Hey, have you noticed? Nowadays, those shopping mall windows on the street are becoming more and more playful! It clearly looks like a piece of ordinary glass, but when you get closer, a moving advertisement suddenly pops up. This thing is a transparent LED display. Recently, many merchants in Meitan asked me: Where can I buy this kind of "invisible display screen"? Today we are going to talk a little more down to earth and teach beginners step by step how to find a reliable transparent screen.

What is the magical operation of transparent LED screen?

In human terms, it is just a piece of glass when not in use, and can display a picture when powered on. Here comes the point,​ ​transmittance​ ​Directly determines the quality of the effect. The light transmittance of ordinary glass is about 92%, and the good transparent screens on the market can achieve about 86%, which is equivalent to more than 1,400 micro lamp beads arranged on steel wires per square meter. There was a milk tea shop in Meitan that installed this last year. It had floor-to-ceiling windows during the day and a dynamic menu at night. Customer traffic increased by 40%.

Where in Meitan can this thing be used?

• ​​commercial complex​ ​: I passed by the pedestrian street in the old town two days ago and saw a jewelry store using transparent screens as its display windows. The diamond necklace rotated 360 degrees on the "glass". All the aunties passing by took pictures with their mobile phones.
• ​​Cultural Tourism Exhibition Hall​ ​: I heard that a local tea culture center is being renovated. It plans to use transparent screens as display cabinet partitions. Visitors can see the ancient tea trees behind them through the screen, and the brewing tutorial will be displayed at the same time.
• ​​Government Affairs Hall​ ​: In the newly built service hall in Jiangnan New District, the information desk is equipped with a half-person-high transparent screen, which can display the call information without blocking the staff.

Five parameters you must study when looking for a transparent screen

1. ​​Don’t trust false standards for light transmittance​ ​: Hold a piece of A4 paper against the screen. The minimum requirement for clearly seeing the text on the paper is 80% light transmittance.
2. ​​The brightness will change on its own​ ​: The indoor screen is 800 nits during the day and automatically drops to 300 nits at night so that it is not dazzling (don’t underestimate this function, it can save 30% on electricity bills)
3. ​​The seam cannot exceed 1mm​ ​: Last year, a hot pot restaurant installed a screen with too large seams, which looked like a mosaic from a distance.
4. ​​Protection grade at least IP43​ ​: Meitan has high humidity, and moisture inside the screen will cause a short circuit.
5. ​​The control system must have a memory function​ ​: It is very important to be able to automatically resume playback after a sudden power outage and restart.

Real people and real stories will teach you how to avoid pitfalls

My cousin renovated the KTV last year and found a small workshop for cheap. As a result, "alopecia areata" appeared after three months of installation of the transparent screen - the lamp beads in some areas did not light up and looked like moss had grown on them. Later inspection found that the packaging process was not up to standard and the steel wire bracket was rusted, resulting in poor contact. The shipping fee to return to the factory for repair was more expensive than the screen, so in the end I had to smash it and reinstall it. A lesson learned through blood and tears, friends!

Where to find reliable suppliers

There is actually no local manufacturer in Meitan (the technical threshold for this thing is high), but you can start from these channels:

1. ​​Brand service outlets​ ​: Some large manufacturers have offices in Guiyang, providing one-stop service from project design to installation and commissioning.
2. ​​Cooperation with project contractors​ ​: Find integrators who have done bank branch or airport projects. They have a stable supply of goods.
3. ​​Government centralized procurement directory​ ​: Brands purchased for government affairs projects, the quality of which has been reviewed at least three times

There is a little trivia:​ ​Never buy directly online​ ​! For transparent screens, the window structure needs to be measured on-site, and nine out of ten common sizes online will not match. Last time, a beauty salon purchased and installed it online, but it turned out that the load-bearing frame and the glass curtain wall did not match, and the entire screen tilted outward by 15 degrees, scaring customers away from walking underneath.

Maintenance knowledge

Don’t think that everything will be fine once you install it, this thing is very delicate:

• Wipe the steel wire bracket with absolute alcohol every month to prevent dust accumulation from affecting light transmission.
• During the rainy season, turn on the phone for at least 2 hours a day to use screen heat to drive away moisture.
• System software must be upgraded quarterly, otherwise screen freezes may occur

Heartfelt advice

The transparent LED screen looks cool but is actually quite deep. Beginners remember three iron rules:

1. ​​Don't be cheap​ ​: There is definitely a problem if the unit price is less than 12,000/square meter
2. ​​A warranty agreement must be signed​ ​: Core components are guaranteed for at least three years
3. ​​See cases on site​ ​: Ask the supplier to take you for an on-site inspection, focusing on the display results at 10 a.m. and 7 p.m.

Having said that, more and more people are doing this in Meitan. A new car 4S store opened in the suburbs last month. The entire showroom uses a 200-square-meter transparent screen, making the car seem to be floating in the light and shadow. However, according to their manager, it took six drafts of the preliminary plan to solve the heat dissipation problem. Therefore, when looking for a supplier, you must not only look at the product, but also whether it has real implementation experience.
