I heard that a certain Internet celebrity bar in Shanghai just replaced three screens. As a result, the resident singer was always dazzled by reflections when performing? This reminds me of a little trivia:​ ​One out of every five LED screens in the bar is installed in the wrong place​ ​. Last month, I dismantled the equipment of a closed bar and found that the control card was corroded by alcohol and turned green. Do you think this money was spent unjustly?

1. Three iron rules for installing screens in the bar area

The screen behind the bartender serves as a facade, but many bosses fall short on basic parameters:

1. ​​Choose 800-1200cd/m² for brightness​ ​: Too bright looks like a searchlight, too dark looks cheap
2. ​​Protection grade at least IP43​ ​: Can prevent drinks from being spilled, can withstand smoke and fire
3. ​​Refresh rate must be ≥1920Hz​ ​: There will be no ripples when shooting Douyin

The owner of a music bar in Hangzhou complained to me: I bought an ordinary screen at a cheap price, but when the singer shook his head, the screen was full of smear. After switching to a high-refresh screen, the number of hair ties taken by customers has doubled. It’s money well spent!

2. Hidden levels on the dance floor tile screen

A nightclub in Shenzhen suffered a hidden loss - the floor tile screen was crushed by high heels, and the repair fee was enough to buy a motorcycle. Here are some tips to prevent pitfalls:

• Surface load-bearing requirement ≥800kg/㎡
• The protection level must be IP65 (can withstand alcohol immersion)
• ​​focus​ ​: Choose the model with anti-glare coating

There is a real case: After a bar in Chengdu replaced the screen with a hydrophobic coating, the cleaning hours were reduced from 3 hours to 20 minutes a day. The labor cost saved is enough to host two more theme parties every month.

3. The size of the screen in the booth area

Don't believe the "bigger is better" nonsense! Actual measured data shows:

• The two-person booth is suitable for 32 inches (viewing distance 1.2 meters)
• The four-person deck starts at 55 inches
• VIP boxes must be 86 inches or above

A business club in Beijing tried to install the wrong size. As a result, guests complained that they felt dizzy. After later adjusting according to the sight distance ratio of 1:3, the average consumption of alcohol increased by 18%.

4. Tips for saving money on repairs and maintenance

The owner of a Qingdao bar in Guangzhou calculated that choosing the right equipment can save 40% of maintenance fees. Remember these three time points:

• Do grayscale calibration on the 1st of every month (to prevent color shift)
• Dismantle and clean dust every quarter (double in humid areas in the south)
• Change the moisture-proof bag every year before the rainy season

Here’s a trick: choose a screen with a modular design, and replace whichever unit is broken. Last time I saw a master, he repaired an 8-square-meter screen in 10 minutes, which saved 3 hours of labor compared to the traditional method.

Let me tell you, the screens in bars are no longer just simple display tools. Last year, I saw a transparent screen in Chongqing. It acts as a floor-to-ceiling window during the day and turns into a display screen at night. This kind of black technology will be popularized sooner or later. Next time you go to a bar, you might as well touch the screen frame. If it's hot to your hands, it's probably time to upgrade the equipment in this place!
