Internal volume can be said to be the hottest topic this year. In today's increasingly competitive environment, everything seems to be involuntary.
In the development of the ultra-high-definition industry, this industry, which represents the most advanced display technology, now seems to be trapped in an incoil.
From 1080P to 4K and 8K, the development of the ultra-high-definition industry seems to be advancing only around resolution. Is this just an involution?
What is Ultra HD technology?
Most users should be very unfamiliar with the word 8K. In daily life, the most common video content and display devices are basically 1080P (1920*1080) resolution level.
And the higher 2K and 4K have gradually become common in recent years, especially in high-end mobile phones, TVs and monitors, the emergence of 2K and 4K has become more common. But even so, from the overall market share, it still only occupies a very small part.
What is the difference between Ultra HD resolution and general 1080P resolution? A major factor affecting the resolution is the number of pixels that can be displayed.
Take 4K resolution, which is more common in ultra-high-definition resolution, as an example. It refers to the general term that the pixel value of each row in the horizontal direction reaches or approaches 4096 standards. 4K is only a range of standards. As long as this standard is met, it can be called It is 4K.
Compared with 1080P, the effective pixel number of 4K resolution is four times that of 1080P. When it comes to 8K, its resolution has reached 7680*4320, and the effective number of pixels that can display IDE is four times that of 4K and 16 times that of 1080P.
Ultra HD resolution can display more effective pixels, which means that it can bring a more refined look and feel to users. TV manufacturers have begun to focus on UHD. In 2019, Sharp launched the world's first 8K TV, opening the battle for the ultra-high-definition track of the world's mainstream TV manufacturers.
At the same time, the emergence of 5G technology has given strong support to technologies such as ultra-high-definition video that have great demands on network transmission speed.
The inner volume of Ultra HD is facing "internal and external troubles"
But is Ultra HD really the right path?
In this year, Warner Bros., Pixar, Amazon Prime Video, LG, and the American Society of Cinematographers (ASC), including many industry-leading companies and institutions, designed an experiment. The purpose of this experiment is to test how ordinary people are in 4K. Can you feel the difference with 8K?
This study uses a double-blind test as the main method to analyze the perception of video resolution by allowing participants to watch different 4k and 8K videos. But the result is surprising, ordinary people can hardly tell the difference between the two, which means that 4K and 8K are almost indistinguishable in the perception of ordinary people.
Although this study cannot completely deny that the human eye cannot effectively distinguish between ultra-high resolution, it also reflects to a certain extent that the human eye has a certain limit in the recognition of resolution, especially when the ultra-high resolution is recognized. Technology is more applied to display products with larger screens such as televisions. As the user's eyes are farther away from the screen, the limit of resolution will also shrink.
The ultra-high-definition resolution has actually exceeded the limit of human recognition, and continued growth is not necessarily the right direction.
In addition, the market's recognition of UHD technology is not high. As early as 2004, 4K technology was born, and until 2020, 4K technology has not yet achieved large-scale commercialization. Even with the rapid development of 5G technology as a support, the lack of market access and low consumer acceptance will affect the development of the ultra-high-definition industry.
The high price of UHD-related products is also an important obstacle preventing its large-scale promotion.
The price of the first 8K TV released was more than 300,000 yuan. Although the prices of 8K TVs after that have fallen to 10,000 yuan, relatively speaking, the price and increase are still not enough to attract consumers.
At the same time, since it is in the early stage of development, there is still great room for improvement in standard formulation and industry norms. Each panel manufacturer has different standards for defining whether it is an ultra-high-definition resolution display device. As for related ultra-high-definition video content and shooting equipment, this standard is also vague.
Under the "internal worries" that cannot show its own advantages, the ultra-high-definition industry will also face "external worries" that the market does not recognize and the standards and regulations are chaotic. Judging from the current situation, it is still doubtful whether ultra-high-definition technology is the right path.
Is it accelerating, or is it moving in the right direction?
Continuously improving the growth resolution can be simply seen as the current development direction of the ultra-high-definition industry. In this way, the UHD industry seems to have fallen into "involution".
Falling into involution means that future development will most likely fall into a dead end. So how should the ultra-high-definition industry get rid of the current continuous involution situation.
One is to deepen the exploration of application scenarios, so as to find the most advantageous breakthrough in the UHD industry.
One of the most promising applications of UHD technology is telemedicine. Under the impact of the epidemic at the beginning of this year, telemedicine technology has been widely used. Among them, ultra-high-definition display technology and 5G technology are one of the core key technologies of telemedicine.
Telemedicine needs to use remote video to help doctors realize disease diagnosis and even perform operations, which has extremely high requirements for video clarity.
However, higher-definition video resolution also has extremely high requirements for transmission speed and network delay, and the application of 5G technology can meet the needs of ultra-high-definition video communication. Therefore, ultra-high-definition technology can play a powerful role in promoting telemedicine. On the contrary, the huge market of telemedicine will also drive the rapid development of ultra-high-definition technology.
The second is to accelerate the improvement of industry standards and establish unified product and technical standards. The development of the ultra-high-definition industry has only seen substantial growth in recent years. Although the relevant technical standards have long been introduced, there are still major loopholes in the unification of the entire industry's specifications and standards.
For the stable development of the ultra-high-definition industry, it is necessary to create a unified standard and complete industry specifications. This will avoid the emergence of various different standards, affecting the development of the entire industry.
Conclusion
At present, the UHD industry has not yet become a very popular track. Compared with the previous display technology, the UHD technology has not had a disruptive breakthrough, and the price of the product is also higher, the market's recognition of UHD technology is low.
But in any case, higher resolution is still the future development trend of the display industry. In the future, ultra-high-resolution display devices paired with ultra-high-resolution video, coupled with related new technologies, can bring users a more shocking visual experience.
Ultra-high-definition technology represents the mainstream direction of the display industry in the future. When visual recognition is still the only display technology, from this point of view, the future development of the ultra-high-definition industry still has great potential. And the ultra-high-definition industry, which is developing towards higher resolution, is not necessarily "rolling in".
