Recently, a friend who runs a gym asked me: "Brother, I want to install a three-color LED screen in the store. Where do you think you should buy this thing? "This made me stunned--there are more display screens on the market than treadmills in gyms, but it is really hard to find those that are truly reliable. Today we will talk about this matter, keep your heart like a mirror after reading it.

First understand what a serious three-color screen is

To put it bluntly, the three-color LED is a display screen composed of three basic colors: red, green and blue. Although there are many vocals in advertising, there are actually three levels on the market:

• ​​Bronze grade​​: Only fixed text and simple patterns can be displayed, and the type of scrolling subtitles in the street shop
• ​​Golden grade​​: Can broadcast dynamic pictures and preset animations, commonly used in gym class schedule screens
• ​​King level​​: Support live video and real-time video, like a large screen like a concert

The key point is here! ​ ​A truly professional three-color screen must have intelligent color tuning function​​, can automatically adjust the brightness according to ambient light. For example, the gym project we did for Southeast Asia, the screen brightness can soar to 7500cd/m² when the outdoor light is strong during the day, and automatically drop to 800cd/m² at night without any dazzlingness.

How to choose the most secure purchasing channel

There are three main ways now:

1. ​​Direct purchase by manufacturer​​(For example, we have our own factories)
   The advantage is that it can customize special sizes. Last week, I made a special screen with an arc angle of 87° for the boxing gym in Tokyo. The key is guaranteed after-sales service - the display is bought for 30% and 70% packed, and later maintenance is too important.

2. ​​System Integrator​​
   Suitable for those who need an overall solution, such as the gym that needs to connect the audio system and the display screen at the same time. But you have to be careful about the difference between middlemen and middlemen. Last year, a customer bought screens through middlemen, and the price was 40% more expensive than looking for factories directly.

3. ​​E-commerce platform​​
   It is only recommended to buy a small display screen. Do not buy online if it exceeds 3 square meters! There are many things that have broken modules and water flowed into the joints during transportation.

Guide to avoid pits (lectures of blood and tears)

I discovered it recently when I helped my customer to inspect it​​Three common diseases​​：

1. ​​Brightness virtual mark​​: The nominal 5000cd/m² is actually measured only 3800, and it is impossible to see clearly under the sun.
2. ​​Color difference trap​​: The red shows orange color, and the green turns yellow. This is mostly made of inferior lamp beads.
3. ​​Waterproof false​​: It is said to be IP65 protection, but it will be short-circuited as soon as it rains. This kind of screen can't last for three months

I'll teach you some testing methods:​​Use a flashlight to shine the seam​​, if you can see the light transmission, the sealing is not done well. The fence screen we made for the stadium is fine if we use a high-pressure water gun to rush on heavy rains. The key is that the joints of the module are sealed with double silicone.

How much water is the price

There are quotations for three-color screens on the market from 800 to 3,000 yuan per square meter, and the main differences are in these places:

• ​​Lamp bead brand​​: Imported lamp beads are 15% more expensive than domestic ones, but their lifespan can be 30,000 hours more
• ​​Power supply configuration​​: The total negative drive saves 30% power than traditional power supply, making it more cost-effective to use it for a long time
• ​​Control system​​: 8% more expensive with intelligent dimming system, but can save 30% of electricity bills

To give a real case: A fitness chain in Seoul changed 18 screens last year and chose a model with automatic brightness adjustment, saving more than 70,000 yuan a year of electricity bill. So,​ ​You can’t just look at the unit price when buying a screen, but you have to calculate the comprehensive cost of three years.​​。

My heartfelt advice

Buying a three-color LED screen is the same as buying a fitness card - don’t just look at how new the equipment is, it depends on whether the coach is professional or not. When looking for a manufacturer, you must look at these three points:

1. ​​Is there any own laboratory​​(The photoelectric laboratory in our factory has 2,000 square meters)
2. ​​Do you dare to sign a warranty contract​​(We dare to promise to replace it with free of charge within three years without human damage)
3. ​​Have you done similar projects?​​(The screen requirements for gym and shopping mall screens are completely different)

Finally, I would like to remind novices: Don’t rush to sign and accept the goods! Must take it​ ​Colorimeter gamut coverage​​, the professional three-color screen must cover at least 72% of NTSC. Every screen we send to Japanese customers has a test report, which is what a serious manufacturer does.
