A few days ago, the Ministry of Industry and Information Technology, the State Administration of Radio and Television, and China Central Radio and Television jointly issued the "Ultra HD Video Industry Development Action Plan (2019-2022)". It is estimated that by 2022, the overall scale of my country's ultra-high-definition video industry will exceed 4 trillion yuan, the number of ultra-high-definition video users will reach 200 million, the 4K industry ecosystem is basically complete, and breakthroughs will be made in the development and industrialization of 8K key technology products. In fact, the ultra-high-definition LED display has become a very obvious trend. With the successive introduction of relevant national policies and the increasing attention and demand for the ultra-high-definition display industry, the development of the ultra-high-definition video industry will definitely promote the ultra-high-definition video industry. The increasing demand for high-definition terminals will also have a profound impact on the development of high-definition LED displays. For LED display companies, the market size of the ultra-high-definition video industry continues to expand, which will surely bring a new round of development opportunities to the industry.
It is foreseeable that a 4K ultra-high-definition storm pioneered by Guangdong Province is spreading across the country. Based on a strong industrial foundation, Guangdong Province vigorously promotes the implementation of 4K ultra-high-definition video. As an important part of the ultra-high-definition industry chain, the LED display industry Since its inception, it has experienced early single and double color to full color, and then to today’s small-pitch ultra-high-definition display, and even the development of Mini/Micro LED. The entire industry has maintained its innovative vitality, trying different processes to break the technical shackles, LED display The screen has made a qualitative leap in the display effect, high-definition, or even ultra-high-definition display, which is currently a very important direction for the development of LED displays, and the release of the "action plan" has brought inflectional opportunities to the entire industry. It will become a huge driving force to promote the continuous progress of LED display technology, and a new round of audio-visual war has begun for hundreds of companies and millions of industry employees.
(1) What kind of LED display can become a high-definition display?
Entering the era of high-definition, it is first necessary to clarify what is high-definition. High-definition LED display is defined by the "high-definition" that is commonly used in televisions at present. 720P is a high-level high-definition digital TV set by the Society of Motion Picture and Television Engineers (SMPTE). 1080i and 720p are internationally recognized digital high-definition television standards. Therefore, the 1080i format has a resolution of 1920×1080i/60Hz, a line frequency of 33.75kHz, 720p format, and a resolution of 1280×720p/60Hz. The frequency is 45kHz, 1080p format, and the resolution is 1920×1080 progressive scan. All professional format displays can be defined as high-definition LED displays.
The realization of high-definition LED display must mean that the dot pitch of the LED display is getting smaller and smaller. Reducing the dot pitch of the LED display can improve its clarity and display more delicate pictures; secondly, the contrast also affects the visual effect. One of the key factors, generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. Contrast has a greater impact on the dynamic video display effect. Because the light-dark transition in the dynamic image is faster, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process.
(2) In the ultra-high-definition era, the substitution effect will be strengthened
Under the call of the ultra-high-definition era, as the small-pitch LED large-screen display technology matures and user needs continue to change, more and more end users choose small-pitch LED large screens, DLP projection, LCD panel splicing screen traditional application scenarios , Such as hotels, conference venues, exhibitions, monitoring centers, etc. will gradually be replaced by LED ultra-high-definition displays. In the past, the large-screen splicing market was relatively low-end. It only upgraded and transformed traditional desktop LCD monitors and applied them to the market. There were many drawbacks, such as insufficient resolution, which made it difficult to reach the level of 1080p, while DLP projection was The lack of color performance, and the overall stability that needs to be strengthened, have created opportunities for the development of LED displays. In today’s high-definition era, ultra-high-definition LED display screens are now very exquisite. Then there are products that can only be viewed from a distance.
LED large-screen display technology is obviously different from DLP projection, LCD panel splicing screen and other display technologies. The biggest highlight of the small-pitch LED ultra-high-definition screen is the visual experience. Its high color reproduction ability fully retains the authenticity of colors and avoids The color loss and deviation caused by the material and light path of the display technology such as backlight, projection, etc., scientific light mixing and color mixing design, point-by-point correction technology, to achieve true color reproduction, and as seamless display technology matures, The LED ultra-high-definition display can be realized without a trace of seams, just like a seamless plane, with bright colors and complete images. The large-screen display system serves as the front-end display layer of emergency command centers, hotels, conference venues, exhibitions, and monitoring centers. The display effect directly affects the display of business platform functions, thereby indirectly affecting the efficiency of command and dispatch work, image display effects, etc. , Ultra-high-definition LED display has become a powerful force that cannot be ignored due to its more and more significant technical advantages, long service life, and a wide range of adaptable environments.
The data shows that the indoor small-pitch market size in 2018 was US$1.997 billion, an annual growth of 39%, mainly due to the continued fermentation of the ultra-fine-pitch trend in the future. At present, the largest commercial market for LED small-pitch displays comes from enterprises, education, and high-end In retail, hotels, theaters and other cultural and entertainment venues, the penetration rate of LED displays in these application fields is not high, and there will be greater growth potential in the future to replace traditional LCD, DLP and projection displays, becoming an important future for LED display companies growth point.
To be sure, the ultra-high-definition display era is destined to be an era of "a hundred schools of thought", and it will play a decisive role in the upgrading of the industry. Judging from the general trend of the current LED display development, the industry will set off a "ultra-high-definition display" boom in 2019, which will have a huge impact on the advancement of the industry’s technology and technology and the expansion of the market. The era of ultra-high-definition display will be more In an era when a variety of display technologies compete for the commanding heights of ultra-high-definition displays in the future, no matter which technology can dominate the future, it is related to the future of the industry. With the advent of the ultra-high-definition display era, where will LED display companies go? In terms of technology development, what kind of situation will small-pitch, COB, Mini LED, and MicroLED present, will become a topic for companies to explore and research. .
