You must have seen this scene: the LED screen at the entrance of the shopping mall is gray in broad daylight, and the sign screen at the subway station is so crooked that it is impossible to read the words. Last year, my neighbor opened a restaurant and spent 80,000 yuan to install a dot matrix screen. However, because it was installed on the back of the glass window, the reflection was so severe that even the menu prices could not be seen clearly. Today we are going to talk about this bald issue - how to choose the location of LED dot matrix screen?

​​Installing in the wrong location means burning money. Understand these three parameters first.​​
Don’t be in a hurry to measure the size. Carve these three data on your forehead first:

1. ​​Viewing range​ ​: A screen with a vertical viewing angle less than 110 degrees is seeking death if it is installed at a height of more than 3 meters.
2. ​​ambient illumination​ ​: The brightness of the outdoor screen is less than 4000 nits, which is basically the same as a blackboard under noon sunlight.
3. ​​Protection level​ ​: The dining area must be at least IP54 anti-oil pollution, and the surrounding areas of the construction site must be IP65 starting

Last week I went to inspect a gym project and found that they​ ​Naked-eye 3D screen​ ​Installed at the corner of the locker room passage, the viewing distance is only 0.8 meters, a perfect dizziness-making machine. Remember, for small-pitch screens below P2.5, the optimal viewing distance is three times the screen height.

Comparison table of five types of golden points

I made a scene adaptation table, and novices can copy the homework directly:

Let’s focus on the pitfall of the stadium fence screen. Last year, a basketball stadium used an ordinary screen as a fence screen. When athletes bumped into it, it was completely black. Serious fence screens are useful​ ​Magnesium alloy back plate​ ​, can withstand the impact of a 200-pound man.

Don’t try these four ways to pretend to be dead

1. ​​Ordinary screen installed directly opposite the glass curtain wall​ ​: Reflective light can eat up all the displayed content.
2. ​​Fire exit fixed frame screen​ ​: Block the escape route in an emergency
3. ​​Install a screen with poor heat dissipation at the kitchen outlet​ ​: Oil smoke can cover the cooling holes in three months.
4. ​​Right-angle screen installed in children's play area​ ​: If the sharpness doesn’t last for a month, something will happen.

There is a case of blood and tears: the training institution installed a large screen on the back wall of the classroom. As a result, the students in the first row were only 1.2 meters away from the screen. In two months, parents complained that their children's myopia was getting worse. Remember the classroom screen​ ​Nearest viewing distance = screen height × 1.5​ ​This formula saves lives.

Maintenance costs are hidden in the details

Ask these three questions when choosing a site, and you can save tens of thousands of dollars later:

1. "Do you need to dismantle the suspended ceiling for disassembly and cleaning? "(Save 30% on labor costs by maintaining the structure before selection)
2. "In which direction does the cooling air duct blow? "(Avoid areas where people move around to reduce noise)
3. "Where is the storage location for spare modules? "(Storing spare parts on site can shorten maintenance time by 80%)

I saw a smart case last month: a supermarket installed a screen in the fresh food section, and purposely aligned the heat dissipation vents with the air vents of the freezers, which not only cooled down the temperature but also saved electricity. The monthly electricity bill was 1,200 yuan less than expected.

​​Editor's opinion​​
If you are worried about site selection now, remember this mantra: "Watch the flow of people, measure the spacing, and calculate maintenance." If you are really not sure, just rent a screen of the same model and try it out for three days. Spending thousands of yuan for testing is better than paying 50,000 yuan for incorrect installation and dismantling. By the way, don’t believe the sales pitch of “it can be installed anywhere” – it is recommended that suppliers who can say this be blocked directly!
