Do you often see cool advertising screens on the exterior walls of shopping malls, but don’t know what they are called? Or at the concert, I was amazed by the transparent stage background, but I couldn’t figure out what kind of black technology this is? Don't worry, today we will talk about this one that makes architecture and stage "live"​Grille LED display——After reading this article, you will surely go from "not knowing nothing" to "half an expert"!

1. What is a grille screen?

Simply put, this is​The hollow display screen made of light strips​​, like blinds, it can be transparent and air-transmitted. The biggest difference between it and traditional LED screens is that traditional screens are "iron plates", while grille screens are more like "screen windows". This structure gives it three killer weapons:

1. ​​Obsolutely light​: Ordinary screens are often 50 kg/square, and grille screens are only 15-20 kg. You are not afraid of crushing them when hung on the glass curtain wall.
2. ​​Breathable and light-transmissive​: 85% permeability means that the installation will not affect the lighting of the building, and the wind can pass through the gap.
3. ​​Can concave shape​: Arc, wavy, and special shape splicing are all not a problem

2. Where do you need this thing the most?

​​Mall exterior walls​​: For example, the jewelry store windows must display advertisements and not block the product. At this time,​86% transmittanceThe grille screen is perfect
​​Sports Stadium​: Install a circle of screens on the fence, which can both broadcast scores and serve as an advertising space. The key is to withstand the wind and rain, and you must chooseIP65 protection levelOf
​Stage performance​: Last year, a celebrity used a removable ice screen, the entire screen weighs only half of the conventional screen, and you are not afraid of being blown away during typhoons.

Here is a hard knowledge - you have to look at the grille screenPoint spacing​：

• P3.91: Suitable for 20 meters of viewing (large stadium screen)
• P15.6: Suitable for viewing 5-10 meters (mall exterior wall)
• P31.25: Suitable for long-distance advertising (highway)

3. The 5 most common pitfalls for beginners

1. ​​Only look at the price, no matter the certification​: Certificates such as CE and CCC are like mobile phone access licenses. Screens without these may be cancelled after half a year.
2. ​​Ignore the installation environment​: The seaside cities must choose to protect against salt fog, the north must resist low temperatures, and the south must protect against moisture.
3. ​​The wrong brightness is selected to destroy everything​: It will be dazzling when using 3000cd/m² indoors, but it will be impossible to see clearly when using 800cd/m² outdoors.
4. ​Don't understand maintenance costs​: Some screens need to remove the entire board if they change the lamp bead, choose supportPre-maintenance designIt can save a lot of money
5. ​​Believe in "universal screen"​: No screen can take all the scenes, customization is the king

To give a real case: A shopping mall installed a batch of grille screens last year, but because of no load-bearing testing, the structure deformed in three months, and finally all of them were reworked and reinstalled. So remember-​—​​Be sure to measure the wall load bearing before installation​​！

4. Soul interrogation time

​​Q: Is the grille screen easier to break than the ordinary screen?​​
A: Quite the opposite!​​The hollow structure is more heat-dissipating​, it will be fine if you use it normally for 5-8 years. The key is to choose a good glue filling process and wrap the circuit board tightly to prevent oxidation.

​​Q: Will there be electricity leakage on rainy days?​​
A: All qualified screens are​Double protection​: The outer layer IP65 is splash-proof, and the internal circuit is triple insulation. However, remember to ask the master to do a good job of grounding when installing

​​Q: Is repair particularly troublesome?​​
A: Now all new models are supportedModular repair​, change whatever is bad. For example, some high-end models can be replaced in 15 minutes, which is faster than repairing a mobile phone.

5. Purchase secrets that experts know

1. ​​Light beads need to identify the brand​: Also speaking of using the National Star Lamp Bead, the price difference between the real product and the imitation product can be 30%, and the life span is 3 times different.
2. ​​Don't save a little money on the power supply​: Mingwei power supply is 50% more expensive than miscellaneous brands, but it can be used for 10 years without burning the board
3. ​​Structure depends on details​: The thickness of the aluminum alloy frame is at least 2mm, and the splicing gap must be <0.5mm
4. ​​Don't be lazy in the test​: Be sure to do a 72-hour aging test before receiving the goods to see if there is any dead light color shift
