What are the advantages of LED display over other display media (projector, LCD, color strip light)?

Along the way, found that the LED display industry technology development day by day, the standards in all aspects of the higher and higher, the technology is more and more mature, the display effect is also getting better and better.

Today we will talk about a few points LED display compared to other traditional display media, the advantages in the end where.

First, compared with the traditional projector

We know that the traditional imaging principle of the projector is: the first light to the image display element to produce images, and then projected through the lens. Projector image display element including the use of transmitted light to produce images through the type and the use of reflected light to produce images of the reflective type.
Compared with conventional projectors, LED displays have high clarity and brightness. Traditional projectors project light and shadow onto a reflective surface (white wall or white cloth) to produce an image.

In terms of nature, the projector display effect is equivalent to “passive light source”, is reflected once the light source, the brightness is limited, through the test we see the projector's reflective imaging brightness is generally in the 50-100CD / ㎡, basically have to pull the curtains and turn off the lights under the conditions in order to see the playback clearly! Content. Our LED display is divided into indoor LED display and outdoor LED display, indoor light chip is small, the brightness of the conventional 500-1000CD / ㎡, outdoor light chip is large, the brightness of the conventional 4500-8000CD / ㎡. Simply from the luminous brightness than, LED display effect is better than the traditional projector effect is too much.

Second, compared with the traditional color strip light strip
The traditional color strip light is basically used in the building wall outside the lighting project. In recent years, landmark buildings around the application of the outside wall, the classic example is the Shenzhen City Center light show, as well as Dongguan Huiyi City, several buildings outside the strip light decoration, the effect is very dazzling. Although the application of strip light is also very good, but compared with the LED display, or in the display clarity has a clear inferiority.

Another point, strip light decorative display role is basically applied at night, also because of the brightness is not enough, if in broad daylight to see the effect of strip light display, it is not ideal.

Third, compared with the traditional liquid crystal display screen

Traditional liquid crystal (LCD) display, equivalent to the television, its process, research and development, application of a long history, in the field of display below 100 inches can be said to be low-cost, good display effect. In terms of indoor applications, liquid crystal display
It is also true that occupies a considerable application market, ask who still does not have a TV set? Which office does not have a computer? In many shopping malls, offices, conference rooms and other indoor display applications, LCD splicing screen also occupies a large proportion. But its shortcomings are also obvious, that is, the problem of splicing seam can not be solved, and can only be applied indoors. Even the short board is also very obvious, if a place is crashed leakage, then also announced that this piece of liquid crystal display screen of the end of life.

So a comparison, the advantages of LED display immediately came out, seamless splicing, and not afraid of localized damage, localized damage, either change a LED lamp bead can be repaired, or change a piece of the same batch of LED module can be completed the repair of the whole piece of LED display.

One more thing, the brightness of the LED display is obviously much higher than the brightness of the LCD display.
Above all, LED display because of its “active light source” brightness display advantage over other traditional means of display.
