I heard that Dayao wants to install a two-color LED screen? Don't rush to place an order, check out these points first!

Alas, many fellow villagers recently asked me: "We Yaoyao want to install a two-color LED display. Where should we buy it?" To be honest, this is like buying a mobile phone. It looks like buying a mobile phone. It may be a thousand miles away from using something that looks similar. Let’s talk about this today, so you can be clear after reading it!

1. First understand: What kind of screen do you need?

​​Core question: How to choose a dual-color screen or a full-color screen?​​
This matter has to be clearly stated. Two-color screens (usually red and green double base colors) are most suitable for displaying text + simple patterns, such as:

• Government unit notification board
• Registration guidelines for township health centers
• School playground score card

If you want to play video ads or something, you have to use the full color screen. But then again, the two-color screen has it​Money-saving tricks——The power consumption is only 1/3 of that of a full-color screen, and the maintenance cost is much lower. Last year, the screen installed in the cultural square in our county chose the two-color model, which saved 20,000 yuan a year of photoelectric bill!

2. Guide to avoid pitfalls: Three must-see hard indicators

​​1. Depend on whether the manufacturer's foundation is strong?​

• Is there any​ISO9001 certification​(It’s just like having a production license for food)
• The production workshop is large enough (it is recommended to pass directly if it is a small workshop below 5,000 square meters)
• The monthly production capacity starts at least 10,000 square meters, so delivery will not be delayed

​2. Don’t be fooled with technical parameters​

• ​​Refresh rate ≥1920Hz​​(The higher the number, the less eye-catching the picture)
• The brightness can be automatically adjusted (it is not dazzling if you can see clearly during the day and night)
• Protection level is at least IP54 (no problem to protect yourself from rain and dust)

​3. After-sales service is the focus​

• Must have24-hour technical hotline​(You can find someone if you have problems in the middle of the night)
• The installation team must be professional (it is best to bring a master with more than ten years of experience)
• The warranty period starts at least 3 years (it means you have confidence in quality if you dare to protect it for so long)

3. The secret of the price is heavy: bargaining like this will not be slaughtered

​​Common quotation routines​​：

• Price of nude screen does not include installation
• Sell ​​second-hand refurbished pieces as new
• Virtual pixel density

​Expert bargaining tips​：

1. Requested3 years of maintenance record​(Look at the revision rate)
2. Compare the same modelExport version parameters​(The quality requirements for export goods are higher)
3. Focus on checking power modules (many manufacturers cut corners in this area)

Let me give you a real case: Last year, there was a unit in the county next to us who bought a batch of copycat screens for cheap purposes. As a result, after using them for half a year, it started to "inflict epilepsy" - it was light and not light. Later, I changed to a serious manufacturer. Although it cost 20,000 yuan more, I installed it.Intelligent temperature control system​, the high temperature at 40 degrees Celsius is still running stably in the summer.

4. Personal opinion: These details are the easiest to fall

After working on the project for so many years, I found that the three most likely things to be overlooked by everyone:

1. ​​The power supply line must be taken separately​​(Don’t squeeze a switch with the air conditioner, it’s easy to trip)
2. ​​The foundation must be hardened in advance​ (Especially outdoor screens, otherwise it will easily become erratic in the rainy season)
3. ​​Operational training is indispensable​(Many units buy high-end screens but only turn on and off)

Take our local internet celebrity night market as an example. When I installed the screen, I didn’t pay attention to dust protection, but the screen was gray in just three months. Later the manufacturer installed it​Self-cleaning filter​, it’s still as bright as the new one after more than two years. So, buying a screen is not a one-time deal, it depends on the long term.

Finally, let’s say the heartfelt words: buying an LED screen is like finding a partner. You can’t just look at your appearance (appearance), but also look at your financial situation (manufacturer’s strength), temper (stability), and whether you can live a life (after-sales service). Remember,​That is certainly something that can be exported to Japan and South Korea​——The customers over there are poisonous eyes, and the products cannot enter other people's market without a few brushes!
