Have you been hit hard by LED screens recently? Just like a novice who wants to learn how to increase fans quickly, he is cut off from the leeks when he is not careful when buying a display screen. I just heard a real story last week: a shopping mall spent 800,000 yuan to wear an outdoor large screen. After using it for three months, the "yin and yang face" appeared. The left side lights and the right side is dark like a haunted one. Today, let’s talk about something real and teach you how to prevent lightning like an old bird.

1. Three soul torture questions for buying screens

​​Question 1: Should we be a storefront or a tool to make money?​​

• Shop sign selection​P4-P6 indoor screen​, brightness 800-1200 nits is just right
• Outdoor advertising space must be available​Start 4000 nitsThe waterproof screen is still clear on rainy days
• Stage rental screen is aware​Quick unboxing​, 8 people can play on the basketball court stage in 2 hours

(Knock on the blackboard) The key point is:​Don't believe the "universal screen" nonsense​! Just like you can’t use a beauty camera to take X-rays, special equipment must be used in different scenarios. A bar owner was greedy for cheap and used conference screens to perform. As a result, the singer shook his head and the screen dragged out a rainbow strip, which was laughed at by the guests.

2. The ultimate showdown between online vs offline procurement

(Phone the thigh) Tell me about the inside story of the industry: the price of a popular e-commerce screen is 19,999 yuan, which looks 30% cheaper than the manufacturer. As a result, using second-hand lamp beads + counterfeit power supply, the actual cost is less than 8,000. What’s even more frustrating is that I found that I had to pay an additional 8,000 commissioning fee during the installation - this is the same routine as the live broadcast of the Internet celebrity courses, with the 9,999 private tutoring class followed by the 9,999 private tutoring class.

3. Five-step ultimate skill for factory inspection

1. ​Workshop Raid Inspection​: No direct pass for 10,000㎡ automation workshop
2. ​​Quality inspection report traceability​: ISO9001 is the bottom line, focus on aging test records
3. ​​Case video verification​: Requires real-life pictures of projects of the same type
4. ​​Brightness attenuation test​: Regular manufacturers dare to provide five-year brightness maintenance curve
5. ​Stress test performance​: On-site water splashing test IP65 waterproof authenticity

To give a positive case: The fenced screen at a venue at the Tokyo Olympics last year was conducted in an extreme environmental test six months in advance - from minus 20℃ to baking at 85℃, the screen was not lost without 100 cycles. This kind of perverted test is the real gold that is not afraid of fire.

4. Price fog cracking formula

​​Total cost = screen price + installation fee + three-year electricity fee + maintenance cost​
Don't be fooled by the low-priced screens, make a clear account:

• High-quality screen: 100,000 purchase + 20,000 installation + 30,000 electricity bill = 150,000
• Low-quality screen: 60,000 purchase + 50,000 repair + 60,000 electricity bill = 170,000

(Remembering with cigarettes) What is even more heartbreaking is that some low-end screens consume 40% more power, and the three-year electricity bill difference is enough to buy a new screen. This is the same as choosing level 5 energy efficiency when buying an air conditioner, and buying a cheap air conditioner will hurt.

Editor's opinion

The industry is undergoing a major reshuffle now.​Screen with intelligent management system​Eat the traditional market. Recently I came into contact with a gym case. Their magic mirror screen can display member sports data in real time and can also synchronize live courses - this kind of screen is not a display tool, but a traffic entrance.

What's even more amazing is that the navigation screen of a certain airport can actually automatically push store coupons based on flight delay data. So, you can’t just look at the hardware parameters when buying a screen. You have to ask clearly​​Is there any data interface and extension functions?​. The good screen of the future must be the trinity of "monitor + server + router".

Finally, I would like to say that looking for a supplier is like finding a partner. Just looking at the appearance is not enough. You have to check the education level of the third generation, test the physical examination report, and test your personality and temper. Remember24-hour technical response + five-year warranty​This is the promise of true love, and other sweet words are all hooligans!
