At present, the commonly used splicing large screen display products on the market has LED screen, LCD screen LCD splicing, projection, and DLP screen devices, such as LCD splicing screen compared with the traditional, DLP projection screens and other equipment, not only display effect is better, and the price is very high, for most of the market share is growing in the field of security monitoring display.And with the development of LED display technology, now point spacing can be done under the p1.0, with LCD splicing screen 0.88 mm difference is not big, so the display resolution also has a lot of improvement, but from the point of view of practical application, although the LED screen market share is higher, but the LCD splicing screen has a unique advantage.
A display, hd resolution
We all know that belongs to a kind of high resolution Lcd splicing screen products, each screen resolution can be reached 1920 * 1080, four pieces after joining together can also play 4 k content, can meet the requirements of the current mainstream sources play.And although LED products with small spacing, its resolution also had the very big promotion, but if from a closer look, in the display some text content or there will be some Mosaic phenomenon, it still cannot compared with LCD splicing screen, for small spacing and a square to tens of thousands of yuan of above, at least compared with LCD splicing screen for the entire input costs will be bigger.
Second, the technical stability, basic no after-sales
Lcd splicing screen USES is back light-emitting display technology principle, the entire Lcd panel part if not affected by outside force collision or extrusion, basically there will not be damaged, so service life can reach more than 60000 hours, and small spacing LED products we all know that is made up of rows of lights, with different chip brand, encapsulation factory technology is different, the entire screen will have certain death rate of light, the display will have a small black dot or small red dot, then to manufacturer for repair or replacement, and the frequency is very high, so from this point of the LED screen after-sales rate is higher.
Three, the display function
Lcd splicing screen or small spacing LED display its basic principle is a large display, the display function mainly through the backend control device, and the Lcd splicing screen has the advantage of each screen, is a unit which can realize the unit within the division, according to also can achieve roaming across the screen display, overlay effect, it is particularly suited to some command center occasion;And small spacing in the LED screen display function is less powerful, while also can achieve a certain amount of segmentation, etc, according to the division number or roaming function is not strong as LCD splicing screen.
LCD splicing screen compared with the small distance between the LED screen while advantage obviously, but from the point of installation environment, LCD splicing screen is only applicable to indoor, because it does not have waterproof function, the LED display is different, it can have waterproof function, can be widely used in outdoor large screen, the joining together of as propaganda poster display.
