The light is dispersed across the screen. Full-Array lighting involves a number of rows of diodes behind the entire surface of the screen allowing for more control over dimming and brightness as the diodes can be switched on and off.
If you are not familiar with the current TV technologies, it can be difficult understanding the choice between LCD and LED televisions. Although LED TVs and LCD TVs both use Liquid Crystal Display technology, the key difference is that the LED TV uses Light Emitting Diodes while the standard LCD TV uses fluorescent lamps. When it comes to LCD TVs, Edge-lit television sets are normally lighter and thinner than a Full Array because the lighting source takes up less space. Full-array television sets are thicker and heavier, but one section of the LED panel can be dimmed while other sections stay bright which improves blacks and contrast in the television image. Edge lighting television sets are the lightest and thinnest TVs on the market.
LED TVs are more expensive than LCD televisions. Each type of television has its own advantages and disadvantages. The choice will depend on your needs and television preference.
A NATION OF CONVERTS?
Millions of us have switched over to using CFLs (compact fluorescent bulbs) in our lamps, overhead fixtures, sconces and exterior lights. And, for the most part, we have noticed a slight lower rate in our electric bills because the CFL 60 watt bulb we put in our desk lamp only draws 14 watts of electricity. The reduction in electrical power usage is not dramatic for the typical American household because the real culprits which demand much more electrical power are our old and outdated refrigerator, water heater and dryer. These appliances, as well as well as heat pumps and air conditioners, are responsible for our very high utility bills.
The savings we dont see is that, because millions of us have switched from regular incandescent bulbs to CFLs, we have made a significant reduction of our impact on the grid and have, as a nation, lessened the demands on our electrical utilities.
Introduced to the market in 1980, CFLs have improved considerably--costing less, lighting instantly, not flickering and giving off a good, white light. But to date only abut 5% of light bulbs purchase are CFLs, the rest being incandescents. CFLs remain a small, niche market product and as a "green" resource, their credibility is still relatively low.
CFLs have freed us from our former high demands on electrical power, but much still can be done to alleviate our high energy usage. Converting to alternative energy resources like solar and wind power will significantly lower our electrical usage. The more energy-efficient our appliances become and the more we replace our old appliances and HVAC systems with energy star rated products, the less dependent we are on the grid.
Everyone agrees this would be for the better, less usage, less dependence, less demand on utilities and lower energy cost for the consumer.
THE ADVANTAGES OF CFL
The typical American household has between fifty electrical sockets and an average of twenty to forty illumination sources including lamps, sconces, ceiling fixtures, exterior and security lights and night lights or auxiliary lights. TV Lamps For Less, TV Lamps For Less, Television Lamps For Less
