April 20, Jing Sheng Electrical released announcement about 100,000 per month sapphire cutting and grinding and polishing project feasibility analysis. The project is 100,000 per month sapphire cutting and grinding and polishing, by the Zhejiang Jing Sheng Electrical Co., Ltd. (hereinafter referred to as "Jing Sheng Electrical" or the "Company") construction, mainly produces LED sapphire wafer, put into operation can achieve an annual output of 1.2 million 2-inch sapphire wafer.

Foreign-funded enterprises have been aware of the ills of the transition depends Gome, Suning chain channel, Korean companies - LG Electronics will force e-commerce in China this year. Du Hwa, general manager of LG Electronics South China Region, said that this year, LG started by line development to online e-commerce transactions. In addition, due to the demand for rural urbanization larger, and tertiary markets, the growth rate is much higher than a secondary market, LG plans to product penetration in secondary and tertiary markets.

In addition, in the next-generation display technology OLED product launches of outside attention, LG 55-inch OLED TV program was launched in Beijing in May 2013, Du Hwa said. Du Hwa pointed out that one of the LG strategic core is take China as a strategic market. "The latest, most high-end products put on the Chinese market, through the organization, channels to increase coverage."

April 18, the reporter learned from the Shenzhen Urban Management Bureau, Shenzhen road 31 LED display upcoming "induction", in the event of typhoons and storms and other emergencies, the LED screen will be released within 2 hours early warning, the rise of the publicvisible emergency information.

LED screen as of yesterday, there are 20 companies a total of 31 display a written application in the form of the report, expressed its willingness to play early warning and emergency information free of charge on the LED screen. Urban Management Bureau of Shenzhen city management at the relevant person in charge told reporters that the Shenzhen relevant laws and regulations to force LED screen playback emergency response information, there are certain difficulties in this work is in full swing, so take to encourage LED screen companies to voluntarily sign up.

In early April, members of the public living in the vicinity of Shenzhen Futian "the Galaxy Century" and Nanshan Coastal City LED screen has been some new changes, the LED screen there have been many Tips from time to time play the "flood season approaching, all unitsdo a good job ready "message. Shenzhen Urban Management Bureau official told reporters that this is the Shenzhen LED screen a few pilot panel warning emergency information, test results are very good. By the Shenzhen Municipal Emergency Management Office and Meteorological Observatory has formulated and promulgated the size and style of the early warning and emergency information 31 LED screen upcoming posts.

This reporter learned that Shenzhen will rely on urban management and supervision and command center 24-hour operation, "seamless" with the City Emergency Management Office and Meteorological Observatory, to publish early warning and emergency information, real-time notification LED screen enterprise, Shenzhen road within 2 hoursthe major LED screen that emergency information.

It is reported that the Shenzhen Urban Management Bureau will sign an agreement with 20 LED screen enterprise authorized 31 LED screen legitimate play and early warning information. The near future, will be published in the Shenzhen Urban Management Bureau website 20 companies 31 LED screen name and lots of location, and enterprise directory feedback to the Shenzhen City Emergency Management Office and Meteorological Observatory.

Recently, scientists from the University of Illinois invented a miniature LED the tiny can easily through the tiny eye of a needle. The experiment proved that the micro-LED wireless operation, effective deep brain stimulation, nervous system diseases, such as movement disorders, have a certain effect.

In the experiment, the researchers will be an LED probe into the brains of mice, and then, by using light pulses to stimulate the neurons on the part of the rat brain reward pathways. Mice the LED pulse stimulation, they will spend more time in the Y-shaped maze, if they know how to get in the maze food reward.

John Rogers, one of the experimental leader, said that this new micro-LED will be able to effectively improve the treatment of neurological diseases, accurate embedded LED light source for medical personnel, sensors and other medical components into the patient's brain play a great help. If the research is completely successful and popular, this miniature LED medical equipment will be able to cure the movement disorders, including neurological diseases.

Recently, the World Bank funds, mining Wo International Group Epson low-carbon Technology (Beijing) Co., Ltd. co-sponsored by China LED optoelectronic 10 billion industry fund was established in Beijing.

The first quarter of 2013 Kunshan Kunshan Inspection and Quarantine Bureau of Statistics, total exports of 674 batches of LED lamps, the amount of $ 37,150,000, an increase of 12.5% ​​and 36.4%.Mainly exported to Japan, Germany, the United States and Southeast Asia and other countries and regions.

In recent years, an important part of the six strategic emerging industries, Jiaxing, Zhejiang LED industry from scratch, from point to plane, extend the industrial chain constantly growing industrial scale, and has formed a covering sapphire substrate, chip manufacturingdevice package, product application link is relatively complete industrial chain.

Blue sapphires are evaluated based upon the purity of their primary hue. Purple, violet, and green are the most common secondary hues found in blue sapphires. Blue sapphires with up to 15% violet or purple are generally said to be of fine quality. Blue sapphires with any amount of green as a secondary hue are not considered to be fine quality. Gray is the normal saturation modifier or mask found in blue sapphires. Gray reduces the saturation or brightness of the hue and therefore, has a distinctly negative effect.
The color of fine blue sapphires may be described as a vivid medium dark violet to purplish blue where the primary blue hue is at least 85% and the secondary hue no more than 15%, without the least admixture of a green secondary hue or a gray mask.

Thin sapphire wafers also are used as an insulating substrate in high-power, high-frequency CMOS integrated circuits. This type of IC is called a silicon on sapphire or "SOS" chip. These are especially useful for high-power radio-frequency (RF) applications such as those found in cellular telephones, police car and fire truck radios, and satellite communication systems. "SOS" allows for the monolithic integration of both digital and analog circuitry all on one IC chip.
The reason for choosing wafers of artificial sapphire, rather than some other substance, for these substrates is that sapphire has a quite low conductivity for electricity, but a much-higher conductivity for heat. Thus, sapphire provides good electrical insulation, while at the same time doing a good job at helping to conduct away the significant heat that is generated in all operating integrated circuits.

Once the single crystal sapphire boules are grown they are cored-sliced into cylindrical pieces. Wafers are then sliced from these cylindrical cores. These wafers of single-crystal sapphire material are also used in the semiconductor industry as a non-conducting substrate for the growth of devices based on gallium nitride (GaN). The use of the sapphire material significantly reduces the cost, because this has about one-seventh the cost of germanium. Gallium nitride on sapphire is commonly used in blue light-emitting diodes (LEDs).
