The domestic digital back projection display wall market has experienced a rapid growth of 10 years. At present, the market size has climbed to more than 4 billion yuan per year. It is predicted that the industry will maintain an annual growth rate of more than 30% in the next five years, and gradually realize market scale and brand concentration.
The rapid development of the digital back projection display wall product market has also led to the change and advancement of product technology in the video wall market. The display unit technology is mainly based on DLP splicing, and gradually transitions to the market structure of LCD, PDP and DLP three splicing unit display technologies. In particular, the emergence of LCD splicing display walls has made DLP splicing wall products face more intense market competition and potential market substitution effects. Under this background, the emergence of LED light source rear projection splicing wall has become an important fulcrum for the development direction of the three major technological competition patterns of the left and right splicing wall industry.
LED light source technology DLP splicing wall advantages
LED (Light Emittting Diode), also known as inorganic light-emitting diode, is a solid-state semiconductor device that converts electrical energy into visible light, which directly converts electrical energy into light energy. The LED itself is a transistor, and the core circuit features a PN junction. It is usually made of a III-IV compound such as GaAs (gallium arsenide), GaP (gallium phosphide), or GaAsP (phosphorus arsenide). In this transistor, carriers flow in the PN junction, which can directly convert electrical energy into light energy.
LED technology is one of the greatest inventions in the history of human light sources, comparable to the invention of incandescent lamps and lasers. LED light source is considered to be the dominant light source technology for human beings in the future, and will become an important supporting industry in the field of human light source application. It is also one of the new high-tech industries that China supports and develops. In terms of display light sources for projectors, especially DLP rear projection splicing wall unit products, LED technology has significant advantages over traditional mercury lamp technology:
1) LED backlights have a better color gamut. Its color expression is stronger than the various mercury light sources widely used in the current DLP rear projection display unit, which can make a good complement to the rear projection display technology with insufficient color display effect, and the color reproduction effect is better.
2) The service life of LED can be as long as 50,000-100,000 hours. This is the current DLP rear-projection light source with only 1000-6000 hours of light source life is unmatched, almost 100% match between the light source product and the optical machine life, equipment maintenance cycle is greatly extended, the customer's comprehensive cost of ownership is significantly reduced.
3) Full digital control. The LED light source is a digital light source, and the digital 01 code of the control signal can be directly loaded onto the light source chip after power amplification, and does not require excessive control flow. The brightness adjustment range of the illuminating effect is larger, the color control precision is higher, and the contrast can also achieve more ideal display effects and test values. With full digital control, white balance adjustment is also easier, and color temperature control is simpler without affecting brightness and contrast.
4) It is an innate parallel light source. LED is a kind of planar light source. The most basic light-emitting unit is a square package with a length of 3 to 5 mm. It is easy to combine into a surface light source with a given area and has good brightness uniformity. This is extremely suitable for projection display technology to produce high quality and uniform picture effects.
5) Security. The LED uses a low voltage power supply of 5 to 24V, which is very safe and the design of the power supply module is quite simple. The LED light source is a solid-state light source, which is not sensitive to air pressure. It is simple to apply in the plateau and safer to earthquake for handling and movement.
6) Environmental protection. The LED light source does not produce any dangerous rays, and there is no toxic substance such as mercury; the LED light source has higher luminous efficiency and the same brightness can save more energy.
7) Cheap. In the long run, the production cost of high-grade LED light source with the same brightness and life will be lower than that of ordinary mercury light source, which is beneficial to the DLP rear-projection wall to reduce procurement and owning costs.
From the above advantages, we can see that the advantages of LED light source compared with the traditional light source are not only at a certain point, but completely surpassed. This kind of progress is undoubtedly revolutionary for the rear projection splicing wall.
The challenge of DLP video wall is to protect the life-saving straw of DLP throne
The emergence of LED light source products is of great significance for DLP splicing wall products. In recent years, the large-screen splicing display market has shown a state of three-legged. Among them, the market share of LCD splicing wall is close to 25%, PDP plasma splicing wall is about 4%, DLP rear projection splicing still maintains an absolute market share advantage of 68% (other splicing technology occupies 3% share), but this Does not indicate that the DLP splicing technology market throne does not face the risk of being replaced.
Although the overall technical system of the PDP splicing wall is relatively mature, it has not been well solved in the problem of product cost performance and the natural bottleneck of the plasma display. This has greatly hindered the market penetration of PDP splicing products. LCD LCD splicing wall products, although the splicing seam can only be as small as 6.7 mm, compared with DLP technology, it also has a long technical climbing path, but the low price of the product makes it have the advantage of post-production, occupying A lot of low-end market share.
Compared with DLP splicing walls, LCD and plasma splicing undoubtedly have an absolute competitive advantage in terms of product volume, maintenance, and especially lamp replacement. In recent years, the technology of LCD splicing has been advancing rapidly. With the emergence of more advanced products in the future, the seams will inevitably become smaller. The technical staff of the industry believes that the seam of the LCD splicing is also expected to be controlled to about 2 mm. If this is achieved, the competitive advantage of the DLP rear-projection splicing product will inevitably become obvious.
Among the three major display wall technologies, the weakness of DLP splicing technology in overall cost, as well as the overall cost of ownership and maintenance cost, are caused by the traditional mercury lamp source. Due to the use of mercury light source, the contrast and color performance are greatly limited, and the life of the bulb is not long. It needs to be replaced continuously. The color wheel used with the bulb should be frequently maintained. Due to the high frequency of maintenance, the optical path part cannot be completely closed. Design, dustproof and other properties have been affected, further increasing the maintenance strength. If you replace it with an LED light source, the above problems can be solved.
In theory, the LED light source DLP rear projection splicing wall will not be inferior to other technical products such as liquid crystal splicing, plasma splicing, etc. in terms of volume, and other aspects will not have obvious disadvantages, but also can be controlled in the seam. Maintain a strong lead in DLP. Therefore, it can be seen that the LED light source brings more than “weakness†to the DLP splicing technology, and it can make it the “winner†among the three splicing technologies, and comprehensively solve the challenges faced by the current DLP splicing products. The light source has become a life-saving straw to defend DLP's market position in the field of large-screen splicing walls.
Status of LED light source DLP splicing wall application
Although the LED light source DLP splicing wall technology has leading advantages, an advanced technology from the laboratory to the market will not be smooth, and users need a process to understand and accept a new technology. At present, the application of LED light source in DLP splicing wall products is still in the “testing water†stage.
The emergence of the domestic LED light source splicing wall product prototype was in mid-2009. During this period, manufacturers mainly showed application prototypes, optical model and R&D concepts. In 2010, the mainstream DLP back-projection splicing wall enterprises in the domestic market began to enter the practical stage of commercialization of LED light sources. Giant Yang, GQY, Mitsubishi, Weichuang, Barco and other companies have launched DLP splicing wall solutions for LED light sources. LED light sources are an important development direction of DLP splicing technology. At this point, there is almost no disagreement in the industry. But for LED light sources to bring commercial value to the DLP splicing market, different companies have different understandings.
Some companies in the industry said that although DLP splicing display wall traditional technology products are frequently maintained, on the one hand, frequent maintenance and consumables replacement provide a larger profit margin for the industry. A well-known projection LED light source supplier in China indicated to the projection era that according to the company's contact with many market customers, including international giants, LED light source products may be extremely wary of the profits of traditional DLP video wall market. This is one of the reasons why these companies have positioned the price of LED light source DLP splicing wall products too high and earned excess profits.
According to another study, the actual cost impact of LED light source technology on DLP splicing units is very limited, often in the range of 10-45%. Therefore, if the price of the main LED light source products in the market is about twice as high as that of the traditional products, the actual profit level of the manufacturers will increase by 2-5 times, and the added value obtained by the customers due to the advantages of LED technology such as less maintenance and replacement of the light bulb consumables. Consumed by the company's high pricing strategy.
The fact that technological advancement has not made the final consumer profitable has caused the profits of the manufacturers to rise. This fact has caused the significance of the LED light source products in the DLP splicing industry to remain more on the basis of “showing the image of the enterprise R&D to customersâ€. Some international giants have only achieved practical breakthroughs in application cases, and have not formed a large-scale customer base.
Since the launch of the domestic LED light source DLP splicing projection unit market in 2009, after a period of fiery heat in the start-up period, how to further break through the market structure has become a problem that the whole industry has to think deeply. Pjtime.com believes that the speed of its market development will depend on the enthusiasm of the manufacturers for the promotion of this product, the control of large-scale production costs, and the continuous investment in research and development.
LED light source DLP splicing wall industry needs to "take the lead"
The development of domestic LED light source DLP splicing display wall market is currently in the "multiple participating manufacturers, the main push manufacturers are not", "the concept of vendor awareness is important, but the action is hesitant", "customer market products prices are high, new technology has not brought obvious to customers The bottleneck of the development of “new valueâ€. For the break of this situation, industry experts believe that the most needed is to have a "leading big brother" style brand, can play the role of industry leaders.
According to incomplete statistics, the Chinese market has become the world's largest LED light source product manufacturing and consumer market, especially in the LED light source rear projection TV, urban lighting LED engineering, LED street lights and other markets, the growth of the domestic market has become the development of the global market. power. Among them, the LED engineering lighting market, the domestic market share of 40% of the global market, highlights the domestic customers' preference for economic and environmental protection of new energy lighting.
In fact, the large-scale introduction of energy-saving and environmentally-friendly LED light source technology has become a national strategy, and it has become an important technical means to ensure that the Chinese government can accomplish the energy-saving and emission reduction targets made by the international community. Standing in the scientific development and advanced technology to serve the country's economic progress, Juyang Technology first systematically launched a series of LED light source DLP display products in 2010, and hopes to fill the global LED light source DLP splicing market without a leader. Whitespace.
According to Juyang Company, Juyang LED light source DLP projection unit is the world's first XGA resolution serialized product. The product size covers 50, 60, 67, 80, 84 inches and other mainstream application size lines, most of which are products. It is the first time in the world. "Ten years of grinding a sword", long-term technical accumulation and the wisdom of the future development of LED light source technology has made the leading position of Juyang today.
Juyang said: "The popularity of LED light source DLP large-screen splicing wall, no matter how difficult, is a technology worthy of investment. Juyang will continue to innovate not only in traditional DLP technology, LCD splicing technology, but also in LED The revolutionary technology of light source has become the market leader – because for DLP splicing wall manufacturers, there is no future without LED light source."
When the entire DLP splicing industry is hesitant to promote the LED light source, the move by Juyang is undoubtedly bringing hope to this new technology. It is expected that under the leadership of Juyang, the entire LED rear projection splicing wall will enter a period of rapid development.
Responsibility achievement "leadership"
For the world's first large-scale launch of a series of LED light source products, it will inevitably face huge market challenges. In the background of the industry colleagues, and even the international giants can not make a big difference in the LED light source rear projection mosaic wall, how can the giant ocean have a different strategy?
In response to the timing of the launch of LED light source splicing wall series products, Juyang said to the projection era that Juyang has always pursued the principle of “not seeking the first but seeking the best†in the new product strategy. Although the new product of Juyang LED light source has not caught up with the first wave of last year, it has become the first brand to serialize the entire line of LED light sources, and is the world's first manufacturer of XGA resolution LED products. In fact, as early as a few years ago, Juyang has already profoundly grasped the great value of LED light source in the future video wall market and actively reserved technology. In 2009, Juyang LED light source display splicing wall has entered the trial production stage, and after one year of rigorous testing and inspection, this year, the first full-size serialized LED light source DLP splicing wall solution was released to the global market.
"Time is late because we want to do our best." Juyang believes that DLP splicing walls are mostly used in security areas such as monitoring, command and dispatch, and strive for excellence in product quality and technology. Juyang has spent more time and energy on the development and testing of LED light source products, which is to ensure the quality of the products. It is through the most rigorous testing and testing that Juyang is confident that the first time this type of product is launched is a complete serialization solution.
It is also the strict control of product quality and this kind of user-responsible practice that makes Juyang the first commercial XGA resolution LED backlight DLP product displayed at the Shanghai Digital Signage Exhibition held recently. With excellent product performance and high praise from the audience, in addition to its long life and maintenance-free, the overall cost of ownership is low, many viewers also said after the scene: the color gamut of the product is wide, color More beautiful, the brightness can also meet the actual application needs. The reason why there is such a good color performance is because it uses many of the original ingenuity technologies of VATION, in which the fine color adjustment technology can independently adjust the seven primary colors of R, G, B, C, M, Y and W. It can also simulate various complex mixed color and transition color display modes, and perform joint adjustment of multi-primary color mixing. It greatly enriches the color adjustment means, so that the color adjustment work can be infinitely refined, bringing more close to the real color performance. Juyang said: "The good market response of this product completely exceeds the expectations of Juyang. Once it is launched, users have placed purchase orders."
In addition, Juyang also revealed another important information of its series of LED light source DLP splicing wall products: this will be the world's first civilian-type LED light source DLP splicing wall products. Juyang said that although the series achieved lower maintenance costs and zero consumables, the price has only increased by about 30%. The basic price increase is the inherent cost increase of LED light source products: unlike most industry players, Juyang does not earn extra value from LED light sources.
In fact, the high price of LED light source DLP splicing wall products has seriously affected the development of this industry. The high profit sacrificed is the commercial value brought by the advanced technology of LED light source. The profit of the industry and the waist pocket of the manufacturer ruin the prospect of industrial development. The high price strategy can only expand the market of LED light source products. Both lose and hurt, industry experts think so.
In the discussion of LED light source DLP splicing wall products, most people in the industry believe that a responsible company can truly provide high-quality products and companies that benefit customers can become the market leader. Only this market has a "leader", LED light source DLP splicing wall industry can really usher in great development. Undoubtedly, the launch of Juyang LED light source series solution products has brought an "industrial leader" to the entire LED splicing wall industry.
The person has no head and does not go, the bird has no head and does not fly. Under the leadership of Juyang LED light source DLP rear projection splicing products, the global splicing wall market will inevitably enter a new field. Many technical advantages of LED light source, traditional features of DLP display wall technology combined with Juyang's strong R&D and brand appeal, especially responsible industrial strategy, truly benefiting customers' market policies, LED light source DLP splicing wall products are rapidly popularized The door has been slowly opened.
