LCD- Liquid-crystal display TV’s are thin and light compared to their predecessor Cathode-Ray tube or CRT TV’s. These sets were bulky and not environmentally friendly as an example. Reduced manufacturing costs meant LCD’s by-passed the CRT set. There were teething-problems with the LCD set when first introduced , and complaints of poor images were soon overcome and now increased technology suggests they are even taking-over the latter Plasma set as the number-one preferred seller.
Colours blend together to produce pixels in these sets but despite their improved visual impact , this comes at a cost to energy-efficiency arguably.
Sets come in sizes from the regular 20-30” range to the much larger screen 40+” sets that were once the domain of the new Plasma TV’s.
Prices are again very wide-ranging and you can pay anything from the usual couple of hundred pounds to several thousand by practically all the recognised manufacturers , with all the major online retailers.
LED – We have to mention LED TV , although it is a variation of the LCD set. The technology here relies on backlighting rather than the CCFL or cold-cathode fluorescent lighting of the LCD. Although it is not a true LED display this TV is thinner , has better power consumption with a brighter display. However , at the price of improved energy consumption , these sets are more expensive.
This improved , slimmer profile has allowed this technology to be used in laptop design and manufacturers such as Dell claim that it has produced one of the highest colour displays available.
Some of you may naturally be confused with the difference between LCD and LED , which is understandable. You won’t be confused when shopping with the price because the LED TV is near £4000 with some retailers for the bigger sets.
