3D Televisions 
 
 
3D images are displayed by offsetting pictures filtered separately to the left and right eye. This is done in two ways: By wearing eyeglasses to filter the separate pictures to each eye; or a light source splits the picture directionally into the person’s eyes (no glasses required).

Energy Usage
Popular Mechanics tested power consumption on the following models with a watt meter:

 

  • 52-inch Sony Bravia LX900 LED-lit LCD - fluctuated between 88 and 116 watts while showing 2D, and between 120 and 139 watts in 3D.
  • 50-inch Panasonic TC-P50VT25 plasma - bumped from a 2D range between 109 and 155 watts to a 3D range of 135 and 156 watts.
  • 46-inch Samsung UN46C8000 LED-lit LCD - the largest 3D power premium belonged to the Panasonic, which jumped from a power usage of between 150 and 172 watts, all the way up to a 3D reading of between 290 and 332 watts.
 
When purchasing a 3D television, always be sure to look for the ENERGY STAR® label.
