LED TV is expected to universal energy efficiency standards

At the beginning of March, China Institute of standardization news shows, "flat-panel TVs limited values of energy efficiency and energy efficiency rating" mandatory national standard or will be introduced in the near future. By then, the effectiveness of flat-panel TVs will be divided into three levels, one of the most energy-efficient, while the market access threshold for the level three.

It is understood that the standard in June last year has been approved, the original plan in full implementation at the beginning of this year, but eventually postponed due to various reasons. Insiders estimate that after the introduction of the standard market will have 20% high energy consuming products are eliminated, and relatively more energy-efficient LED backlight LCD TV market will be stimulated.

Flat-panel TV concept of energy is still vague

The 3C stores in North Huaqiang, flat-panel TV after "blue", "Internet" speculation turns, "low carbon energy" has gradually become one of the major TV manufacturers pushing the main selling point. Daily economic news reporter saw a lot of color TV promotional leaflets marked on the significant position of the words. Suning Appliance, a salesman of a large brand counters, said: our products have a number of patented energy-saving technology, from the screen, chips and power systems, such as a full range of energy-saving. "

In fact, whether it is really difficult for consumers to make a judgment, the only objective indicators can be used as a reference only rated power. For example, the brand of a 32 inch LCD TV, the nominal power consumption of 150 watts, but another brand of the same size of the product, but not more than 120 watts. Who is more energy saving?

LGDisplay, who worked in the electronics engineer Yu Tao said: "now the label is rated power, which is the maximum energy consumption of electrical appliances rather than the actual value. TV in the display of different images, the energy consumption is not the same, so the energy can not be simply to determine the nominal power, but through a lot of experiments and calculations. "

High energy consumption is facing elimination of color TV

Introduction of the introduction of flat-panel TV energy standards, the market is expected to change the concept of the current situation of fuzzy energy-saving. It is understood that this standard provides for flat-panel TV energy efficiency rating, energy efficiency limit value, energy conservation evaluation, measurement methods and inspection rules, etc.. Before the listing, we must do a series of experiments according to this standard to get the actual energy saving effect.

Zhang Xinceng, an engineer at the China Institute of standardization, said that energy efficiency limits would be mandatory, and that only two or more of these could be identified as energy efficient products. The three level is the level of market access, mainly in order to eliminate the current high energy consuming products on the market. After the introduction of the standard, currently accounts for 20% of the market's inefficient products will be eliminated.

It is understood that at the end of 2009 Chinese Standardization Research Institute has conducted a sample survey of flat-panel TV market, all products have reached the three standards of energy efficiency rating requirements, but most were in grade two or grade three, reached the level of energy efficiency is not much.

Energy saving standards to promote the popularity of LED TV

In fact, the manufacturers of the standard is placed a greater expectations, because the standard on the one hand to make the market more standardized, on the other hand can also promote technological upgrading and expansion of the market. Shenzhen SKYWORTH marketing department head Liang Zhong said: we have been in the early popularity of energy-saving products, but also do a lot of publicity, especially LED backlight LCD tv. "

He said: at present, the proportion of SKYWORTH's LED products have accounted for 20%, this year is expected to increase to 30%. "And the biggest advantage of L E D is energy saving. After our actual estimates, a 42 inch LED TV average energy consumption of 110 watts, compared to traditional LCD TV energy saving more than 45%. Liang Zhong stressed that although this is not attractive for consumers in the first tier cities, but the electricity sensitive two or three tier cities and the rural market is concerned. Because the average life expectancy of about 7 years, if you can save hundreds of dollars per year of electricity, it is equivalent to save a tv. "

In addition, the industry sources, the introduction of the standard and the introduction of the country's energy-saving product subsidies are not unrelated. Because air conditioning has now been implemented subsidies, but flat-panel TVs are faced with subsidies can not be the embarrassment, the direct reason is that there is no set of criteria to distinguish which is energy-saving products. After the introduction of the standard, whether consumers or manufacturers are beneficiaries.

Energy efficiency standards

After 2012, consistent with international practice

LCD and plasma are flat panel TV, but the calculation of energy consumption is not the same. It is understood that the LCD TV 3 levels of energy efficiency index were 1.4, 1 and 0.6, while the plasma TV was respectively 1.2, 1 and 0.6., in addition, in addition to the standard of evaluation will be conducted on energy efficiency, further defines specific requirements for standby power, before January 1, 2012, less than 1 watts; after January 1, 2012 is not greater than 0.50 watts consistent with international practice.
