I saw the "moving" advertising screen in the mall last month, right? It's the effect of the picture that looks like it's about to drill out of the screen. My cousin was crazy at that time and insisted on installing one at the door of his own hot pot restaurant. As a result, he searched the Internet - good guy! There are prices ranging from 20,000 to 200,000 yuan. Is this water too deep? Today we will talk about the purchasing tips of 3D scrolling screens, so you will not be a sucker after watching them.

First understand what the real 3D scrolling effect is

Don’t be fooled by the merchants! Some so-called 3D screens are actually ordinary LEDs with animation materials. Real guys have to meet three hard indicators: ① ​​Refresh rate is not lower than 1920Hz​​(Otherwise the dynamic screen will be distorted)② ​​Horizontal viewing angle ≥160 degrees​(You can also see the entire site on the side)③​with automatic brightness compensation function​​(Don’t catch blind under the sun). A while ago, a milk tea shop owner was greedy for cheapness. The screen he bought was like a mosaic at noon. Do you think it was upset?

Procurement channels have hidden secrets

There are three main ways to buy this thing now: 1. E-commerce platform (the deepest water is, and it is easy to buy second-hand renovations) 2. Offline physical stores (can see the physical items but have a high premium) 3. Look for manufacturers directly (the most reliable but you have to be able to choose). When I was equipped with equipment for wedding companies last year, I saw someone selling engineering finishes as new products. The machine within 200 hours of booting up was hailed as "brand new and unused". So,​Be sure to check the factory inspection report and boot time record​, it’s the same as looking at the odometer when buying a car.

Devil details are hidden in the parameter table

I've learned so much here! Focus on these five parameters:

• ​Pixel spacing​: Use P3 or less indoors, and at least P6 outdoors (the smaller the number, the clearer it is)
• ​​Protection level​: IP65 certification must be provided outdoors (dust-proof and waterproof)
• ​​Grayscale​: Starting at 16bit (color transition is natural)
• ​Power supply method​: The redundant configuration of dual power supplies is the most secure (no black screen is left off)
• ​​Warranty Terms​: The five-year insurance for replacement of lamp beads is the true conscience

For example, a 270-degree curved screen installed in a shopping mall in Singapore has not changed a single lamp bead in three years because it uses self-healing lamp bead technology. Guess what? When purchasing, they specifically asked the manufacturer to provide it.72 hours continuous aging test video​, is this trick amazing?

Installation and debugging are the highlights

Don't think it's all done if you buy it! Last month, I helped my friend inspect the equipment and found three fatal problems: 1. The steel structure load-bearing is 20% less (almost an accident) 2. The cooling fan is installed in the reverse (causing local overheating) 3. The signal source is not subject to anti-interference treatment (snowflakes flash from time to time). Here is the key point:​The installation team must have a special operation certificate​, these projects should be tested during debugging:

1. Temperature changes of 4K videos for 8 hours continuous playback
2. Automatically adjust the response speed under ambient light at different times
3. Data recovery capability after emergency power outage

After-sales guarantee, don't listen to verbal promises

The most tricky thing I have ever seen is a customer who had broken the control card after using the screen for half a year. The manufacturer actually said that "the accessories have been discontinued." Therefore, the black and white words should be written: ① ​​10 years of supply of core accessories​​ ② ​24-hour remote technical support​ ③ ​​Fault response should not exceed 4 hours​. Reliable manufacturers will have their own cloud monitoring system, which can detect problems such as voltage abnormalities and color temperature deviations in advance, just like our automobile OBD system.

Speaking of this, I remember a real thing - the circular screen of a Korean e-sports hall has experienced typhoons, heavy rainstorms, circuit surges, and even hit by a support stick during the three years of operation. I have been relying on the manufacturer's preventive maintenance services until now. The contract is written in black and white​Domestic physical examination service twice a year​​, this money is worth spending!

I want to tell you, buying such professional equipment is like finding a partner, you can’t just look at the appearance or not. You have to find out the details, verify your integrity, and see if you can live. Next time you want to purchase, you might as well rent it for a few months first, after all, you will see the most effective results with your own eyes. By the way, don’t trust those merchants with vague quotations. All serious manufacturers dare to spread out the configuration list and inspection report for you. This is the master of real gold and not afraid of fire.
