Technology Of Led Wall - China

price: contact company for price

More buyers are now choosing LED walls, particularly the very popular

LED walls. Their picture quality rivals the best that plasma TVs can

offer, at a more efficient level of energy consumption. A LED display

wall is also superior to the standard LCD TV in terms of overall

picture quality. What gives a LED TV an edge is, of course, the more

sophisticated LED technology. “LED” refers to light emitting diodes,

which provide illumination to the display and produce the picture. LEDs

are better than the cold cathode fluorescent lights found in standard

LCD TVs, in that they deliver better, more vivid images. In addition,

some LEDs have a feature called “local dimming.” This means that when a

picture in a scene requires it, some LEDs are turned off completely. As

a result, some parts of the screen are in total darkness while others

continue to be lit. This produces very dramatic, deep blacks. An LCD TV

is simply incapable of this, because the fluorescent light tubes are

always on, and so the blacks in a picture are never completely black.

There are two ways that the LEDs may be laid out at the back of a

42″ LED. In “full-array” configuration, the LEDs are laid out

behind the entire display. In the “edge-lit” configuration, the LEDs

are placed only on the sides or edges of the panel. But still, even if

only edge-lit, the lighting can reach all parts of the display

including the middle, using what are called “light guides”. Thus, some

42″ TVs may be full-array with or without local dimming, while

others may be edge-lit, again with or without local dimming. The most

common in the market are those that are edge-lit without local dimming,

which are also the thinnest models. The ones that perform best are the

full-array with local dimming type, the original type of LED wall that

came out. Buying a TV has become a lot more complicated than it was

years ago. There are so many things to consider, starting with what

kind of TV to get. Should one go for LCD or plasma? LED or OLED? And

what size is best? Which brand stands out from the rest? The latest TV

technology is the OLED, or Organic Light Emitting Diode. OLED TVs are

the thinnest and offer the best picture quality, but they are the most

expensive as well. Their life span is also not as long as that of other

TVs, hence an OLED TV is not a very practical choice unless you don’t

mind throwing away a hefty sum of money for something that’s excellent

but won’t last very long. Next are the LED display, less pricey but a

cut above standard LCD TVs. LED stands for Light Emitting Diode,

referring to the light used to illuminate the screen and produce a

picture. Standard LCD TVs use fluorescent tubes, which give limited

color saturation with no deep blacks. With 42-inch LED display wall,

you get very clear and crisp pictures, with wide color variety and

superb contrast. Compared to their LCD and plasma counterparts, they

are also more energy efficient. All things considered, 42-inch led

walls are the best choice. They provide excellent picture quality at

reasonable prices. True, they are usually more expensive than LCD TVs,

but the enhanced picture quality is worth the extra dollars. Many

brands offer their own models of 42-inch led display walls. SBC will be

the best choice. SBC Company office website: www.sbcled.com Contract:
