LED to enter the LCD splicing market?
LED displays have been quietly developing behind the popularity of liquid crystal display devices. In the market where the LCD screen cannot be displayed, the LED display screen is struggling to attack, and various outdoor large screens are all LED products. The development of LED displays is also receiving much attention. Especially with the development of the information high-speed era, LED display screens have become blue-chip stocks, attracting large-scale investment around 2010. At various exhibitions, LED displays have become the protagonists of the show. However, this kind of wild development has also brought vicious competition. After several years of bankruptcy and mergers and shuffling, today's LED display industry has experienced a bitter pain, but this has also allowed the industry to embark. With the trend of healthy development, today we will talk about the present and future of LED display. 
LED light-emitting diode (English: Light-EmittingDiode, referred to as LED) is the core device of LED display. Such semiconductor technology-based light-emitting devices are currently used in many fields, such as illumination, liquid crystal backlighting, and self-imaging, and can be realized by using LEDs. Due to structural stability and the like, LED light-emitting diodes have many advantages, such as long service life, small current required, compact size, and pure color of illumination, etc., and these characteristics can be used to achieve different illumination effects. The principle of LED imaging is that LED light-emitting diodes can emit light of three primary colors.
LED light source structure
LED light-emitting diode is a technology that directly converts the injected current into light energy. When it is in the forward working state (that is, the forward voltage is applied to both ends), when the current flows from the anode of the LED to the cathode, the semiconductor crystal emits different from ultraviolet to infrared. The color of light, the intensity of light is related to current. Friends who are familiar with optical theory know that red, green and blue can be emitted, which means that it can be used to display pictures. In theory, as long as the LED light-emitting device is small enough.
Therefore, how to reduce the LED luminous volume is the key to the development of this industry. In addition, the development of control systems and drive systems is also crucial. After 5 to 6 years of development, LED displays can now meet many types of applications. We used to see the use of large-scale LED displays during the Spring Festival night. In addition, the transportation industry, the hotel industry, and the retail industry are all The LED display can often be seen.
So why is the LED display widely optimistic? First of all, the market volume is large. At present, the LCD screen is a familiar display form. In addition, there are two mainstream technologies of projectors and LED displays. Although LCD splicing can meet certain large-screen requirements, but the gaps in splicing and the inability to use indoors Let the LED screen have a great application prospect in an open environment. Transportation, hotel, retail, medical, performance. Aviation and other industries have large screen needs. At present, many of these needs to be met by LED displays. Only such screens can resist glare and are not afraid of the sun.
Small pitch LED screen real shot
Secondly, with the shrinking size of LED components, many manufacturers have begun to explore the indoor market, including conferences and even homes. These used to be the domain of LCD screens and projectors. Nowadays, as the volume of LED components is reduced, the effect of the picture is continuously refined, so that it can meet more demands. At a relatively close distance, LED displays that can be considered are also used. Therefore, the market for such display technology is slowly expanding.
Spring Festival Evening also applied a lot of LED screens
In addition, due to the rapid expansion of the LED display industry in the past few years and fierce competition, many companies with weak capabilities have withdrawn from the market, so that homogenization competition tends to ease, and major manufacturers do not have to fight price wars, and the profit margin of products begins to increase. In this way, more funds can be invested in technical research, thus promoting competition differentiation. As the unit price of the product begins to stabilize, various customized, personalized services and ancillary services are gradually maturing, which also ensures the healthy development of the LED display industry.
Finally, the healthy development of the supporting industry. The size of LED components is getting smaller and smaller, and the corresponding IC driver, hardware components, control system, and intelligent management system are also beginning to develop. It is also necessary to thank the cruel competition in the past few years, so that the water in the industry gradually begins to squeeze out. Some companies with technical strength began to emerge.
In the desktop display market, 4K displays have always been criticized, although the resolution is high, but the actual application effect has a lot of flaws. But for the big screen field, the application of business needs the help of ultra high definition. At present, LED displays already have 4K resolution, and even 8K resolution does not have much technical pressure. Traditional applications such as hotels, conference halls, exhibitions, and control centers require ultra-high-definition LED displays. Their fine images, stable working capabilities, and increasingly cost-effective purchase, installation, and maintenance costs will gradually erode the original. The projection of the fusion market.
4KLED display has appeared
The obvious advantage of the high resolution of the LED display is the modular installation, which is different from the high resolution of the LCD screen. The LED display can be transported and installed by module. After installation, there is no obvious seam. Therefore, the LED display can realize a huge screen size. Once a manufacturer exhibited a giant LED 8K display screen with a width of more than 30 meters, the effect was very shocking.
In addition, LED ultra-high definition display screen has other advantages, such as playing various content at the same time, with fast response without smear, high refresh rate without stroboscopic, high gray level and brightness adjustable, wide color gamut and wide angle, intelligent Transmission and control systems, etc., which are unmatched by the other two technologies. Can meet a variety of demanding studios, control centers, dispatch rooms and conference rooms and other military, aerospace, media, exhibitions, hotels and other applications.
In addition to the expansion of the LED display market, its original market upgrade is also a market opportunity that cannot be ignored. In the past, LED displays faced new upgrades due to the large spacing and aging of products. Walking down the street, we can often see the screen flickering, or the rough LED screen, these products have lagged behind, it is clear that new alternatives are needed. With the continuous development of information technology, the demand for screens continues to grow. Old-fashioned screens can't meet the needs of users, and they can't meet the needs of merchants. In the next few years, there will be an upgrade boom.
In addition, the old-fashioned screen support for new features is also lacking. At present, the popular touch and ultra-high-definition, 3D and intelligent interaction functions are not implemented on the old-fashioned LED screen. The functions to be carried by the LED screen in the future are definitely not only simple to display, but also in the development of interaction. There will be new developments, and interactions with customers and users will require new experiences. This is also the reason to stimulate businesses to upgrade the LED display.
Summary of the full text:
According to calculations, the market size of LED display will exceed 80 billion yuan in 2020, which is two to three times that of today's market. Therefore, in the past 10 years, there has been no obvious unfavorable factor in the development of LED display, from technological development to market demand. As well as the function development, the current LED display market development is relatively healthy. After a scraping competition, the market for LED displays has entered the fast lane of development. In the large screen field, it will gradually erode the projection and LCD splicing market. This is a very obvious trend. The development of LED display in the Chinese market is also a high-speed rank in the world, and there will be great achievements in the future.
