In 2012, LED display is rapidly becoming a hot industry, capital investment, cross-border investment boom spawned an industry blindly optimistic. Within the next two years, many companies seek leapfrog development, crazy expansion of production capacity and to the rest of the enclosure. Cash flow and a slight recovery of receivables and other issues directly lead to capital chain rupture, or bankruptcy, or direct collapse. Because of competitive differentiation, product price began to stabilize, various types of customized, personalized service and ancillary services from different indicators and services to meet the needs of market segments.

Full-color LED display core components related to components, IC drivers, hardware structure, control system, intelligent management system. At the same time, component manufacturers to respond positively to the requirements of display manufacturers, LED components getting smaller and smaller, the 2014 indoor display mainstream specifications are P2, P2.5, P3, P5 and so on. 2015 mainstream specifications P1.6 ~ P4. Other technical requirements at the same time bring closely with the relevant manufacturers.

Many companies began to transition from product manufacturers service operations, monitor the new business direction and leasing operations and other advertising content and increase the value of growth after corporate restructuring. But also enhance the comprehensive competitiveness of enterprises. Full-color LED display manufacturers quickly perceived demand characteristics applications, the product as a platform, companies can integrate resources such as capital, media advertising, dissemination of content and other markets, the upgrade from pure manufacturing to manufacturing services operations. Enhance the overall profitability of enterprises.

Due to the technical LED display is completely transparent for harsh indoor installation requirements, will form a new alternative market in recent years. Traditional DLP projector market traditional hotel, the venue, the exhibition, the control center and other major applications, LCD panel mosaic screen will be a large-scale transparent LED display instead. You can meet all kinds of the demanding studio, control center, control room and meeting rooms and other military, aerospace, media, exhibition, hotel, and other applications.

The LED display used in most places on the market today is probably the malls, hotels, schools, and other relevant units. Depending on the display of information, the use of LED display is also different, it can be said that LED dance floor has developed more mature.

Community Media

The next few years, with a further decline in the technology matures and prices, LED display applications in community media will be more and more. From the advertising value, the LED display is community service platform for the dissemination of information.

The China LED display industry will mature

After years of development, LED display brightness, energy, color, play mode and other aspects of the increasingly perfect, more and more loved and recognized by the market, market demand increasingly higher, LED market, a thriving scene. At the same time as the LED display manufacturers increasingly focus on the development and application of technology products. We hope to give users a better experience and to enhance the competitiveness of their products.

The data show that China LED display prices continue to decline in 2011 year on year decline of 15% -20%. The reason is to have the strength of the larger vendors want to adjust the price in the form through the integration of markets, regulate the market. Now LED display industry has entered a period of consolidation, the next few years will gradually appear some small and medium scale enterprises are merged or eliminated. In the consolidation phase, technical support and capital strength LED display manufacturers are expected to borrow the power of technology and the enterprise itself and channel advantages of the capital market to achieve rapid development. Next 2--3 years, LED display industry concentration will rapidly increase.

The led display industry is about to enter the mature stage, so the market will maintain steady growth. LED electronic display applications become broader, economic recovery, 2015 will be an LED display technology and the market have matured year.

When the switch S is closed, the free electrons of the capacitor anode LED display panel will be attracted to the power supply, and pushed to the negative plate above. Because the distance between the two plates of the capacitor with an insulating material so from the positive plate ran free electron will pile up on top of the negative electrode plate. The positive electrode plate by electron reductions will bring positive and negative plates will gradually add due to electron and a negative charge.

LED display between the two plates of the capacitor will have a potential difference when the potential difference between the power supply voltage is equal to the charge on the capacitor is stopped. If power is cut off at the moment, can still adhere to the charging voltage of the capacitor. He has been charged capacitor, if we use the wire to connect the two plates together, because between the plates presence of potential difference, electrons through a wire will return to the positive electrode plate until the potential difference between the plates is zero.

LED display higher the frequency of the capacitor, the alternating current blocking effect is reduced, i.e. small capacitance, contrary to the capacitor capacitance generated low-frequency alternating large. On the same frequency alternating current electricity. LED display capacity of the capacitor, the smaller the capacitance, the smaller the capacity, the greater the capacitance.

Due to fierce price war competition, much SMEs profits in low-profit status, and the prevalence of the back section difficult problem, China LED display industry still has many problems. In addition, last year the State Council to resolve the difficulties in financing the real economy has taken many measures, but the situation of enterprises reflect the situation, funding constraints, the financing problem has not been alleviated. In particular, some banks to adopt "one size fits all" approach, and constantly pumping loans, loans pressure, to enable enterprises to fund is very tight, and even some companies facing operational risks.

In 2014, many indoor LED displays in China show the presence of the main outstanding issues in the industry. The LED display can provide perfect solutions for indoor or outdoor high-end rental applications, such as concert tours, TV studios, business meetings, shopping mall and so on.

The rapid development of high-density LED screen products are including the LED chips, packaging, materials, processes, controls, and other technical areas of highly integrated innovative products, require collaborative innovation in all aspects of the industry chain, in order to promote the upgrading of the level of industrialization.

LED display life is generally about five years. In the past five years, can be said that China LED display the most golden years, LED display advertising in various application areas, stage, sports stadiums, etc. have been greatly popular. So in the coming years, there will be a large number of its useful life of the LED display need to be replaced, which will undoubtedly bring huge economic benefits to the enterprise. Secondly, new technologies, new products form an alternative to traditional products. Today, the industry there are three trends worth companies concerned.

In the LED screen market, LED full color display has become the market mainstream products, but to the first door panel as the representative of the LED screen market, still dominated by a single color products. But as technology advances and costs decline as a last line of defense of the single-color products door panel market, is about to be compromised, full-color LED display. In fact, back in 2011, there are companies began producing P20 full color door panel, there appeared a more sophisticated P16 products later, but because the spacing is too large for ordinary storefront display is very harsh, with costs higher, to promote them there is a big difficulty.

In 2013, single-color market share in the forefront of a strong giant color P13.3 begin pushing the main door of the first full-color screen, relying on its own strong Distribution channel capacity in the terminal market has made certain achievements. But objectively speaking, the current full-color door panel has not been able to really shake the single-color position in the door panel market, first, because the price is high, the second is not as good as a single color using simple, post-factory maintenance cost is relatively large.

We found that even the first international brand of the same file there is a large LED wavelength deviation and color saturation deviation, and the deviation range of considerably more than the human eye to green color discrimination thresholds. Thus, chroma uniformity correction is important Meaning

Need to see the control software itself, the current outdoor LED display control software has the system control software (outdoor LED screen broadcasts the software), outdoor LED display presentation software, outdoor LED display test software, outdoor LED display auxiliary software.

For system control software, most are not universal. This is because such software is to work with the hardware system, for different hardware interface is different, so basically there is no common software. For the outdoor LED display presentation software, most are generic.

For the outdoor LED display test software and support software and some common, there is not, as the software is concerned. The outdoor LED display supporting software combined with the practical application of the majority of places, such as self-developed advertising system, content display software.
