Friends who just opened a bar are always confused: Who should I buy the cool display screen at the bar? Last year, there was a newly opened livehouse in Hangzhou. The boss spent 80,000 yuan on the device, but the screen brightness was not enough and the customer complained. Don’t worry, today we will dismantle the bar display screen selection path.

​​See a real comparison:​​
A popular internet wine bar spent 72,000 yuan to install the dance floor tiles screen, which was repaired 4 times in half a year ； Another store that uses the right method has only spent 48,000 screens in the same size, and has zero failures in two years. What's the difference? Choosing the right supplier is too critical.

▍Three golden channels for finding merchants

1. ​​Renovation company resource pool​ ​: 80% of high-quality installers are hidden in the design company's cooperation list. Remember to copy the "Blank List of Audio and Video Equipment" when discussing decoration next time
2. ​​Industry exhibition appearance​ ​: Events like Guangzhou Lighting and Audio Exhibition can be directly seen in the boot demonstration effect. Remember to take a photo of the manufacturer's CCC certification code
3. ​​Reverse tracking of fault screens​ ​: Observe the old screen replaced by competitors, the production date and manufacturer code on the nameplate will talk

Last month, I wandered around the bar street in Shenzhen and found three stores that were replacing display screens, two of which used goods from the same OEM factory - this kind of cluster procurement often gets wholesale prices.

▍Cost black hole warning list

Last week, I just found a case for a friend: the "full waterproof" written on a quotation actually only sprayed with moisture-proof coating. For a truly IP54-protected screen, there must be a rubber seal ring + drainage hole design at the interface.

▍20-year-old cannon's procurement secrets

1. ​​It is better to ask for a case than to ask for a sample​ ​: Let the merchant provide installation cases of 3 city bars and go directly to the site to see the night effect
2. ​​Bargain first​ ​: Change "five-year home maintenance" to "three-year insurance + remote guidance" to save 15% of the budget
3. ​​Payment installment is a priority​ ​: It is recommended to adopt the 3331 model (deposit 30% + arrival 30% + debugging 30% + warranty 10%)

There is a tough trick for you to remember: ask suppliers to provide "Brightness Decay Test Report". After 5,000 hours of use of screens from regular manufacturers, the brightness attenuation should not exceed 15% - this can screen out 60% of inferior products.

▍7 things to do on the installation site

1. Touch the power module with the back of your hand during power-on test (stop immediately if it becomes hot)
2. Check whether the control card number is consistent with the contract list
3. Use your phone to shoot slow motion videos to check refresh rate
4. Sprinkle half a cup of beer to test the surface corrosion resistance
5. Test the display effect at the lowest brightness at 2 a.m.
6. Deliberate power outage and three times to observe restart stability
7. Let the bartender operate the playback system on-site

The most exaggerated case I have ever seen: the circular screen of a bar splashes every Friday night, and later it was discovered that it was caused by the instability of the voltage on weekends. Now the smart power module can automatically adjust voltage fluctuations, and the price is only 800 yuan.

▍These parameters determine life and death

• ​​Brightness Trap​ ​: It’s not that the brighter the better, it should be selected according to the illumination of the spotlight on the bar (calculation formula: screen brightness = ambient illuminance × 1.5)
• ​​Refresh rate blind zone​ ​: At least 3840Hz is required to shoot cocktail-made videos, otherwise the phone will be full of water ripples.
• ​​Curvature metaphysics​ ​: The bending radius error of the arc screen exceeds 5%, visual distortion will occur

There is a data you can remember: in 2023 bar equipment complaints, 67% of the problems lie in the incompatibility of the control system. When selecting the screen, be sure to bring a USB flash drive to test the playback effects of various video formats on-site.

Finally, let me talk about cold knowledge: a boss who truly understands the situation will choose a model with a smart photosensitive module. This screen can automatically adjust brightness according to passenger flow, saves power by 38% during peak season, and extends the screen life span in the off-season - this is the money tree function hidden in the parameter table.
