When compared to a plasma, no. Plasma tv's use much more energy. However, LED technology is the most cost efficient.
LCD are usually better and plasma screens use more energy and are bigger.
An LCD will have a generally lower energy requirement than a Plasma monitor. But Plasma monitors energy requirements change with the brightness. If something on the screen is dark, it will use less energy.
LCD monitors use far less energy then plasma monitors.
fossil fuels are the least costly for us to use.
LCD TV's are comprised of individual lights and plasms TV's use high levels of concentrated energy. The energy can be more easily converted into dark colors than the LCD can.
Toshiba DLP lamps are energy costly to have and use, because they have to be replaced fairly often. More information can be found here: http://www.ehow.com/how_7206948_change-lamp-toshiba-dlp-tv.html
Yes!LED TV is more Expensive than LCD.
Yes, LCDs use a lot less energy
LED displays typically require less power compared to LCD displays because LEDs are more energy-efficient in producing light. LED displays are also known for their higher brightness levels and lower heat emission, contributing to their energy efficiency.
Power consumption varies between individual models, but LED-backlit LCD televisions typically consume less power than plasma televisions.
if you are using CRT moitor than computer will use more energy if you are using lcd monitor than TV will use more energy . i am not saying for laptops .they (laptop) also use very less energy compared to desktop .but totally depend upon type of monitor.
Two examples of flat panel monitors are Light-emitting diode display (LED) and Liquid-crystal display (LCD). LCD monitors light the entire backside of the LCD panel using a cold compact florescent light while LED monitors use its own light to provide the backlight. LED lights more energy efficient than the cold compact florescent light used by LCD.
