LED display technology in the ultra-high-definition era will lead to a new blue ocean

Currently, the Ministry of Industry and Information Technology, the State Administration of Radio and Television, and the Central Radio and Television Station 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, and the number of ultra-high-definition video users will reach 200 million. In fact, the ultra-high-definition LED display has become a very obvious trend. With the successful introduction of relevant national policies and people’s 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 scale 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 first promoted by Guangdong Province is spreading to the whole country. Based on a solid 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 birth, has experienced early single and double color to full color, and then to today’s small-pitch ultra-high-definition display, and even develops towards Mini/Micro LED. The screen has made a qualitative leap in the display effect. High-definition and even ultra-high-definition display is currently a very important direction for the development of LED displays. The release of the “Action Plan” has brought an inflection point 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 battles with hundreds of enterprises and millions of industry practitioners has begun.

What kind of LED display can become a high-definition display?

Entering the high-definition era, we must first clarify what is high-definition. High-definition LED displays are defined as “high-definition”, which is commonly used in TV sets. 720P is a high-level high-definition digital TV formulated by the Society of Motion Picture and Television Engineers (SMPTE). 1080i and 720p are internationally recognized digital high-definition TV standards, so the 1080i format has a resolution of 1920×1080i/60Hz, a line frequency of 33.75kHz, and a 720p format with a resolution of 1280×720p/60Hz, The frequency is 45kHz, the 1080p format, the resolution is 1920×1080 progressive scan, and the professional format display can be defined as a high-definition LED display.

The realization of a 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 greatly improve its clarity, and the screen display is more delicate; secondly, the contrast also affects the visual effect. One of the key factors, generally speaking, is the higher the contrast, the clearer and more eye-catching the image, and the brighter and brighter the color. Contrast has a greater impact on the display effect of dynamic video. Because the light and dark transition in dynamic images is relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such a transition process.

The substitution effect will be strengthened in the ultra-high-definition era

Under the call of the ultra-high-definition era, with the maturity of small-pitch LED large-screen display technology and the changing needs of users, more and more end users choose small-pitch LED large screens, DLP projection, and LCD panel splicing screen traditional application scenarios, such as hotels, 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, just upgrading and transforming the traditional desktop LCD display and applying it in the market, there are many drawbacks, such as insufficient resolution, it difficult to reach the level of 1080p, and DLP projection is in The lack of color performance and the overall stability still needs to be strengthened, all of which have created opportunities for the development of LED displays. Then there are products that can only be seen from a distance.

There are obvious differences between LED large-screen display technology and 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. The color loss and deviation caused by the material and light running path of display technologies such as backlight and projection, scientific light mixing and color mixing design, point-by-point correction technology, to achieve true color reproduction, and with the maturity of seamless display technology, The LED UHD display can achieve a seamless surface without a trace of the seam, with vivid colors and complete image quality. The large-screen display system is used as the front-end display layer of the emergency command center, hotel, venue, exhibition, and monitoring center. The quality of the display effect directly affects the display of business platform functions, which indirectly affects the efficiency of command and dispatch work, image display effects, etc., Ultra-high-definition LED display has become a strong force that cannot be ignored with more and more significant technical advantages, long service life, and wide adaptability to the environment.

The data shows that the indoor small-pitch market size in 2018 was 1.997 billion US dollars, with an annual growth rate of 39%, mainly due to the continuous 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, 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 at present, and there is greater growth potential in the future to replace traditional LCD, DLP and projection displays, becoming an important future for LED display companies. growth point.

What is certain is that the era of the ultra-high-definition display is destined to be an era of “a hundred schools of thought contending”, and it will play a pivotal role in upgrading the industry. Judging from the current development trend of LED display, in 2019, the industry will set off an upsurge of “Ultra High Definition Display”, which will have a huge impact on the progress of the industry’s technical process and the expansion of the market. In an era where various display technologies compete for the commanding heights of future ultra-high-definition displays, no matter which technology can dominate the future, it is related to the future of the industry. When the era of the ultra-high-definition display is coming, where will LED display companies go? In terms of technology development, what kind of situation will small pitch, COB, Mini LED, and MicroLED appear in that will become the subject of enterprises to explore and research?
