Fixing problems for Outdoor LED Display screens

Fixing problems for Outdoor LED Display screens

• The LED display screen which installed outdoors, often exposed to the sun, rain, wind and dust, and the working environment is harsh. Electronic equipment being wet or severely damp can cause short circuit or even fire, cause failure or even fire, and cause loss;
• The LED display screen  may be attacked by strong electricity and strong magnetism caused by lightning.
• The ambient temperature changes greatly. When the display screen is working, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, so that the display system cannot work normally.
• The audience is wide, the viewing distance is long, and the field of vision is wide; the ambient light changes greatly, especially if it is exposed to direct sunlight.

There are environmental considerations that consider the most important points of Fixing problems for Outdoor LED Display screens:

Fixing problems for Outdoor LED Display screens

1. Working environment temperature range -20℃ -t≤50℃, 10%-90%RH;
2. Avoid using or storing in high temperature, high humidity, and high acid/alkaline/salt environment.
3. Keep away from combustibles, gas, dust, etc.
4. Avoid violent collisions during transportation and avoid violent collisions with objects;
5. When the ambient temperature is too high or the heat dissipation performance is not good, care must be taken to avoid using the screen for a long time;
6. After the LED display is in operation with humidity exceeding the set value, it will cause corrosion of components, or even short circuit, resulting in permanent damage.
7. It is strictly forbidden for water, iron powder and other conductive metal materials to enter the screen. The LED display should be placed in a low-dust environment as far as possible. Large dust spots will affect the display effect, and too much dust will damage the circuit. If you enter the water for various reasons, please cut off the power immediately, so that all parts can be completely dry before entering the screen.

Outdoor LED Displays must:

1. The screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, and once accumulated water occurs, it can be discharged smoothly.
2. Install lightning protection devices on LED displays and buildings. The main body and the shell of the display screen are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning can be discharged in time.
3. Install ventilation equipment to cool down so that the internal temperature of the screen is between -10°C and 40°C. An axial fan is installed on the top of the back of the screen to discharge heat.
4. The display medium adopts a new type of wide viewing angle tube, which has a wide viewing angle, pure color, consistent coordination, and a life span of over 100,000 hours.

The outer packaging of the display medium is currently the most popular rectangular tube with a cover, sealed with silicone, and no brutalized assembly, its appearance is exquisite and beautiful, sturdy and durable, with protection from direct sunlight, dust, water, high temperature, and circuit short circuit “Five defenses” features.

As the main carrier of video advertising, outdoor LED displays need high-definition display effects. This includes high resolution, high brightness, high contrast, etc. High resolution ensures that high-quality advertising images can be displayed well.

High brightness ensures that the image can be displayed clearly under direct sunlight. High contrast is the color of the image. Strong guarantee of uniformity and good image.

Low power consumption, energy saving and emission reduction

Outdoor LED displays should respond to government calls, and energy conservation and emission reduction should be implemented as an important standard in manufacturing, including product energy consumption, product dispersion performance, and the amount of steel required for product installation. its one of the most important points of Fixing problems for Outdoor LED Display screens.

Large viewing angle and wide viewing area

The main function of the outdoor LED display is to do advertising pictures. Therefore, allowing more audiences to see the screen is the primary goal of the outdoor LED display. It adopts a large viewing angle design to cover the viewing angle to the greatest extent.

High level of protection

Because it is used outdoors, the weather environment must be considered. Large outdoor LED screens generally have to reach IP68 protection level to be able to fully adapt to all kinds of bad weather. Ensure that the large outdoor LED screens have strong weather resistance and can be used for a long time. The customer’s profit reaches the maximum.

A good outdoor LED display screen must contain the above four elements at the same time. In addition to the outdoor advertising display solution, the advantage of the product is not only based on high-definition display, low power consumption, controllable viewing angle, IP65 protection level and other characteristics.

Also required to have an aesthetic design that does not affect the appearance of the building transparently high and can be unique to the display of outdoor advertising media.

The outdoor LED display screen is manufactured using high quality LED components that provide impressive brightness, contrast and color reproduction. Our outdoor LED screen has. For example, their IP65 waterproof rating means they are built to withstand all weather conditions.

Outdoor LED screens are much brighter than indoor LED screens. Outdoor LED displays provide bright, vibrant images even in direct sunlight. Which makes it ideal for stadiums and outdoor events. one of the most important points of Fixing problems for Outdoor LED Display screens.

Each of our external displays is available in a modular format that gives you the flexibility to create displays of any size. Therefore, options are available to access the front or back service depending on the installation. Our outdoor LED display is manufactured under strict quality standards, and undergoes a rigorous testing process before leaving the factory.

Moisture insulation for outdoor LED screens is One of the most important points of fixing problems for Outdoor LED Display screens:

• Use a professional waterproof paint

The use of matching paint can not only prevent circuit board damage, but also improve the service life of the product. This solution must be prevented during the production and construction of LED displays.

The principle of this scheme is to attach a layer of micron-thick protective coating to the surface of the circuit board by means of low-concentration micron coating technology. Due to the extremely low surface tension of this layer, the water droplets on the circuit board will slide off automatically, thus preventing moisture condensation.

• Electrical heating of outdoor LED screens

For electric heating, a moisture-proof device must be installed inside the LED screen to keep the temperature inside the screen higher than the ambient temperature. Keep the relative humidity inside as low as possible to completely prevent moisture condensation inside the board. also one of the most important points of Fixing problems for Outdoor LED Display screens.

• Regular cleaning

Regular cleaning

Regular cleaning of dust attached to the inner and outer part of the screen can also help better heat dissipation of the screen and reduce water vapor bonding.

However, outdoor LED display maintenance needs to emphasize not only humidity but also daily waterproof measures. Precise sealing construction helps reduce the risk of moisture and dust sticking to the inside and outside of the screen.
