To say that the CES exhibition of the two television sessions of 2016 and 2017, "4K ultra high-definition technology" is of course the core. There is no end to people's pursuit of picture quality. After they are no longer content with 1080p, it is only natural that everyone will turn their gaze to 4K.
The benefits of 4K ultra-high-definition technology needless to say, but that is far higher than the resolution of traditional 1080p, in terms of clarity can bring people a higher viewing experience. Although 4K content should be popularized, it will take a long time until it completely replaces 1080p. However, there are so many competitors, for fear that manufacturers who are behind others will not be quick enough.
Another technique that must be mentioned is HDR. HDR is hailed as “a really important technology in the 4K eraâ€, which can bring more contrast performance, more display details, and more vivid and rich color reproduction. If 4K resolution can only make the picture in your eyes more sharp than the original, HDR brings a new visual experience and instant improvement.
However, 4K and HDR are all standard, after all, everyone has. After this competition, everyone began to look for other selling points. Sony’s flagship TV has a built-in panel that relies on vibration, LG promotes its minimalist and ultra-thin, and Panasonic’s professional-grade experience, while Samsung begins to pick up the banner of QLED.
So where are the next-generation TV technologies that people are chasing and recognizing like 4K and HDR? If you say that this technology may be "brightness", would you believe it?
Bright war
Although people are still obsessed with the amazing changes brought about by the increase in resolution, Patrick Giffis, senior vice president of technology from Dolby, has called it a TV The competition that manufacturers are about to start next is the brightness of their battlefield. Whoever can bring a brighter display can be the winner.
The Ultra High Definition Alliance has set a standard that TV products must achieve a brightness of 1,000 nits to achieve their standards (1 nit is equivalent to the light that a candle can produce). However, Geoffs believes that such brightness is still not "perfect", and future manufacturers will continue to upgrade. "There is no doubt that the competition for Nit has already begun. The next competition will be 2000 nits. I don't think it will take a long time. 4000 nits of display devices will enter the consumer market." Said.
You may not think that the brightness of the TV is so high, or that the brightness of more than 1000 nits will not improve on display. But according to the technologist, the increase in brightness has a positive effect on the color rendering of the TV, making it richer and fuller.
why? In fact, white is composed of the highest brightness of its constituent colors. The higher the brightness of a blue pixel, the closer it gets to white. As a result, when the brightness of a white pixel is limited to 1000 nits, the brightness of blue and other colors will be limited, because when the latter's brightness gradually approaches this limit, they will begin Loss of original color, turning white. This means that the brighter the display, the better the color saturation of those colored pixels at high brightness.
Someone may have doubts: too bright TV screen will not make people can not stand it? The executive said that Dolby had already experimented, and the viewer could feel the change in perception brought by brightness within the limits of 10,000 nits - it was 10 times the standard set by the Ultra High Definition Alliance. Because of this, Dolby Vision, HDR's HDR standard, limits the brightness to 4000 nits.
Why not 8K?
Since people are so obsessed with resolution now, why wouldn't we continue to improve after 4K and continue to launch 8K resolution TV products? After all, incumbents such as Sharp and LG have all shown us 8K TVs.
But what we must understand is that a new resolution standard needs to be promoted, and it is not the TV manufacturers who have launched the product that will do it all. In addition to display devices, cable television, network streaming, and physical CDs must all keep up with the content. This requires all-round advancement of technology and full-scale follow-up of content. To accomplish this, the project is vast and it goes without saying that it will be a very time-consuming process. Not to mention 4K, even if we go back and watch 1080p, there is still a lot of DVD content on the market. TV Standard Definition Channel still occupies a considerable market, which is a good proof.
Not only the content, but also the technology of shooting equipment and storage media can not keep up, otherwise those mentioned before are simply not talked about. In order to follow all aspects of technology and content, we must face the conservative resistance of the old technology and people's resistance to new things. The challenge is too many.
Although hardware manufacturers and software vendors in the 4K era are all consciously making efforts, they can only accelerate, but they cannot be achieved overnight. The 8K will face more problems in the future. There are few devices capable of shooting 8K videos. Its huge data volume is also difficult for the average consumer to accept. In addition, the limited living room area of ​​the average user is also one of the main factors that limit the 8K's ability to use its own advantages.
Competition has begun
Of course, we are not saying that the technology related to 8K is useless. It is extremely important in professional fields such as large-scale live broadcasting. Japan’s NHK plans to use 8K technology at the Tokyo Olympics. With the further development of technologies in the future, the popularization of higher resolutions is certainly not a problem.
However, if we say that after 4K, everyone began to fight in an 8K war. It was really too late. There is room for improvement in the display brightness of the TV. It may really be the key point for the next competition of TV manufacturers.
In fact, competition has indeed begun. LG has already expressed its flagship new machine when it launched new television products. Its brightness is 15% higher than the previous generation. Samsung’s new flagship uses QLED technology, and officials claim that its peak brightness can reach between 1,500 nits and 2000 nits. What amazing effects will the 4000 nits bring?
