DisplaySearch analysts see a recovery in the market for LCD TVs. In 2010 not only the number of TVs sold in 2009 to climb, and revenue there will be growth. The experts predict Quarterly Global TV Shipment and Forecast report.

Already in the third quarter of 2009 increased the sales of LCD televisions ԤC for the first time in a year. Because of this upward movement, the analysts suggest that sales in the first quarter of 2010 could be better than in the first quarter of 2009. That would be the first increase in six quarters.

The sales of TV sets is expected to rise, according to DisplaySearch 2010 by six percent to 218 million units. 2009 there were 205 million. But 170 million LCD TVs next year would go over the counter, compared 140.5 million this year.

Using two-cell

With the portable system design complexity increase, they use the subsystems, displays, and the number and type of processors are more and more, single-cell lithium-ion batteries have been unable to meet system needs. Therefore, some portable media players, high-performance SLR digital camera and GPS navigation systems are beginning to use series of two lithium-ion battery. These portable products are generally asked to enter in the 8.4V and 8.8V charging between. Designers are using discrete devices previously achieved this design, but will support this demand has started a new generation charger chip market.

Typical example is the AT3663, which is Advanced Analogic Technologies Inc. (AnalogicTech) 1A linear battery charger provided the first product series chips can be used for up to two series of lithium-ion batteries. AT3663 by the manufacturer's proprietary Modular BCD process technology. This technology integrates fully isolated CMOS and high-speed complementary bipolar transistors and 30V DMOS power devices without using complex and expensive extension of epiphytic or high temperature diffusion technology.

The new process allows the AAT3663 supports from 4V to 13.2V input voltage, so designers are free to use the lower cost of non-regulated adapter.

Sony will equip its being developed new games console Playstation 4 may stop with a Cell processor. According to press reports, the manufacturer is currently looking for alternatives.

Besides highly modernized versions IBM Cell Power-7-CPU, x86 processors are based on Sandy Bridge or the failure of a discrete graphics card Larrabee architecture in question.

Integrators of popular high-end graphics cards have, in recent years, which approximated a Cell processor. In particular, the possibility is stressed to handle floating point numbers with double precision (64 bit) - a skill that is not needed for 3D graphics.

Multiple voltage source

One increasingly common request is from a different source to recharge the battery voltage, point is not to voltage source in case of overload to provide this function. Changes in input conditions can be dynamically adjusted when the charge current to achieve this functionality.

For example, mobile users often do not have time to find the AC outlet to recharge their equipment to the contrary, they hope that most of the many electronic devices have a USB port to charge the battery to them, including other battery-powered devices such as laptops. Therefore, the current market, many of the charger chip supports USB communication and input from a single lithium battery charge. At this time the challenge is to provide compensation for the changing USB port power level. As the load changes, the system must control the value of a constant charging current to ensure the normal operation of USB ports.

Some charger chip dual approach supports the use of simple USB operation, the method uses two preset charge current value (usually 500mA and 100mA) to support the USB port to allow the maximum current or the minimum current necessary to ensure the integrity of the port sex. Usually this requires interface logic embedded in the charger chip, so that the system microcontroller can read the USB port on a continuous state, and indicates a charging current from the charger to switch to another charge current.

Unpredictable future of hydrogen fuel-thinkpad t400 battery , thinkpad t500 battery , thinkpad t40 battery , etc.

March 2007, a "development vehicle power technology, so as to ease traffic pressure on the recommendations of energy" (the "Proposal") written by the expert group and a petition, sent to the relevant departments. "Hydrogen fuel cell vehicles prospects for the future, there are many unpredictable factors. If the hydrogen fuel car of the end, need to go find other technical means, which makes large-scale investment in hydrogen fuel car naught." 26 experts advise If China blindly follow the pace of some multinational companies, a large number of financial, human and material resources fully, "bet" in the hydrogen vehicle research and development, is likely to give as a pillar industry of China's auto industry has brought great harm.

"Supporting this letter is much more than 26 people." Expert who asked not to be named, said the "863 plan, to focus public attention to new energy sources such as hydrogen fuel cars, the government sector-oriented Many car companies to bring pressure and power, many companies regardless of their blind pursuit of power and new energy is very dangerous. "

Hydrogen fuel cell research began in the United States. April 2005, General Motors and Daimler - Chrysler Corporation signed a contract with the U.S. Department of Energy in the next 5 years, hydrogen fuel cell electric vehicle development. A time of "hydrogen energy" concept overwhelming, "hydrogen energy" slogan but also across the oceans to China.

According to these experts say, the so-called "hydrogen energy" is actually using other energy to convert water into hydrogen, then hydrogen as a fuel is converted to power through fuel cells, this process does not "overflow" any "could," " Hydrogen Energy "is actually" hydrogen fuel. "

Coupled with the high cost of fuel cells can not be mass-produced the battery capacity is too small long-distance travel difficult. If these long-term can not be overcome technical difficulties ultimately failed to conquer, then even 100 years after the fuel cell vehicles or electric vehicles will not become mainstream vehicles.

The expert explained that the reason of "hydrogen energy" slogan instead of "hydrogen fuel", the key is to make this concept a lot of people mistakenly think that the use of hydrogen energy could solve the traffic problem, so no matter the banner of "hydrogen energy" under the banner of what to do matter how many R & D resources, spending billions of money are the things should be.

Hydrogen Energy - the future "clean" power?

For China's car manufacturers, there is nothing more important than the control engine technology for doing this. On the one hand, the domestic auto industry active digestion and absorption of foreign advanced production technology gasoline engines, while money in developing new energy when the engine, a conventional engine by 26 domestic and foreign experts questioned the State Council jointly submitted "hydrogen" technical outlook has exposed the letter. Recommendation letter written much: China is a major energy consumer, but not a lot of oil and gas resources.

China's oil imports in 2005 accounted for 42.9%. Dependence on imported oil to China's economic development and national security restriction. As soon as possible to reduce dependence on imported oil, should be targeted for development of vehicle power technology. To this end, we are first in domestic vehicle power technology development are some problems, namely "seeking Yuan Lai solution of water near thirst", "first dug drainage water or Deng to find water," the such circumstances and to its analyzed. Then, put forward as soon as possible through the technology development to reduce pressure on transport energy proposals. Currently, the "hydrogen energy" to bring awareness of the deviation of misunderstanding, thus affecting energy policy to solve the traffic.

Energy is that people get energy from natural sources, nature does not exist a large number of hydrogen, so hydrogen is not energy, but not new energy. Need to produce hydrogen energy conversion, so the hydrogen can be used as energy carrier. "Hydrogen Energy" slogan so many people think that the use of hydrogen energy will solve the traffic problem, it is natural to assume that the development should concentrate on full hydrogen cars. This misunderstanding will affect the government and enterprises to solve the traffic problems of energy policy. As a heavy bomb, the letter in the academic and automotive industry has created a stir, a heated debate and it has started.
