序章
Nowadays, the rear window LED display is quietly changing our driving experience. It can not only display information and make money, but also remind of safety, but it also brings some new problems.
Today, let’s take a deep look at the pros and cons of the rear window LED display to see if it is worth installing on your car.
目次
1. Functions and application scenarios of the rear window LED display
1). Function
1.1). Information display:
It is like a mobile electronic blackboard; you can write whatever you want. For example, if you are in a good mood, you can write “I am in a great mood today”.
If there is a traffic jam, write “Traffic jam ahead, don’t follow me”; it can even display the weather to remind the drivers behind to pay attention to the slippery road on rainy and snowy days.
1.2). Advertising to make money:
This is a mobile billboard that can help you turn your car window into a “money-making machine”. You can rent your car to advertisers and let them advertise on your car window.
It’s like turning the car window into a “walking TV”. Advertisers can change the content of the advertisement at any time and whenever they want.
1.3). Safety reminder:
This feature is very considerate, just like having a “bodyguard” protecting you from behind.
When driving at night, if the car behind you turns on the high beam, it can automatically adjust the brightness so that your car window will not be shaken.
So that you can’t see the road. If you brake suddenly, it will flash immediately to remind the car behind you not to rear-end.
If the car crashes, it can also automatically send a distress signal to tell others where you are.
2). 応用シナリオ
2.1). Private vehicles:
For ordinary car owners, this is not just a decoration, but also a tool to express their personality.
You can use it to show your mood or remind the driver behind you to pay attention to safety.
If you don’t want to drive, you can also rent it out and turn the car window into a “profitable advertising space”.
2.2). Buses:
The rear window LED display installed on the bus is equivalent to an additional “mobile billboard”.
Bus companies can use this screen to display advertisements and increase revenue.
At the same time, it can also be used to remind passengers to pay attention to safety or display some public service information, such as garbage classification propaganda.
2. The relationship between the rear window LED display and driving safety
1). The good side of driving safety
1.1). Convenient communication, less anger:
When driving, sometimes the car behind is too close, or the car in front brakes suddenly, which can easily cause a small conflict.
With the rear window LED display, the driver of the car in front can directly write “Don’t stick so close, thank you” or “Brake, be careful” on the screen.
In this way, the driver of the car behind can understand it at a glance, and everyone feels comfortable and not easily angry, so there are naturally fewer unnecessary accidents.
1.2). Safer driving at night:
When driving at night, the most feared thing is that the car behind turns on the high beam and dazzles your eyes.
The rear window LED display has an advantage. It can automatically sense light. If the car behind turns on the high beam.
It will automatically remind the driver of the car behind, “Don’t turn on the high beam, it’s dazzling.”
In this way, the driver of the car behind can adjust the light in time, and the driver in front can also see the road clearly, which is much safer.
1.3). It can save lives in emergencies:
If the car in front suddenly brakes, the rear window LED display will immediately flash to remind the car behind to brake quickly.
If you accidentally crash, it can also automatically send a distress message to tell others the location of the accident, so that rescuers can arrive quickly and may save lives.
2). Possible troubles
2.1). Blocking vision and unclear vision:
Some rear window LED displays are too large or poorly installed, which will block the driver’s rearview mirror and make the driver unable to see the car behind.
For example, the rear window screens of some taxis are particularly dazzling at night, and the driver can’t see the situation behind at all, which is too dangerous.
2.2). Distraction and easy to get into trouble:
The fancy advertisements and emoticons on the rear window LED display can easily attract the driver’s attention.
If the driver keeps staring at the screen, he will be easily distracted. Once the car in front brakes, he may rear-end it.
In addition, the driver will be distracted when operating the screen in the car, which is a safety hazard.
2.3). Equipment problems are more dangerous:
The rear window LED display is an electronic device after all. If there is a problem, such as a short circuit, it may burn out the circuit in the car or even cause a fire.
If the screen is not installed firmly, it will become loose when driving, and it will fall and hit the car or person behind, which will be a big trouble.
In short, although the rear window LED display is interesting and can facilitate communication and remind of safety, it will also cause trouble if it is not used properly.
So, if you want to install this thing, you must pay attention not to block your sight, don’t be too fancy, and don’t be distracted when operating.
Related departments should also take care of it, and don’t let these screens become safety hazards. In short, driving is still safety first, and everything else is secondary.
3. Design improvements and safety measures for the rear window LED display
1). Design improvement
1.1). Transparent screen design
Imagine that when you are driving, there is a large screen blocking the back and you can’t see anything. How annoying it is!
Therefore, there is now a transparent screen design, just like a thin transparent film on the car window.
When the screen is on, you can see the information, and when it is not on, it is just like an ordinary car window, without any delay.
This transparent screen can also let light pass through, and can be used during the day and at night, which is convenient and safe.
1.2). Intelligent 輝度 adjustment
When driving, the light changes a lot; sometimes the sun is dazzling, and sometimes it is pitch black.
If the screen brightness remains unchanged, it is either unclear or dazzling. Therefore, now there is an intelligent brightness adjustment function.
The screen can “sense” the surrounding light and automatically adjust the brightness.
For example, during the day, when the sun is strong, the screen will be brighter; at night, when the light is dim, the screen will be darker.
So that the driver will look more comfortable and will not be distracted by the screen being too bright.
1.3). Display content optimization
In the past, the screen displayed content was either too simple or too complex, and the driver had to adjust it by themselves.
Now it is different. The screen can be set in a variety of display modes, such as text that can move left and right.
Scroll up and down, and flash, so that it can attract the driver’s attention without distracting them.
Moreover, the screen can also set up a list of programs in advance, such as “I’m in a good mood today” and “Be careful”, and play them automatically in order.
So the driver does not have to operate the screen all the time, which is much safer.
1.4). Optimization of installation position
The installation position is also critical. Some screens are installed too high or too low, and the driver has to twist their neck when watching, which is very inconvenient.
Now, designers will install the screen in the most suitable position according to the size and shape of the car window.
For example, the lower part or side of the car window, which will not affect the driver’s view of the road conditions behind, and can easily see the information on the screen.
In addition, protective covers and guardrails will be added around the screen to prevent the screen from being damaged or scratched.
2). Safety measures
2.1). Physical protection
When the car is running outside, it is inevitable to encounter some accidents, such as being hit by stones or scratched by other cars.
Therefore, a protective cover will be installed on the outside of the screen. This kind of protective cover is made of particularly strong materials, such as tempered glass or polycarbonate board, which is highly transparent and impact-resistant.
There will also be guardrails around the screen, just like putting a layer of “armor” on the screen to protect it from damage.
2.2). Electrical protection
Although the screen is a small gadget, it is also an electronic device. If there is a problem with the circuit, it may cause greater trouble.
Therefore, the power supply of the screen has many layers of protection, such as overcurrent protection, short circuit protection, overheating protection, and overvoltage protection.
This is like adding a layer of “safety net” to the screen. Once there is a problem with the circuit, these protection measures will be activated immediately to prevent the screen from being damaged or causing a fire.
In addition, the entire screen will be grounded for lightning protection, so there is no need to worry about the screen being damaged by lightning in thunderstorms.
2.3). Monitoring and alarm
Some criminals may have evil intentions on the screen, such as deliberately destroying or stealing it.
Therefore, surveillance cameras are now installed around the screen to monitor the screen in real time.
Once someone is found to be destroying the screen, the camera will transmit the picture back to the monitoring center and trigger an alarm at the same time.
The alarm will scare away the bad guys, and the staff of the monitoring center will immediately receive the alarm information and take timely measures.
2.4). Information security
Nowadays, the Internet is so developed, and the screen is also connected to the Internet. If it is attacked by hackers or infected by viruses, it will be troublesome.
Therefore, the control computer of the screen will install antivirus software and a firewall, just like adding a “firewall” to the screen to prevent the invasion of network viruses.
Moreover, the screen can also register and authenticate the device, and only the authenticated device can connect and control the screen.
All data transmission will be encrypted, so that even if the data is intercepted, the bad guys can’t understand it, protecting the information security of the screen.
2.5). Emergency handling
When driving, the most feared thing is encountering an emergency. For example, if the car in front suddenly brakes, it is easy to rear-end if the car behind does not react in time.
Now, the rear window LED display will flash immediately when the vehicle brakes urgently, reminding the car behind to brake quickly.
If the car unfortunately collides, the screen can also automatically send a distress message to tell the rescuers the location of the accident.
So that the rescuers can arrive as soon as possible to reduce the loss of the accident.
4. 注目すべき点
It is best to find a professional to install the rear window LED display. They have good craftsmanship and can ensure that the screen is installed firmly and the line is connected firmly without any problems.
The installation position is also critical. Don’t install it too high or too low to affect the driver’s sight.
Generally speaking, it is more appropriate to install it at the bottom or side of the car window, which is convenient to see and does not affect safety.
When using this screen, don’t write too complicated or impolite content, just keep it simple and clear.
In different light environments, adjust the screen brightness, brighter during the day and darker at night, to avoid glare.
It is best to operate the screen when parking. When driving, let the co-pilot help or use voice control, and don’t be distracted.
Regularly check whether the screen is damaged and the line is loose. If the screen is dirty, wipe it with a soft cloth; don’t use highly corrosive detergents.
Find a sheltered place to park on rainy days to prevent water from entering the screen. If you find a problem, deal with it in time, don’t drag it.
