LCD TVs will overcome the crisis in 2010 A

The analysts at DisplaySearch expect higher 2010 sales and revenues. The conversion to digital TV boosts demand. LED backlight and 3D TV to give additional impetus.

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 – 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.

Recently, some charger chip maker has developed a USB port can automatically detect the available power, and to adjust the charge current to maximize charging efficiency of the chip. In addition, many charger chip does not require user intervention, it can automatically detect power | voltage regulator type and adjust their charging process.

When Linear Technology's LTC4075 battery charger chip to detect when the input power, it automatically selects the appropriate power to charge, and no external MOSFET, sense resistor or blocking diode.

Microchip Technology's MCP73837 companies also offer similar automatic power options.

As possible alternatives POWER7, Sandy Bridge and Larrabee processors are traded. The Cell processor can not keep up with the performance of modern graphics cards.

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.
