How to Choose an Outdoor LED Display

Jul 26, 2023 | knowledgebase | 3 comments

Purpose and Application of led screen

Before you buy an outdoor LED screen, you need to know what you want to use it for and where you want to install it. Different uses and locations have different requirements for the screen’s features and performance. Here are some questions you should ask yourself to help you choose the right outdoor LED screen for your needs:

  • What is the main function of the screen? Do you want to use it for advertising, information, or entertainment?
  • How far away will the viewers be from the screen? Do you need a high-resolution screen that can show clear images and text even from a close distance, or a low-resolution screen that can cover a large area and be seen from far away?
  • How wide is the viewing angle? Will the viewers see the screen from one direction or from different angles?
  • What are the weather conditions? Will the screen face direct sunlight, rain, wind, or extreme temperatures? Do you need a waterproof, dustproof, and heat-resistant screen that can withstand harsh environments?
  • How much can you afford to spend? What is your budget limit for buying and maintaining the screen?

Pixel Pitch and Resolution

Pixel pitch and resolution are two key factors that affect the quality and clarity of an outdoor LED display. Pixel pitch is the distance between each pixel on the screen, while resolution is the number of pixels that make up the screen. Pixel pitch and resolution are inversely related: the smaller the pixel pitch, the higher the resolution and vice versa.

The best pixel pitch and resolution for an outdoor LED display depend on how far away the viewers will be from the screen and how clear and detailed the image needs to be.

For instance, if you want to show a large image that can be seen from more than 10 meters away, you may choose a pixel pitch of 10mm or more. This will give you a low-resolution screen that can cover a wide area. But if you want to show a small image that can be seen from less than 10 meters away, you may choose a pixel pitch of 5mm or less. This will give you a high-resolution screen that can display sharp and crisp images.

Environmental ruggedness

One of the most important aspects of outdoor digital signage is how well it can withstand different weather conditions and environmental factors. Your outdoor LED screen should be able to operate smoothly and last long in hot or cold temperatures, rain, snow, wind, dust, humidity, and so on. To ensure this, you need to pay attention to the design of your screen and its enclosure, which should protect your LED elements and driving electronics from damage.

The first thing you should look for in an outdoor LED screen is how it manages heat. Heat can affect the performance and lifespan of your LED elements and driving electronics, so you need a good thermal management solution that can keep the LED temperatures within a safe range in any weather. You should ask your vendor about their thermal management solution and how it works in your location.

The second thing you should look for in an outdoor LED screen is how it resists water, dust, humidity, and other environmental factors. Your screen should have a sturdy enclosure that meets the specifications for water resistance, dust resistance, humidity resistance, etc. You should check the enclosure design and make sure it meets the standards for your location.

Take Dubai (Dubai climate)for example, The temperature in the Middle East varies depending on the season and the location, but generally, it is hot and dry throughout the year. The climate in this area of the world is fairly consistent with little variation, and the weather in the Middle East is easy to describe: hot and dry. Summers in Dubai, Abu Dhabi, and other popular tourist cities can reach temperatures of 120°F (49°C) and the blazing sun makes it undesirable to spend much time outdoors.

The challenges of LED display working at high temperature:

  • The open circuit and failure of electronic components

    If the working temperature of the electronic product exceeds the bearing temperature of the chip, its luminous efficiency will be rapidly reduced, resulting in obvious light attenuation and damage. Electronic products are mostly encapsulated with transparent epoxy resin. If the junction temperature exceeds the solid phase transition temperature (usually 125℃), the encapsulation material will be turned into a rubber-like condition and the coefficient of thermal expansion will rise sharply, resulting in the open circuit and failure of the LED Display.

  • The light attenuation of LED display

    The light attenuation reflects the life of the LED display. That is to say, as time goes on, the brightness will be increasingly lower until it dies out. High temperature is the main cause of the light attenuation and the shortening life of LED displays. The light attenuation varies among different brands of LED displays. Usually, LED display manufacturers will give a set of standard light attenuation curves. The luminous flux attenuation of LED displays caused by high temperature is irreversible.

How to Choose the Appropriate outdoor led display

  • Brightness

    The brightness of an LED screen is measured in nits or candelas per square meter. The higher the brightness, the more visible the screen will be in direct sunlight. However, higher brightness also means higher cost and power consumption. Therefore, you should choose a screen with the appropriate brightness level for your needs. For example, if your screen is facing the south or southwest direction, where the sun is strong, you may need a brightness of at least 7000 nits. If your screen is facing the north or northeast direction, where the sun is less intense, you may be able to use a lower brightness of around 6000 nits. If your screen is in a shaded area, such as under tall buildings or trees, you may only need a brightness of 5000 nits.

  • Refresh rate

    The refresh rate of an LED screen is the number of times per second that it updates the image on the display. The higher the refresh rate, the smoother and clearer the motion on the screen. A high refresh rate screen can reduce flickering and ghosting effects, which can cause eye strain and fatigue. You should look for a screen with a high refresh rate, preferably above 2880 Hz if the led screen is going to be taken video by the audience.

  • Contrast ratio

    The contrast ratio of an LED screen is the ratio between the brightest white and the darkest black that it can display. The higher the contrast ratio, the better the image quality and depth perception of the screen. A high contrast ratio screen can show more details and nuances in both bright and dark areas than a low contrast ratio screen. You should look for a screen with a high contrast ratio, preferably above 3000:1. However, you should also check for local dimming performance, as some screens may have a high contrast ratio but poor local dimming control.

  • Color gamut

    The color gamut of an LED screen refers to the range of colors that it can display. The wider the color gamut, the more colors and shades that the screen can reproduce. A wide-color gamut screen can show more realistic and natural colors than a narrow-color gamut screen. You should look for a screen with a wide color gamut, preferably covering at least 85% of the DCI-P3 color space. However, you should also check for color accuracy, as some screens may have a wide color gamut but poor color calibration.

HDR 10 LED DISPLAY

Sep 23, 2022 | knowledgebase | 0 comments

HDR stands for High Dynamic Range, which is a technique of capturing, processing and displaying images that have a much wider range of color and contrast than standard dynamic range (SDR) images. HDR images can show more details in both bright and dark areas, as well as more vivid colors, making them more realistic and closer to what the human eye can perceive. HDR is often used in photography, video games, movies and TV shows to enhance the visual quality and immersion of the content.

SDR VS HDR LED DISPLAY copy

There are several HDR industry standards that define the technical specifications and requirements for HDR content creation and display. Some of the most common ones are:

  • HDR10: This is an open-source HDR standard that is widely supported by most HDR display devices and media platforms. It was announced by the Consumer Technology Association in 2015 and requires a 10-bit color depth, a BT.2020 color space, and a minimum display brightness of 1000 nits.
  • HLG: This is a HDR standard developed by the BBC and NHK for digital program delivery. It was launched in 2015 and does not use metadata, but rather combines HDR signals into TV broadcast signals. It is compatible with current broadcast equipment and has no licensing fees. It is suitable for cable/satellite TV and live broadcast.
  • Dolby Vision: This is a proprietary HDR standard developed by Dolby Laboratories that requires certification and payment. It was launched in 2014 and offers a 12-bit color depth, a BT.2020 color space, and a minimum display brightness of 4000 nits. It also uses dynamic metadata to optimize the HDR image quality for each scene. It is supported by some TV manufacturers such as Sony and LG.

Four requirements for HDR video to be realized, specifically for the HDR10 standard. 

  • 4K resolution, which means they have 3840 x 2160 pixels. This is four times more than the standard HD resolution of 1920 x 1080 pixels. Having more pixels means having more clarity and sharpness in the image, which is essential for HDR.

 

color gumut requirement for hdr led screen
  • High contrast ratio, which means it can show a big difference between the brightest and darkest parts of the image. For HDR10, the display device must be able to produce at least 1000 nits of brightness, which is a measure of how bright a screen can get. It must also be able to show blacks of less than 0.05 nits, which is a measure of how dark a screen can get. Having a high contrast ratio means having more details and depth in the image, which makes it more realistic and vivid. LED displays are very good at achieving high contrast ratios, unlike some other display technologies.
HDR led display brightness and contrast ratio
  • 10-bit color depth, which means they can show 1024 shades of each of the three primary colors (red, green, blue). This is much more than the 8-bit color depth of standard video, which can only show 256 shades of each color. Having more shades of color means having more smoothness and richness in the image, which avoids the problem of “banding” or “stepping” between colors. It also means that some parts of the image can be very bright without affecting the rest of the image, such as the sun, a flash, or a fire.
