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) Quel type d'écran LED peut devenir un écran haute-définition ?
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 19201080i/60Hz, a line frequency of 33.75kHz, 720p format, and a resolution of 1280720p/60Hz. The frequency is 45kHz, 1080p format, and the resolution is 19201080 progressive scan. All professional format displays can be defined as high-definition LED displays.
La réalisation d'un écran LED haute-définition doit signifier que le pas de point de l'écran LED devient de plus en plus petit. La réduction du pas de point de l'écran LED peut améliorer sa clarté et afficher des images plus délicates. deuxièmement, le contraste affecte également l'effet visuel. L'un des facteurs clés, d'une manière générale, plus le contraste est élevé, plus l'image-est claire et accrocheuse, et plus la couleur est claire et lumineuse. Un contraste élevé est très utile pour la clarté de l'image, les performances de détail et les performances de niveau de gris. Le contraste a un impact plus important sur l'effet d'affichage vidéo dynamique. Étant donné que la transition clair-sombre dans l'image dynamique est plus rapide, plus le contraste est élevé, plus il est facile pour l'œil humain de distinguer un tel processus de conversion.

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.
La technologie d'affichage sur grand écran LED-est évidemment différente de la projection DLP, de l'écran d'épissage de panneau LCD et d'autres technologies d'affichage. Le plus grand point fort de l'écran ultra-haute-définition-LED à petit pas est l'expérience visuelle. Sa capacité élevée de reproduction des couleurs conserve pleinement l'authenticité des couleurs et évite la perte de couleur et la déviation causées par le matériau et le chemin lumineux de la technologie d'affichage tels que le rétroéclairage, la projection, etc., le mélange scientifique de lumière et la conception de mélange de couleurs, point {{4 }}par-la technologie de correction de points, pour obtenir une reproduction fidèle des couleurs, et à mesure que la technologie d'affichage continue mûrit, l'affichage LED ultra-haute-définition peut être réalisé sans trace de coutures, tout comme un avion sans couture, avec des couleurs vives et des images complètes. Le système d'affichage grand-écran sert de couche d'affichage frontale-des centres de commande d'urgence, des hôtels, des salles de conférence, des expositions et des centres de surveillance. L'effet d'affichage affecte directement l'affichage des fonctions de la plate-forme commerciale, affectant ainsi indirectement l'efficacité du travail de commande et de répartition, les effets d'affichage d'image, etc., l'affichage LED ultra-haute-définition est devenu une force puissante incontournable en raison de ses avantages techniques de plus en plus importants, de sa longue durée de vie et de sa large gamme d'environnements adaptables.
Les données montrent que la taille du marché des petits-terrains indoor en 2018 était de 1,997 milliard USD, soit une croissance annuelle de 39 %, principalement en raison de la fermentation continue de l'ultra-fin- tendance de hauteur à l'avenir. À l'heure actuelle, le plus grand marché commercial pour les écrans LED à petit-espace provient des entreprises, de l'éducation et du haut de gamme-. Dans le commerce de détail, les hôtels, les théâtres et autres lieux culturels et de divertissement, le taux de pénétration des écrans LED dans ces domaines d'application n'est pas élevé, et il y aura un plus grand potentiel de croissance à l'avenir pour remplacer les écrans LCD, DLP et de projection traditionnels, devenant un avenir important pour le point de croissance des entreprises d'affichage à LED.
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. .
