On May 10, at the new flagship intelligent projection conference, including JIMI RS Pro 3, 100-inch soft light art TV, XGIMI MATE JIMI projection supporting solutions and other products were all unveiled. However, the most impressive thing is that this time it is not a single product, but two new technologies across the era of JIMI Dual Light super mixed light and Hawkeye hardware-level computational optics.
In particular, Dual Light super mixing technology, in addition to LED light source, monochromatic laser light source, and three-color laser light source, opens up the "fourth pole of projection light source", and "re-empowers" the future of intelligent projection with unprecedented innovation, which can be called a new breakthrough of "stone breaking".
Why did JIMI open the "era of third-generation projection light source technology"?
Projection display equipment is essentially a "light" processing system. The quality of its image depends first and foremost on the quality of the "light source" at the source. In the history of projectors, there have been a variety of differentiated light source attempts, such as early mercury lamps, xenon lamps, etc., the current mainstream LED, monochrome lasers, and other brands in the market have anchored the "three-color" laser light source.
Many light source solutions are active in the market, and from a certain angle it has been shown that these light source technologies are "not perfect", that is, they have significant defects: in this regard, although LED light sources are naturally three primary color displays, color comfort, spectral continuity, close to sunlight, is a solid-state long-term light source; However, it encountered a bottleneck in further improving the brightness; Monochrome laser light source, the biggest advantage is that it can achieve ultra-high brightness at low cost, even up to 100,000 lumens, but its defects are as prominent as the advantages, that is, monochrome laser imaging brings weak color ability, picture quality comfort is general, for home and other scenes that emphasize more film and television applications, this is a relatively large hard injury; As for the early mercury lamps and xenon lamps, because of their life problems, they have already entered the elimination sequence.
In addition, the three-color laser light source meets the needs of high brightness, and also has the theoretical ability to improve the color effect, color gamut coverage and color accuracy expression, and its future cost can be reduced is also very large. This is also the reason why many manufacturers are enthusiastic about three-color laser technology.
However, in Jimi's view, as a potential stock in the industry, three-color laser also has natural defects - this defect is the same as its color advantage: that is, under the high purity of the laser, the wavelength is too concentrated, the frequency is too single, resulting in imaging speckles, imaging edge rainbows, image quality supersaturation, lack of comfort under the continuous characteristics of natural light wavelengths.
Because the strongest advantage and the biggest problem come from the same reason, the overcoming of its disadvantages by the three-color laser has always been a "pain point and bottleneck". Jimi pointed out that even today's speckle suppression technology, which reaches 96%, is still "visible to the naked eye" under home conditions and limited viewing distance, which significantly affects the freshness and resolution of image quality. Because speckles can only be "weakened" at best, not "eliminated". Therefore, the three-color laser is not an ideal intelligent projection light source from the current point of view.
Zhong Bo, chairman of Jimi Technology, said that Jimi has been deeply cultivating the projection market for many years, and Jimi has almost carefully "dug deep" into the above various solid-state light source technologies, from LED light sources, monochromatic lasers, two-color lasers and three-color lasers, but it is because of the process of doing these light sources carefully found that they are "not perfect"!
So, in addition to these "paths" mentioned above, are there any new solutions and technologies that can make the power of "light" "perfectly" present on projection products? This is the problem that Jimi Dual Light super mixing technology aims to solve.
Zhong Bo believes that the laser and LED light source are combined into one, and the LED short board is made up for with a pure red laser, and the ultra-high color gamut and ultra-high brightness are brought by the improvement of the red color gamut and the gain of laser brightness; Use full-color LEDs to make up for the short board of lasers, so that the natural spectrum is not tired for a long time. Two completely different light sources, unprecedented peaks collide, truly achieving an excellent viewing experience of super comfort, ultra-high brightness, ultra-high color gamut, and ultra-high color accuracy.
At the same time, Zhong Bo pointed out that Dual Light super mixing technology is not a simple technical upgrade and breakthrough, but is expected to break the technical bottleneck of a single solid-state light source and open the era of third-generation projection light source technology.
In terms of Jimi, the light sources used in traditional commercial projection (mercury lamps, xenon lamps, etc.) are divided into the first generation of light sources, while solid-state light source LEDs, monochromatic lasers, three-color lasers, etc. are the second generation. From the current point of view, these two generations of technology have obvious shortcomings, either brightness will reach the bottleneck or the color is not good, or it is speckles, color edge such as the disadvantage of viewing discomfort, and Dual Light super mixing technology takes into account the brightness, color, color accuracy and other core indicators of projection to achieve the most effective balance, so it will be an epoch-making technology lead, so Jimi defines it as the third generation of light source!
Dual Light super mixing technology, "ceiling" style innovation
JIMI's new Dual Light super mixing technology is the "third generation of light source" in the current intelligent projection market. As a new technical route, it fully explores the full color and experience comfort value of LED light source, and the color and accuracy value of laser light source, and organically combines the two to achieve a comprehensive product experience breakthrough.
Jimi Dual Light adopts a new five-channel laser LED hybrid optical path design, which realizes the perfect combination of the two light sources through the ingenious placement of the light source position and the recombination of optical materials.
The system uses newly developed LED and laser semiconductor light source devices, combining 2 completely different light sources and 6 very different light bands through 278 new patented technologies. It has realized the natural spectrum display technology of ultra-high color gamut, ultra-high brightness and ultra-high color accuracy - Dual Light super mixing technology.
In particular, the continuous wavelength characteristics of the LED light source and the unique multi-wavelength hybrid laser system of Jimi have successfully achieved a very high product experience without speckles beyond the perceptible limit of the naked eye, laying a solid foundation for ultra-high color gamut, color accuracy, and high brightness intelligent projectors to break through the historical bottleneck of picture quality.
Tang Legend, product director of JIMI Technology, said that JIMI Dual Light super light mixing is completely different from traditional light mixing "underlying technical architecture". Because, this time, Jimi pure color laser and full-color LED light source achieve organic combination. In particular, the optical path design is to achieve 5 channels of mixed luminescence, and these 5 channels are not simple and direct mixing, of which there are two red, two green and one blue light between each channel optical path to ensure the mixing of pixels and pixel homogeneity, while ensuring that each optical path eventually appears color accuracy, optical path control, etc., these are very high technical challenges.
In order to effectively achieve the perfect integration of these five lights, the entire optical team of JIMI has achieved "subversive breakthroughs" in multiple technical links such as the bottom layer of technology, material selection, and optical path design, so as to ensure that this time brings such a good super mixing technology innovation.
Xiao Shi, CEO of JIMI Technology, said that the "birth" of Dual Light is the most successful "technology crystallization" of JIMI in many years in the innovation and R&D strength and adoption of the "vertical integration" strategy. The horizontal is from R&D, design, production, sales and service to end-to-end full-link closed-loop; Vertical is a full-link closed-loop that realizes design innovation and production of projection core components within the enterprise.
The starting point of most manufacturers to do projection is the assembly of the whole machine, and Jimi starts from the very source and starts from the lens. It is such a technical "excellence" that has created the "birth" of the third generation of light sources.
At the press conference, JIMI's new flagship models RS Pro 3 and 100-inch soft light art TV MIRA both adopted super mixed light technology to achieve a breakthrough in display effects. Among them, the brightness of RS Pro 3 reaches 2000CCB lumens, which is nearly half higher than the previous generation of products, and the color accuracy standard has also reached the high standard of △E≈1. In this regard, Jimi particularly emphasized that CCB lumen's brightness is the industry's current high rigor brightness standard that truly meets the high rigor of home movie applications, and the product completely adopts the average real standard; The color accuracy data of Jimige is also derived from the measured average value of mass-produced products.
CCB lumens and the traditional brightness indicators used by many projectors in the industry, and even the new CVIA standard, fully take care of different manufacturers with "huge differences in technical level", and allow a wider range of measurement conditions, allow mass production product parameter deviation value of up to 20%, etc., and the parameters are not rigorous. Especially in the concept of color accuracy, the high color accuracy of many products is the "limit" data, that is, the "highest value" obtained by a specific product after specific laboratory, specific conditions, and specific debugging, which cannot be mass-produced. The performance advantages of JIMI Super Mixing Technology enable JIMI RS Pro 3 to achieve the high standard of △E≈1 mass production color accuracy.
The 100-inch soft light art TV MIRA is the crystallization of three new technologies, including Jimi super light mixing, self-developed ultra-short focus optical path design, and customized 2.2 times high-gain anti-light screen. Its brightness can be reached, the brightness of the 100-inch screen is 66.7fL, (fL Ford Lambo is the display unit of the brightness of the domestic cinema line, and the brightness standard range when playing 2D movies on the domestic cinema 100-inch screen is 14fL~20fL); Especially during the day, its suppression of ambient light is as high as 97%, which truly brings a "color TV" experience effect.
Starting from the light source, the "experience" and "mass production performance" of JIMI's new generation products have broken the existing product experience ceiling in the industry. This is another milestone in the history of intelligent projection.
Perhaps based on the "confidence" of Jimi Super Mix, Zhong Bo mentioned the slogan of the upcoming comprehensive "benchmarking" TV after 7 years. And this time in Jimi's view, challenging TV has become more likely.
Hawkeye hardware-level computational optics makes projection debug conversions "hard"
At the press conference on May 10, Jimi also came up with another transcendent innovative weapon, namely: Hawkeye hardware-level computational optics. This innovation places special emphasis on the "projection light processing, the debugging and conversion of the final light part" into the "hardware" era.
What is hardware optical computing? In contrast, it emphasizes the traditional intelligent projection optical calculation, which is mostly implemented in "software": for example, screen scaling and zoom are completed by the digital processor behind the 1.2:1 fixed focal length lens, which is completed by the abandonment of resolution; Many applications, such as keystone correction and side projection, are also completed by software calculations at the expense of resolution and brightness.
Therefore, if consumers want to achieve the "best" product image quality, they must find a more suitable projection distance, projection height, and projection angle, which greatly hinders the convenience and diversity of product applications. JIMI Hawkeye hardware-level computational optics is to solve this problem.
Eagle-Eye hardware-level computational optics 30,000 yuan professional engineering projection technology decentralization
It is reported that the hardware-level optical calculation applied to the JIMI RS Pro 3 mainly includes three parts of innovation: first, the cat's eye bionic dynamic aperture, which can adjust the brightness and contrast of the picture without loss; Secondly, the dynamic spectrum module can adjust the color range of the picture through the dynamic filter to further improve the color accuracy; Finally, the newly designed automatic optical zoom module can control the screen zoom more precisely, bringing lossless picture adjustment capabilities. Relying on the three major optical hardware, JIMI realizes hardware-level control and mutual conversion of brightness, contrast and color, screen scaling, brightness adjustment, keystone change, no longer need to sacrifice image quality and resolution, and truly present native 4K picture quality to the audience anytime, anywhere.
At the same time, Jimi, a system composed of hardware-level optics, is also an intelligent real-time change precision system. That is, Hawkeye hardware-level computational optics intelligently schedules these optical hardware based on the perception capabilities of Hawkeye visual perception system (including CMOS + single-point TOF, ambient brightness sensor, AI algorithm and user scene data, etc.), so as to realize real-time adjustment of brightness, contrast, and color. This will allow consumers to really get, brighter during the day and brighter TV watching; Enhance the color at night and watch movies more immersively; Optical hardware adaptation, all-weather "senseless, automatic" good picture quality excellent experience.
Hardware-level precision optical equipment and intelligent driving process allow the projection to be converted and debugged to truly harden in the "picture quality" dimension. This is a new breakthrough in the industry brought by JIMI Hawkeye hardware-level computational optics, and it is also a new dimension of the performance of traditional intelligent projection optical systems.
With continuous innovation, Jimi must be the perfect "chaser of light"
Light is the soul of projection display, and chasing light is the soul of projection innovators. With two new technologies of Dual Light super mixed light and Hawkeye hardware-level computational optics, JIMI once again interprets the masterpiece of projection innovation:
At present, domestic audiovisual consumption is accelerating to large-screen and high-quality development. The projection industry, especially the home market for ordinary consumers, constantly calls for and pursues higher-end display performance - this is not even related to the price of the product, from thousands of yuan machines to tens of thousands of yuan products, and even more expensive products, are constantly pursuing a more extreme performance experience.
Whoever can continuously break the ceiling of the industry in terms of performance experience will take the lead in the future competition point. The two core innovations of JIMI, mixed light source and hardware-level computational optics, comprehensively break the performance limit of traditional intelligent projection and bring new possibilities for product applications. This is also what the JIMI brand has been doing in the past decade: it is the innovation along the way that has made JIMI from a fledgling to the fifth consecutive championship in the domestic projection market and is accelerating its entry into the global market.
According to JIMI's 2022 financial report, its R&D expenses are 377 million yuan, and the R&D revenue ratio is as high as 8.93%. In this year, JIMI once again obtained 72 hardcore invention patents (non-new application or appearance patents), which fully reflects JIMI's rich innovation achievements and scientific and technological innovation hard verification power. In particular, the R&D expenditure of 377 million yuan far exceeds that of peers. It is also under this persistence that JIMI continues to break industry practices and ceilings, open up new technological paths, and achieve leapfrog innovation.
"Jimi to chase the light, let others chase Jimi"! This is the signal that JIMI's new press conference on May 10, 2023 brings to the industry. JIMI RS Pro 3 became the world's first 4K home telephoto projection that supports Dolby Vision, and was officially awarded the world's first professional color accuracy Performance Tested Mark certification by SGC. Under the new competitive dimension of Dual Light super mixed light and Hawkeye hardware-level computational optics, JIMI has "immediately crossed the knife", waiting for peers in the circle to take on.
