An outdoor high resolution LED display is a type of LED display that has a small pixel pitch, which means the distance between two adjacent pixels is very short. This allows for a high resolution and clear image quality even at close viewing distances. Outdoor high resolution LED displays are suitable for various applications, such as advertising, digital signage, sports, entertainment, and events.

LED screens have developed rapidly in recent years, especially for outdoor applications. The most common type of outdoor LED display is the LED inline light, which has a large pixel pitch of 4 mm, 5 mm or more. This means the distance between two adjacent pixels is very long, which affects the image quality when viewed from a close distance.

However, outdoor LED displays are not only used for huge billboards in shopping malls and on highways, but also for various other purposes, such as advertising, digital signage, sports, entertainment, and events. As a result, people are increasingly expecting to see a high-definition viewing effect from outdoor LED screens. This has led to the trend of reducing the pixel pitch of outdoor LED displays.

Therefore, LED technology and manufacturing techniques have improved to meet the demand for high-resolution outdoor LED displays. The pixel pitch of outdoor LED screens has gradually decreased from P10 to P3, P2.5, and even P1.8 and P1.5. This means the distance between two adjacent pixels is very short, which allows for a clear image quality even at close viewing distances. For example, an outdoor P1.8 LED display uses SMD LED technology, which protects the LEDs from water, dust, and UV rays, and enhances the brightness and color uniformity of the display.

In the progress of technology and people’s continuous pursuit of display effect, such as outdoor advertising and other applications of outdoor LED display put forward higher requirements, not only high brightness, but also withstand the sun and rain, in order to achieve a wider perspective, more vivid colors and clearer details of the display. The birth of outdoor small–pitch, is to meet these needs of the people. With the packaging device is getting smaller and smaller, outdoor display began to small–pitch direction, the original is the use of inline package form, and then with the maturity of the technology, the table sticker began to be used in outdoor. Table stickers began to 5050 package, followed by the gradual emergence of 3535 package, and now the rise of the 2828 package. Packaging devices all the way to miniaturization, coupled with weathering performance has been an essential breakthrough, the table sticker display began to move from indoor to outdoor, which is the prototype of outdoor small-pitch development.

Fine-pitch LED display indoors has been widely used while outdoor Small–pitch displays have just started to develop, from the technology is not yet an essential breakthrough. rome is not built in a day, the development of outdoor small–pitch also needs a long time, after a lot of experimentation and verification.

 Advantages

 Outdoor small pitch LED display screen picture is clearer, better color reproduction, customer creativity show better, more and more by the media company and outdoor advertising owners love. It is not only an advertising medium, but also an intelligent interactive terminal, which draws the distance between the display and the viewer, so that the display is no longer high above, no longer let people can only “watch from afar and can not be close to play“, “grounded“ dissemination of information, eliminating the “rejection“ of the LED display. LED display “refuses people outside“ the sense of strangeness.

The pro–people display, not only strengthen the media dissemination effect, but also established the link between outdoor advertising and cell phones, such as through the QR code, micro letter, interactive and other ways of application of new technologies can enhance the influence of outdoor media, interactivity and media value.

Difficulties

 Indoor small pitch display has been developed very mature, it replaces the projection, DLP, LCD such as splicing large screen wall, in the industry to occupy part of the market. But the complex outdoor environment, for the development of small–pitch is a strict challenge. To do a good job of outdoor small–pitch LED display, you need to choose the surface–mounted LED devices, but the surface–mounted LED display brightness is low, and waterproof, moisture–proof, UV–resistant functional indicators do not meet the requirements of the harsh outdoor environment.

 Outdoor small pitch is now very hot, but in fact it still has a lot of problems, a lot of things are immature, but also need to go through a lot of experiments to test its decay time and aging and so on. Moreover, the chip of the outdoor display can not be made too small, if the chip is too small, it is not conducive to attenuation resistance. Especially for outdoor advertising display, a day will be used for about 15 hours, so there are many aspects to consider.

 In addition to technical issues, the price of the product is also one aspect, for outdoor advertising operators, outdoor small pitch LED display is much more expensive compared to the conventional outdoor LED display.

 Waterproof, heat dissipation and other performance is outdoor small pitch need to break through the technical field. The use of outdoor small–pitch display environment determines its waterproof, heat dissipation performance to be more reliable to ensure the long–term operation of outdoor LED media life requirements, and can not rely on the steel structure of the waterproof and heat dissipation design.

 In addition, for outdoor operators, in the pursuit of small pitch LED display, but also fully consider the operation of the screen later. The smaller the dot pitch of the display, the higher the resolution, and the higher the resolution, the higher the clarity of the screen, but for the outdoor screen without the need to use small pitch display to achieve the best display effect, if you follow the trend of the pursuit of small pitch, the use of the lamp beads per unit area will increase exponentially, and therefore the large screen power consumption will be increased significantly, resulting in serious operational pressure.

the summary

Outdoor posting just emerged, many companies encountered a lot of difficulties, but learn from the mistakes, there is a need to improve the problem, it is not a step forward, after a long time of experimentation, and now outdoor posting has gradually matured. By the same token, the development of outdoor small-pitch display is not overnight, it also needs to slowly mature step by step, more difficult than the development of indoor small-pitch, because the outdoor protection performance requirements are higher.

 From the perspective of future development, small pitch as a technology or a product development in outdoor applications have a lot of space. Even if there are still many technical bottlenecks, but it is undeniable that small pitch is an inevitable trend in the form of the industry. With the improvement of SMD process, the weather resistance of outdoor display has been greatly improved, and now the application of P4 products on the market is relatively successful.

Installing a digital billboard in a coastal area requires special care and attention. Coastal areas are prone to more rainfall, higher temperature, stronger wind and direct sunlight than inland areas. These factors can affect the performance and durability of the digital billboard. In this article, we will explore the 6 main factors to consider when installing a digital billboard in a coastal area. Let’s get started.

Factors to Consider When Installing a Digital Billboard in Coastal Area

Strong Windload

Wind can have a significant impact on the installation and performance of a high-rise digital billboard. A taller digital billboard is more exposed to strong wind, which can cause vibration and damage. The engineer needs to calculate the wind load accurately and design a stable installation.

Wind can also pose a risk during the installation process. The process needs to be well planned and executed with proper safety measures.

Brighter and stronger UV

Coastal areas have brighter sunlight and stronger ultraviolet rays. These can affect the quality and durability of a digital billboard. Bright sunlight can make the screen look dim, so the screen needs to have a high brightness level and a wide viewing angle. Ultraviolet rays can damage the screen surface, so the screen needs to have a coating that can protect it from ultraviolet rays.

High Environmental Temperature

Bright sunlight can make a digital billboard very hot, which can affect how well it cools itself down. If a display cannot get rid of the heat, it might overheat and stop working properly.

High Humidity.

Humidity is the moisture in the air. It is higher near the sea.

  • Metal corrosion. Salty water/moisture is more corrosive than freshwater because it contains more dissolved ions that can speed up the chemical reactions between cabinet metal and oxygen. This causes metal to rust faster and lose its strength.
  • Electronic components corrosion Water in the air can also corrode the printed circuit board (PCB) inside the display and make it stop working. To protect the PCB from moisture, we can apply a surface finish and a conformal coating. These can prevent corrosion and other problems.

Heavy Rainfall.

Coastal areas have brighter sunlight and stronger ultraviolet rays. These can affect the quality and durability of a digital billboard. Bright sunlight can make the screen look dim, so the screen needs to have a high brightness level and a wide viewing angle. Ultraviolet rays can damage the screen surface, so the screen needs to have a coating that can protect it from ultraviolet rays.

Environmental ruggedness

High humidity means more moisture in the air. This is common in coastal areas where the air comes from the sea. Moisture can damage the electronic parts of a digital billboard, such as the printed circuit board (PCB). The PCB controls the electricity flow in the LED screen. Moisture can cause corrosion and oxidation, which can make the LED screen stop working. To protect the PCB from moisture, we can apply a surface finishing during fabrication and a conformal coating during installation. These methods can also prevent other harmful effects from contaminants, fluid and ultraviolet rays.

conformal coating led display board

Our LED cabinets are crafted from fully aluminum frames, while the hinges and screws are made from 316 stainless steel to withstand the corrosive effects of sea winds. This durable construction ensures longevity and optimal performance, making these displays ideal for coastal or marine environments where exposure to salt and moisture is common.

  • 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.

LED Display Contrast Ratio Definition

According to the definition of industry-standard SJ/T11281-2007 “Light Emitting Diode (LED) Display Test Method,”Contrast is a term that describes how bright or dark the image on an advertising LED screen is. It is calculated by comparing the brightness of the white and black colors on the screen. The contrast ratio is a number that shows how much brighter the white is than the black.

For example, an LED display contrast ratio of 1000:1 means that the white is 1000 times brighter than the black. The higher the contrast ratio, the more clear and colorful the image is. The lower the contrast ratio, the more dull and blurry the image is.

Static and dynamic contrast ratio

: The contrast ratio can be measured in different ways, such as static contrast ratio and application contrast ratio. The static contrast ratio is measured in a completely dark room environment, and it is usually very high, as high as millions to one. The application contrast ratio is measured at an ambient illumination of 10±10% lx, and it is more realistic and practical. According to industry standards, an LED display application contrast ratio greater than or equal to 5000:1 is the highest level of C.

 Different Contrast ratios Among COB, GOB, SMD led displays

SMD LED Display: Black SMD LEDs VS White LED Screen.

Black SMD LED in small sizes, make them perfect for incorporation into instruments and devices. The smaller the chip size, the higher the contrast ratio of the LED display. This is because a smaller chip leaves more black space on the display, which reduces the brightness when the LED is off. Even though a smaller chip also reduces the brightness when the LED is on, the contrast ratio still increases significantly.

Black LEDs have a higher contrast ratio than white LEDs, which means they can produce darker blacks and more uniform colors. The contrast ratio of black LEDs is 8000:1, while the contrast ratio of white LEDs is 3000:1.

  • Power consumption: Black LEDs consume less power than white LEDs, which makes them more energy-efficient and eco-friendly. The power consumption of black LEDs is 350/m2, while the power consumption of white LEDs is 410/m2.
  • Brightness: White LEDs have a higher brightness than black LEDs, which means they can be more visible in bright environments. The brightness of white LEDs is Max. @2000cd/m2, while the brightness of black LEDs is Max. @1500cd/m2.
  • Display effect: Black LEDs can display black or gray colors more accurately and smoothly than white LEDs, which can cause distortion or noise in the same colors. Black LEDs have more stable and softer colors, although less bright than white LEDs.

LED Display Contrast Ratio: COB VS GOB

The contrast ratio of the COB led screen is higher than the SMD and GOB led screens. This is because the COB package does not use a bracket structure to support the chip device, which limits the size of the package body and the light-emitting pixel point. The COB package can use smaller chips according to different viewing needs, which increases the black area on the display and improves the contrast.

cob-led-display-visionpi-painting high contrast ratio copy

LED Display contrast ratio Flip chip COB vs Lateral Chip COB 

The LED display contrast ratio of the flip-chip is higher than the front-mounted chip. This is because the flip-chip does not have electrodes and bonding wires on the light surface, which occupy part of the area that should be light. The flip-chip also has a larger light-emitting area and a higher luminous efficiency. This makes the LED brighter when it is on and darker when it is off, which enhances the contrast.

High Contrast COB LED Display

As aforementioned, the importance of high contrast for mini LED displays is obvious. The combination of full flip-chip and COB packaging technology of the mini LED display is an outstanding contribution to improving the contrast. Therefore, a full flip-chip COB display will be the best solution for a high-contrast ultra-fine-pitch LED display.
