The inability to watch at close range for a long time has caused many audio-visual enthusiasts who have the pursuit but have no choice but to be limited by the depth of the living room to stop in front of the 60-inch LCD screen.
Could it be that you can’t have your cake and eat it too? In May 2014, Guangfeng Huaying launched a living room cinema-level laser TV. With its 100-inch radiation-free and non-radiation It hurts the eyes and leaves the screen cold, quickly igniting consumers’ desire to buy. The huge market potential has also attracted many imitators who want to share the market share in this new continent. If you search for keywords such as "laser TV" and "100-inch giant screen" on the Internet, a series of merchants with different prices and brands will appear. There are so-called cutting-edge businesses and some who claim to be industry veterans, but without exception, they all hold up " The brand “100-inch giant screen that doesn’t hurt your eyes” really confuses consumers.
So, what is the difference between this seemingly simple TV screen?
Both are ultra-thin cold screens: the "face" is very different
Looking around, most of the brands of laser TVs on the market today are labeled as "ultra-thin cold screen." What exactly is a cold screen? Song Wanxu, the technical manager of Guangfeng Laser TV, said: "The cold screen refers to the cold screen during work. , the screen does not generate temperature and does not need to be powered on, thus reducing radiation damage to the eyes, and it is also more energy-saving and environmentally friendly. "
The overall thickness of the cold screen used in Guangfeng Laser TV is only 1 cm." "Ultra-thin" is certainly true. So, compared with the so-called giant-screen laser TVs of many other manufacturers that also use the "ultra-thin cold screen" sign, what is the difference between Guangfeng's laser TV cold screen?
We have studied several media In the evaluation report of Guangfeng’s cinema-level 100-inch giant-screen laser TV in the living room, Guangfeng is very different from other manufacturers in terms of the manufacturing process of the screen. Let’s talk about the most intuitive surface layer first. The flatness of the screen surface layer of Optical Peak is required to be less than 0.5%. Compared with conventional display screen parameters, this standard is almost harsh; secondly, its accuracy standard reaches 0.07mm2, which is the highest level A-level screen. Even scratches like hairlines can still be detected and will not be missed. What needs to be emphasized is that the screen of this masterpiece was jointly developed and manufactured by the world's top companies from four countries: South Korea, the United States, Japan, and China. It uses a nickel-plated aluminum frame specially tailored for laser cinemas. It is low-key and luxurious and has a long service life. improve. On the other hand, for counterfeit products that also claim to have "ultra-thin cold screens", because the surface film layer of these manufacturers' non-exclusive screens does not fit well, they will warp after being used for a long time, and the frames of almost all counterfeit products are made of aluminum plates. , it is packaged and sold after simple pressing, the rough edges are directly visible, and it is very easy to deform over time. In contrast, judge from superior to superior.
The difference is not just about 5-layer and 6-layer: there is a saying "inside"
Careful consumers can easily find that the product promotional materials of many brands of laser TVs often appear similar to " "DNP screen bottom layer", "screen built-in optical technology"... and other terms, but most of them are mentioned in one sentence without any emphasis, which makes people feel that they only vaguely pose a high-level posture, but cannot see the real meaning. Mode.
As we all know, DNP is the world's largest supplier of optical screens. As early as a few years ago, Guangfeng Huaying signed a contract with DNP, and DNP provided global customized optical screens for Guangfeng, with screen parameters that are unique to the world. In terms of screen structure, most laser TV screens have 5 layers, while Guangfeng Laser TV uses a unique 6-layer ultra-microstructure ALF Xuanwu bionic cold screen, which has a more optimized structure. The screen is not powered and has no radiation. 100% of the imaging comes from the reflected light of the screen. It can be viewed easily and comfortably with a viewing distance of 4 meters. The overall effect is far superior to various imitation products on the market.
The fundamental reason why Guangfeng’s global custom-made optical screen completely outperforms ordinary DNP screens is that there is a big article in the bottom screen. It is reported that the bottom layer of Guangfeng's screen is directly customized by DNP American laboratory. The material is vacuum aluminum plating film and aviation-grade honeycomb aluminum material, using semiconductor vacuum technology. Obviously, imitation products are much inferior in this regard: the bottom layers of the cold screens of these follow-up manufacturers are mostly made in China or DNP Japanese production lines, and the equipment is very different. In addition, because it is not an exclusive screen supplier, the bottom layer provided by DNP to other brands is an aluminum powder glue layer, which is not dense enough, has low grayscale, poor production technology, and small screen gain.
Inner wisdom makes the display effect very different.
Exclusive customization, both internal and external. Perhaps these "behind-the-scenes secrets" do not need to be known by end consumers. However, the strict production process and precise manufacturing technology finally present to everyone the real visual difference. A set of authentically verified data can explain it all: the gray scale of the screen of Guangfeng Laser TV is 40% higher than that of ordinary screens, and the screen contrast reaches 200% of that of imitation and unauthorized products. The most intuitive feeling is that the color performance is excellent and the picture levels are richer. The most impressive thing is that the Fresnel lens of the Guangfeng laser cold screen can directionally reflect effective light; the absorption layer reduces ambient light, which also allows the audience to easily watch various special effects blockbusters and exciting sports under normal indoor light. tournament.
After various comparisons, it is easy to see that with the same 100-inch optical cold screen, laser TVs of various brands are mixed, making consumers who are interested in choosing a high-quality product confused. The only way is to buy more. Look at Dobby. As the leader of domestic laser TVs, the 100-inch laser TV launched by Guangfeng Huaying has undoubtedly gained the upper hand in this competition. It is conceivable that in the days to come, this tall and giant-screen laser TV will also perform better in the market.
