Television has been with us for many decades now and up until recently almost all TV's found in peoples homes were of the conventional CRT (cathode ray tube) type. LED TV is just one of many exciting recent developments in the world of modern television design. The LG 42LE5900 is an interesting new product development within this category.
The other name for this product type is LED-back lit LCD Television but this is a clumsy term so many manufacturers simply use LED TV for marketing purposes.

LED TV is different from true LED displays that are used mostly in outdoor billboard type advertising, some types of store signage and as destination displays on public transport vehicles. They are also used a lot in airports as the boards on which flight arrivals and departures are displayed.
Essentially LED TV refers to a system where the fluorescent back lighting used in traditional LCD televisions is replaced by back lighting provided by light emitting diodes (a type of semi conductor light source).
There are two common types of design used in LED televisions: those using dynamic RGB (Red, Green, Blue) LED's located behind the LCD panel and the other type using white edge LED's and then a special diffuser to spread the light evenly across the panel and produce a uniform colour range across the whole screen.. There are several advantages to LED lit LCD's over those lit by fluorescent lights.
One big advantage LED back lighting has over florescent is significantly lower power consumption, that not only saves you a lot of money in electricity bills but is also very good for the environment as far less energy is being used. In today's economic climate we all want to save money as well as doing out bit for the planet.
Another advantage to LCD TV is that it allows for much thinner designs to be used when producing the casings, making the product very flat and compact. In our modern world and lifestyle where space in the home is often limited this is a very useful feature. Aesthetics (the look of the product) is also very important to many customers who want their television 's looks to fit in with the overall design and decor of their modern home. Just think, who wants a bulky old fashioned looking TV standing on a table when you can have an ultra modern super thin LED TV mounted unobtrusively on the wall?
Aside from the power saving and cosmetic aspects of LED TV's these products are also typically 100 hertz display compared to the usual 50 hertz of conventional televisions. Basically the hertz measurement (also abbreviated to Hz) indicates the amount of time per second the image changes. So an LG 42LE5900 LED TV displays one hundred images per second compared to the fifty images per second of a conventional TV.
If you are looking for a new TV and want one that has useful features, up to date technology and that also looks good with a slim design then you should consider buying a product that uses advanced electronics like the LG 42LE5900.
