At the beginning of March, the China National Institute of Standardization had news that the mandatory national standards for "flat-panel TV energy efficiency limits and energy efficiency ratings" will be introduced in the near future. At that time, the performance of flat-panel TVs will be divided into three levels, one level is the most energy-efficient, and the third level is the market entry barrier.
It is understood that the standard has been approved in June last year, originally planned to be fully implemented at the beginning of this year, but was eventually postponed for various reasons. Some insiders estimate that 20% of high-energy-consuming products will be eliminated in the market after the introduction of the standard, and the relatively more energy-efficient LED-backlit LCD TV market will be stimulated.
Flat-panel TV energy saving concept is still blurred
In the 3C stores in Huaqiang North, after the "Blu-ray" and "Internet" round-up hype, the "low-carbon energy-saving" has gradually become one of the main selling points of major TV manufacturers. The reporter saw that many of the color TV promotional flyers marked the words of energy saving in the prominent position. A salesperson of a certain brand counter of Suning Appliance even declared: "Our products have a number of patented energy-saving technologies, which can save energy from screens, chips and power systems."
In fact, whether energy conservation is really difficult for consumers to judge, the only objective indicator that can be used as a reference is only "rated power". For example, the above-mentioned brand is a 32-inch energy-saving LCD TV with a nominal power consumption of 150 watts, but another brand of the same size, but only 120 watts. Who is more energy efficient?
Yu Taoman, an electronics engineer who worked at LGDisplay, said: "The current rating is the rated power, which is the maximum energy consumption of the appliance, not the actual value. When the TV displays different screens, the energy consumption is different, so Whether energy saving can't be determined simply by the nominal power, but through a lot of experiments and calculations."
High-energy color TV faces are being eliminated
The introduction of the energy-saving national standard for flat-panel TVs is expected to change the current state of the energy-saving concept of the market. It is understood that this standard specifies the energy efficiency rating, energy efficiency limit value, energy saving evaluation value, measurement method and inspection rules of flat panel TV. Before the TV is listed, it is necessary to do a series of experimental tests according to this set of standards to obtain the actual energy-saving effect, and label it so that the consumers can see at a glance.
Zhang Xin, an engineer at the China National Institute of Standardization, one of the standard-setting units, said that the energy efficiency limit will be a mandatory indicator, and only two or more levels can be recognized as energy-saving products. The third level is the level of market access, mainly to eliminate the high energy-consuming products currently on the market. After the introduction of the standard, the low-efficiency products currently occupying 20% ​​of the market will be eliminated.
It is understood that at the end of 2009, China National Institute of Standardization conducted a sample survey on flat-panel TVs in the market and found that all products met the requirements of the three-level energy efficiency rating specified by the standard, but most of them are concentrated at the second or third level. There are not many energy-efficient ones.
Energy-saving standards promote the popularity of LED TV
In fact, manufacturers place great expectations on standards, because standards on the one hand make the market more standardized, on the other hand, it can also promote technology upgrading and market expansion. Liang Zhong, head of Shenzhen Skyworth Marketing Department, said: "We have already popularized energy-saving products in the early stage, and we have also done a lot of publicity work, especially LED-backlit LCD TVs."
He said: "At present, Skyworth's LED products have already accounted for 20%, and this year is expected to increase to 30%." One of the biggest advantages of LED is energy saving. “After our actual calculations, a 42-inch LED TV consumes an average of 110 watts, which is more than 45% more energy efficient than traditional LCD TVs.†Liang Zhong particularly stressed, “Although this is attractive to consumers in first-tier cities. The power will not be great, but the second- and third-tier cities and even the rural market, which are sensitive to electricity tariffs, are attracting attention. Because the average TV life is about 7 years, if you can save hundreds of dollars in electricity every year, it is equivalent to saving. A TV."
In addition, some insiders have revealed that the introduction of this standard is not unrelated to the subsidy policy for energy-saving products introduced by the state. Because air conditioners have already implemented subsidies, flat-panel TVs are faced with the shackles of subsidies that cannot be relied upon. The direct reason is that there is no set of standards to distinguish which ones are energy-saving products. After the introduction of the standard, both consumers and manufacturers are beneficiaries.
Energy efficiency standard
Consistent with international practice after 2012
Both liquid crystal and plasma are in the category of flat-panel TVs, but the calculation of energy consumption is not the same. It is understood that the energy efficiency index of the three levels of LCD TVs are 1.4, 1.0 and 0.6, respectively, while the plasma TVs are 1.2, 1.0 and 0.6 respectively. In addition, the standard will limit the standby power, in addition to the energy efficiency. For, no more than 1.0 watts before January 1, 2012; no more than 0.50 watts after January 1, 2012, in line with international practice. (Edit: Led Fish)
