LED displays are usually divided into indoor or outdoor LED displays according to the environment. Outdoor led screens usually have column-mounted, wall-mounted, embedded-mounted and other installation methods. You can also choose a single-sided, double-sided, 3-sided or 4-sided Led sign billboard according to the location of the screen installation, so that people passing by can see the promotional content played on the screen. So how to choose outdoor led screens?
①We choose according to the size of the LED screen. As we have learned, LED displays have many pixels, and our outdoor screens usually have the following models: P2.5P3P4P5P6P6.67P8P10. For example: P2.5 means that the point spacing between the two lamp beads on the screen is 2.5mm. In other words, the best viewing distance for people to watch the led screen is 2.5 meters and further. Standing at a distance of 2.5 meters, we can see the led screen very clearly. We will not see the lamp beads, but the entire led screen is very flat and smooth. So, which spacing pixel should we choose? If the size of the led screen is larger, or the installation location is particularly high, the spacing you choose depends on the distance from which people can view the led screen with the naked eye. For example, if people stand 4 meters away from the led screen horizontally on the ground (they can watch the entire screen completely and comfortably), and the led screen is installed 3 meters high from the ground, then the straight-line distance when people stand 4 meters away from the led screen and watch the led screen is 5 meters. Then, the best led screen spacing we can buy is P2.5P3P4P5. This means that the optimal viewing distance is 5 meters. The smaller the spacing, the larger the pixels, and the more detailed and clear the led screen image will be. Therefore, the smaller the spacing, the higher the cost and price; the larger the spacing, the cheaper the cost and price.
②Choose the material of the led screen according to the environment. Generally speaking, the materials of our LED display screens include: outdoor waterproof iron, iron, magnesium aluminum, aluminum, die-cast aluminum and other materials. What's the difference between them? How do we choose? As we have learned, the outdoor environment is relatively harsh and the requirements for LED displays are relatively high. It needs to be waterproof, moisture-proof, corrosion-proof, wind-proof, high-temperature, low-temperature, etc. Therefore, as everyone's requirements become more and more specific, LED displays of many materials have been produced for everyone to choose from. First of all, in terms of waterproofness, outdoor screens need to be waterproof in all directions. This is the most basic requirement, and these materials can meet it. Second, in terms of screen weight. Their weight order: outdoor waterproof iron cabinets > magnesium aluminum cabinets > aluminum/die-cast aluminum cabinets. Third, from the perspective of moisture resistance, corrosion resistance and high temperature resistance, it is better to choose magnesium aluminum, aluminum and die-cast aluminum. Fourth, when choosing from the heat dissipation and hardness of the material, die-cast aluminum has more advantages. In summary, the quality order of materials is: die-cast aluminum > aluminum > magnesium aluminum > waterproof iron. The better the quality, the higher the process requirements, so the cost will be higher.
As a result, there are a lot of screen test reports, due to the harsh environment in some countries, ultra-high temperature or ultra-low temperature. Our company has a self-developed outdoor screen brightness of 8000-10000 nit, high brush, high and low temperature test report, -40℃ ~80℃, waterproof grade IP67.
So the outdoor waterproof iron cabinet led display P10 has the lowest cost and price, is it bad? Mistake. The model and material of the screen you purchase are simply determined based on the buyer's cost budget and the method and environment of the led screen installation. As long as the led screen installation environment and viewing distance and led screen size are suitable, you can also choose P10 outdoor waterproof iron cabinet. Of course, the smaller the spacing, the better the quality of the led screen purchased with better materials, and the cost will also increase. The purchase and installation experience, and the total cost in the long run, of course, are of higher quality and more superior. After all, people can usually use LED displays for 10 years or even longer.
What about indoor fixed led screens? There are several installation methods for indoor fixed led screens: embedded installation, wall-mounted installation, and stand structure installation.
There are usually models such as P0.9 P1.25 P1.53 P1.86 P2 P2.5. The smaller the spacing, the higher the cost. But here is the current SMD LED display. Small spacing lamps have the problem of easy lamp beads falling off due to installation technology or transportation process. Therefore, for ultra-fine pitch screens, we have developed two LED displays other than SMD, COB and GOB. COB has the highest cost and the best overall effect, and is used for ultra-fine pitch indoor screens. The second is the GOB process. This process is now very mature and the cost has dropped, making it the best choice for everyone. Both COB and GOB processes are filled with glue on the surface of the module. COB is to place glue directly on the surface of the chip, and the technical requirements are higher. GOB is to pour glue on the surface of the lamp bead. All are to protect the Lamp from damage and easy falling off. At the same time, the surface of the screen is as smooth and flat as glass.
Generally speaking, the requirements of led indoor screen are high definition, huge seamless custom size, easy installation and maintenance, and so on. We have several options to choose from here:
① Indoor simple iron cabinet, pre-maintenance, seamless, wired
② Indoor die-cast aluminum cabinet in front of maintenance, seamless and wired
③ Indoor die-cast aluminum cabinet in front of the maintenance, seamless, wireless
Among them, the installation, disassembly, maintenance, safety and aesthetics of scheme ③ are the best, followed by scheme ②, and finally, scheme ①. So, overall, the quality / cost ordering is also ③> ②> ①. Of course, it is not that the scheme ① is not good, because the scheme ① has higher professional requirements for the installation technology, and the adjustment of flatness or some details need to pay more attention to some. Generally speaking, what suits you is the best
In general, the selection of outdoor led display screen or indoor led display screen needs to be considered according to the specific installation place, environmental characteristics, installation method, maintenance mode, labor cost, budget, project quality requirements and other comprehensive factors. Then our experienced salesman will match you according to your requirements and cost-effective product project plan for your reference.
