Technology type

There are three main HDTV technology types available in the market today - LCD, LED and Plasma.

In general, Plasma TVs are the most power-hungry followed by LED and LCDs. A typical Plasma TV can consume about 300W of energy, compared to about 175W for an LCD screen.

The reason for the need of extra juice is how the way a plasma TV is built - each pixel is an individual light source. When the TV is set to display a higher resolution in this case (say from 720p to 1080p), power consumption increases too since each pixel is directly 'responsible' for it's own quality settings.

LCD TVs on the other hand, display an image in the LCD panel that is illuminated by a backlight.This means that power consumption is relatively unrelated to picture resolution.
