The market for sapphire single crystal wafers is in short supply, and the average unit price is increasing every quarter. Zhaojing Technology's profit per share in the first eight months of this year was as high as 4.59 yuan, the highest in the calendar year. By the end of this year, the company's production capacity will continue to expand. Increased, the estimated monthly production capacity will increase from the current 240,000 to 300,000, an increase of 25%.
Zhaojing produces 2å‹ LED sapphire single crystal wafers, which belongs to the middle of the LED industry. Zhaojing said that LEDs used to account for about 45% of mobile phones in the past, followed by displays, vehicles, etc., but since the financial tsunami in 2008, LEDs are used in the two markets of consumer electronics and Minsheng Lighting.
After South Korea's Samsung Electronics fully invested in LED-backlit LCD TVs, data is currently known to show that in 2010, LED backlights in the global LCD TV penetration rate have been revised up to more than 35%; notebook computer backlights, more than 90%, The predicted value has been greatly exceeded. Therefore, since the second half of 2009, high-brightness blue-ray crystals have been reported to be out of stock, causing large companies such as Samsung, LG, and Seoul Semiconductors to make huge investments. Vertical integration of LED production lines in an attempt to control the stable source. LED manufacturers in Taiwan, China and Japan have also snapped up related equipment and raw materials to form an investment boom in the industry.
According to internal statistics, since the second half of 2009, LED epitaxial wafer plants have significantly expanded their production capacity. At the end of 2009, the global monthly demand (2 miles equivalent) was already 1 million pieces, which is close to the time. Global sapphire crystal growth total capacity. In 2010, the epitaxial plant accelerated the expansion rate. It is estimated that the demand equivalent of 2 million months at the end of the year will be about 1.8 million pieces, and at the end of 2011, it will reach more than 2.5 million pieces. In 2012, it will exceed 3 million pieces. In just three years, demand will increase by three times. Such an amazing growth rate, even if the wafer processing capacity can be supported, the growth rate of Changjing will be severely short due to the expansion of production, and even the price increase. Zhaojing pointed out that the current market can produce sapphire single crystal wafers, which failed to meet the demand, resulting in a quarterly increase in selling price. The company is also actively expanding its new capacity, and in terms of orders, Rongjing can be prosperous. By the end of the year.
Battery is the energy source of AGV car, and also relates to the service life of AGV car.Common battery types for AGV vehicles include nickel-cadmium battery, nickel-metal hydride battery, lithium battery and lead-acid battery, which have the following characteristics:
The nickel-cadmium battery used in AGV car has large internal resistance and can be used for large current discharge.
2. Nimh battery
It offers higher capacity at the same price as nickel-cadmium batteries, less pronounced memory effects, and lower environmental pollution.
3. Lithium battery
"Lithium battery" is a kind of battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. Because lithium battery has the characteristics of high energy density, high voltage and stable operation, it is widely used.
4, lead acid battery
The electrodes are mainly made of lead and its oxides, and the electrolyte is a kind of battery with sulfuric acid solution.Lead-acid battery has the advantages of good invertibility, stable voltage characteristics, long service life, wide application range, abundant raw materials, renewable use and low cost.
