The energy saving of flat-panel TVs is promising. Haier, Hisense, Changhong, TCL, Xoceco, Hitachi, LG, Philips, Sharp, Samsung, Panasonic, Toshiba and other 12 color TV companies have pushed “energy-saving flat-panel TVsâ€; Haier, Hisense, Changhong, TCL, Sharp and Panasonic were the first to receive CESI flat-panel TV energy-saving certification.

At this stage, large-screen flat-panel TVs are becoming more and more popular in urban households in China, and while bringing more shocking visual enjoyment to consumers' daily lives, flat-panel TV products consume too much power and consume more power. The ever-increasing cost of electricity consumption has increased the burden of consumption. Under the national “construction of resource-saving and environment-friendly society†development plan, it puts forward new challenges and requirements for energy-saving and consumption reduction of flat-panel TV products, prompting Haier, Hisense, Changhong, TCL, Philips, LG, Samsung, Hitachi. Other mainstream flat-panel TV companies continue to develop energy-saving technologies and apply them to flat-panel TV products to meet the needs of the times.
At the "2008 China Flat Panel TV Energy Consumption Test Results Release Conference" held on September 23, Lu Jianbo, a researcher in the home appliance market and deputy secretary general of the China Electronics Chamber of Commerce, pointed out that in the past, consumers have been on home appliances for a long time. The focus of energy conservation is on air conditioners, refrigerators, washing machines, etc. It is not known that the power consumption of large-screen flat-panel TVs has increased significantly compared with traditional CRT TVs. At this stage, the power consumption of large-screen flat-panel TVs has occupied an important position in daily life. Take a 42-inch ordinary LCD TV as an example. It takes about 120 hours to watch a month and consumes 30 degrees of electricity. The average consumer's household electricity consumption is 100-120 degrees per month, and the color TV power consumption accounts for 30%. According to the survey data of the Consumer Electronics Research Office of the China Electronics Chamber of Commerce, by the end of 2008, the number of flat-panel TVs in China's urban households will exceed 25 million units, and the power consumption of flat-panel TVs will be reduced by 10W, which means that 360 million kWh of electricity can be saved every year. This can basically meet the daily electricity consumption of a medium-sized city with a population of one million. Test data shows that in the current 32-inch LCD TV with the highest penetration rate, the lowest power consumption of the whole machine is 85 watts, which is 30 watts lower than the average level of 32-inch LCD TV industry, and promotes the use of corresponding energy-saving technologies. It can save the electricity consumption of three medium-sized cities throughout the year, and the energy saving of flat-panel TVs is very good.
Director of the Department of Energy and Comprehensive Utilization of the Ministry of Industry and Information Technology, Mr. Yu Wei said that the country’s macro-pushing of “building a resource-conserving and environment-friendly society†has brought development opportunities to the green industry, and the water, electricity, and Gas and other energy consumption prices, so that consumers began to pay more attention to the life, from energy-saving air conditioners, green refrigerators, water-saving washing machines, to reducing the power consumption of large-screen flat-panel TVs, is driving the household appliance industry to low energy consumption, environmental protection Product transformation.
Zhao Xinhua, secretary general of the National Audio Video Standardization Technical Committee, said that the energy-saving technology of flat-panel TV products is constantly developing. The popularization of Haier TV energy-saving system solutions, Hisense LED energy-saving backlights, and TCL natural light-adjusting technologies have all promoted flat-panel TVs. Reduced power consumption. Compared with the initial stage of the flat-panel TV consumer market in 2003, the current flat-panel TV products have greatly improved in terms of energy consumption. In the early days, a 32-inch LCD TV consumes about 180 watts to 200 watts. The current low energy consumption can achieve 110 watts. The energy-saving effect of flat-panel TVs is also contributing to social savings. Consumers bring certain benefits.
In view of the energy consumption of flat-panel TVs, experts of the National Radio and TV Product Quality Supervision and Inspection Center believe that the energy-saving effect of a flat-panel TV should be considered at least from three aspects: standby power, power consumption of the whole machine, and energy efficiency index:
1. From the test situation, the standby power of flat-panel TVs on the market is low, and no products exceeding 3W are found (the industry standard requires standby power consumption ≤ 5W, energy-saving product certification technology requires standby power consumption ≤ 3W), mainly concentrated in 0.6-1.5 watts, accounting for 78%, it is worth noting that flat-panel TV products with standby power less than 0.5 watts also account for 12%. The data of the Digital Television Standard Compliance Testing Center of the Ministry of Industry and Information Technology shows that the Haier Baolan K series LK32K1 with the lowest standby power. The LK42K1 LCD TV and Hisense's TLM32P69D LCD TV are only 0.1 watts.
2. The energy efficiency index is the ratio of the center point of the display screen to the power consumption of the whole machine, which can better reflect the energy utilization rate and effect of the product. The higher the general index, the better the energy efficiency. Overall, the LCD TV energy efficiency index is concentrated between 0.8-1.0, accounting for 50%. The highest energy efficiency index of all test models can reach 1.54. It is an LCD TV with LED backlight. It is foreseeable that LED will lead the development trend of flat panel TV energy-saving technology. At present, many brands have begun to focus on promoting LED LCD TV products. The trend of LED as a flat-panel TV upgrade product has been established.
3. Compared with the energy efficiency index, the power consumption of the whole machine can make consumers intuitively feel the energy consumption of flat-panel TVs. Test research found that the power consumption level of flat-panel TVs of different sizes and specifications is uneven, with 46/47-inch LCD TVs being the most prominent. The maximum power consumption of the whole machine under test is 289 watts, with a difference of 118 watts from the lowest, with a margin of 40. %, the space for product energy development is still very large. Shen Jun, director of the Certification and Supervision Department of the National Certification and Accreditation Administration, believes that the key to improving the energy-saving level of flat-panel TVs is to work hard on standards and certification specifications.
Zhao Xinhua, secretary general of the National Audio Video Standardization Technical Committee, said that the standard specifications for energy consumption of flat-panel TVs are somewhat lagging behind air conditioners, refrigerators, and washing machine products. The standard specification for the operating power consumption of flat-panel TVs is a new topic on a global scale. The International Electrotechnical Commission (IEC) has embarked on the development of corresponding standards, which have not yet been finalized. The China Electronics Standardization Institute maintains standards with the International Electrotechnical Commission. The progress of synchronization, I believe that there will be corresponding industry standards will be introduced soon. At this stage, it is mainly to promote and guide the energy-saving certification of flat-panel TVs, so that more consumers can purchase energy-saving flat-panel TVs through simple logo recognition. The first batch of CESI flat-panel TV energy-saving Haier, Hisense, Sharp, Panasonic, Changhong, TCL flat-panel TVs will be attached with the CESI energy-saving certification mark as the first and only representative of developing countries that have entered the International Electrotechnical Commission (IEC). Haier is also the most certified unit of the International Electrotechnical Commission's future High-Tech Advisory Committee (IEC/PACT). Through this move, it is expected to deepen the attention of the entire flat-panel TV industry and the consumer market on color TV energy conservation, and promote the healthy development of the flat-panel TV industry.
