Do you often see such scenes? The advertising screen at the entrance of the mall was broadcasting milk tea promotion, and passers-by raised their phones together ； The scrolling screen at the subway entrance was replaced with new property information, and people waiting for the car looked up with their necks. I feel itchy and want to make a whole piece of my own store? Don’t worry, let’s talk about this trick today - from street hardware stores to professional manufacturers, the water here is deeper than you think.

​​1. First understand these 3 parameters and spend less money​​
Last week, a man who runs a hot pot restaurant complained to me: "I bought a screen for 30,000 yuan, and it looks like I was mosaic during the day." In fact, choosing a screen is like fitting a computer, you have to see these hard indicators:

• ​​The brightness must be ruthless​​: It is impossible to see clearly at noon below 4000cd/m², but it is scary at night above 7500cd/m² (reference value: the direct sunlight intensity at sunny noon is about 100,000cd/m²)
• ​​Don't change the refresh rate​​: 1920Hz is the bottom line, otherwise the video shooting is full of ripple - you don’t want customers to shoot Douyin to bring their own water ripple effects, right?
• ​​Depend on the protection level​​: IP65 is a standard outdoor equipment, and you don’t have to worry about wind or rain. The most outrageous case I have ever seen: A milk tea shop uses IP43 on the screen, and smoke comes out when it rains lightly

Key points: Let the seller demonstrate on-site demonstration and use his mobile phone to shoot screen videos, and then discuss the price without ripple.

​​2. The hidden secrets of purchasing channels cannot be stepped on.​​
Do you think it is cheapest to find a manufacturer to sell directly? A chain brand suffered a lot last year:

1. ​​Online platform​​: The price on Taobao is 20,000 yuan per square meter. It was found that it was a refurbished module (the maintenance cost was 18,000 yuan more)
2. ​​Second-hand market​​: It is known as 90% new screen. If you disassemble it, you will find that the driver chip is a model 5 years ago (the compatibility is so poor that it hurts)
3. ​​Bag company​​: The contract said "three-year warranty", but the company was cancelled after half a year

Reliable method: It is required to watch the factory's real-time videos in the workshop, and the video should have the newspaper of the day as the background. I have met a smart boss and asked the salesperson to video call in front of the assembly line to inspect the goods.

​​3. There is a need to choose the wrong location and choose the wrong location.​​
Don't think it's all done if you buy it and install it! Last year, the owner of a hot pot restaurant put the screen under the shade of the tree, and the result was:

• In summer, leaves blocked, local overheating (12,000 yuan was spent on three repairs)
• In winter, branches are frozen and smashed with lamp beads (insurance refuses to compensate)

Golden site selection rules:

1. Avoid direct afternoon light from the south (it is recommended to install 15° eastward)
2. The height above ground is 2.5-3 meters and the most eye-catching (refer to the height of the bus stop)
3. There are also high-power electrical appliances within 3 meters of the surrounding area (be careful of electromagnetic interference)

There is a cold knowledge: if you install a screen near a bank or government unit, the customer trust level will automatically +30%.

​​Ask and answer core questions​​
Q: Why is the price difference between the same size screen quotation 3 times?
A: Maybe the brand of lamp beads is different. For example: the unit price of a large international manufacturer, the unit price of a lamp bell is 0.08 yuan, and the miscellaneous brand is only 0.03 yuan, but the life span is more than 5 times. Teach you how to inspect goods: Use a utility knife to lightly scrape the surface of the lamp beads, and the good products have a scratch-resistant coating.

Q: What should I do if I can’t install it after I buy it?
A: Nowadays, regular manufacturers all carry out installation and debugging. The focus is on whether the contract has written "structure mechanical calculations" - a gym did not perform load-bearing tests last year, and after installation, it lost 280,000 yuan after cracking the exterior wall after three months of installation.

Q: How to determine the actual screen size?
A: Don’t believe in the “60-inch” statement, the outdoor screen must be calculated in square meters. Remember this formula: display area = length (meter) × width (meter). For example, if you want to display a complete portrait, you must at least 1.8m×1.2m.

​​The blood and tears experience of people who have experienced it​​

1. The contract must be signed with "lightning protection module" (don't ask me how I know)
2. Be sure to play pure white screen for 5 minutes during the test (quickly find out the dead light)
3. Set aside 10% budget for backup modules (repair and other accessories are too delayed in business)
4. Wipe the screen at 9 am every Wednesday (there is the minimum passenger flow during this period)

Finally, let’s be honest: buying an outdoor advertising screen is like finding a partner. You can’t just look at the appearance parameters. After-sales response speed is the key to life. The most responsible manufacturer I have ever met, received a repair call at 2 o'clock in the middle of the night, and the engineer arrived in one hour with the accessories - it is worth spending more money on this kind of service!
