Have you encountered this situation? After driving into the shopping mall parking lot for 20 minutes, I couldn't find the parking space. Finally, I saw the induction screen showing "the remaining 5 digits". But when I drove in front of me, I found that it was already full? What’s even more annoying is that some screens reflect severely during broad daylight and cannot see the numbers clearly. Today, let’s talk about the LED parking induced screen. You will be more professional than 80% of property managers after reading it!

​​Must-read for beginners: Three iron rules for purchasing​​

Last month, a shopping mall owner complained to me that he spent more than 100,000 yuan to induce screens, but it would be spent on rainy days. The problem lies in​ ​Protection level​​On this indicator. In an environment like an underground garage, you must at least choose IP54 protection. ； If it is an open-air parking lot, it must be at IP65 level. There is a particularly typical case: a commercial body in the south crazily installed an ordinary screen, but the water inlet was short circuit during the rainy season, and the maintenance fee alone cost 80,000 yuan.

Let's talk about it​​Brightness adjustment​​This matter. Have you ever seen the screen as dark as if it wasn't turned on at noon? It is recommended to choose an indoor parking lot of 800-1200cd/m², and the open-air environment must reach 4000cd/m². There is a fixed brightness screen used in a community parking lot. It was dazzling at night and the owner complained that the power was cut off overnight.

The third focus is​​Refresh rate​​. Don't consider screens below 1920Hz - digital jumps will drag when the vehicle moves. Actual test data shows that the high refresh rate screen allows drivers to discover parking spaces 2.3 seconds in advance, especially during peak traffic periods, this time difference can reduce channel congestion by 30%.

​​Hidden costs in installation and maintenance​​

Maybe you will ask: "If you buy a good screen, everything will be fine?" "Alas, here's a point of focus——​ ​Box structure determines late costs​​. Scaffolding is required for installation of traditional steel structures, and the new aluminum-magnesium-zinc alloy quick-release box saves this money directly. The single box is only 8.6kg, so you don’t need to clear the floor during maintenance. You can change the module as soon as you put the ladder. According to a certain project, the maintenance efficiency of 200 parking spaces has been directly increased by 6 times.

How to save electricity bills? For example: a screen with intelligent dimming function can save 37% of the monthly electricity bill. This is not a boast. A logistics park compared it with the same screen, the smart model has a 28,000 yuan less electricity bill per year.

​​Pit avoidance guide: parameter comparison table​​

Another invisible indicator is​​Perspective range​​. Some screens look clearly from the front, but reflect on the side. It is recommended to choose a horizontal viewing angle of ≥160° so that the vehicle can also see the information clearly when turning.

​​Technical flow analysis: What kind of black technology is low brightness and high gray? ​ ​

You may be curious: "Why are the inducing screens in high-end shopping malls not dazzling at night? "The mystery is​ ​Level 4096 grayscale control​​. When the brightness of an ordinary screen is lowered, it will make the numbers at 20% brightness still clear. The actual data shows that the screens using this technology are in a dim environment in the garage, and the information recognition rate is increased by 73%.

There is a particularly typical case: after a hospital garage uses this technology, the time for patients who visit the hospital in the middle of the night to find a parking space was reduced by 40%, and dispute complaints were directly reduced by 60%.

​​Hard indicators for global verification​​

Check out these measured data:

• Thunderstorm environment continuously operates for 2000 hours zero failure
• -25℃ to 65℃ extreme temperature displays normally
• 7500cd/m² peak brightness is not dazzling
  These are not laboratory data, but real skills that have been verified by strict environments in Tokyo, Seoul and other places.

​​Editor's opinion​​
Now I know how to choose the LED parking induced screen? The key depends on the manufacturer​ ​Is the monthly production capacity exceeding 10,000 square meters​​、​​Is there any full-process quality inspection?​​. I heard that some small workshops do not even perform aging tests, and this kind of screen will definitely cause trouble after half a year. Next time you visit the supplier, remember to touch the box joints - the workmanship is rough, and the waterproof performance will definitely be discounted!
