Data released by the marketers, definitely indicate a decrease, both sales and production of the once popular formats, and some key brands such as Pioneer and Hitachi, in recent years have disappeared from view since then, has as consumers have opted for a more subtle, energy-efficient display format. In accordance with the annual quarterly sales figures released by retail analyst GfK, since lcd TVs continued to gain market share of plasma sales decreased by 15,4% and amounted to less than a quarter of sales of all televisions with flat ekranom.Tsifry also show that since January, total sales of plasma tv in Australia fell by almost 9%, while sales of lcd has grown an additional 10%. General Manager Bing Lee, Phil Moujaes, said that manufacturers of lcd TVs in recent years have made a significant step vpered.On said that people are buying lcd because global demand remains high for smaller screens, but if you look at the big screens, plasma is still more competitive.

"He said that the selection criterion between lcd and plasma eventually becomes the price, and that the large plasma screens are still more affordable than the large LCD-panel. Samsung, one of the three major tv manufacturers are still producing plasma screens, said that, although demand is leveled, the plasma retained much of the technology since been put into production the finest in the world of lcd screens (2,5 cm), and integrated wireless technology and internet television in the past models. "Plasma is about 25-30% of the market, which means still a very large market share", – said Evan Manolis, senior product manager of audio-visual devices from Samsung .V in the world still have a lot of people who like the look of plasma screens, juicy colors, contrast and volume of manual control.

Thus, the biggest challenge for the plasma – a desire to conserve energy, as consumers became more attentive to the environment. "We have reduced energy consumption plasma screens up to 40% compared with the 2007 model year", – said on.Plazma may lead among the big screens, but in accordance with these general production from the research group Gartner, this situation can not continue, because it is expected that lcd sales will grow at a compound annual rate of growth of 28% by 2012, compared to 8,1% plazmy.Plazma led the segment market 30-inch screens to 2003goda, but the situation changed in late 2004, when suppliers of lcd panels have launched a production line of the sixth generation. Researchers say that for screens measuring 40 inches or more lcd panels were more competitive than the plasma from the opening of the seventh generation production line in 2005. Since then, the gap between lcd and plasma gradually increased in favor of lcd. "Compatibility issues and lack of competitive impact on the plasma screens that are losing market share of large-sized TVs. The scale of the savings made lcd panels, affects the production of plasma in the form of slower growth, "- says Gartner.

Nowadays, electrical networks in all regions of Russia are obsolete and are working to the limit. The load on the network increased by several times. As a result of frequent electricity outages. High or low voltage surge, Flash off – with all this consumer is already familiar. Computers, audio-video systems, televisions, many models of home appliances with microprocessors, not only can not operate correctly, but be rendered unusable due to power anomalies.

Sudden power outages not only dangerous for your computer, but for an ordinary tv, vcr, refrigerator, etc., as tripping accompanied by a cast of current and voltage (impulse noise). Learn more about this with altavista. Many of you know firsthand about the burnt as a result of power outages technique. In many countries, to protect the power supply used stabilizers voltage, high voltage circuit breakers. Low blood pressure – the most common cause of poor power supply. The most common cause of low voltage – deficit electricity, which is especially typical for the winter months when the majority of the population includes heaters. Long-term operation technique, which has in its structure an electric motor in a low voltage leads to accelerated wear of components, and in some cases it is possible not only serious damage but fire the device.

How to protect yourself? Voltage regulators provide protection against such in power. They line the line voltage to a normal level (220 + / – 5%). Increased tension. Very often it is – a consequence of an emergency condition of the wiring in their homes. "Zero burning" occurs as a result of disconnection of the total null wire, when the neighboring phases are under a voltage of 380 V. Often dangerous high voltage occurs on the network because of incorrect switching wires. High voltage leads to irreversible consequences for the equipment. The probability of a fire. How to protect yourself? In the event of a dangerous level of the supply voltage close to 380, a voltage regulator to protect, disable the user from the emergency power supply. But if the consumer has a large Part-time voltage within the normal 220 + / -10%, there is no reason to buy an expensive surge protector. Correct to install high-voltage circuit breaker, which will ensure effective protection at low cost. In the event of a network voltages above 255 V it "soft" disconnect the load from the network. Circuit breakers are mechanical, and electronic type.
