CTOnews.com news, June 9, June 8, nut projection in Shenzhen Vientiane and other national landmark core business district, held by Phoenix New Media science and technology exclusive live "projection picture quality public showdown" national blind test activity, by randomly inviting passers-by to blindly select the form of three-color laser products (nut N1 Ultra) and "super mixed light" products (extreme rice RS Pro3) picture quality comparison experience In addition to randomly inviting passers-by to vote, 36Kr, ZEALER and other media witnessed the whole process of the event, proving that the event was fair, open and impartial.

According to official data, as of 19:00 on the same day, in the vote count of the main venue in Shenzhen, the nut tricolor laser product N1 Ultra had been selected by 83.76% of users.

The cause of this "public showdown of projection picture quality" was a video released by a UP master at Station B on May 26 to evaluate the above two different technical solutions from nuts and polar rice. In the video, UP said that polar rice's "contrast, color accuracy, and HDR algorithms are all very general."

Subsequently, Will, chief product officer of Nut projection, forwarded the video to moments and said: "if the so-called 'industry boss' does not use the real money given by users to promote innovation and progress after making the most profits in the industry, but uses shoddy cheap technology and money-burning marketing to reverse the industry, then the industry will not be far from death."

With the ferment of public opinion, on the evening of May 30, Jimi Technology, Nuts projection and UP hosts jointly broadcast the "debate" in Phoenix New Media's science and technology studio.

The whole discussion revolves around which tricolor laser or "super mixed light" is the stronger projection light source technology, and there is a heated discussion between the two sides. The main controversial point is that nuts, as proponents of tricolor laser technology, believe that polar rice has also stepped on the "tricolor laser" while releasing its own "super mixed light" technology, which is suspected of misleading consumers.

Chi Mi responded to it as porcelain marketing, and said "seeing is believing".

It is worth mentioning that the live broadcast topped the list of the most popular live broadcasts on Weibo that evening, attracting a total of 510000 people to watch it in real time. After the live broadcast, Ji announced that it would hold an offline experience event on June 9. Nut also announced the public showdown activity of projection picture quality, and said that the blind test activity would be launched simultaneously in the 16th city on June 8.

However, on the evening of June 5, Chi Mi suddenly announced the cancellation of offline experience activities. In response to this, Chi Mi said that "technology and products should be tested by the market and consumers", and that there would be no offline comparative experience. At the same time, it announced that there was no reason to return Ji Mi RS Pro3 for 30 days.

The "projection quality public showdown" on the nut side is going on as usual.

It is understood that on June 8, the two machines participating in the blind test at the main venue in Shenzhen were purchased directly by Phoenix New Media Science and Technology through the JD.com platform and brought to the event site, and the blind test machine was opened for the first time under the witness of many media and users. the test environment is a temporary darkroom, and the projection screen walls are ordinary latex paint walls, so as to maximize the real environment of users' daily viewing.

According to official data, by the end of the live broadcast at 19:00, a total of 117 consumers at the main venue in Shenzhen had participated in the blind assessment of projection picture quality, and the nut N1 Ultra, which uses MALC eye krypton ™tricolor laser technology, won with 98 votes. The other cities had a total of 97 votes and 94 nuts won.

At the event, Wang Xiaoyi, chief product officer of Nut projection, said that his evaluation had been as fair as possible, choosing one of the most populous business circles in Shenzhen, because enough consumers could vote spontaneously. Secondly, in the preparation of the evaluation machine, the four machines purchased entirely by Phoenix New Media did not have any participation.

According to official data, in this blind test, Nut N1 Ultra is equipped with a MALC eye krypton ™tricolor laser machine developed by Nuts for three years, with three core technologies: modular laser stacking technology, the first patented LSR dynamic speckle elimination technology and a 400-zone four-layer compound eye leveling system.

It is understood that modular laser stacking technology can increase optical efficiency by 10%, reduce volume by 40%, increase heat dissipation performance by 10%, bring 110% BT.2020 gamut and 1600 1 contrast performance; 400 zonal four-layer compound eye leveling system, achieve fine leveling of about 45000 small areas, uniformity can exceed 95%, and excellent improvement in brightness and color uniformity.

In order to solve the problem of speckle in tricolor laser, nut pioneered LSR dynamic speckle elimination patented technology on tricolor laser projection at home. Officials said that it can also achieve more than 96% speckle removal, making it almost invisible to the human eye.

In addition, the nut N1 series also uses an integrated head structure, which can be controlled by one hand through the self-developed ultra-thin two-axis head structure, easily rotate and hover freely, and hover freely within an adjustable range, covering all use scenes from the corner of the wall to the ceiling, whether sitting or lying down. At the software level, the depth combined with the ladder correction and focus algorithm in the projection brings a new head screen correction and achieves the screen real-time calibration.

It is worth mentioning that Hisense vidda, which is also firmly committed to trichromatic laser technology, also opened an open day of tricolor laser technology with the theme of "Laoshan on Sword" on the morning of the 9th. Like nuts, vidda also firmly believes that tricolor laser is the future of high-end projection.

This afternoon, Nuts also issued an open letter in response to the projector "standoff", in which nuts called for more healthy competition, and that products and technologies should not be exaggerated or maliciously smeared.

The purpose of this public blind test of picture quality is not only to prove the advantages of MALC eye krypton trichromatic laser technology, but also to promote the development of the industry and accelerate the upgrading of product experience through technical discussion. At the same time, Nuts sincerely hope that there will be rational competition among their peers, focusing on improving product technology, quality and consumer experience, so as to make continuous breakthroughs in projection picture quality and achieve global leadership in Chinese projection optics.
