Alternate lighting of surfaces (ALiS) is type of plasma display technology jointly developed by Fujitsu and Hitachi in 1999. [1] [2] Alternate lighting of surfaces uses an interlaced scanning method rather than a progressive one. This technique allows native lower resolution plasma display panels to display at higher
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.
NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
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.

BS 546, Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50–60 Hz) circuits up to 250 V is an older British Standard for three-pin AC power plugs and sockets. Originally published in April 1934, it was updated by a 1950 edition which is still current, [1] with eight amendments up to 1999. BS 546 is also the ...
AC power plugs and sockets connect devices to mains electricity to supply them with electrical power. A plug is the connector attached to an electrically-operated device, often via a cable. A socket (also known as a receptacle or outlet ) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit.
Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are different kinds of flat panel displays. This list includes LCD, OLED and microLED display manufacturers.
The intensity is varied by modulating the "on" time of each pixel within the time-span of one color. Multi-chip DLPs are not represented in this sketch, but would have a curve identical to the plasma display. LCDs have a constant (backlit) image, where the intensity is varied by blocking the light shining through the panel.
