Energy efficiency analysis of CCFL TV and LED TV [Figure]
OFweek Semiconductor Lighting Network: On March 1st, the “Regulations for the Implementation of Energy Efficiency Labeling for Flat Panel TVs†was officially implemented. This means that high-energy products that have not reached the energy efficiency standard for flat-panel TVs will not be allowed to enter the market and will be shipped in the future. Both the imported flat-panel TVs and the imported flat-panel TVs will be labeled with energy efficiency labels. Products that were listed before March 1st can be delayed until March 1st next year.
In order to gain an in-depth understanding of the implementation and effectiveness of the new energy-saving regulations for flat-panel TVs, the author and colleagues conducted visits and surveys on several major stores in Beijing Gome and Suning. Through investigation and analysis, they hope to obtain the current and effective views and data of the flat-panel TV market. For the majority of users to provide reference and help.
The energy consumption of flat-panel TVs has basically reached the standard.
After visiting and inquiring, the energy consumption of flat-panel TVs sold in Beijing's major stores is basically up to standard, and most of the products are energy-efficient at level 1 and level 2. However, most of the products on sale are listed and purchased before, so there is no Paste the energy efficiency logo. Some sales people said that although some products do not have an energy efficiency label attached, the energy efficiency rating can also be calculated by the rated power and size. At present, there will be no high energy consumption products in the market.
It is understood that after three months of inventory cleaning, all brands of high-energy flat-panel TVs are basically sold. People from the China National Institute of Standardization also said that the formulation of standards is subject to prior participation by enterprises. It should be said that enterprises have made preparations in advance, and then there are standards, so the impact on enterprises is not great.
Color TV companies also said that the impact is not big. Tsinghua Tongfang public relations personnel also said that the products currently on the market are basically LED series, the products that are not up to standard have been few, and the relative inventory is less than other color TVs. Yu Haitao, director of the public relations office of Zhuhai Hisense, said that since the standard has been discussed for several years, brand companies have long been prepared for energy-saving technologies. This year's industrial upgrade to LED-backlit TV is also a method to deal with this national standard.
According to the backlight source, LCD TVs can be divided into CCFL and LED. Among them, LCD TVs with LED backlights consume less power. A professional technician has done such a calculation. A typical flat-panel TV with a power consumption of 200 watts consumes 0.2 kWh per hour. A TV product that uses LED backlight technology, the whole machine consumes The power consumption is 50% less than that of a regular TV, and each TV can save 0.1 degrees per hour.
After the store inquiry, the LCD TV products currently on sale, CCFL backlight TV energy efficiency standards are mostly 2 and 3 energy efficiency grades, while LED backlight TVs are basically 1 and 2 energy efficiency, LED backlight LCD TV Compared with the traditional CCFL LCD TV, it has a huge advantage in energy consumption.
Through the random sampling of CCFL and LED LCD TVs in the store for 20 investigations and calculations, the results show that CCFL LCD TV secondary energy efficiency products are 55%, first-class energy efficiency products are 45%; LED LCD TV first-class energy efficiency products are 70%, The secondary energy efficiency product is 30%.
According to a report released by the Consumer Electronics Research Office of the China Electronics Chamber of Commerce, in 2010, LED TV sales in the urban market have reached more than 30% of total sales. The industry generally believes that by 2011 New Year's Day, LED will fully exceed LCD, and the annual retail volume is expected. With more than 24 million units, the retail volume of LCD TVs will be around 20 million units.
Globally, according to the WitsView survey, the penetration rate of LED TVs in 2010 was about 18%, equivalent to 34 million units. Under the cost improvement, the price of LED backlights or LED TV panels in 2011 is expected to be higher than 2010. The sharp decline in the year will greatly stimulate the demand of users. It is estimated that the penetration rate of LED TV in 2011 will be 43%, and the number will reach 94 million units.
