The development of led display has been two levels of differentiation. Looking at the overall situation of the LED display industry, it is clear that the 2008 financial crisis has not had much impact on the LED industry. I want to anti-2008 China's LED industry as a whole has maintained a relatively good development momentum, and the status of the industry in the world continues to improve. In 2008, China's chip output value increased by 26% to reach 1.9 billion yuan; LED package output value reached 18.5 billion yuan, up 10% from 2007's 16.8 billion yuan; in 2008, China's applied product output value has exceeded 45 billion yuan, LED full color display Applications such as solar LEDs, landscape lighting, consumer electronics backlights, signals, and indications remain the main applications. Domestic functional municipal lighting has developed rapidly, and hundreds of thousands of LED demonstration application street lamps have been applied, and it is expected to form a scale soon. Some progress has also been made in LCD-TV backlights and automotive lights, but it will take some time to form an industrial scale.
In the long run, in 2009 and in the next few years, with the prevalence of global energy conservation and emission reduction, environmental protection and energy conservation have become hot spots in the market, and the LED industry has begun to heat up. After more than 30 years of development, China's LED industry has achieved independent production of devices, chips and epitaxial wafers. However, the production of self-produced LED chips and epitaxial wafers is still limited. The products are mainly medium and low-grade, and the scale of industrialization is small. It can only meet the demand of domestic packaging enterprises by 20%-30%. Most high-performance LED and power LED products depend on imports. With the government's vigorous promotion and global industrial ladder transfer, China's LED will become the most attractive cake in the market in the future. It is estimated that by 2010, the output value of the entire Chinese LED industry will exceed 150 billion yuan. In the LED industry chain, LED epitaxial wafers and LED chips account for about 70% of the industry's profits, LED packaging is about 10%-0%, LED applications are about 10%-20%. In 2015, the industrial scale reached more than 500 billion yuan. China's entry into the LED industry is increasing day by day, and the competition in the industrial market will become more intense.
Under the pressure of market competition, if the LED industry really wants to break through the bottleneck of development and master the right to speak in the market, it must have strong technical advantages and have its own independent intellectual property rights and core technologies to be able to develop its stamina. At the same time, with the funds allowed, the focus will be on the development of new products, the application and improvement of patent applications and quality systems, grasping all market opportunities that can be seized, adjusting the market and product positioning of the company, and highlighting its own Advantages, establish strategic alliances with other upstream and downstream enterprises, jointly develop and expand the city. In view of the current led economic situation, the development of China's led display industry in 2010 is still very impressive. Receive the policy influence and positive promotion of local governments and regions. China's LED display industry has huge market potential, but there is no real rise of some new rising LED display manufacturers. Due to some factors, the research and development of China's LED display industry is still insufficient. Still not many. Therefore, the author believes that the LED display industry must rise into China, it must invest in research and development and do some new innovations. In 2010, the LED display market prospects still have considerable potential. Our LED display companies can make some corresponding adjustments according to different strategies. In order to dominate the led display industry.
Incremental Encoder is commonly used, and Absolute Encoder is used if there are strict requirements on position and zero position. Servo system should be analyzed in detail, depending on the application situation. Commonly used incremental encoder for speed measurement, which can be used for infinite accumulation measurement; Absolute encoder is used for position measurement, and the position is unique (single or multiple turns). Finally, it depends on the application situation and the purpose and requirements to be realized.
