Any product has advantages and disadvantages, LED display is no exception, then what advantages and disadvantages of LED display, how do we make use of the advantages and disadvantages, in which occasions to use LED display, which occasions to use other display products, these we have to figure out in advance. In fact, in the current industry mainstream several large screen display products, LED display belongs to a very wide range of applications, whether it is market share or market share is higher than LCD and DLP, especially in recent years, with the development of closed technology and dot spacing technology, LED display resolution greatly improved, stability is also getting higher and higher. Its main application has become from outdoor screen to indoor, indoor can use large screen products, such as some meeting rooms, command centers, data analysis centers and other occasions LED display is often used.
There are many specifications of LED display, mainly divided into outdoor and indoor two categories, outdoor screen is mainly from P20 to P4 or so, indoor screen is mainly from P3 to P0.9 or so, this is because outdoor occasions are usually far away, so use some large spacing products, and indoor occasions are close to the viewing distance. Therefore, in order to ensure clarity, some small-pitch leds are used. In addition, the closed technology of LED display screen also has two kinds of SMD table paste and COB flip, of which COB package is mainly used in the micro-spacing of P1 or so.
1, waterproof, sun protection, installation environment is not limited LED display is composed of a piece of unit board splicing, in the unit board distribution of many LED light beads, followed by the power board, which after a simple waterproof treatment can reach the waterproof level requirements, and can achieve the normal display in the case of exposure, So we see that most of the outdoor screens are now used LED displays, such as some square screens, sports venues, roadside advertising displays, etc., which is also an advantage of LED displays that are relatively large, and other display products can not be done. 2, high brightness LED display brightness is very high, and can adjust the high and low parameters, if used outdoors, you can turn its brightness up, if it is used indoors can turn down the brightness, so that it can correspond to the outside light, that is, to ensure that the screen can be displayed normally, but also to achieve no reflection phenomenon, The high brightness of the LED display is also the main factor that it can be used in the outdoor environment, because the outdoor is usually faced with direct sunlight, which requires that the brightness of the display must be high enough. 3, no splicing trace LED display in splicing is no trace of splicing, it does not have the effect of splicing like LCD, so the whole screen is the same, especially suitable for full-screen display, which is related to its technical principle, which makes it can be applied in some advertising, play video or data text and other content occasions.
1, there is a certain dead lamp phenomenon, there is after-sales service because the LED display lamp beads are welded on the PCB board, due to welding technology, it has a certain dead lamp rate, in the production, transportation, installation and later use are easy to cause the drop of the lamp beads, once the lamp beads fall then the lamp will not show, Commonly known as the dead light, the pixel will no longer display the content after the dead light, and it will have a very obvious impact on close viewing, at this time, if you want to repair it, you can only be a technician door welding or replacing a unit board. Although the packaging technology is more and more advanced, and can also be coated, etc., but there are still some after-sales, even if the undead lamp, there will be a flower screen, do not display signals, etc., so there is still a after-sales situation, which requires later after-sales protection and a certain cost. 2, the resolution is general, the close-up effect is not clear LED display resolution is determined by the distance between the point spacing, due to the limitation of packaging technology, the current LED display point spacing can not be as small as LCD, which leads to its resolution is high and low, in general clarity, especially when watching at close range. The picture is not particularly clear. In general, the advantages of the LED display are very obvious, including the installation environment is not limited, high brightness and no joint, etc., the same shortcomings are also prominent, the after-sales rate is slightly higher, and the clarity is general, so it should not be used for a long time continuous boot use, and the more remote viewing is more suitable.
