LED challenge LCD

When the plasma (PDP), liquid crystal (LCD) has become the most popular TV products for home users, LED TV has become the most popular buzzword in the TV market. Since the CES exhibition emerged since the second half of 2008, the flat-panel TV manufacturers began to LED (LightEmittingDiode, light emitting diode) TV as a high-end products to promote, domestic and international mainstream brands have launched new products using LED technology. In the 2009 International Consumer Electronics Show (CES), LED TV has become a hot topic of attention, the major TV giants have exhibited their own LED tv. In the top 9 The Associated Press CES 2009 on the top of the product, LED TV impressively among them. Compared to the traditional LCD LCD TV, LED TV in the screen performance, environmental protection and energy saving, ultra-thin appearance, entertainment and other aspects have been fully upgraded. Excellent screen life longer LED light source is composed of a large number of grid shaped semiconductor, each lattice has a LED semiconductor, so that the LED backlight on the successful realization of the light source of the plane. To solve the uneven brightness of the screen light leakage and etc.. The flat light source not only has excellent brightness uniformity, but also does not need a complex optical path design, so that the thickness and weight of the TV are greatly reduced, but also has a higher reliability and stability. In the light of life, LED TV service life up to 100 thousand hours. According to 5 hours a day to start the calculation, a LED TV can be used for nearly 55 years. Energy saving and environmental protection does not contain mercury with the consumer's demand for ultra-thin, high quality and other requirements continue to improve, flat-panel TV energy consumption, environmental issues have become the focus of attention. Flat panel TVs consume more power than ordinary CRT. 2008 sales of 12 million flat-panel TVs, such as the work of each TV every day for 4 hours, will consume more than 2 billion 400 million kwh per year. LED brightness can be adjusted with the brightness of the screen, compared to LCD TV effective energy saving can reach more than 30%. In terms of environmental protection, although the manufacturers have been trying to reduce the mercury content in the LCD TV fluorescent tube, but no mercury can not do. The LED backlight, the advantage is that no lead and mercury and other toxic and harmful substances, is a true green light source. With the advent of the era of LED TV, LCD TV market competition has reached a white hot stage. At present, both domestic manufacturers or joint venture brands, all vigorously develop LED products. At the CES show, LED products appear on such a large scale, which has proved the development strategy of the enterprise. LED technology has become a screen full HD, body thin, speed drive technology, experts predict a development trend of TV industry, the TV market in the coming LED era.
