Are you worried about the LED advertising quotation lists on the screen? For display screens of the same size, this one charges 80,000 yuan and the other charges 150,000 yuan; the same as saying that the warranty is three years, some people will get a problem in half a year. Today we will talk about it-​​Buying a commercial LED screen is like finding a partner. Just looking at your appearance is not enough. You have to find out the details!​​

1. Choose a supplier and avoid 90% of the pitfalls

Last month, I helped my friend inspect the shopping mall large screen, and the supplier was so full of excitement, but the color block fault occurred after three days of installation. Here is a reminder for you:

​​1. Qualification certificate is hard currency​

• Look at three certificates: ISO9001 is the basic threshold, CE certification represents export quality, and CCC certification ensures safety
• Manufacturers with monthly production capacity of over 10,000 square meters are more reliable (large production line size = mature technology)
• Take a look at a chestnut: A Japanese convenience store chain specializes in choosing such suppliers, but has not changed the screen in five years

​​2. The case library contains real kung fu​​

• Don't just look at the renderings, you need photos of the construction process
• Focus on cases in the same scenario: Shopping mall hoisting and outdoor columns are completely different
• There is a trick - let the supplier provide case videos that have been running for two years to see if there is any color loss

​3. The service network must be dense enough​

• The technical team that responds 24 hours a day is a must
• Focus on checking whether there are local service outlets (the sudden black screen cannot be repaired for two hours, and the passenger flow can drop by 30%)

2. How to choose and remember these three sets of passwords in different scenarios

Last week, I went to the Electronic City and found a strange phenomenon - the stall selling lamb skewers actually installed P2.5 small-pitch screen! It's like driving a tractor to run on the highway, it's a waste.​​Commercial screens emphasize the right match​：

​​1. Outdoor advertising screen​

• The brightness must be strong enough: start at 5000nit, and the sunlight can be suppressed at noon
• Protection level IP65 is the bottom line (storm and hail are made at will)
• I have a cold knowledge: a screen with smart dimming can save 40% of the electricity bill in a year

​​2. Shopping mall digital signage​

• Refresh rate ≥1920Hz, no flickering stripes when shooting short videos
• Choose a matte mask, anti-reflective and dazzling
• The smartest solution I've ever seen - automatically switch content based on traffic

​3. Stage rental screen​

• The box should be lighter (aluminum-magnesium-zinc alloy is 30% lighter than iron shell)
• Quick disassembly and assembly design, can build a background wall in two hours
• Last year, a music festival used quick screen removal, and the equipment was collected 20 minutes before the heavy rain

3. Procurement negotiations have three tricks to bargain without compromising quality

Lao Wang's hot pot restaurant suffered a big loss last year - the bargaining price was too fierce, and the screen installed was lit up like a searchlight at night. Here is a guide to how to bargain elegantly:

​​The first axe: Compare the material list​​

• The brand of lamp beads should be stated (some big-brand lamp beads have a lifespan of 100,000 hours)
• The power supply must be backed up by dual channels (the power is off and switched to 0.3 seconds is the real insurance)
• Case: A chain of hotels insists on importing power supplies, with zero failures in five years

​​The second axe: warranty terms​

• Human damage is also required (it is too common for shopping mall cleaning to damage the screen)
• Add an additional night emergency service clause (add 5% but it is worth the fare)
• The most conscientious one I have ever seen - three years of free home dust removal

​​The third axe: Value-added services​

• Receive half a month of advertising content production
• Training two operation and maintenance personnel for free
• A gym is about to see a linkage display plan for body fat data

Personal opinion time

After more than ten years in this industry, LED screens have changed from luxury goods to fast-moving consumer goods. Say something heart-wrenching:​Buying screens now is not buying equipment, but buying solutions​​. A good supplier can help you settle the account - for example, the electricity bill saved by using energy-saving screens is enough to replace new equipment in three years.

I have recently discovered a new trend—​​Smart screen is eating the cake of traditional advertising space​​. For example, some shopping malls can recognize crowd characteristics and automatically push maternal and child or car advertisements, and the conversion rate will be doubled directly. Next time you purchase, you might as well ask if this function is available.

Finally, I would like to remind all the bosses:​A good screen is like a good employee—there is a reason why it is expensive​​. Don’t just focus on the unit price. Calculate the maintenance and electricity bills within five years. Sometimes it’s more cost-effective to spend 20,000 more. Remember, the pitfall of commercial screens is not in the price, but in the invisible place!
