Have you always seen the kind of display screen like blinds when visiting shopping malls recently? It can not only play dynamic advertisements, but also prevent store lighting. This kind of black technology isLED grille screen​. But the question is - nine out of ten bosses who want to install this kind of screen are asking: "Where to buy this kind of hollow display screen? The manufacturers found online look similar, and the price is too different to buy a car!"

1. Why are grille screens so popular?

This thing is not a variant of an ordinary LED screen. The traditional display screen is installed on the glass curtain wall, either blocking the light and being complained by the merchant, or reflecting the contents cannot be seen clearly.​​The grille screen is just awesome​：

• The maximum permeability can reach 75%, and the installation of the shopping mall atrium will not delay lighting
• The thickness of a single light strip is only 22mm, and it looks like a metal decorative strip from a distance.
• Module spacing can be adjusted, P20 to P50 switch display accuracy at will

To give a real case: A business district in Seoul has installed two rows of grille screens, which are decorated during the day and become a flowing light and shadow gallery at night. This dual-purpose design has increased the rent of shops by 15%.

2. Depend on these three points

Don't be fooled by the sweet words of sales,​Touch these three places​：

1. ​Light bar seams​: After splicing high-quality products, there is almost no gap, and your nails are scratched without scratching your hands
2. ​​Heat dissipation hole​: For real materials, you can use CNC to accurately drill holes, and the aperture error is ≤0.1mm
3. ​Power box​: Waterproof level is at least IP65, it is even heavier than a mineral water bottle

Once I went to the supplier warehouse to inspect the goods and found something outrageous - the light strips for a batch of goods were actually fixed with double-sided tape! This screen is installed with three months of deformation, and it sways like a draped noodles when the wind blows.

3. The golden rule for finding a manufacturer

Now I know how to inspect the goods,Where can I find a reliable source factory?​? Teach you four tricks:

• Watch the production line video: No direct pass in the dust-free workshop
• Aging test report: High temperature test is considered qualified for 48 hours in a row
• Export qualification check: A manufacturer that can be a Japanese and Korean market, with at least three strict quality control
• Trial dynamic screen: Focus on the red display effect, inferior screen will make powder

Details only an expert knows--​​The real good screen dares to use pure white background demonstration​​. Those who only show you dark demonstrations are mostly covering up the problem of uneven brightness.

4. How to break the price fog?

The same 10 square meters P25 grille screen has a price ranging from 80,000 to 300,000. The price difference is mainly in these parts:

1. ​Lamp bead chip​: The ones that use Privilege chips are 40% more expensive than miscellaneous brands, but their lifespan is 20,000 hours more
2. ​Structural Materials​: Aviation aluminum and galvanized iron sheets have two typhoon levels of wind resistance
3. ​Control System​: It can be controlled independently in regions, 1.5 times more expensive than ordinary systems

It's more intuitive to see this comparison table:

Pay special attention to the installation fee. Some manufacturers quote low prices but calculate the lifting fee to 200 yuan/square meter, and 10 square meters will have to add another 2,000 yuan.

5. Installation location determines life and death

It's not that everything will be fine if you buy the screen,​Installation of the wrong place turns into scrap iron in minutes​：

• ​​Mall Atrium​: Select P30-P40 spacing, and the brightness is controlled within 1200cd/m²
• ​Building facade​: It must have intelligent brightness adjustment, and it will automatically adjust to 30% brightness in the middle of the night
• ​Airport Terminal​: It is necessary to prevent electromagnetic interference certification and do not affect the navigation system

The most professional installation team I have ever seen, with a laser rangefinder adjusting the level, and the height difference between the two sides of the 10-meter-long screen is no more than 3mm. This kind of accuracy is simply impossible for ordinary construction teams to do.

The editor finally said the truth: finding an LED grille screen supplier is the same as finding a decoration team. Next time I meet someone who is so singular, I will ask him directly if he dares to sign.​Five-year warranty contract​. Remember, the seams of a good screen are finer than those of a mobile phone screen, and the solder joints of a bad screen seem to be gnawed by a dog. Next time I go shopping, pay attention to the grille screen of the mall and look closer to the seam - there is the supplier's conscience hidden there!
