发光二极管是什么?它是LED的中文名称,LED全称叫作(LightEmiting)。与传统的发光灯泡相比,使用LED灯管会有更多的优势,例如能够节省更多的电力、能把器材的体积缩小、环境污染低、适合大规模生产、反应速度快、寿命长且不容易受到破坏。既然有这么多的优点,LED技术的应用一定有着很广阔的发展空间。记得我们在之前的LED投影机策划中已经做过相关的介绍,而在本期的特别策划中,我们将会围绕目前主流的LED液晶平板电视作详细介绍。LED技术其实已经诞生了很长一段时间,不过在早年的应用中,一直没有得到影音大厂的重视和开发,原因是早期的LED灯管的亮度都不高,整合到显示设备中使用的可能不大。而就在近几年内,LED技术的发展突飞猛进,LED的发光效率不断提升,让LED的适用环境越来越多,许多影音大厂在生产显示设备时,都加入了LED发光技术,例如之前介绍过的LED投影机,而采用LED用作液晶电视的背光源也是很适合的。有留意早期液晶电视发展的朋友都知道,目前大部分的液晶面板都是使用CCFL(冷阴极荧光灯)作背光源的,而LED相比CCFL则有着许多领先的地方,虽然如此,在LED液晶电视的制作工艺与技术运用上却比使用CCFL灯管的液晶电视都要复杂,所以目前的LED液晶电视还是比使用CCFL灯管的要昂贵一些。不过可以预期的是,LED液晶电视会是未来发展的方向,LED背照灯已经开始全面配备于液晶电视中。各液晶面板公司2010年计划的LED背照灯面板合计供货量达到5500万张,约占液晶电视面板的1/4。在OLED电视还没有来到之前,LED液晶电视会在市场上占据一个很长的时间,而这个时刻已经到来了。目前主流的液晶生产商都推出了旗下的LED液晶电视产品,在节能环保的世界潮流的驱动下,挑选LED液晶电视会是目前主流的消费方向。
What is a light-emitting diode? It is the Chinese name of the LED, LED full name is called (LightEmiting). Compared with the traditional light-emitting bulbs, the use of LED lamps will have more advantages, for example, can save more electricity, can reduce the volume of equipment, low environmental pollution, suitable for mass production, fast response and long life Not easily damaged. Since there are so many advantages, the application of LED technology must have a very broad space for development. I remember we have done in the previous LED projector planning related presentations, and in this issue of special planning, we will focus on the current mainstream LED LCD flat-panel TV for more details. LED technology has actually been born for a long time, but in the early years of application, has not been the attention and development of audio and video manufacturers, because the early LED lamps are not high brightness, integrated into the display device may be used Not big. In recent years, LED technology by leaps and bounds, LED luminous efficiency continues to increase, so that more and more suitable environment for LED, many audio and video manufacturers in the production of display equipment, have joined the LED lighting technology, such as the previous introduction LED projectors, but the use of LED backlight LCD TV is also very suitable. Have noted that the development of early LCD TV friends all know that most of the current LCD panel is the use of CCFL (cold cathode fluorescent lamps) for backlighting, and LED compared to CCFL has many leading places, though, in the LED LCD TV Production technology and technology than the use of CCFL lamp LCD TV are complicated, so the current LED LCD TV is still more expensive than the use of CCFL lamp. However, it is expected that, LED LCD TV will be the future direction of development, LED backlight has begun fully equipped with LCD TVs. The LCD panel company plans in 2010 the total LED backlight panel supply reached 55 million, accounting for about LCD TV panel 1/4. Before the OLED TV has not come before, LED LCD TV will occupy a very long time in the market, and this moment has arrived. The current mainstream LCD manufacturers have introduced its LED LCD TV products, energy-saving environmental protection in the world trend driven by the selection of LED LCD TV is the current mainstream consumer.
