Recently, I have received a lot of inquiries from novices: I want to invest in a large LED screen in the East Third Ring Road of Beijing, but faced with an advertising budget that can easily reach millions, how do I choose to avoid wasting money? To be honest, choosing the right placement and screen parameters can save 30% of advertising costs. Let’s break it down today and talk about the location selection tips that businesses won’t tell you.

​​Three hidden data of prime locations​​
Don't just listen to imaginary numbers like "average daily traffic flow of millions", what you really want to focus on is​ ​Effective exposure time​ ​. The average parking time of vehicles in the area of ​​Jingxin Building is 35 minutes, which means that drivers have enough time to see the advertising content clearly. White-collar workers in the surrounding 5A office buildings have the opportunity to see large screens through floor-to-ceiling windows at least 6 times a day.

​​Transmittance ≠ display effect​​
Many novices are easily fooled by "86% light transmittance". In fact, they need to be combined with three parameters:

1. ​​Pixel pitch ≤P6​ ​(Guaranteed clarity from 5 meters away)
2. ​​Refresh rate ≥1920Hz​ ​(No ripples appear when shooting video)
3. ​​Automatic brightness adjustment range 4000-7500cd/m²​ ​(Coping with morning and evening light changes)
   Last year, a milk tea brand chose non-standard products for cheap. As a result, the advertisement was completely unclear at noon, and three months of rent were wasted.

​​There is a 20% price difference hidden during the delivery period​​
Don’t rush into signing a full-year contract, do it first​ ​72 hours on-site monitoring​​：

• Morning rush hour (7:00-9:00) traffic flow crowd attributes
• Office building exposure during noon (11:30-13:30)
• Evening peak (17:00-19:00) commercial passenger flow conversion rate
  A certain car brand found through monitoring that the conversion rate of screen exposure increased by 40% after 7 pm on weekdays, so it decisively adjusted the combination of delivery time periods.

​​Maintenance costs account for a hidden 15% of the budget​​
Be sure to confirm when selecting a screen:
✔️ Protection level starts at IP65 (can withstand sandstorms in Beijing)
✔️ Quick disassembly and assembly design of the box (sudden failure can be repaired in 2 hours)
✔️ Three-proof treatment for driver IC (moisture-proof, anti-static and anti-salt spray)
The worst case I have ever seen - a businessman did not pay attention to the heat dissipation design. As a result, the screen overheated and became discolored in midsummer, and the maintenance fee was higher than the annual rent.

​​Three verification methods that novices must read​​
Teach you three ways to check authenticity:

1. Need screen​ ​Factory aging test report​ ​(No bad pixels for 72 consecutive hours)
2. check​ ​Maintenance records in the past three months​ ​(Monthly failure rate ≤0.3% is considered qualified)
3. pilot​ ​15 seconds dynamic video​ ​(High-speed images without smearing are considered up to standard)
   Remember, a reliable supplier is one that dares you to use a photometer to test brightness uniformity on site. Those who are only allowed to watch promotional videos are probably hiding something fishy.

Now you understand why some brands would rather spend 20% more budget to choose customized solutions, right? The surrounding Fortune 500 companies all adjust their broadcast strategies on a quarterly basis. Pay attention next time you pass by the Kingxin Building - the brightness of the screen showing financial advertisements in the morning will be reduced by 15%. This saves power and is not dazzling. The details are the real work.
