The battle between LCD and DLP is expected to die. According to predictions, the total output value of the domestic large-screen video wall market in 2010 will be close to 4 billion for the first time, and it will also develop rapidly at an annual growth rate of 30%. The rapid development of the large-screen splicing industry has attracted the participation of many LCD splicing screen manufacturers. According to incomplete statistics, there are more than 300 manufacturers and more than a thousand integrators involved in this industry in China, which constitutes a huge splicing wall industry chain. In the large-screen splicing market, DLP rear projection splicing has always dominated. However, due to the problems of excessive power consumption and too much space occupied by DLP splicing products, it has not been possible to achieve a greater breakthrough. However, with the emergence of LCD splicing products, the market structure of large-screen splicing has undergone tremendous changes. Since then, the competition between the two major technologies of LCD and DLP has never stopped. Especially in the past two years, the two major technologies of LCD and DLP have made major breakthroughs in their respective large-screen splicing fields, and the future competition will be more intense. The stitching is only 5.3mm. The advantages of LCD splicing are obvious. Compared with traditional DLP splicing, LCD products have the advantages of high definition, wide viewing angle, high brightness, and long life. They are quickly recognized and accepted by many users. Compared with DLP splicing, LCD has a longer service life, lower power, less heat generation, and a very low failure rate. These are things that DLP rear projection splicing walls cannot do. However, due to the inevitable splicing gaps in the splicing process of LCD splicing products, this has largely hindered the development of the large-screen LCD splicing LCD splicing market. However, in recent years, upstream companies led by Samsung SID have been continuously researching and developing joint gaps.
In the first half of 2009, Samsung launched a 7.3mm LCD splicing wall and achieved very good results in the market; in the second half of the year, Samsung took advantage of the heat to achieve a minimum of 6.7mm bilateral splicing seams, these ultra-narrow-edge splicing products The emergence of LCD splicing has greatly increased both in terms of market share and number of manufacturers. Although the splicing generation of Samsung splicing products is narrower than the first generation, compared with the splicing of LCD TV splicing wall DLP which is only a few millimeters, it still makes people notice the existence of the splicing. So in 2011, Samsung once again launched a new generation of splicing products-UD55A. The new product not only expands the panel size, but also comprehensively upgrades the core technology such as LED backlighting. The bilateral stitching has reached an ultra-narrow 5.3 mm. On the original seamless stitching technology, it will present more image content and more Realistic visual effects. Moreover, the UD55A has a built-in video processor, which can support 100 simultaneous displays. At the same time, it is equipped with a Samsung MID bracket, which makes it very simple and convenient for Samsung LCD splicing wall to build a video wall; its own MagicInfo video wall technology can easily control the display content in The display on the overall video wall will push LCD splicing to the mainstream application market of the large-screen splicing market.
LED light source + high-definition DLP splicing competition is a new weapon. Faced with the strong impact of LCD splicing, some people even believe that LCD splicing will definitely replace DLP in the future and become the mainstream splicing product in the market until the emergence of LED light sources. As everyone knows, due to the use of mercury lamp light source, the contrast and color performance of DLP splicing technology is greatly limited. At the same time, the life of the bulb is not long and needs to be replaced continuously. The color wheel used with the bulb needs to be maintained frequently. Due to the maintenance of the LCD splicing display wall The frequency is large, the optical path part cannot be completely closed, and the performance of dustproof is affected to a certain extent, which further increases the maintenance intensity. But after using LED light source, these problems will be solved. Since 2010, the large-scale DLP rear projection splicing wall enterprises that are mainstream in the domestic market have really entered the practical stage of commercialization of LED light sources. Juyang, GQY, Mitsubishi, Vitron, Barco and other companies have launched DLP splicing wall solutions with large-screen LCD splicing LED light sources. LED light sources are an important development direction for DLP splicing technology. At this point, there are few companies in the industry. Disagreement. Not only that, in order to meet the user's visual needs for high-definition, but also to cater to the development of the market, large-screen splicing manufacturers have launched high-definition or even full-HD LED rear projection splicing, including like Vtron, Juyang and so on. These DLP splicing products using LED light sources have not only completely changed the poor performance of the "color saturation and color gamut" of LCD screen splicing DLP display walls, but also achieved a light source life of 20,000 hours and a "up to 5 years" "Zero maintenance" cost, can also enjoy the high-definition picture effect, greatly improved competitiveness. In theory, the use of LED light source DLP rear projection splicing wall will still be weaker than LCD splicing in volume, but it will not have obvious disadvantages in other respects, and it can maintain LCD seamless splicing screen DLP in the control of seams. Strong leading position. Therefore, it can be seen that the LED light source brings not only "weaknesses to be compensated" for the DLP splicing technology, but also a sword for the rear projection splicing to maintain the market position. In 2011, the LCD 5.3mm splicing unit was a menacing situation. Since Samsung released the 5.3mm splicing unit, many manufacturers have already stated that they will use this product as the main product of 2011. It is foreseeable that the LCD splicing will be ushered in in the future High-speed development period. But while solving the bottlenecks of dehumidifier manufacturers' light source consumables, DLP splicing products will still be a very strong opponent.
