LED "illuminate" LCD TV in the future

Bring flat-panel TVs now, people all know that LCD and plasma, after long-term media bombing, I believe that many consumers are aware of these two different display technology strengths and shortcomings, such as response time and energy consumption of the plasma, these are for people to buy flat-panel TVs have to consider and accept the shortcomings. With the passage of time and development panel technology, recently a new LED LCD panel began to enter the people's attention gradually, as one of the best solutions for liquid crystal response time at present, LED liquid crystal has been used in some high-end notebook, according to the industry is expected, the latest from the end of this year, LED will be through the LCD TV really into people's living room.

In fact, LED has long been around us to mention LED, many people do not know much about it. LED lamp, also known as light-emitting diodes, compared to other light sources, the power consumption of a single LED lamp is minimal, longer service life. At the same time with the brightness stability, rich colors, our daily life, the traffic lights, large outdoor billboards, etc. are a form of LED. Although the application has been so extensive, but LED came back to the LCD screen in recent years or something. As we all know, when we use LCD TV to watch the motion picture, especially the high-speed motion picture, more or less there will be some trailing phenomenon exists. This is because the LCD display principle which, since the LCD itself is not luminous, rely on light source to provide light, change speed and reaction speed of the cold cathode fluorescent lamp behind the traditional LCD screen can not keep up with the picture, this is the main reason of liquid crystal tail. In addition to the response speed, compared with the traditional LCD, LED backlight can also bring higher image quality, longer life, higher color saturation and other advantages. In addition, the LED life is very long, the service life of up to 100 thousand hours, if you press a day to start the calculation of 5 hours, a backlight using LED backlight LCD TV can be used for nearly 55 years without brightness. Two problems hinder the popularization is known as "the father of liquid crystal Sharp Co technical staff told reporters, SHARP started early on LED research, research progress so far, traditional CCFL can" regional brightness control "on the screen, the LED backlight, on display image analysis, in order to achieve the screen brightness control part, the bright light of the picture, the dark dark, so as to reduce power consumption and improve the color reproduction ability. This means that the use of LED backlight technology will become a hot spot. Since the advantages of LED so much, why not in the LCD TV mass application? In fact, the reason boils down to two aspects, cost and design. SONY side said, LED backlight LCD TV technology research is indeed in progress, but the cost has not been reduced to allow consumers to accept the extent of ordinary. SONY also has related products launched in Europe and the United States, but a ten inch TV price is now about 40 inches or so ordinary LCD TV is not much difference. Samsung has launched its 70 inch LED backlit LCD TV, from the evaluation of professional media, is solves the LCD TV tailing and contrast and color saturation, but lie in front of the consumer is still a price threshold, but need to pay dozens of case, tens of thousands of deposit. In addition to the price, in the design, the use of LED backlight will bring greater changes. The designer AUO said that apart from the cost, the LED backlight has a lot of room for improvement, such as how to convert electrical energy into light energy more efficiency, thereby reducing heat generation, improve the utilization rate of energy. How to start from the chip design, the LED dynamic control, make full use of the advantages of fast response, only in the needs of their work when lit, in order to reduce the energy consumption under the premise of not affecting the viewing effect, the current situation is not particularly mature. Due to the above problems, at present, LED backlight is only part of the high-end notebook computer applications. The best "upgrade" LCD line although there are two design costs and hinder its large-scale application problems to be solved, but the cost and effect, LED has been regarded as one of the best ways for many manufacturers to "upgrade" lcd. SHARP said that from the current point of view, LED backlight LCD TV cost is indeed high, but with the future mass production, the cost will be reduced with the increase in production. In addition, along with the global environmental awareness, reduce the power consumption of LCD TV has become a large number of manufacturers are beginning to pay attention to the subject, from this perspective, the use of LED backlight can be regarded as a solution of a low cost. In addition to Samsung, SONY, SHARP and other vendors, PC vendors such as BenQ and AU Optronics panel manufacturers have begun to play an important role in the popularization of LED in. AUO CEO Chen Xuanbin said, according to their plan, originally expected by the end of 2011 will be fully use LED notebook computer terminal backlight module, because more and more customers pay more attention to environmental protection and energy saving, LED backlight application is accelerating, it seems, is expected to reach the target in the end of 2010. At the same time, now most of the LED backlight used in high-end notebook computer, the price and the traditional cold cathode fluorescent lamp is not a small gap, but as the technology matures, the cost will be more and more low, expected next year, the LED backlight notebook computer will be able to account for nearly half of the market. this
