It is the first time for a newbie to come into contact with an LED electronic screen. Are you always confused by various parameters? Looking at the "high brightness" and "long life" promoted by the merchants, my heart pounded - do these indicators have any water? Today we are going to talk about it.​ ​Three important factors for choosing LED electronic screens​ ​Where is it hidden?

Let me be honest first, choosing an electronic screen is like choosing a house. ​ ​Is the foundation stable?​ ​Most important. This foundation is the manufacturer's R&D and production capabilities. Manufacturers with their own factories control the entire process from chip packaging to finished product assembly, which is like eating home-grown vegetables with confidence. For those "OEM" manufacturers that don't even have production lines, if they find factory A today and switch to factory B tomorrow, the quality fluctuations are like riding a roller coaster. How to judge, you ask? Check the official website to see if there are actual production workshop videos, or directly ask for a copy of the factory's ISO certification. This is much better than sales bragging.

Let’s talk about it again​ ​Technical hard indicators​ ​. The higher the brightness, the better. For indoor use, 800-1200cd/m² is enough, and for outdoor advertising screens, 4000cd/m² is required. But you should pay attention to the brightness adjustment function. For example, a shopping mall should be bright during the day, but it would be too dazzling at night to be annoying. There is a little trivia:​ ​Low brightness and high gray technology​ ​It can prevent the color of the screen from turning white when the brightness is turned down. This is a touchstone to test the technical strength of the manufacturer. The refresh rate is 1920Hz or higher, so you can watch live racing without smearing. Businessmen generally don’t dare to falsely mark this parameter. You can try it out by taking a slow-motion shot of the screen with your mobile phone.

Application scenarios are the key to spending money. The installation of outdoor advertising screens depends on the protection level, and IP65 is the basic threshold. If it rains, the screen will be short-circuited due to water intrusion. If the advertising fee is not earned, maintenance fees will have to be paid. If it is installed on the stadium fence, you must choose a box with an anti-collision design. If a player bumps into it, the screen will be fine. If the lamp beads are damaged, they can be replaced individually. Don’t underestimate the maintenance cost. For some screens, you have to dismantle the entire module to replace the lamp beads. The labor cost is more expensive than the parts.

Speaking of this, someone must have asked:​ ​The price is several times different. What is the difference?​ ​? Let's take it apart and see: whether the chip is imported or domestic, whether the lamp bead packaging process is surface-mounted or film-coated, whether the power module has overload protection...these details add up to the cost gap. For example, for a screen with the same P3 pitch, using a common cathode driver can save 30% of power than a normal driver, and the difference in electricity bills over three years will be a fraction. However, novices are easily fooled by "low price and high configuration". Remember this sentence:​ ​For screens with similar parameters, a price difference of less than 20% is normal. A price difference of 50% is definitely something fishy.​​。

Finally, let’s talk about the hidden cost of after-sales service. Some manufacturers disappear after selling the screens. If there is a problem, you have to find a third party to repair it yourself. Reliable manufacturers are involved from the beginning of installation and debugging, and provide technical response within 24 hours in case of emergencies. You must know that if the screen goes dark for half an hour during an event in a shopping mall, the loss is much more valuable than the screen itself. Pay attention to whether the after-sales terms include services such as remote diagnosis and spare parts in advance. Don’t just listen to verbal promises.

In the final analysis, choosing an LED electronic screen is not about comparing parameter tables, but about comparing​ ​Stable performance in real application scenarios​ ​. The next time I go to see a sample, I will play the 4K test video source live, stare at the high-speed motion picture to see if there is any smear, stand on the side to see if the color is correct, and touch the heat dissipation holes with my hands to see if the temperature is high. These native methods are much more effective than listening to salesmen talk about PPT. Remember, a good screen can withstand the test of time. If it lasts three years without any problems, then it is truly reliable.
