Interpretation of the way to develop an international LED display
Edit：Admin Browse： Date：2014/6/18
Exports , internationalization is often considered a high-end atmosphere on the grade thing. History of LED display products exports has more than ten years , and provides a number of global manufacturing up more than 80% , various data show that China's LED display products have already entered the international perspective, countries around the world in review . However , it is worth noting that exports are numerous, but truly their own brands and products export business has few, therefore , to explore the road of international LED display not only the maintenance requirements and, more importantly is the need to enhance the quality .
Export advantage
Cost advantage
Since the birth of full-color display , LED display industry development of China's ever-changing . According to the China Optics and Optoelectronics Manufactures Association LED display applications branch statistics, in 2012 China's LED display application market annual sales reached 25.3 billion yuan , compared with 2011 increased by 15 %. Rapid development of the industry has spawned a mature , complete industrial chain , and stimulate the production of domestic momentum . Both the size and practitioners from industry , the development of China's LED display industry matured .
Meanwhile, China's basic national conditions display products cost advantage , while China is a populous country , labor costs are significantly lower than other countries, on the other hand , letting the status quo of manufacturing greatly reduced manufacturing costs . According to statistics, China 's foreign average wage is about seven times , assuming other costs remain unchanged , only one labor costs , the overall cost of the country will display 17% lower than in other countries . The empty box, steel frame , PCB boards and other products have a larger gap between domestic and foreign price , plus the cost of the overall design , considering the domestic cost of production is about 30 % -50 % of foreign products . In addition, the export tax rebate rate of full-color LED display products applicable since December 2008 by a 13 % to 14% since June 2009 from 14% upwards to 17% again. The fact that low-cost greatly improve the competitiveness of domestic products.
In addition, the use of domestic lamp beads sharply down the costs. Costs from the constitution of the domestic LED display , which accounted for the largest LED lamp beads . While domestic enterprises are using domestic display LED lamp beads, or self- encapsulated LED lamp beads , and Barco, Daktronics and other foreign companies to use more international manufacturers ( Nichia , Cree ) lamp beads . Data show that domestic LED lamp price is about international manufacturers of 1/3, and therefore , the display cost advantage is obvious.
Technological development
Currently, the domestic LED display technology level has been roughly equal. LED display devices and key components of the core technology continues to improve in recent years , technological advances in LED display provides important technical support.
LED chip luminous intensity and luminous efficiency rising , the reverse leakage current to get better control , antistatic capabilities further enhanced, long plagued LED display electrostatic damage problem to crack . Switching power supply is a key component of the LED display , along with the industry of clean power and electromagnetic compatibility awareness , active power factor compensation (PFC) has gradually been widely applied , the switching power supply applications with high conversion efficiency synchronous rectification ( SR) is also expected to gain popularity in the industry . Driver IC , the energy-efficient low dropout driver chip , support for multi-tasking time- scan driver chips , reduces ghost precharge FET type driver IC chip greatly improves the visual performance of the display, and expanded the application prospects of the display. Control technology , 19bit products have entered the engineering applications ; brightness uniformity correction module from the early uniformity correction , a decade ago by point uniformity correction , to today through image processing methods caused due to poor mechanical assembly bright lines and dark lines for visual correction , LED display brightness correction of various control techniques almost nothing less. Driver refresh , with the improvement of the semiconductor chip running speed drive and drive continuous improvement refresh mode , LED display can now be achieved without blinking at the camera , no retrace lines , water ripples .
LED display technology brings innovation continues to introduce new forms of applications , it also brings to enhance the overall technical level of China's LED display industry. Technically speaking , China's manufacturing LED display is fully capable , strong meets the requirements of high-end display technology, an important reason for the international arena thanks to the development of technology .
The vast overseas market
LED display wide range of applications in the world, forming a broad market. 2010 -2014 global full-color LED display market will remain 30.43% compound annual growth rate is expected to market size in 2014 will increase to $ 9.55 billion .
In addition , the export of LED display space of about 60 billion yuan is also sufficient to support the rapid development of enterprises. From the perspective of the geographical distribution of overseas markets , China's largest export area LED displays are mainly distributed in Europe, Japan and Southeast Asia , the BRIC countries ( Russia, India , South Africa and Brazil ) are also important export regions.
