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.
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.

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. It may ...
A variation is a video projector, using similar technology, which projects onto a screen. Three types of projection systems are used in projection TVs. CRT rear-projection TVs were the earliest, and while they were the first to exceed 40", they were also bulky and the picture was unclear at close range.
A laser projector is a device that projects changing laser beams on a screen to create a moving image for entertainment or professional use. [1] It consists of a housing that contains lasers, mirrors , galvanometer scanners, and other optical components.
Schuko sockets can accept two-pin unearthed Europlug (CEE 7/16) and CEE 7/17. Less safely, Schuko plugs can be inserted into many two-pin unearthed CEE 7/1 sockets and into some sockets with a different form of earth connection that will not mate with the earth contacts on the Schuko plug (e.g., some variants of the Danish socket).
The recessed type 23 socket will accept plugs of types 11, 12, 21, 23 and the Europlug. Again, the three-phase power socket is compatible with single-phase plugs, either of 10 A or 16 A ratings: [58] The type 25 plug has three rectangular pins of the same dimensions as type 23, plus two rectangular pins of the same dimensions as type 15. The ...
