Dear friends who press the elevator button at least eight times a day when going up and downstairs, have you noticed that the advertising screens in the elevators have suddenly become smarter in the past two years? In the past, I only knew how to broadcast "Infertility and find XX" in a loop, but now I can actually display real-time weather forecasts and interact with my mobile phone to get coupons. What tricks are hidden behind this? Let's take a look today Elevator LED display Those real skills.
1. Don't underestimate this screen, which is more particular than your TV.
Last week, I went to a friend's company and saw their newly installed elevator screen broadcasting 4K ultra-clear promotional videos, and the picture was as smooth as water. This reminds me of the tragedy in an office building three years ago - a low-end screen was installed, and the dynamic screen was played with all the shadows, which made people dizzy and want to vomit. You have to check these three elevator screens Hard indicators：
-
The brightness will change seventy-two times
The elevator car changes more than a dozen times from morning to night, and the screen is as adaptable as a cat's eye. Our products can do it 800-1200 lumens intelligent adjustment , the sunlight shines in at noon and can be seen clearly, and the late night mode is automatically dimmed and not dazzling [^ Company Information].
-
The refresh rate should be fast enough
≥What is the concept of 1920Hz refresh rate? The moment the elevator door opens and closes, the screen switching does not stutter at all. Tested data: When playing fast moving text, the ordinary screen has a drag, and our products can even clearly identify the punctuation marks.
-
Thickness comparable to ultra-thin mobile phones
The space of the car is valuable, and the screen thickness is controlled within 25mm to be considered qualified. The curved screen installed for office buildings in Singapore last year was only 18mm at the thinnest point, which was directly embedded above the elevator control panel [^Company Information].
2. Understand the practical test of the five major scenarios without placing a trap
Recently, I helped three property companies choose elevator screens and found that the most common mistake that novices make is "both both want and want". Remember this golden law: Function follows the mobile line。
✅ Residential elevator Focus on mute
The night mode will be automatically switched after 10 o'clock in the evening, and the brightness will drop below 300 lumens. The owners of the apartment project we were working on in Tokyo reported that this feature allows late-return residents to no longer complain about light pollution.
✅ Office building elevator Must support split screen
The first half of the company is broadcasted and the second half is displayed in real time. A customer originally wanted to install two screens, but later he saved 30% of the cost using our split screen technology.
✅ Hospital elevator Pay attention to antibacteriality
The screen surface should be covered with a nanocoated layer and the alcohol should be rubbed hundreds of times without blurring. This design was praised by the head nurse in a private hospital in South Korea, saying it is much more hygienic than traditional plastic boards [^ Company Information].
✅ Shopping ladder Play with transparent display
After the 86% transparent screen is installed, customers can watch advertisements without blocking the view. Tested data: With a transparent screen, the average stay time of passengers increased by 45 seconds.
✅ Old elevator renovation The key is power supply
DC 24V safe voltage power supply is the bottom line, so it is best to choose a model with UPS backup power supply. Last month, the power outage was cut off due to heavy rains last month, and the elevator screen in a community relied on backup power to broadcast safety tips for 6 hours.
3. The installation location hides great questions. Most people make mistakes
A while ago, I saw a property manager who insisted on installing the screen above the elevator button, but the passenger raised his hand and pressed the floor to block the screen. Three requirements for installation of elevator screens The law of space：
-
Visual Golden Triangle
It is most suitable to install it at the side wall of the car 1.6-1.8 meters away from the ground. This height not only avoids the door-closing sensor, but also conforms to the habit of adults' head-on vision. Our construction team has an exclusive calculation formula that can accurately position it to the centimeter level.
-
Heat dissipation needs to be leveraged
Don't install it directly opposite the vent! The best position is the rear side of the top of the car, which uses the air convection when the elevator is up and down to dissipate heat naturally. Tested data: This installation can reduce the internal temperature of the screen by 12℃ [^Company Information].
-
Line Hiding Technique
The HDMI cable and power cable must be connected to the elevator cable duct. If the exposed cable exceeds 15 cm, it is considered unqualified. There was a project complained by the owner about the exposed cables, and he spent three times the labor fee when reworking.
4. These black technologies are redefining elevator space
Nowadays, elevator screens are no longer just display tools. I'm talking about some of them being implemented. Future Technology：
- Intelligent light-sensitive interaction : The passenger will automatically turn on when approaching, and enter power saving mode after leaving
- Emergency broadcast system : Automatically switch evacuation guidelines during fire, the volume is 100 decibels
- AR navigation layer display : Use your mobile phone to scan the screen to directly display the destination floor roadmap
- Air quality inspection report : Linked car sensor displays PM2.5 values in real time
The project I did for a smart office building last year shocked me the most - their elevator screen could recognize the identity of the courier and automatically pop up the "freight elevator guidance". This is much more advanced than posting A4 paper notifications.
Editor's opinion:
After working in display projects for so many years, my deepest experience is that a good screen should exist like air. It does not overshadow the main point, but it accurately conveys information when needed. Next time you wait for the elevator, you might as well take a look at the screen. Maybe there is black technology that is silently protecting your safety up and downstairs. After all, in this era of interconnected things, even elevators are learning to become more considerate, right?
