Is there a "laser" on the laser?
Laser display, laser television, laser projection: There are many terms for laser in the big screen industry. It seems that as long as it is "I have a laser," then "my product is top-level, advanced, innovative and represents the future." On some occasions, lasers have become the concept of "best for everything," "representing everything," and "crediting everything." Once people say that "laser is just a light source" such "big truth", they will be attacked by groups.
"Only speaking lasers do not speak projections and talk about lasers." This phenomenon seriously ignores the nature of laser display. On the one hand, we must recognize the characteristics of the laser: solid state, highlighting, high color expression, high manageability, digital light sources, and so on. But on the other hand, it is more necessary to specify the laser display or projection. Its advantages and disadvantages all come from the projection display technology. If you leave the projection and talk about the laser display, you will fall into the trap of no more wood and you will not see the full picture of the laser display.
As a stage in the evolution of projection technology, the specific change in the laser display is the replacement of the projected light source. This change is partial. Although it has a huge change in the performance of the final projector, the core of traditional projections: optics, electronics, light valves, digital signals, color perception, environmental engineering, and so on have no "technology devaluation."
Even the special requirements of laser light source in terms of hermeticity, heat dissipation, etc.; the digitally manageable nature of the laser light source; and the projector's internal environment control engineering technology, projector intelligent performance compensation technology, color processing technology, and power management technology. In other areas, higher and better quality demand has been created.
Someone has put forward such an assumption: The best laser light source, coupled with the worst other projection accessories, it will be "rich rich"? The answer is self-evident. In fact, good horses must not only be equipped with saddles, but also good horses must be equipped with heroes and good horses to see Bole, which means that a good projection and good laser projection is a complicated system project. The laser may be a "barrel longboard" in today's projection technology, but the amount of water in the bucket is determined by the "short board."
In this regard, the global projection giant NEC clearly puts forward the concept of “LASER+â€, emphasizing that only lasers cannot achieve first-class projection displays. Laser technology must be combined with traditional projection technologies in depth. At the same time, lasers must also be based on their particularity versus traditional projection technologies. The relevant part of the development of innovation, in order to achieve a "true next-generation laser display projector." - Electric cars do not equal batteries, laser projectors do not equal lasers.
Good laser four elements, "+" out of the range
As a new generation of semiconductor cold light source technology, for laser recognition, many people stay on the visual characteristics of highlights, high colors and so on. However, in addition, laser light sources have many unique features.
For example, a laser light source is an array of laser diodes. This structure is inherently implantable: "temperature control," which relies on advanced power supply drivers, "hot exchange rate" design from the laser diode package level, includes Module encapsulation, array integration, fiber-optic integration and overall encapsulation, “seal and dustproof†characteristics, numerous “sensorâ€-aware designs inside and outside the array light source, and stable “controllability†of the color temperature of the semiconductor light source in brightness adjustment, and products The predictability of the change of the performance curve over the lifetime is matched with the "algorithm" and so on. The uniqueness of these laser sources is the space where LASER+ is learning.
Focusing on the "deep" characteristics of these laser sources and the projection industry's own development laws, NEC has pioneered "selection of light sources," "seal heat dissipation," "control algorithms," and "4K+ image quality," and four high-quality lasers. The golden standard of projection.
Among them, light source selection technology, not only "select light source", but also includes integrated design, carrier material selection, thermal efficiency experiments, drive device selection, light source body consistency point-by-point perception and control system selection, built-in sensor selection and design, etc. A lot of content. This is already a complex project involving several electronic and material categories and several on-site inspection experiments.
The second point, "seal heat dissipation" is actually a conventional topic of projection display. However, laser products are more sensitive to the accumulation of dust and uneven heat transfer than traditional mercury lamp products. It can even be said that sealing the heat is the "life of the laser." This area has both material and engineering challenges, as well as long-term industry accumulation and thermal fluid mechanics research and experimental difficulties. Only by overcoming these technical difficulties can we achieve a laser projection that is stable, brilliant, long-term, reliable, and has the expected life and effect.
The third aspect is "algorithm control." The brightness of the laser source, the brightness of each laser diode in a light source body is controllable. Not only the working state is controllable, but also the work can be instantaneously controlled and the consistency in long-term work can be controlled. If combined with other sensor data such as temperature, system performance curve obtained by long-term engineering experiments, and high reliability non-polar adjustable power supply driving system, laser light source can achieve effect adjustment under manual intervention and intelligent self changing with working conditions at any time. Adjustment to ensure that the entire product throughout the life of the performance is highly stable.
And "algorithm control" is not just a matter of the light source, he is also the protection of the entire projector environment, that is, through the hardware driver, sensor data, real-time protection of the entire projector inside the good working conditions. At the same time, "algorithm control" is also the patron saint of projector display effects, including white balance automatic adjustment, color temperature fixing technology, brightness uniformity technology, color balance control and so on, constituting a hardware, input signal, and application period device performance. Complex "dynamic processes" including curves and built-in sensors.
On the whole, "algorithm control" is a result of hardware support, software implementation, long-term engineering experience and knowledge integration, and is a core component of intelligent projection light sources and stable and reliable projection effects.
The fourth aspect, “4K+ quality,†is simple and easy to understand. However, it is not easy to realize it. Including light valve upgrade, light valve drive upgrade, signal processor upgrade, high-definition optical lens upgrades, and further optimization of the focus system, involving ultra-high definition decoding, 120HZ drive, HDR function and drive, WCG ultra-wide color gamut, etc. In many areas... 4K+ image quality is basically a comprehensive "big shake-up" and "great evolution" of the core components of the projector other than the light source.
Through the above introduction, it can be seen that a good laser projection is not simple: it includes many high-tech and knowledge, but must also have long-term engineering research experience and innovation accumulation. For such a "good" product, laser is just a beginning, and the work after that is even more "high-end." This is like the best scalpel. If you throw a scrap of iron on the street, but in the hands of a good doctor, it is the lives of millions of people. To build a high-end laser projection requires not only a "good scalpel" but also a "good doctor" like NEC.
The laser shows go to the key intersection, "true" laser Biffy
2017 is a very critical year for the laser display industry. The domestic market is expected to have an annual scale of 253-30,000, which will be twice the total sales volume of laser projections.
In such a critical period of industrial development, the laser industry particularly needs the spirit of “more truthâ€, and it is particularly necessary to make clear what the “true†laser display is: to abandon the laser omnipotence theory and return to the “new light source + old projector + continuous innovation†of laser projection. "The nature of the industry, return to the basis of comprehensive technical standards to determine the product quality of the "balanced value system."
"Retrospective Qingyuan": This is not only the responsibility of the industry enterprises themselves, but also the natural law of the development of the industry. Industry sources pointed out that with the increase in sales volume of laser projections and consumers’ maturity in product recognition, what exactly laser display is and what kind of product is a good product issue will naturally form a “standard†in the minds of consumers and market customers. "answer. The act of bluffing the market by relying on a momentary boasting and simple concept will surely make the original appearance.
It is at this crucial stage of industrial development that as the earliest supporter of the laser industry, the global projection giant NEC has particularly emphasized that laser projection needs “return projectionâ€, “return to technical detailsâ€, “return to technological innovation†and leave the concept war. To achieve value. It is believed that under the impetus of many enterprises in the industry and in the evolution of the industry's own laws, the era of a "real" laser is bound to come.
