturers' production, and the film color brightness CCB standard released by Jimi is based on the two aspects of color and brightness, "grasping with both hands", breaking the previous industry's brightness parameter supremacy.
But in fact, friends who pay a little attention to the projection industry know that as early as half a year ago, another projector manufacturer, JMGO Nuts, has released the latest J series flagship product that focuses on primary color projection - Nut J10S.
Jimi and nuts are also the industry's leading manufacturers, can make a big fuss about the color reproduction ability in the development of new products, on the one hand, it shows that the development trend of the entire projector must also take the color direction, on the other hand, it confirms the unique vision of nut projection in the field of foresight.
The performance of color is the best way to measure the projector
Early home projection, brightness and contrast are generally not high, so early users will not pay too much attention to the color performance of the projector, most of the user's needs are to be able to see, there is no higher requirement for the brightness and detail of the picture.
However, as users' requirements for projectors are getting higher and higher, the color reproduction ability of projectors is also constantly improving, not only requiring clear picture quality at the same time, but also accurately restoring colors.
It is based on this background that Nuts and Leica's color masters have formed an expert technical team to make the Nut J10S bring users an immersive feeling by realizing the color presentation of the D65 standard (6500K color temperature).
Friends who may know a little about photography and digital circles have heard of "Leica", which is an international company with an optical engineering team with hundreds of years of technical precipitation and the world's top color tuning and other imaging technologies.
In the research and development process of nut J10S, the expert technical team automatically calibrates the white balance and gamma curve through the automatic white balance correction technology developed by nuts to ensure that the picture can stably achieve the D65 standard (6500K color temperature) color standard.
Here to give you a concept of popular science, that is, the D65 standard (6500K color temperature), D65 light source is the most commonly used artificial daylight in the standard light source, and its color temperature is 6500K. The D65 light source in the standard light source box is a simulation of artificial daylight, in order to ensure that the color effect of the object is observed indoors and on rainy days, there is a lighting effect similar to that observed under the sun.
Therefore, using the D65 standard (6500K color temperature) to calibrate display devices and other display devices can make the display device most realistically restore the natural things that our human eyes see. That is to say, the nut J10S can maximize the restoration of color authenticity.
Satisfaction with the quality of sound and painting is the standard of comprehensive experience
The projector, in the final analysis, is still a video and audio product, so in addition to the outstanding presentation ability of picture quality, it must also have strong audio performance. Good sound quality can bring better enjoyment to users.
This time, nuts are still in conjunction with old friend Dana, tuning nut j10S. As a world-famous audio manufacturer from Denmark, since its establishment in 1977, Tanner has always adhered to the goal of "reproducing the real and beautiful sound and making life more colorful", and has launched a variety of world-renowned car audio and home HiFi speakers and other products.
This time for the nut J10S tuning, the same is the use of high standards of home HiFi speakers, the use of 2 8W strong rubidium magnetic horn, laid the foundation for the perfect sound quality presentation, after the chief acoustic engineer for post-tuning, so that the three-frequency performance is more balanced, medium and low sound is sufficient, the treble is moderate, and the auditory sense presents a warm, elastic comfort. The overall acoustics are comparable to professional-grade effects, and users don't need to configure the audio for the projector at all.
In addition, for the projector, the heat dissipation system is also an important parameter to measure the projection, and the quality of the heat dissipation also directly affects the service life of the projector. If the air outlet temperature is too high, the light source and the motherboard will not be able to dissipate the heat, resulting in an increase in the temperature of the electronic components, which will eventually cause damage to the projector. In order to improve the heat dissipation efficiency, the projector's fan will always be in a full load state, and the faster the speed, the louder the noise will be.
Nut J10S solves the noise problem very well, the selection of a large diameter axial fan for high-end host and server heat dissipation, its biggest advantage is that the heat dissipation efficiency is higher, more quiet, with nut self-developed intelligent temperature control algorithm, can adjust the axial fan speed according to the ambient temperature and CPU temperature, so that the internal electrical components can always work in a safe temperature environment.
This ensures that the Nut J10S can continue to stabilize 22dB low noise even in the high-brightness state, achieving a few levels in the entire industry. The lower noise allows users to fully enjoy a more immersive viewing atmosphere without being disturbed by sound other than the source.
So nut J10S is indeed more outstanding in performance, coupled with a price of several hundred pieces lower than the jimi H5, whether from the cost performance or from the color performance ability, Xiaobian is more inclined to recommend everyone to choose nut J10S.
