Introduction
With the continuous development of technology, installing LED displays on private cars has become an emerging trend.
LED displays can not only provide car owners with personalized display space but also play a variety of functions, such as publicity and reminders on specific occasions. However, is there anything worth noting when installing LED displays on private cars?
Note 1: Compliance with laws and regulations for installing LED displays
Although specific regulations vary from country to country, many countries have similar laws and regulations to regulate the installation of private car body advertisements, logos, and LED displays. Some common legal and regulatory points include:
- Restrictions on advertising content:
Advertising content must be legal, true, and accurate and must not contain false, misleading, or illegal information. Some countries may also require that advertising content be approved by relevant departments.
- Advertising location and size:
The location and size of advertisements are usually strictly restricted to ensure that they do not block the driver’s view or interfere with the safety of other road users.
For example, key driving vision areas such as the front windshield, side windows, and rearview mirrors may prohibit the installation of any advertisements or logos.
- Safety performance requirements:
The installation of LED displays must ensure that they do not have a negative impact on the safety performance of the vehicle.
This includes ensuring that the display screen is firmly fixed and will not fall off or cause danger during driving.
- Lighting and brightness restrictions:
The brightness of the display screen must comply with local traffic management regulations and must not cause glare at night or in low-light environments, affecting the sight of other road users.
Note 2: LED display screen selection and installation location
1). LED display screen type selection
When choosing an LED display screen suitable for private car installation, you need to consider a variety of factors, including the flexibility, thickness, weight, and durability of the display screen. The following are several types of LED display screens suitable for private car installation:
1.1). Flexible LED screen:
Flexible LED display screens have extremely high flexibility and can fit various curved surfaces, making them suitable for installation in irregular parts of the vehicle.
Lightweight, has a small impact on the vehicle load, and is easy to install and remove.
1.2). Ultra-thin LED screen:
The ultra-thin LED display screen has a very small thickness and will hardly increase the total volume of the vehicle after installation.
It has good visual effects and a clear display, suitable for car owners who pursue beauty and practicality.
When choosing, you also need to consider the resolution, brightness, refresh rate, and other parameters of the display screen to ensure that the display effect meets your needs.
At the same time, products with reliable quality and well-known brands should be selected to ensure service life and safety.
2). Installation location considerations
The installation locations of private car LED display screens are mainly rear windows, roofs, etc., and each location has its advantages and disadvantages:
2.1). Rear window installation:
Advantages: Easy installation, no change in the appearance of the vehicle, and little impact on the driving line of sight.
Disadvantages: It may block the rear window line of sight and affect the use of the rearview mirror. It is necessary to ensure that the content of the display screen is not too complicated or flickering to avoid interfering with other drivers.
2.2). Roof installation:
Advantages: Wide field of vision, the display screen is easy to be seen by other vehicles, and is suitable for advertising or publicity.
Disadvantages: Increased wind resistance, which may affect the stability of the vehicle. It is necessary to ensure that the installation is firm to prevent it from falling off during high-speed driving.
When choosing the installation location, factors such as line of sight blocking, wind resistance, aesthetics, and safety should be considered comprehensively.
At the same time, it is also necessary to comply with local laws and regulations to ensure that the installation location is legal and compliant.
3). Installation methods and techniques
When installing the LED display screen, the following steps and precautions should be followed:
3.1). Installation steps:
Determine the installation location and ensure that the location is legal and compliant and does not affect the driving vision and safety.
Clean the installation surface, remove dust and oil, and ensure that the display screen is firmly pasted.
Choose a suitable fixing method according to the type of display screen and the installation location, such as using glue, screws, or special brackets.
Connect the power cord and control line to ensure that the display screen works normally.
Test the display screen effect, adjust the brightness and content, and ensure that the display effect is satisfactory.
3.2). Fixing method:
For flexible screens, special glue or double-sided tape can be used for pasting to ensure that the pasting is flat and firm.
For ultra-thin screens, screws or special brackets can be used for fixing to ensure that the installation is stable and reliable.
3.3). Precautions:
During the installation process, damage to the surface and internal structure of the display screen should be avoided.
Ensure that the power cord and control line are connected correctly and firmly to avoid short circuits or poor contact.
After the installation is completed, a comprehensive inspection should be carried out to ensure that the display screen works properly and is firmly installed.
Note 3: Power supply and line safety for installing LED display screens
1). Power supply selection:
When installing private car LED display screens, the power supply is a big question. If you choose the right one, the display screen will work steadily; if you choose the wrong one, there may be some electrical hazards, or at least you have to feel sorry for the repair costs.
1.1). Cigarette lighter power supply:
Cigarette lighters are available in our cars. You can power the display screen by plugging in an adapter, which is very convenient.
However, you have to choose an adapter with overload protection. Otherwise, if the display screen has a little more power or there is a problem with the line, the current will soar, and it may burn the circuit on your vehicle.
You also have to pay attention to the power limit of the cigarette lighter so as not to let your display screen become an “electric tiger” and drag down the cigarette lighter.
1.2). Battery power supply:
Battery, that is, the “big battery” in the car, has sufficient power and a stable power supply.
However, you have to be careful when connecting directly to the battery, and you have to have some professional knowledge. Otherwise, if the wrong wires are connected or the fuse is not installed properly, a short circuit or fire may occur.
A fuse or circuit breaker must be installed, just like a “fuse” is installed in the circuit. If something goes wrong, it can cut off the power supply in time to protect your car.
When choosing a power supply, don’t forget safety first. Choose a reliable quality and standard one. Also, it is best to read the vehicle manual to see what recommendations or restrictions the manufacturer has on the power supply.
2). Line layout:
Line layout sounds simple, but there are actually many tricks.
2.1). Avoid interference:
Did you know? Lines will also “fight” with each other, especially if they are too close to the original electronic system lines of the vehicle, which may generate electromagnetic interference and affect the normal operation of the vehicle.
So, the lines should be kept as far away from sensitive electronic systems as possible, such as engine control units, airbag systems, etc. If you really can’t avoid it, use shielded wires or twisted wires to reduce electromagnetic radiation and interference.
2.2). Firmly fixed:
The line cannot be thrown in the car casually, and it must be firmly fixed to the vehicle structure with a cable tie or a wire clip. Otherwise, when the car starts, the line will swing around, be rubbed, or be short-circuited, which will be troublesome.
When the line passes through a metal hole or gap, you must also be careful and seal it with a rubber sleeve or sealant to prevent the metal edge from cutting the line.
2.3). Easy to check:
The line layout should be simple and clear, but don’t make it look like a maze. Otherwise, when you want to check or repair it in the future, you will have to find the line for a long time.
It is best to mark the direction and purpose of the line at the key connection point so that when a problem occurs, it can be quickly located and solved without tossing around.
3). Waterproof and dustproof treatment:
Private cars will inevitably encounter windy and rainy weather or when the road conditions are bad. Therefore, waterproof and dustproof treatment must be done well.
3.1). Waterproofing of LED display:
When choosing a display, you have to choose one with good waterproof performance, and the waterproof level must meet the requirements of the vehicle’s use environment. Don’t let it rain a little, and the display will “go on strike.”
The joints between the display and the vehicle structure must also be sealed with waterproof glue or sealing strips to prevent moisture from seeping in. Otherwise, once water gets in, the display may be “scrapped.”
3.2). Circuit waterproofing:
The connection of the line is a “weak link”, and it must be sealed with waterproof joints or waterproof tape to ensure that moisture cannot enter. Otherwise, if water seeps in and the line short-circuits, it will be dangerous.
When the line passes through the external structure of the vehicle, it must also be protected with a waterproof sleeve or waterproof box so that rainwater cannot enter.
3.2). Dustproof treatment:
Sometimes, dust or something will get into the car. Therefore, the display and line must be cleaned regularly to prevent dust accumulation from affecting heat dissipation and performance.
You can also spray some dust-proof agent or install a dust-proof net on the display screen and the surface of the line so that dust will not easily adhere to it.
Finally, you need to pay attention to the installation of the power supply or other lines of the LED display screen on the vehicle. Because it is related to electricity, there is still a certain risk. It is best to ask a professional installer to operate.
Note 4: Content and display control of LED display screen
1). Content specification:
Installing LED display screens on private cars is a good thing to attract attention. However, the display content must be in accordance with the rules, and it must not be careless or violate the law and regulations.
1.1). Legal and compliant:
First of all, the content on the LED display screen must be legal and not use bad information such as pornography, gambling, drugs, violence, terrorism, and rumors. These are illegal.
Also, don’t infringe on other people’s privacy, reputation, etc. For example, don’t casually put other people’s photos, names, or sensitive information on the display screen.
1.2). Civility and friendliness:
The content on the display screen must be civilized and friendly and not use vulgar, insulting, or provocative language. We have to be car owners of high quality and not add to the trouble of society.
It is best to display some positive content, such as public service advertisements, positive energy slogans, etc. This will not only attract attention but also convey positive energy, making society more harmonious and beautiful.
1.3). Comply with traffic rules:
Don’t forget to concentrate on driving when driving, and don’t be distracted by the content on the LED display. Therefore, the content on the display should not be too complicated or too flashing so as not to interfere with the sight of other drivers.
In short, the content on the display must be legal, civilized, and friendly, and traffic rules must be obeyed. Only in this way can the display become a window for conveying positive energy rather than a source of trouble.
2). Brightness and color adjustment:
The brightness and color of the LED display are a big deal. If it is adjusted well, the viewing effect is great; if it is not adjusted well, it may not be clear.
2.1). Adjust the brightness according to the ambient light:
When the light is strong during the day, the brightness of the display should be adjusted higher so that the content can be seen clearly. At night or on cloudy days, you have to lower the brightness to avoid dazzling other people’s eyes.
Some advanced display screens also have an automatic brightness adjustment function, which can automatically adjust the brightness according to the ambient light. This is convenient, and you don’t have to adjust it manually.
2.2). Color adjustment:
The color must also be adjusted well. If the color is too bright, it may be dazzling, and if it is too light, it will be unclear. So, you have to adjust the color according to the content to make the content more vivid and easy to read.
You can also adjust the color according to different occasions or festivals. For example, during the Chinese New Year, you can adjust it to red, which is more festive; during ordinary times, you can adjust it to blue or green, which is more refreshing.
In short, you have to work hard to adjust the brightness and color of the display screen. You have to adjust it according to the ambient light and content so that the display screen will “sparkle” in different environments and attract more people’s attention. At the same time, you have to be careful not to dazzle other people’s eyes and be a quality car owner.
Note 5: Driving safety and maintenance of vehicles after installing LED display screens
1). Driving safety impact:
Although installing LED display screens on private cars can bring a lot of fun and practicality, it may also have a certain impact on driving safety. Therefore, we must take these potential safety issues seriously.
1.1). Driving sight impact:
The location and size of the LED display screen need to be carefully selected to ensure that it does not block the driver’s sight. In particular, for displays installed on the front windshield or side windows, it must be ensured that its content does not attract the driver’s attention too much, causing distracted driving.
The brightness and color of the display screen also need to be properly adjusted to avoid glare at night or in low-light environments, affecting the driver’s sight and judgment.
1.2). Vehicle stability impact:
Installing a display screen may increase the wind resistance of the vehicle, especially when driving at high speeds. Therefore, the design and installation of the display screen need to minimize the impact on the aerodynamic performance of the vehicle to ensure its stability.
In addition, the weight and installation position of the display screen also need to be considered to avoid adverse effects on the vehicle’s suspension system and driving stability.
In order to ensure driving safety, we must strictly abide by relevant regulations and standards when installing LED display screens to ensure that the position, size, brightness, and color of the display screen will not have a negative impact on driving vision and vehicle stability.
2). Fault handling:
Although we have done sufficient maintenance, some common faults may still occur in LED display screens, such as black screen, flower screen, etc. These faults not only affect the display effect but may also have a certain impact on driving safety.
2.1). Black screen fault:
In case of a black screen fault, first, check whether the power connection is normal and whether the fuse is blown.
If the power connection is normal, it may be a circuit fault in the internal display screen or damage to the control module. At this time, you should contact professional maintenance personnel for inspection and replacement.
2.2). Flower screen fault:
The flower screen fault may be caused by a short circuit in the internal circuit of the display screen, unstable signal transmission, or a control module failure.
In case of a flower screen fault, you should first check whether the connection line is loose or damaged and whether the signal transmission is stable. If the problem persists, you should contact professional maintenance personnel for inspection and replacement.
When handling faults, we should ensure safety first and avoid inspection or replacement operations during driving. In case of emergency, the vehicle should be parked in a safe place on time, and professional maintenance personnel should be contacted for processing.
In short, after installing the LED display, we need to pay close attention to its impact on driving safety, perform regular maintenance, and deal with common faults in a timely manner. This can ensure that the LED display always maintains good display effects and stability, providing strong protection for our driving safety.
