The so-called LED TV refers to the "LED backlight LCD TV". Compared with the previous LCD TV, it uses the LED backlight instead of the CCFL backlight. LED TVs are characterized by high brightness, ultra-thin, environmental protection, long service life and more beautiful appearance.
LED TVs first have a wider color gamut, especially for RGB-LED backlights. Through LED devices that can emit high-purity red, green, and blue light, the wide color gamut range that traditional CCFL LCD TV sources cannot achieve is achieved. The quality of LED TVs is more prominent than traditional LCD TVs. Secondly, its material is environmentally friendly. Now more and more consumers are concerned about whether the use of goods is environmentally friendly and whether the body is harmful.
In addition, the power consumption of LED TVs is lower than that of traditional CCFL LCD TVs. The average operating power of 42-inch LED TVs is only about 60 watts, which is more than half of that of ordinary LCD TVs. Again, its long life span, LED backlight life is generally about twice that of CCFL. Finally, its stylish and ultra-thin, LED TV can make the body thinner and more fashionable.
In the early days of LED TV development, high cost was a major factor affecting the popularity of LED. At the beginning of LED, the cost of LED backlight panel for 42-inch LCD TV was more than three times that of CCFL, and now with the most LED industry in mainland China. The upstream layout began, and the supporting facilities were gradually improved. Compared with the cost of CCFL backlights, the LED backlight panel has almost the same cost, and the output is improved and the cost is reduced. This will undoubtedly directly affect the terminal market.
On December 1, 2010, the "flat-panel TV energy efficiency limit value and energy efficiency rating" began to be implemented. According to the requirements of the flat-panel TV energy efficiency standard, the flat-panel TV energy efficiency rating is divided into three levels: one is the target value of energy-saving products, and is set in principle. In the current market, the highest level of similar products; the second level is the evaluation level of energy-saving products, the index setting should be higher than the average level of the product market; the third level is the market access level, and the indicator setting is mainly used to eliminate high-energy-consuming products in the market. Products that are not in the grade will be forcibly eliminated.
The implementation of flat-panel TV energy efficiency standards, how many non-standard TVs in the market will be eliminated, will have a great impact on the whole machine companies has become the focus of the industry. According to the data released by the National Radio and Television Product Quality Supervision and Inspection Center, 14.5% of the LCD products are unqualified, and most of them are CCFL backlight LCD TVs.
Green energy conservation has changed from a concept to an actual action for the color TV industry. All enterprises are striving to improve the energy efficiency of each production process and the energy conservation of products. The industry generally believes that the implementation of energy-saving standards for flat-panel TVs will further promote With the development of LED LCD TVs, the penetration rate of LED backlight TV retail sales has increased from 3.7% at the beginning of 2010 to 31.5% in October, and its energy-saving ultra-thin characteristics are one of the important reasons.
As of March 1 this year, all flat-panel TVs will use China's flat-panel TV energy efficiency logo. During this period of time, the remaining CCFL LCD TVs on the market will be promoted at a lower price, along with consumers' household appliances. The choice is more green, energy-saving, LED LCD TV will completely eliminate CCFL backlight LCD TV this year.
