LED TV Facts And Buying Guide
Although these screens are called 'LED TVs', really they are LCD TVs but they use LED back lighting technology.Samsung, for example, have been asked to resubmit their marketing terms to explain that the LED TVs they are advertising are not purely LED but are LCD TVs with LED technology. This technically means that LED LCD TVs are LCD TVs with LED lighting technology, which can either be backlit or edgelit. Backlit LED LCD TVs have a panel of LEDs behind the LCD screen which creates more or less light to enhance the image displayed. Edgelit TVs have LED lights surrounding the edge which points light to the necessary areas and also allows for the body to be slimline.
Samsung are by far the biggest LED TV manufacture, they have a reported 63% of the market share in the UK.Samsung expected 2009 to see sales of around 2 million LED LCD TVs, but beat this figure with sales of 2.6m, and for this year they expect sales to jump to a staggering 10 million. Sharp in second place for market share with 27.9%. However, other leading brands have realised the potential sales for the coming years and are continuing to launch competitive technology and prices. By 2013, it is expected that over 156 million LED LCD TV units will have been sold.
LED LCD TVs can be up to a third slimmer than LCD TVs, due to the size of the LEDs compared to the CCFL (Cold Cathode Fluorescent Lamps) used in LCD TVs. LED LCD TVs also create more vivid images with improved contrast and colour spectrum. Viewing angles are improved upon too, and now rival those of a Plasma TVs. Although these factors are very important for the overall performance of the LED LCD TV, one of the main selling points is the reduction in energy consumption. Edge lit LED LCD TVs use 40% less power than an LCD TV as the mercury-free LEDs that are used require less energy to be lit. Most manufacturers are also including power saving and environmentally friendly features too, so your carbon footprint and energy bills can be reduced. The effect on power consumption can be quite dramatic in comparison to Plasma and other LCD TVs. Ambient light sensors used on LG TVs, for example, also reduce power by sensing the light in the room and adjusting the TVs brightness accordingly.
There have been many new LED TV ranges launched recently with Samsung introducing super slimline models at under 1 inch thick, LGs with 240Hz TruMotion LED backlit TVs, Sonys individually controlled LED backlit panel, Toshibas new LED backlighting technology with 240Hz panel and Sharps Ultra Bright LED system.Expect LED TVs to be big in 2010.
