Older CCFL backlights for LCD panels used quite a bit more power, and older plasma TVs used quite a bit more power than recent models. [ 58 ] [ 59 ] Plasma displays do not work as well at high altitudes above 6,500 feet (2,000 meters) [ 60 ] due to pressure differential between the gases inside the screen and the air pressure at altitude.
For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [35] while OLED can use more than three times as much power to display a mostly white image compared to an LCD.

Another competitor, plasma display technology, consists of small cells of ionized gases that emit light–a process that requires a relatively large amount of power. And a conventional laser television, such as the LaserVue, made by Mitsubishi, uses red, blue, and green lasers and a micromirror device that combines and directs the light.
