Quantum dots are alien technology? Buy black electricity do not be fooled by these concepts

â–  Black home appliances are home appliances have moisture
In the previous issue, the author performed a 360° hybrid shredding on the white goods billboards in home appliances, and wrung out a lot of good-looking but water-intensive appliance technologies. Maybe many of my friends have not seen fun. This time, Bingzhuo engaged in the first-to-be-stowed work attitude. I decided to tear off the "thinking formula" that belongs to black power.

Although most computers are inseparable from black, they are not really black
As the name implies, black battery is generally designed as a black appliance. It is generally applicable to non-living entertainment devices such as TVs, players, game consoles, and audio systems that require a good heat dissipation environment. Some enthusiasts say that I use computers all day long. Marketing that can not fool me, then you can still say too young, do not swindle you deaf and then smash wallets, black manufacturers come dozens of billions of profits on the year (of course SLR One of the three legends of Sony is not in this list.) Selling computers can't earn so much money!
Don't know this cognac use? You can't use it after all right anyway
Take the television, today's TV is not the same high-tech communication equipment that had an antenna and a built-in demodulator. The coaxial interface behind the TV is a dispensable tool to meet the standards of the Ministry of Industry and Information Technology. You are either connected to the HD set-top box and then transferred to the TV, or there is only a network TV box, tall users may be Blu-ray player + home theater audio, but in any case, now the TV is used in the display, everyone Comparing the display market, where prices and technology have long been razor-sharpened, let's look at the TV and you can understand something.
High quality internet video payment is essential
Of course, as entertainment content consumption becomes more and more the mainstream of information consumption, the black consumer products as a content consumer terminal are also developing in the direction of hardware margins or even negative profits and quick sales. The ultimate direction is still to stimulate users' content consumption. Therefore, how to scientifically select the software that is installed on the black power products does not sink deep into the bottomlessness of membership/packages, and it also becomes the key to reducing the late-stage cost of black-box procurement for users.
Young people should never touch these strange boxes with pipes

The author will focus on television and its peripheral entertainment equipment for discussion. Some friends will say that black power also includes speakers. This is what you can say about it... Members, for the author of this kind of buying headphones wireless In the case of fungus above all, the low quantifiable content of audio is equal to metaphysics. I really can't hear why. Regarding hydropower on the Yarlung Tsangpo River, what you say is right, let's go.... ..

â–  Quantum dots, curved screen, MEMC is black technology?

At present, when it comes to television novelty technology, quantum dots are the first to bear the brunt. Since quantum dot materials have a very narrow emission spectrum and can achieve high-purity color display, they have high hopes in solving the inherent defects of traditional LCD TVs such as low color gamut narrow contrast. . The mainstream TV manufacturers are all using quantum dots as their high-end product publicity gimmicks, and even launching concepts such as QLEDs to counter OLED technology, but we must remember that whether it is QDs or QLEDs, they are actually solving LCD TVs. The backlight problem is still essentially an LCD TV.

Quantum dot improvements are still just LCD TV backlighting
Actually, the adoption of quantum dot backlight technology is far earlier than the hype of its concept. As early as CES 2015, the TRILUMINOS Terry charm technology displayed by Sony actually replaced the yellow phosphor powder with quantum dots on the basis of traditional W-LED backlighting. Perhaps Sony did not feel that this technology was so revolutionary in its display effect. Therefore, it chose to muffle, but it did not make a big fortune. On the contrary, many "later" manufacturers rely on quantum dots to earn pity.
Sony is worthy of praise for its new technology
Despite the high color gamut and thinness of TVs, quantum dots still cannot solve the inherent material defects such as the dark black of the LCD and the slow response time. Some friends will ask, since the quantum dots can achieve a variety of high purity. Color, and life expectancy is much higher than the organic OLED light-emitting point, can't it make self-luminous structure similar to OLED screen? In fact, the answer is yes. The domestic panel maker BOE announced last month that it has developed the world's first active quantum dot light emitting display (AMQLED). However, it is only 5 inches in size. The mobile phone is also available for use. The TV wants to use it. Some waited.
Most of the movie screens have no curved surfaces. Do you feel unnatural?
Another high-end TV market technology that looks very ridiculous is the curved screen, which claims that any distance from the screen to your eyes is equal and the screen is not deformed. In fact, you only have to sit in the middle of the "Emperor" to achieve this effect, so that the television as a person's theater is also somewhat off the meaning of a family entertainment center, and who cares or can see two or three meters away from the TV With a few centimeters of visual distance difference with you? In fact, the realization of curved screen is not as difficult as everyone imagined, in addition to being able to achieve a flexible OLED, the LCD surface of the market is a direct bending plane The panel, just pressed to the limit of the glass cover does not break, in addition to reducing some of the yield, there really is no cost increase.
3D TV technology that was killed by alive
Because the effect is not so intuitive, the “black technology” in television software is being hyped by manufacturers. MEMC, that is, motion estimation and compensation is a high-end TV “must have” technology widely recognized by many manufacturers and consumers. Speaking of MEMC, we must mention the shutter-type 3D technology that has disappeared in the mainstream TV products. Their common technical features are the need for screen refresh rate of 120Hz or more, and 3D is to play the left and right eyes separately every two frames. MEMC inserts a black frame in the middle of two frames to eliminate the residual of human vision. Therefore, in order to ensure a halving frame rate of 60 Fps, the TV refresh rate must be higher than 120 Hz. However, we found that many mid-end 4000-10000 yuan products also have MEMC technology, but the screen refresh rate is only 60Hz, so that half the visual frame rate is only 30Fps, smear is indeed reduced more, but my eyes are also Flashing!

â–  foreign brands must be better?

Although according to statistics, in 2016 China's color TV brand shipments accounted for more than 30% of the global market share, and domestic brands including traditional brands and Internet brands had a total of more than 85% of domestic brand activity, it was in the minds of high-end color TV consumers. The products still seem to belong to foreign brands. Even if the sales of foreign brands have been constrained by domestic brands in recent years, during the 51 promotion period this year, foreign brands have increased their shares by 4% and 5% respectively online and offline. Counterattack, reflecting the tenacious vitality.

The market position of independent brands is not stable
It must be said that the favor of Chinese consumers is not a matter of moment. Foreign brands have left a very profound and outstanding impression on Chinese consumers in terms of panel technology, color management and high-end product quality, such as South Korea, which is still leading OLED technology. Manufacturers, domestic manufacturers want to manufacture OLED TVs must buy screens from LGD, Samsung OLED screens only supply their own products, and Sony is proud of the color management technology, not only the adjustment of software algorithms, but also will carry professional Color management chip. However, in the era of television intelligence, domestic newcomers represented by Internet brands have obvious advantages in TV operating systems. They not only use marketing models to further reduce the price of TV products, but also lead the entire Chinese color TV industry to foreign brands. Hinterland - shows the overall development of core technology.
The domestic panel factory's production line is progressing to the world's most advanced level
Borrow a famous saying in the industry: buy TV is to buy that piece of screen! In the final analysis, TV is still a monitor. The cost of the screen occupies a large part of the TV's selling price. However, China’s inability to produce mainstream mid-to-high-end LCD panels has caused TV manufacturers to be controlled by foreign manufacturers. Even foreign companies have taken early measures. The quasi-adjusted schools are biased toward Mars' so-called colorful liquid crystals to flicker consumers. Domestic manufacturers can only hope to sigh. Old-fashioned practical low-end screens that are on the verge of elimination are fighting the so-called “cost-effectiveness”. However, with the rise of independent panel makers such as BOE and Huaxing Optoelectronics, domestic TV manufacturers have gradually started to take a slice in the high-end market. Many products of foreign brands have also adopted panels from domestic manufacturers, so that there is no screen production capacity. The internet brands are also constantly emphasizing the screen's foreign "descent." BOE, which specializes in "black technology," has even launched the world's leading high-resolution giant screen at trade shows. This has laid a solid foundation for domestic brands to further enter the high-end market.
The world's first 10K panel was born in BOE
As a large-screen display, after solving the problem of backward core technologies such as the panel, the advantages of domestic brand TV in software are even more obvious. It inherits from the Android system's relatively “open” Android system customization environment, whether it is from Network source or system ease of use has far exceeded foreign brands. Internet brands have even created split TVs, and TVs have returned to purely "screen" functions, making boxes more powerful and allowing TV home durable goods to transform into digital consumer goods.
The acquisition is not a technology but a market
Having money to buy Sony, no money to buy XX, if not XX manufacturers marketing routines, is the display of home appliance abuse. Here we do not discuss trade protection or the issue of national honour. From the point of view of technological maturity alone, domestic manufacturers of black-box products do not have as many product lines as white goods. The growth is also due to the fact that the cost brought by the technological upgrading of the self-sufficiency panel maker has been reduced, and the true overall oversight is still a long way to go, but at least the mid- to low-end prices have already achieved a victory for foreign brands. On the other hand, if you simply want to buy foreign-branded TVs, you need to know that some brands, especially those sold in the Chinese market, have had little to do with foreign brands, such as Sharp’s for Foxconn, Sanyo’s for Hisense, etc. You have to be careful!
â–  Is there enough network box?
I have already explained clearly in front of the fact that TV is currently a large-screen display for ordinary users, then a monitor must have a host. For TV watching, the previous host was a cable set-top box, and now it is a network box. . Of course, many smart TVs are equivalent to having a built-in network box. Even if the built-in box can be upgraded through the use of an external host or card, the TV is bound to be more expensive. But is the web box really a substitute for everything?

The internet box has evolved to become part of the organic expansion of television
The basic function of TV is still live broadcasting. This basic function that was built in the early days of the Internet box was cut off mercilessly by broadcast and television, leaving behind the disputes with the local cable companies, saying that the quality and richness of live TV broadcasts. In fact, there is still a considerable distance between the network box and the HD cable set-top box. Even if a third-party broadcast app is installed, there is no HD channel, and even the SDTV program quality is far worse than the cable. Delay and Caton make you doubt the life. Not to mention that the webcast is often interfered with by copyright. During the Europa League last year, the author used the third-party TV app to watch the live broadcast of the game. Before the game, the CCTV5 ad was very normal. Once the game started, the signal was cut off immediately. This bitterness. Presumably many people have experienced ···
The large capacity of Blu-ray Disc 50G-100G determines the extremely high quality of the source
When it comes to image quality, you have to mention the disc resources. With the development of the current paid network video resources, either watching movies or going to the cinema's "compatible" mode to meet the needs of the vast majority of ordinary users, Blu-ray discs and players The high price makes it a small number of enthusiasts' playthings. But don't forget that the vast majority of people's home TVs are not prepared for online video, even if it is nominally 1080p or even 2K, 4K network video, the bit rate will reach the standard of wired high-definition, distance from the real Blu-ray 1080p is also separated by a YouTube 4K, not to mention the 4K HDR source that Blu-ray Disc has already fully turned to, so you are watching the low quality of the large areas of color patches and edge glitches compressed by the H.264 algorithm. The video reminds you that your 4K TV hardware resources are being seriously wasted.
Despite the host logo, the core is modified from our common APU
As for the Blu-ray player, I think many of my friends will think of the game console. Yes, the XBOX and PS series are not only contemporary game artifacts that are far more efficient than PCs, but also a cheap multi-function disc player. Of course, the game console is also The “hard-hit areas” in which user content is consumed are not only financially burdensome, but also consume hundreds of dollars in physical games and movie discs. The entire consumption form also lags far behind the development of the Internet. However, with the emergence of desktop OS game consoles such as Steam and Tencent TGP Box, not only the richness of content consumption has been greatly improved, but also the operational efficiency of the game has moved closer to the host. On the other hand, the XBOX One will also support mouse and keyboard operations in the near future. It is also a general trend for game consoles to play the full potential of their PC hardware. It may be that we have not waited for everyone to compete on the host or the PC. The integration of the people has already been unavoidable.
Xiaomi’s external wired high-definition CAM reader was blocked at local radio and television companies
Regardless of how rich the video resources of the built-in systems promoted by TV manufacturers are, and how powerful the network box is, the TV entertainment system has developed to this day and is limited to extremely poor network bandwidth. It is still not possible to solve all problems with a single Android box. Although manufacturers such as Hisense, Sony, Skyworth, Xiaomi and others tried to solve the problem of wired high-definition integration with a built-in CAM reader, this is only the first step of the Long March, and this feature is not a prerequisite for success. Big manufacturers have abandoned one after another. So the root of the problem lies in the construction of network hardware technology facilities. If 100Mb and Gigabit fiber are popularized, if cable content providers are willing to modulate more quality resources to the Internet, we will probably be able to implement a remote control device. Dream it.
