LED Display Technology In The Era Of Ultra-hd Will Lead To A New Blue Ocean

- Jul 22, 2019-

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-high-definition video industry development action plan (2019-2022). It is estimated that by 2022, the overall scale of uhd video industry in China will exceed 4 trillion yuan, the number of uhd video users will reach 200 million, the basic ecological system of 4K industry will be improved, and breakthroughs will be made in the r&d and industrialization of 8K key technology products. In fact, LED display high purification has become an obvious trend, along with the relevant national policies developed and people focus on ultra-high resolution display industry and the demand increasing, high-definition video industry will promote the development of ultra-high thanh hoa end demand increase, will also have far-reaching influence on the development of LED display Gao Qinghua. For LED display enterprises, uhd video industry market scale continues to expand, will bring a new round of development opportunities to the industry.


LED display technology in the era of ultra-hd will lead to a new blue ocean


Predictably, a driven by guangdong province takes the lead in 4 k ultra hd storm is to spread across the country, guangdong province, based on the abundant industrial foundation, push 4 k high-definition video landing, as the high clear an important link in the industry of LED display industry since its birth, has experienced the early single and double color to full color, and then to today's small spacing high-definition display, even to the Mini/Micro LED development, the industry has maintained innovation vigor, trying different techniques to break the shackles, LED display happen a qualitative leap in display, hd, and even ultra hd display, At present, LED display is a very important direction of development, and the release of the "action plan" to the entire industry has brought an inflection point of opportunity, will be a huge impetus to promote the continuous progress of LED display technology, hundreds of enterprises, millions of industry practitioners of a new round of audio-visual battle has begun.


What kind of LED display can become hd display?


Into the era of hd, you first need to clear what is high definition, high definition LED display is relatively widespread used in the TV - "hd" to define, 720 p is a society of American film and television engineers (SMPTE) make high-grade high-definition digital TV standard format, and 1080 I and 720 p is internationally recognized standard of digital high definition TV, so 1080 I format, resolution of 1920 x 1080 I / 60 hz, horizontal frequency for 33. 75kHz, 720p format, resolution of 1280×720p / 60Hz, line frequency of 45kHz, 1080p format, resolution of 1920×1080 line scan, professional format can be defined as hd LED display.


The realization of hd LED display screen must mean that the point spacing of LED display screen is getting smaller and smaller. Narrowing the point spacing of LED display screen can improve its definition and make the screen display more delicate. Secondly, contrast is also one of the key factors affecting the visual effect. Generally speaking, the higher the contrast is, the clearer and more striking the image will be, and the more bright and gorgeous the color will be. High contrast is of great help to the definition, detail performance and grayscale level performance of the image. Contrast has a greater impact on dynamic video display effect. Since the light and dark conversion in dynamic images is relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such conversion process.


In the era of ultra-high-definition, the substitution effect will be strengthened


In ultra clear under the call of times, with the small distance between the LED display technology becoming mature, user demand changing, more and more end users choose small spacing LED, DLP projection, LCD panel splicing screen traditional application scenarios, such as hotel, the venue, conference and exhibition, the monitoring center will be gradually replaced by LED ultra hd display. In the past, the domestic market relatively low-end, large, joining together just to upgrade transformation of the traditional desktop LCD, is used in the market, has many disadvantages, such as the resolution is not enough, it is hard to reach 1080 p level, and the lack of DLP projection on the color performance overall stability remains to be improved, creates opportunities for the development of LED display, in an age of nowadays Gao Qinghua, high-definition LED display its picture delicate degree now very handsome, is no longer "can only far view" of the product.


LED display technology and DLP projection splicing screen, LCD panel display technology has the obvious difference, such as small distance between the LED ultra clear screen visual experience is the biggest bright spot, its high color reproduction ability, intact the authenticity of the color, avoid backlit, projection display technology of color as a result of material and light path loss and deviation, scientific blending light color mixture design, point by point correction technology, to realize in the true sense of color, and with the mature of seamless display technology, LED display screen can be achieved without a high-definition thin seam, like seamless plane, bright colors, quality image complete consistent. Large screen display system, as an emergency command center, hotel, hall, exhibition, the monitoring center of the front layer, display effect is good or bad will directly affect the function of show business platform, and thus indirectly affect scheduling command efficiency, the effects of image display, etc., high with LED display to more and more significant technical advantage, long service life, adapt to the environment widely, become a strong force can not be ignored.


In 2018, according to data of indoor small spacing between the size of the market for $1.997 billion, up to 39% annual growth, mainly comes from the future trend of the ultra small spacing of continuous fermentation, the LED display screen largest commercial market small spacing from business and education, high-end retail, hotels and theaters and other places of cultural entertainment, LED display the current application in the field of permeability is not high, the future has greater potential to replace the traditional, LCD, DLP, and projection display has become an important growth point of LED display business in the future.


What is certain is that the era of ultra-hd display is bound to be an era of "a hundred schools of thought contend", which will play a decisive role in the upgrading of the industry. Look from the current development trend of LED display, in 2019, the industry will be "ultra hd display" to upsurge, this will be the progress of the technology process of industry, and the expansion of the market have a significant impact, high-definition display time will be a variety of display technology for the future ultra-high resolution shows the commanding heights of the era, no matter what kind of technology can dominate the future relationship between the industry of the future. In the era of ultra-high-definition display, LED display enterprises will be where to go, in the development of technology, small spacing, COB, Mini LED, MicroLED and what kind of situation will present, will become the enterprise to explore, to study the topic.
