LED has come again, stepped at a fine pace, did not say hello to the traditional AV big screen manufacturers have agreed on the scope of influence, rush to eat. Watching this once-rough guy, who is now so detailed, AV manufacturers are overwhelmed. Are they welcome, introduced, rejected or compromised? In 2010, LED once saved the DLP fight against the wall, successfully using LED light source to block the menacing of the LCD wall, it can be said that there is grace. But this time, it seems that instead of cooperating, it is naked to grab the site. And although both are called LEDs, it's obviously not a call before or after. The last cooperation was an LED light source. This time it was an LED display. LED displays can be said to be the top spot in the outdoor display, occupying absolute dominance, and then slowly infiltrated into the room, used in auditoriums, exhibitions, hotels, subways and other occasions that require large-scale display of the picture, and now it is even gawking to enter the command Control, security monitoring, radio and television, which are very demanding, sophisticated display, complex signals, AV large-screen manufacturers rely on the survival of the site, can not let AV manufacturers are nervous?
Benefiting from rapid economic growth and rapid expansion of urbanization in previous years, LED displays have also maintained a strong momentum of development. LED manufacturers are still living well. However, as the economy slowed down and exports decreased, the market space became crowded, and corporate orders fell and prices continued to decline as the main tone of the market. Many manufacturers expand their production lines when the economy prospered, and they are often in a situation of intermittent suspension of production. The disorderly competition of many LED companies has exacerbated the deterioration of the situation, and many companies have been forced to shut down and switch. Everyone is in the Red Sea. "Under suffering, the competition of conventional display has reached a point where the water is extremely hot.
In this market environment, all LED display manufacturers are beginning to look for their own positioning, deep dig the market segment. Some companies hope to use technology innovation to enter a number of higher market areas, such as see DLP in the high-end indoor display market applications exist in various deficiencies, Jian Jian, Chau Ming, Liad, etc. to increase the LED small pitch display The research and development of technology, to seize the traditional LCD, DLP and other splicing screen market.
Although the competition in this area is also very fierce, but compared to the LED market, it is still relatively mild, and more importantly, this area still maintains a certain rate of profit. Therefore, it is not sufficient to use this as a "blue ocean" for breakthrough development. Strange. Of course, this "cross-border" behavior is bound to move the AV display manufacturers "cake", a prelude to the competition between LED and the big screen manufacturers also opened.
He Dehe can call AV
LED display is a very mature product that has been developed for more than 20 years. From the beginning, the display of text content, followed by text and dynamic video, is widely used in indoor and outdoor large-scale advertising, stage performances, exhibitions, sports events, hotel lobby and other occasions. LEDs have the advantages of large display area, high brightness, vivid colors, easy assembly, high utilization of building space, and low maintenance cost. However, the failure to enter the mid-to-high end mainstream applications in the room was mainly due to the large distance between the LED display pixels and the strong graininess of the close-range viewing screen.
In recent years, with the development of technology, the semiconductor manufacturing process has gradually matured, LED display spacing is getting smaller and smaller, and the resolution is getting higher and higher. P4 full-color screen appeared on the market in 2011. P3 and P2.5 LED screens entered the market in 2012. In 2013, small-pitch LED screens were completely released. New products such as P2.0, P1.8, P1.5 and P1.4 emerged in an endless stream. , P1.2, P1.0 and other smaller-pitch products have also been developed and produced, and the resolution, refresh rate, and gray scale have been greatly improved.
Today, the following P2.5 products are collectively referred to as small-pitch LED displays. Its greatest advantage lies in the fact that the display is completely seamless and the natural colors of the display are true. Splicing gap is an important factor affecting the visual experience. At that time, due to physical characteristics, the mainstream DLP splicing and liquid crystal splicing in the room all had more or less seams. The development of technology can only make the seams smaller, but it cannot be eliminated. Although the projection splicing is physically seamless, there is a fusion zone, which is a test of the technical strength of the manufacturers, and it needs regular adjustment to ensure the integration of results.
The LED display with the characteristics of seamless splicing, there is a greater degree of plasticity in the stitching. The color performance is good because the color gamut of the LED is wider than the color gamut of the DLP and the liquid crystal image signal, and more colors can be reproduced, which can more accurately reflect the authenticity of the object. In terms of space utilization, the screen thickness of the current indoor small-pitch LED can already be 10-15cm. After pre-maintenance, it can completely stand against the wall.
In addition, the LED performance is better than the DLP splicing in terms of color consistency. DLP splicing consists of multiple units. There is a difference between each unit. The consistency of the color and brightness of the entire screen is the most difficult place for DLP splicing. After one adjustment, the difference will change with the increase of the use time. It needs to be run. Correct it once in a while. The small-pitch LED has a good effect on consistency. The mature point-by-point correction technology makes the adjustment process simple and easy to maintain.
Through the above we have seen that small-pitch LEDs do possess hard power and have the potential to impact the existing competitive landscape and enter high-end applications.
The penetration of small-pitch LED screens does have some impact on the big-screen market. With the continuous development of technology and the continuous decline in costs, small-pitch, high-density LED displays are gradually highlighting their advantages and are driving greater market space for application. The small-pitch LED has been applied to various areas such as city and space surveillance centers, force command centers, television studios, waiting halls, conference halls, indoor advertising, cinemas, securities finance, and education systems. However, large-screen manufacturers do not need to be too nervous. The scope of adaptation of each product is limited, and it is not possible for a product to eat all. Zhenshi Wang Huijuan believes that although LED manufacturers have extended their reach to the monitoring and production dispatch command center, and some traditional DLP well-known companies, such as Vtron, GQY, etc., have also involved in the small-pitch LED product market, but at this stage The main application area of the small-pitch LED screen is still on the display device of the large hall. Its market development in the new application field should first be positioned in the market competition with large-scale project projectors.
In any case, there is no doubt that the small pitch LED screen will inevitably encroach on the market of some traditional DLP and flat panel stitching. Whether there will be a disruptive change, in fact, depends on the perfection of small-pitch LED display products, including high-end LED display manufacturers to deepen the technology of peripheral processors, application software; LED upstream manufacturers for customer application technology innovation; LED The stability of the product; the further reduction of the cost under the premise of guaranteeing the quality and other comprehensive factors.
