Jan 20, 2023 | General | 0 comments

The future of Micro LED For outdoor Advertising.

In recent years, the demand for high-resolution outdoor advertising displays has surged, with COB (Chip on Board) LED technology rising to meet this challenge. COB outdoor LED displays have made it feasible to achieve finer pixel pitches without compromising on brightness, setting a new standard in the industry. Unlike traditional LCD displays, COB technology provides enhanced versatility in screen size and shape, allowing for more creative and adaptive outdoor display solutions. This technological advancement is revolutionizing the way we experience outdoor advertising, offering unprecedented clarity and design flexibility.

Outdoor COB LED Display.

COB (Chip on Board) is a kind of LED display packaging technology. LED light-emitting chips are directly bonded to the module board with high precision and connected to driver components on the module board through special media for overall protection of the light-emitting surface. COB packaging  eliminates  the two key procedures  of  turning LED chips  into lamp beads and reflow soldering as compared to standard SMD packaging.

COB packing technology 

COB technology is a new and advanced way of making LED displays for outdoor use. It improves the performance and pitch of the displays, making them brighter, more uniform, and more durable. However, COB technology is also more costly and difficult to produce at the moment. which means that it is only suitable for high-end commercial display markets. COB technology is gradually gaining more popularity in the market, its ‘market share was less than 10% a few years ago.

COB VS SMD PACKING

Outdoor COB LED Display Features

  • Enhanced Durability: COB LED displays are known for their robustness, with the LEDs encased in a single module, which offers better protection against environmental factors like dust, water, and impact.
  • High-Resolution Imaging: The close packing of COB LEDs results in a seamless and dense pixel array, providing clearer and more detailed images, which are essential for outdoor displays.
  • Improved Heat Dissipation: COB technology typically has better thermal management due to its design, ensuring longer lifespan and consistent performance even under direct sunlight.
  • Wide Viewing Angles: With COB LEDs, viewers can enjoy wider viewing angles without experiencing color shifts or brightness loss, making the content visible from different perspectives.
  • Brighter Displays: COB LEDs can achieve higher brightness levels compared to other LED technologies, making them ideal for outdoor environments where sunlight readability is crucial.
  • Lower Power Consumption: Despite their brightness, COB LEDs can be more energy-efficient, translating into lower power consumption and operational costs.

COB LED Display Technology Development 2023

According to some data, in the first half of 2023, the sales of fine pixel LED (P2.5 and below) screens in China reached 7.33 billion, which is a little bit more than last year. COB technology had a big part in this, as its sales and display area grew a lot, much more than the other types of fine pitch LED screens. This shows that COB technology has changed from a small and special type of screen to a big and common one. It is ready to grow even more in technology and industry.

This change is related to how COB technology has improved and found new uses. Since it started in 2012, it has become better and better over the years. It has become cheaper and more popular, and it has more advantages than other types of LED screens. It is more reliable, more energy-saving, and more suitable for mini/micro LED technology. It can also meet the needs of new LED display products, such as LED all-in-one machines, business meetings, and smart education panels. These products need high-quality screens that are very clear and bright. Many COB brands have done very well in these markets.

LED Disply working in Low Temperature

Earth is a planet of extremes. Countries like Mali experience sweltering average temperatures as high as 83.89 °F (28.83 °C), while less than 3,500 kilometers away, the Swiss fight their way through the 6.1 °F winter chill.

The impact of  led display working in Extreme Weather

Outdoor LED displays in cold climates face the problem of different thermal expansion coefficients and uneven changes in the physical dimensions of their materials, such as masks, PCBs, module kits, and cabinet frames

  • Crack between module and module, cabinet and cabinet.
  • The shrinkage and breakage of the led modules’housing kits and cabinet frame.
  • The uneven shrinkage between the LED lamp and the mask, causing the LED lamp to loosen and display failure;
  • The potential dangers of water intrusion caused by the shrinkage of the waterproof rubber ring of the cabinet in low temperature.
  • The Power supply cease to work.
  • the protective(PVC) layer of the cable is easily broken, which will cause serious problems such as short circuit or even fire.

Selection of Low Temperature Resistant Raw Materials.

Adopt low-temperature resistant raw materials and devices, such as cold-resistant masks and bottom shell kits, low-temperature resistant waterproof glue, low-temperature power supply(meanwell) (can be started in an environment of -40℃; -25℃); Adopt low-temperature resistant cabinets, low-temperature resistant electronic devices and connectors.

specification lowe temperature led display power supply

Extra high protection ability

As outdoor fixed LED display works in outdoor environment for a long time, the PCB, power supply, soldering joints, etc. have high requirements for high and low temperature resistance, water resistance and corrosion resistance ability. It is recommended to carry out the coating and cold-proof treatment for PCB, components and parts, solder joints, etc., to protect the circuits from damage under the environments containing chemical substances (such as: fuel, coolant, etc.), vibration, moisture, salt spray, humidity and high temperature, low temperature conditions, thereby prolonging their service life.

Strong LED cabinets

The use of low-temperature resistant LED Cabinets: when the temperature reaches minus thirty degrees or even lower, the box of the LED display will shrink and deform, which will cause the gap between the box and the box to become larger, and even cause the peer lamps are not in the same straight line.

Heating Devices

Installing heating devices or fans inside the cabinets to keep the temperature within a reasonable range.

If the temperature is too low for the power supply to start, the screen will use an air curtain to warm up. Once the screen is warm enough, it will turn on normally. The temperature control system will turn off the air curtain when the temperature reaches the desired level.

Daily Maintenance in extrem cold weather.

To prevent damage to your led screen in very cold conditions, follow these tips:

  • The best option is to keep your led screen on all the time
  • If you can’t do that, at least use the stand-by mode when you are not using it
  • If you have to turn it off and it doesn’t turn on easily, then you may need to heat up the led screen gently

VISIONPI has developed two new products for outdoor fixed installation: the KINGKONG series and the CAMEL series. These products use high-quality raw materials to ensure they can adapt to different environments and protect themselves from damage. VISIONPI has a laboratory that is certified by CNAS, the national accreditation body of China. The laboratory tests every cabinet multiple times before they leave the factory. The tests check how well the products can work and store in low temperatures, and how they can handle changing temperatures. This way, the products can be used normally in cold places.
