Display in Rotterdam showing how to use Google Assistant with a smart plug to turn on an electric fan (Dutch: zet de ventilator aan)A smart plug is a power plug and socket (also known as a wall plug, outlet, or electrical connector) which can be fitted between power cords and sockets to function as a remote-controlled power switch.
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.

Plasma displays modulate the "on" time of each sub-pixel, similar to DLP. Movie theaters use a mechanical shutter to illuminate the same frame 2 or 3 times, increasing the flicker frequency to make it less perceptible to the human eye.
Miracast is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View (by Samsung), [3] [4] SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows 11) and Connect (in Windows 10), wireless display and screen casting.
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.
"Switched socket-outlets and connectors with or without interlock" applies to self-contained products that combine within a single enclosure, a socket-outlet or connector according to IEC 60309-1 or IEC 60309-2 and a switching device, with a rated operating voltage not exceeding 1000 VDC or VAC and 500 Hz, and a rated current not exceeding 800 A.
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.
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens , but some newer types of projectors can project the image directly, by using lasers .
