Car Window LED Display: Why Are They Becoming Popular Now?

It’s common to see LED billboards and signs on the road, in malls, or public places. They’re good advertising tools that can reach people of different races, ages, income levels, status, and interests. However, billboards and signs aren’t the only ways to advertise. Nowadays, it has become common to advertise through vehicles.

With the help of LED displays, it’s easy to advertise using vehicles as long as you have the resources. A good example would be an LED display on a car window. This LED display is fitted specifically at the back of the car window, with the display facing outside. It is a good advertising technique to reach out to specific audiences or customers.

In this article, we’ll talk more about car window LED displays, why they’re popular, their features, and some tips on how to pick the perfect display for your needs.

So Why Are They Popular?

Indeed, a digital display of LED car rear windows is popular. It has a lot of advertising opportunities. If you’re a marketing company, you can use it to generate a lot of advertising revenue. It can also be cost-effective, especially if you have your own car. So, what makes them popular? Let’s go over to each reason below:

Ad Opportunity During Heavy Traffic & Rush Hours

Being stuck in traffic is such a bummer. No one wants to be stuck in traffic. However, traffic is unavoidable, especially if you live in big cities around the world. Even first-world countries aren’t immune to traffic. According to MotorBiscuit, there were around 1.446 billion cars worldwide. If we divide that with the world population, that’s around 20%, give or take.

Hence, with the huge number of car owners, streets will almost always be filled with vehicles. This situation presents an opportunity for ad companies to generate advertising revenue from interested businesses. Advertisers can strategically choose where to deploy cars with LED displays to target specific geographic areas and reach different kinds of customers.

For example, if you’re promoting your business, you can deploy cars with LED to roam around your neighborhood first so that people nearby (e.g., within a five-mile radius) can check out your business. Once your business has been established in your area, you can expand to other areas to expand your reach.

Movable and Not Fixed in a Single Location

Seeing advertisements on moving vehicles can spark curiosity and get attention from people on the streets. Since the vehicle is moving, it can grab attention and make people curious, especially if they aren’t able to finish the ad. And besides that, not being fixed to a single location means that you can cater the ad to different people every day. For example, static billboards will be too repetitive for a motorist who always goes the same route every day.

With car window LED displays for ads, you can add variation to your ad placements and spread it to different audiences. You can even park your car for several minutes and then transfer to another location. 

Affordable and Easy To Use

Compared to traditional static billboards or digital signage, LED displays on cars can be a more cost-effective advertising solution, particularly for businesses with smaller budgets. Billboards placed in strategic areas are costly, and businesses with a budget cannot afford them. Even if there are cheaper billboards, sometimes it’s not worth the expense, especially if it’s not reaching the target customers.

For instance, in the US, billboards cost from $1,000 to $15,000 a month, depending on a multitude of factors. It can even go above $15,000 if the billboard’s location is near business districts or high-foot traffic areas. But with car window digital displays, you don’t have to pay $15,000 or even $5,000. You can buy an LED screen for less than $2,000, and that’s it. You can simply install it in your car and drive around the city.

But if you go to an advertising agency specializing in car window LED displays, you can explore different ad packages per month or per year. However, it’ll surely not go as high as $15,000 for a small business package.

Features of a Car Window LED Display

In choosing a car window display screen, you need to know what specifications and features an LED display should have. Here are some features you’d like to check out:

  1. Durability: LED displays are designed to be durable and long-lasting. In general, LEDs have a longer useful life than LCDs. An LCD screen’s average life is 30,000 hours at the minimum, depending on the brand and quality of the materials used. However, LED screens have a minimum lifespan of 60,000 hours. Assuming you’ll use the car window LED display for eight hours a day, that would be more or less 20 years, whereas an LCD screen at 30,000 hours is only ten years. In a span of 20 years, you can surely get a return on investment that’s 50x or even 100x the initial investment for the screen.
  2. Brightness and clarity: LED displays often come with adjustable brightness levels to ensure optimal visibility both during the day and at night. You’ll mostly like to use max brightness during the day and average brightness at night. This feature helps maintain readability in different lighting conditions. If your screen is not bright enough during the day, people won’t see the content. If your screen is too bright at night, it can be difficult to look at because it’s too bright for the eyes.
  3. Easy Installation and Removal: Car window LED displays are designed to be easy to install and remove, allowing users to attach and detach them from the vehicle’s rear window. Remember that you have to spend extra money on the installation. So be prepared for the cost.
  4. Wireless Connectivity: Options like Bluetooth or WiFi connections are possible with most LED displays today. You can use wireless connections to easily display content on the screen directly from your phone or laptop. Aside from that, you can use screen mirroring to play content straight from your phone. If you don’t want screen mirroring, you can use display adapters that can connect displays wirelessly if connected to the same Wi-Fi network.
  5. Energy Efficiency: LED is popular because it is energy efficient. LED displays consume 50% to 70% less energy than traditional screens. Hence, you don’t have to worry about connecting the LED display to the car’s battery.

Disadvantages of Rear Window LED Display

While the idea of a rear window LED display sounds right, it has certain disadvantages that must not be overlooked. Here are some disadvantages that you should know:

  1. Possible distraction to traffic: LED displays on car rear windows can distract other drivers on the road, which can lead to minor to major road mishaps. Drivers may get distracted when watching content shown on the LED display. It can divert their attention away from the road and prevent them from focusing while driving. Flashing and strobing effects can also cause epileptic seizures in passengers with epilepsy. Hence, be careful with the kind of content you show on the screen to prevent accidents.
  2. Limited viewing time: Unlike billboards or digital signs, the advertisements on car rear window LED displays can be limited, given that the car is moving. If you’re walking in the street and you see a car with an LED display pass by, there’s a big chance that you might not see the whole ad. This limited viewing time may reduce the effectiveness of the advertising compared to other forms of outdoor advertising.
  3. Road limits: Some roads require a faster speed limit, especially on highways. If you’re going fast, some people might have trouble seeing your ad or not seeing it. Aside from speed limits, pedestrians may not be allowed in some areas. Limited pedestrians may cause a limited reach. Advertisers may have limited control over which demographics see their advertisements, potentially resulting in lower conversion rates.
  4. Regulatory limitations: Regulations or restrictions on using LED displays on vehicles may prevent you from installing a rear window LED display. These restrictions may specifically target brightness levels, content, and placement. Advertisers must ensure compliance with local laws and regulations, which can limit the effectiveness of such advertising. We highly advise that you reach out to authorities first before buying an LED screen.

How To Pick a Car Window LED Display

Selecting an LED display involves considering various factors to satisfy your advertising needs and financial capacity. Buying an LED display without a clear purpose is a waste of money. You must first know what you need to prepare before jumping into a decision. To help you with that, here’s our guide on how to pick a car window LED display:

1) Determine Your Purpose

Buying a car window LED display is not a random decision to make. No one simply wakes up and buys an LED display for their car window. However, if there’s a good purpose for it, why not? A common purpose is for advertising. People get stuck in traffic for hours, and you can leverage those to show them ads for your business. Make their downtime during traffic hours meaningful by showing them interesting ads about your business.

If you’re not promoting your business, you can instead use it to promote other businesses. You can sell advertisement time to businesses, charge higher rates during peak traffic hours, create different pricing levels for certain ad lengths, and earn money by simply driving around the city with an LED car display.

2) Set a Budget

LED screens come in different prices, so you need to set a budget before buying. Having a budget can easily help you choose LED models that are within your price range. Generally, we recommend that you set a range for the cost of the LED display that includes the price of the LED display unit, installation fee, shipping fee, ongoing maintenance, and any additional accessories or features.

3) Research About LED Displays

You can’t buy what you need if you don’t know what you’re buying. You should research LED display technology to be familiar with the terms and abbreviations used in the industry. If you immediately go to suppliers and sellers, it can get overwhelming when they start telling you all these specs like nits, hertz, and resolutions. We don’t say that you have to be an expert.

Try to learn the basics and understand the dynamics behind each LED display spec. Being informed about this stuff can help you choose the best product. Moreover, some scrupulous sellers out there would try to sell you something that you don’t need. And if you’re not aware of LED technology, you’ll be easily swayed into buying a more expensive unit when a more affordable unit best suits your needs.

4) Get The Right Measurements for Your Car

Get an LED display that can fit the dimensions of your vehicle’s rear window. It doesn’t need to cover the whole window. Just aim to cover the majority of the window’s area. Cars have different rear window shapes and forms. The best LED screen to pick would be the one that could provide a wider screen size. 

3) Choose the Type of Ad

Would you want to show a video ad or a poster? Is this a text-heavy or graphics-heavy advertisement? We recommend looking for a display to showcase different kinds of content, including text, images, animations, and videos. You may also want to look for displays that can play different file formats without compromising quality and experience.


Car window LED displays are versatile advertising tools because they offer unique selling propositions to businesses interested in more affordable advertising solutions. This advertising method captures different types of audiences and customers on the road. Through the strategic deployment of vehicles in certain places, advertisers can access diverse geographic areas. They can maximize exposure and expand their reach. Moreover, the mobility of these displays ensures that advertisements reach a broader audience, sparking curiosity and garnering attention as vehicles traverse different locations.

In conclusion, LED displays on car windows are just one way of advertising. It may not be a one-size-fits-all solution, but it can drive conversions and revenue for clients. With planning and proper execution, advertisers and businesses alike can use LED displays for marketing and advertising.
