Dear bosses, have you ever noticed the display screens that are curved like ribbons in the mall? Or the slender indicator screen in the subway station? This is the protagonist today - the LED bar screen! Don’t look like a stick, it will be much more fragrant than a traditional screen if used correctly!

1. These places are being dominated by bar screens"

Let me take you to see how popular this thing is now:

​​1. Transformation of commercial space​​

• ​​Shopping mall atrium sky​​: A 20-meter-long curved strip screen surrounds the glass dome, which is decorated during the day and changes to the starry sky at night
• ​​Shop killer​​: A 1.2-meter-high narrow strip screen replaces traditional light boxes and can broadcast dynamic promotional advertisements
• ​​Shelf information bar​​: 30cm wide mini strip screen embedded in the edge of the shelf, price updates in real time

For example, a department store in Seoul used this kind of screen, and the time for customers to find products was shortened by 40%, and sales increased by 15% [user information].

​​2. The new favorite of transportation hubs​​

• ​​Subway Tunnel Animation​​: A 200-meter-long screen forms a dynamic scroll, and passengers no longer feel that the tunnel is long
• ​​Airport check-in guidelines​​: The hanging strip screen looks like a streamer in the air, changing color as the flight information flows
• ​​Highway Intelligence Board​​: The strong light-resistant strip screen shows the road conditions, and the driver can see clearly 500 meters away

The bar-screen project at a subway station in Tokyo directly killed 70% of the number of times passengers asked for directions [user information].

2. Three soul-questioning questions about buying a bar screen

​​Q1: Is it the finer the better? ​ ​
wrong! Common widths are 80mm, 120mm and 150mm:

• 80mm is suitable for decorative lines (such as window frames)
• 120mm universal size (information display + basic advertising)
• 150mm suitable for long-distance viewing (sports stadium)

Remember this formula:​​Optimal viewing distance = screen height × 30​​

​​Q2: How to choose brightness without overturning? ​ ​
Teach you a trick:

• Indoor selection of 800-1200cd/m² (it is almost the same as the mobile phone screen)
• Semi-outdoor requires 2000-3000cd/m² (prevent direct sunlight)
• All outdoors can start from 4000cd/m² [user information] (the same level as car headlights)

There is a milk tea shop owner who bought a low-bright screen with a cheap picture, but the picture was not visible during the day, just like a blackboard hanging!

​​Q3: Will the house be demolished when installed? ​ ​
There are three mainstream installation methods now:

• ​​Hoisting type​​: Like hanging curtain rods, suitable for spaces with a floor height of more than 4 meters
• ​​Embedded​​: Inlaid directly in the wall or cabinet, saving the most space
• ​​Column type​​: It comes with a support frame, you can sway wherever you want

The curved lifting screen we made for a shopping mall in Singapore was installed in half a day for 8 people, saving 60% time than the traditional screen [user information].

3. I've stepped on these pitfalls for you

​​1. Waterproofing ≠ everything goes well​​
Don’t look at the parameters that say IP65 protection [user information], install "Rain Eyebrow" when it is raining. A hot pot restaurant put the screen under the eaves, but the steam condensate water soaked the circuit board.

​​2. Maintenance passages must be reserved​​
Don't pretend to be dead when you stick to the wall! Leave at least 15cm of space behind. Because there is no maintenance port in a supermarket, the entire shelf needs to be removed if the cable is replaced.

​​3. Content adaptation is the way​​
Don't use square screen materials directly! Remember these two ratios:

• Vertical screen: 9:16 or 3:4
• Horizontal screen: 32:9 or 16:3
  A bar owner stretched the video material directly, but his face was deformed and the customer complained that he looked like a mirror

Personal opinion time

After working in the display project for more than ten years, I found that the bar screen has now changed from a "supporting role" to a "space magician". Just like the luggage carousel guide screen we made for an international airport, it can not only display flight information, but also distinguish luggage priority by colors. This is the real smart display.

Those manufacturers who are still competing for prices will be over sooner or later. The future bar screen needs to play with these new tricks:

• Flexible screen that can be retracted and placed like a scroll
• Interactive bar screen with touch feedback
• Smart screen that automatically changes content based on the flow of people

Remember, a good screen should not only be beautiful, but also "understand the scene" - after all, no one is willing to spend money to buy an electronic stick that only knows how to put PPT. Do you think this is the case?
