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) Que tipo de display de LED pode se tornar um display de alta-definição?
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.
A realização do display de LED de alta-definição deve significar que o dot pitch do display de LED está ficando cada vez menor. Reduzir o dot pitch do display de LED pode melhorar sua clareza e exibir imagens mais delicadas; em segundo lugar, o contraste também afeta o efeito visual. Um dos principais fatores, de modo geral, quanto maior o contraste, mais clara e atraente-a imagem e mais brilhante e mais brilhante a cor. O alto contraste é muito útil para clareza de imagem, desempenho de detalhes e desempenho de nível de cinza. O contraste tem um impacto maior no efeito de exibição de vídeo dinâmico. Como a transição claro-escuro na imagem dinâmica é mais rápida, quanto maior o contraste, mais fácil é para os olhos humanos distinguirem esse processo de conversão.
(2) Na era da ultra-alta-definição, o efeito substituição será fortalecido
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.
A tecnologia de exibição de tela grande- LED é obviamente diferente da projeção DLP, tela de emenda de painel LCD e outras tecnologias de exibição. O maior destaque da pequena-tela LED de ultra-alta-definição é a experiência visual. Sua alta capacidade de reprodução de cores retém totalmente a autenticidade das cores e evita a perda e o desvio de cor causados pelo material e o caminho da luz da tecnologia de exibição, como luz de fundo, projeção, etc., mistura de luz científica e design de mistura de cores, ponto{{4 }}por-tecnologia de correção de ponto, para obter uma reprodução de cores verdadeiras, e à medida que a tecnologia de exibição contínua amadurece, a tela LED de ultra-alta-definição pode ser realizada sem vestígios de costuras, como um avião sem costura, com cores vivas e imagens completas. O grande-sistema de exibição de tela serve como a camada de exibição-frontal de centros de comando de emergência, hotéis, locais de conferências, exposições e centros de monitoramento. O efeito de exibição afeta diretamente a exibição das funções da plataforma de negócios, afetando indiretamente a eficiência do trabalho de comando e expedição, efeitos de exibição de imagem etc. que não pode ser ignorado devido às suas vantagens técnicas cada vez mais significativas, longa vida útil e uma ampla gama de ambientes adaptáveis.
Os dados mostram que o tamanho do mercado interno- de campo pequeno em 2018 foi de US$ 1,997 bilhão, um crescimento anual de 39% , principalmente devido à fermentação contínua do ultra-fino- tendência de arremesso no futuro. Atualmente, o maior mercado comercial para displays de LED de pequeno-campo vem de empresas, educação e alta-no varejo, hotéis, teatros e outros locais culturais e de entretenimento, a taxa de penetração de displays de LED nestes campos de aplicação não é alto, e haverá maior potencial de crescimento no futuro para substituir os tradicionais displays de LCD, DLP e projeção, tornando-se um importante ponto de crescimento futuro para as empresas de display 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. .
