But before purchasing LED outdoor signage for your business, you must ensure you&#;re making a well-informed investment. Your digital signage is likely to last at least 10 years; careful planning will help ensure a successful experience, longer lifetime and lower cost.

Here are eight key factors to consider as you look for the best outdoor LED display screen to meet your needs:

1. Environmental ruggedness

Depending on where your outdoor digital sign is located, you may need to consider how it operates in hot or cold temperatures, as well as in rain, snow, wind, dust and humidity. Against these elements, the design of your screen and its enclosure is critical to the continuous operation and lifespan of the LEDs.

In terms of environmental factors, your first consideration should be removing heat from both the LED elements and their driving electronics. Ask any vendor about their thermal management solution and its ability to maintain LED temperatures within the elemental conditions you anticipate. To protect your signage from the elements, check that the enclosure design meets specifications for resistance to water, dust, humidity, etc. &#; whatever concerns apply to your location.

2. Support every step of the way

Can your potential supplier offer support and advice for the screen&#;s design and permitting process? Will they listen to all stakeholders and design a solution that fits their needs? Can they work with a customer project leader or recommend a qualified installer?

Hopefully, the answer to these questions is yes. You want a partner in this process, not simply a vendor.

3. Maintenance and servicing

Once your LED outdoor signage is installed, routine maintenance and servicing are critical to ensuring it always looks great and lasts as long as possible. Ask your vendor how often calibration is required &#; and how easy it is to accomplish &#; to ensure consistent image quality for years to come.

Similarly, establish how and when the screen will be serviced. Some vendors, such as Samsung, offer a network operations center (NOC) option to constantly monitor your sign and send a technician to fix any issues before you may even be aware of them. To avoid downtime, servicers will need easy access, too, so establish protocols for that.

4. A successful track record

How long has your potential LED supplier been in business? What are other customers&#; experiences? Will the supplier be around in 10 years? Will they be responsive to any needs you may have after installation?

To ensure you get the best outdoor LED display possible, ask for references and referrals from their previous customers, especially for jobs done five or more years ago, to get insight into the provider&#;s integrity.

5. Attention to safety

To local and state governments, your display brightness can be a major safety concern. A sign that&#;s too bright may distract drivers and make it difficult to drive at night. Check if your LED display has an auto-dimming capability to lower the screen&#;s brightness relative to surrounding light, which should minimize it at night, saving power and keeping drivers&#; eyes on the road.

The materials used in the LED screen and its enclosure can also lower the risk of dangerous signage failures and assuage any safety concerns. Look for products certified by Underwriters Laboratory (UL), which imposes strict safety requirements.

6. Price and warranty

You may be tempted to choose the least expensive LED signage option, but you&#;re likely to get what you pay for. Low-cost suppliers use lower-quality materials &#; not military-grade components. Their design teams may not ensure the safety and longevity of your signage. And they may under-specify the screen&#;s performance to lower the cost.

Many signage suppliers offer a warranty, but check the fine print to make sure you understand the exceptions and limitations. Here&#;s where you may be better off going with a trusted brand, even if it costs a bit more.  Ultimately, smartly designed and well-built LED advertising screens will deliver greater overall savings.

7. Choose the best integrator

Your LED supplier may not always be the organization that physically installs the screen. In many cases, you may end up hiring an architect, consultant or project manager to oversee or carry out the installation. Is your LED supplier ready and willing to work with these managers?

You may also simply want to appoint an installer who can manage the entire project. Can your supplier suggest a qualified installer? Again, check their references and ask about the success of previous installations.

8. Visual quality

Outdoor signage is meant to draw the attention of passersby and communicate a message about your brand. The vividness of the image has a significant impact on how that message is received. Your outdoor LED signage should be bright and vibrant, and it should display colors accurately. Skin tones that look washed out, for example, will draw negative attention, so check the LED supplier spec sheet to be sure the display shows true-to-life color.

Another key consideration is pixel pitch, in other words, the space between RGB pixels. It&#;s important you choose a vendor that will match the right pixel pitch for the viewing distance. Over specifying the pitch may cost more, but if the pixel pitch is too large, the visual quality may suffer.

Establishing an outdoor LED signage solution can be a daunting task with many moving parts &#; and concerns about visual quality, cost, safety and reliability. Starting with these eight tips in mind, you&#;ll be prepared to ask the right questions and set your project up for success.

How to choose the right LED screen?

When thinking about how to choose the right LED screen solution, there are a variety of factors to consider and it is essential for you to know certain basics. We also suggest that you do more research on LED screen technology and turn to professionals and reliable resources for more support and information. Below are some basic information and terms for you to consider.

1. Indoor vs Outdoor

An indoor LED display screen is very different from an outdoor LED Display Screen. They have different viewing angles, brightness, power requirements, and durability. Outdoor LED displays are weather-proof, extremely bright, and if properly designed can handle all of nature&#;s elements, including full sun.

2. Type of content displayed on the screen

Determining the type of media and information displayed on your LED screen will allow the manufacturer and supplier to assess the necessary steps between the pixels of the LED screen and its characteristics. When you plan the budget for a LED screen you need to consider the content displayed on the screen or your purchase might prove to be disastrous.

3. Pixel pitch of the LED screen

The choice of the pixel pitch and the LED screen resolution dictates the physical limitations of the screen size, viewing distance, viewing angles, and of course, the budget. The cost of the screen is determined by its resolution and area. In order to produce high-quality videos on a large screen, you need to purchase the screen with the highest resolution possible under your budget. The screen resolution is defined as the total number of vertical and horizontal pixels.

4. Brightness and viewing angles

The unit of measurement of the brightness of the LED screen is nit (cd/m2). The higher the value, the higher the brightness of the screen. The brightness for indoor screens should be no more than 1,500 &#; 2,500 nits. For outdoor screens, the brightness should range from 3,500 nits (for screens without direct exposure to the sun) up to 10,000 nits (when the screen is directly exposed to the sun). Brightness is measured at a normal angle to the screen.

The viewing angle is usually determined by the point where the screen&#;s brightness is 50% of the maximum. You should notice a change in brightness as you walk along the length of the screen. LED screens have a problem unique to this technology, called &#;shoulder obstruction&#;, i.e., when the color change occurs because one LED blocks another LED at critical viewing angles. Viewing angles should include color changes. If a significant color change occurs before the brightness drops to 50%, then that is considered as the viewing angle. The addition of visors between rows of LEDs reduces the illumination of the screen by other light sources, thereby increasing the contrast. This method also reduces the vertical viewing angle, but that is not usually a problem for most LED screen applications.

5. Minimum and maximum viewing distances

Minimum viewing distance can be calculated as pixel pitch x 750-. At this distance, a smooth image is observed. Closer inspection of the video will lead to a &#;decay&#; of the image into separate pixels. For example, for a LED screen with a pixel pitch of 10mm, the minimum viewing distance is 10mm x = 10m.

The formula to calculate the maximum viewing distance is generally Screen Height x 20-30. For example, for a LED screen with a height of 4.56 meters, the distance will be 4.56m x 30 = 137m.
