In March 2019, the Ministry of Industry and Information Technology, the State Administration of Radio and Television, and the Central Radio and Television General Station issued the "Ultra HD Video Industry Development Action Plan (2019-2022)" (hereinafter referred to as the "Action Plan"), requiring 4K first and 8K "The overall technical route, vigorously promote the development of the ultra-HD video industry and related applications.
Industrial outbreak "horn" blows
The release of the "Action Plan" is a huge positive policy for the video-related industry. It is like the "Thunder" before the storm, which blew the "horn" of the 4K Ultra HD industry. As soon as the action plan was issued, the ultra-high-definition video concept stocks of A-share listed companies rose sharply the next day. Hikvision, Dahua shares, LED screen suppliers Liard and Zhouming Technology of the security industry were all affected by favorable news. From the changes in the capital market, we can see people's attention and expectations for the ultra-high-definition video industry.
Ultra-high-definition video is undoubtedly a huge market. It is estimated that by 2022, the overall scale of China's ultra-high-definition video industry will exceed 4 trillion yuan, the 4K industrial ecosystem will be basically improved, and 8K key technology product development and industrialization will be breakthrough, forming a group of international Competitive enterprise.
Under the impetus of technology and policy, the enterprises that are the first to be laid out will benefit for a long time. For developers, whether it is the first to deploy large-screen 4K, 8K technology, BOE, Liard, and Jichuang North will bring a broader Market space. Industry experts said that the introduction of the "Action Plan" will be a good news for ultra-high-definition video and even the entire audio-visual industry. It has given guidance to the policy level and the market, and has the benchmarking significance of future action indicators.
Small-pitch led display welcomes development opportunities
To achieve high definition of led display, it necessarily means that the LED dot spacing is getting smaller and smaller. In addition, contrast is also one of the key factors affecting visual effects. Generally speaking, the higher the contrast, the clearer and more conspicuous the image, the brighter the color, the higher the contrast. It is very helpful for the sharpness, detail performance and gray level performance of the image. Contrast has a greater impact on the dynamic video display. Because the light and dark transitions in the dynamic image are faster, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process.
At present, there is no major technical problem in the display of 4K ultra-high definition display on led display. Nowadays, the industry's small-pitch led display mainstream has entered the P2.0 era, P1.2, P1.5 and other small-pitch products are also increasingly mature, and market application requirements are increasing day by day. The rapid development of small-pitch led displays provides hardware support for the development of such ultra-high-definition displays. To achieve 4K high-definition display of led display, only small-pitch led display can take on this task.
In the future, with the development of ultra-high-definition display, the small pitch will develop below P1.0, and this will undoubtedly promote the development of COB and Mini/Micro LED. In the future, the LED display will eventually become 8K.
Conclusion: It is true that the 4K application of led display is still in its infancy, and there is still a long way to go in the future. However, with the promotion and implementation of the ultra-high-definition frequency industry development plan, the scale of the ultra-high-definition video industry will continue to grow, the technological innovation capability of the enterprise will be enhanced, and the supporting construction of the surrounding industrial system will be promoted. The short-board of the LED display in this aspect will gradually be supplemented. Qi.
