China is preparing to issue energy efficiency standards for flat-panel TVs

recently, it was learned that China's energy efficiency standards for flat-panel TVs are being formulated. At the same time, the European Union announced its plan to adopt the minimum energy consumption standard for TV sets this spring, and the British government also stated that it would issue a regulation banning the sale of high energy consumption plasma TVs this year

the lack of standards leads to a wide gap in energy conservation.

Zhao Xinhua, assistant director of the China Institute of electronic technology standardization, said that the energy-saving technology of flat-panel TVs has been developing continuously. Compared with the initial stage of China's flat-panel TV consumption market in 2003, the current flat-panel TVs have been greatly improved in energy consumption. In the early days, the power consumption of a 32 inch LCD TV was basically 180-200 watts. Now it can generally achieve 110 watts, reducing energy consumption by more than 38%. The improvement of energy-saving effect of flat-panel TV not only contributes to social economy, but also brings certain benefits to consumers

however, the energy consumption level of flat-panel TVs of various brands is uneven. A special test study on the energy consumption of flat-panel TVs by the consumer electronics Survey Office of the China electronics chamber of Commerce found that guostacy Edinger suspected that the government would not agree to suspend the imposition of tariffs on flat-panel TVs of different sizes and specifications, and the overall power consumption level was uneven, with 46 inch or 47 inch LCD TVs being the most prominent. The maximum power consumption of such products was 289 watts, and the minimum was 171 watts, with a difference of 118 watts, The difference is 40%

Dr. zhangsubing of China Institute of electronic technology standardization said that at present, enterprises have carried out the research, development and production of flat-panel TVs with the theme of green and environmental protection. Enterprises actively develop products with the concept of energy conservation and environmental protection, which has been widely recognized by domestic consumers. However, due to the lack of standards, in recent years, not only the production and publicity of enterprises are lack of measurement criteria, energy consumption has even become a weapon for enterprises to attack each other

The formulation of the standard was hindered by the "average brightness"

Chen Haihong, a senior engineer of the Institute of resource and environmental standardization of the China Institute of standardization, said that the draft of the national mandatory energy efficiency standard - "limited values and energy efficiency grades of flat panel TV" was originally planned to be issued at the end of 2008, but due to differences of opinion, it is still under discussion

it is reported that the focus of the post selection debate is on the calculation method of energy consumption indicators in the standard. The "average brightness" is introduced into the calculation of the energy efficiency of flat-panel TVs, the most important core indicator in the draft standard of driving 100000 people to work. Yang Xiyang, director of the plasma Professional Committee of China Electronics and video industry association, said that there is no index of "average brightness" in the calculation formula of IEC flat panel TV international standard. This index may enable flat panel TVs to adopt the brightening film technology involving upstream patents in the production process. Some manufacturers may simply increase the average brightness by pasting brightening film without changing the power consumption of flat panel TVs. In this way, The national energy efficiency standard of flat panel TV has lost the significance of energy conservation. At the same time, Yang Xiyang believes that China is a big exporter of color TV sets. If there is a big difference between the standards and international standards, it will be detrimental to the development of the industry

in addition, the industry standard "plasma energy consumption standard" planned to be released in December 2008 also ran aground due to differences between the test method and the national standard. Yang Xiyang said that at present, all parties are actively taking actions to reach an agreement, so as to make the standards available as soon as possible

Yu Wei, director of the Department of energy conservation and comprehensive utilization of the Ministry of industry and information technology, said that the country's macro promotion of building a resource-saving and environment-friendly society has brought opportunities for the development of green industries. Starting from energy-saving air conditioners, green refrigerators, water-saving washing machines, to reducing the power consumption of large screen flat-panel TVs, it is comprehensively driving the household appliance industry to transform to low-energy, environmentally friendly products
