Recently, the display field has released two heavy news. The first is IHS Markit's estimate that the 8K TV display will be used for the first time in the market in 2018, and will be the first year of 8K use in 2018. Ricky Park, director of IHS Markit, said: "Since Ultra HD has rapidly replaced Full HD in the oversized TV display market, panel makers are willing to offer higher resolution differentiated products. In 2018, it will become an 8K resolution TV display. The first year."
Coincidentally, this year's CES conference showed that several big players in the industry have also started the sleek mode, and all kinds of new technologies and new products are on display. Among the many products on display, 8K is the focus of everyone's common technology. . In fact, everyone has been extremely enthusiastic about 8K in these years. Although Xiaobian himself is not used even for 4K, since Japan announced that it will use the 8K signal to broadcast the 2020 Olympic Games, Xiaobian also yearns for 8K. It.
It is well known that higher definition is also an eternal topic for the security industry. If 8K can be applied in the security industry, it will inevitably bring new technical weather to the security industry.
For the security industry, the higher display technology brings the most intuitive core value is that the image is clearer and the details are more abundant. These clearer and richer pictures just meet the development needs of security intelligence. At the same time, for security vendors, clearer pictures and richer picture details have higher analytical value, which means more. Market opportunities.
The rich details of the 8K screen allow each department to share information. In the same scene, there is no need to set up multiple cameras in order to see different areas, saving investment costs. It can better restore the real details in the same scene. Even if random events occur, each business department can use the same camera to find the points of interest in the same image. After multi-stage amplification, it can still be obtained. The high-definition detail picture realizes monitoring under all weather and all scenes without changing the number of cameras, focal length and angle. This means that the 8K display will be better in applications such as safe city, highway, airport, and train station.
However, is the first year of 8K display really coming? Now that I talk about the 8K application, is the time really up? Especially in its application in the security industry, is it too early? To answer these questions, we need to first look at the basis of IHS's judgment that 2018 will become the first year of 8K resolution TV display.
IHS judges that 2018 will become the first year of 8K resolution TV displayAccording to market data, ultra-high-definition panels will account for more than 98% of the 60-inch or larger display market in 2017. According to IHS, in 2018, TV panel suppliers plan to mass produce 8K (76804320) displays, which account for about 1% of the 60-inch or larger display market. In 2020, it will reach 9%. In 2018, it will become 8K resolution TV display. Screen year.
IHS analysts said that due to UHD's popularity in the ultra-large-size TV display market, panel makers will increase the availability of higher-resolution differentiated products to leverage high-end products to provide profit margins.
The data on the supply side seems to confirm this judgment. China Taiwan Group started to develop 8K panels in 2017, and launched the first 8K LCD TV display in the fourth quarter of 2017. The screen will first be sent to Sharp TV and China. Brand supply. At the same time, Sharp also produced the first 70-inch 8K LCD TV display in the fourth quarter of 2017. In 2018, the 8K roadmap shows that Samsung Electronics and Sony are driving the market; BOE and CLP Panda are currently planning to develop 8K LCD TV panels in the second half of 2018.
From the above data, especially looking at the planning of 8K display screens in several large display companies in 2018, it seems that the application of 8K is just around the corner, and there is nothing wrong with saying that 2018 is 8K. However, the commercialization of a new technology is not just a technical upgrade. We don't mention the video source, transmission and so on in the civilian display market. We look at the application of 8K technology in the security industry. We can find that the change of technology is not so easy.
8K use is an entire industry chainThe emergence of 8K provides a very good development opportunity for the security industry in terms of clarity, but there are many problems in 8K applications that need to be solved. First of all, 8K brings more video surveillance to the front-end image acquisition part, and a complete video surveillance system, in addition to the front-end acquisition, also includes image and video storage, transmission, codec, intelligent analysis, etc. + The complex process of the backend. However, 4K brings ultra-high definition image quality and high resolution, but also brings a series of problems such as high bandwidth, high storage, and high bit rate.
This is an industrial chain, from lens to sensing equipment, to coding, including back-end display devices. Only 8K applications can be realized in all aspects of the industry chain, and 8K has real application space. Although we have made some breakthroughs in storage and encoding, we have restricted the 8K application for the back-end decoding display device; the high bandwidth required for transmission; the physical pixel limitation of the display device. In fact, let alone 8K, for the time being, 4K application problems have not been completely solved, and still suffer from the above problems.
Cost is a big problemAs mentioned above, the application of 8K technology means clearer surveillance images, which means larger video files, which will require more advanced transmission technology and higher bandwidth requirements, which means big In addition to the network transformation of the area, larger video files also put forward higher requirements for storage, such as massive data storage, query, node load balancing, backup disaster recovery, etc., which are urgently needed to be solved. Driven by the high-definition video surveillance and large-scale networking, the video surveillance system has entered the era of data blowout, and the demand for data storage and data analysis is very prominent. These will inevitably bring higher costs.
Market acceptance is also a big problemAlthough the pursuit of clarity is almost a common dream of all mankind, this does not mean that the market can accept 8K applications so easily. Because although 8K can indeed bring more development opportunities for the security industry, but the market has been very rational for the consumption of higher-definition technology, I do not know, the previous generation of technology shown so far, 4K application is also experienced for many years of floating After the ups and downs, there are still many problems, and there is still no large-scale application. The market pays attention to the price/performance ratio. Consumers are not eager to get rid of new technologies. For businesses, how to implement 8K technology to affordable, affordable HD is a responsibility of manufacturers. It also takes time to run in.
to sum upBased on the above, we can find that although the development of 8K technology is in full swing, many people have shown high confidence in the commercial application of 8K. However, after calming down the rational analysis, we can find that it is too early to talk about the application of 8K at this stage, especially the application of 8K in the security industry.
However, this does not mean that I am looking at the value of 8K technology. People's pursuit of clearer images is endless. Moreover, the trend of security industry towards higher definition is a foregone conclusion. 8K is ushered in a comprehensive security industry. Commercialization will not be used for a long time, but it seems that it is not 2018 in Xiaobian.
