What Problems Can Arise After Installing SMD Screens?

You may encounter several issues after installing SMD screens, especially if certain factors are not taken into account before installation. It’s important to be aware of these considerations to avoid future complications.

The majority of problems typically occur with outdoor SMD screens due to their exposure to harsh weather conditions whether extreme heat or cold. In contrast, indoor SMD screens are generally more protected and less prone to wear and tear.

In this discussion, I will focus primarily on outdoor SMD screens, as they are more vulnerable to environmental challenges and require extra attention during installation.

In Pakistan, SMD screens are often installed without properly accounting for key environmental factors. While some conditions can be assessed visually, others are either overlooked due to a lack of appropriate equipment or simply ignored during installation.

Humidity:

Humidity is frequently not considered, yet it can significantly impact both the display components and the structural integrity of the screen especially if iron materials are used. In areas with high humidity, such as regions near canals or rivers, this oversight can lead to corrosion and damage over time.

To mitigate this risk:

1) Aluminium cabinets should be used instead of iron to resist humidity-related corrosion.

2)If the display is mounted on poles, the poles should be regularly painted to preserve their strength and durability.

Air Pressure and Wind Resistance Considerations for SMD Display Installation:

When installing an SMD screen, it is crucial to evaluate the wind pressure in the area. Ignoring this factor can lead to structural damage, especially during windstorms. There are two common scenarios where wind pressure can have a significant impact:

Open Areas: If the display is installed in an open space without surrounding buildings, it is more exposed to direct wind pressure during storms, increasing the risk of damage.

Rooftop Installations: Displays mounted on top of buildings are often angled for better visibility. However, this height and angle also make them more vulnerable to high wind forces.

Solution:

To ensure stability and durability:

• Use high-gauge iron for the entire structure, including the display frame and supporting poles.
• The display should have a strong back support system made from heavy-duty materials to resist bending or flexing.
• The overall structure must be rigid enough to withstand high wind pressure without deformation.

As professionals in this field, we highly recommend seeking expert advice before installation. This helps you avoid costly damage and ensures your investment is protected SMD screens are not inexpensive items you can easily replace.

Fabrication Quality: A Critical Factor in SMD Screen Installation:

The structural framework of most SMD screens is typically made from iron and assembled through welding. If this fabrication work is carried out by an unskilled or unprofessional welder, your screen may face several serious risks.

Improperly welded joints can compromise the strength and durability of the structure. In particular, outdoor displays require watertight fabrication any poorly sealed joints or weak welds can lead to water seepage, which may cause long-term damage to both the structure and the screen components.

Furthermore, precision in the fabrication process is essential. If the basic frame is not constructed accurately, it can lead to alignment issues during module installation. This may result in:

• Uneven surfaces on the front of the screen
• Visible gaps between modules
• Poor overall visual quality

To avoid these issues, ensure your SMD screen structure is fabricated by experienced professionals who follow proper standards—especially for outdoor installations. Quality fabrication not only ensures long-term durability but also guarantees a seamless and visually appealing display.
Always seek professional company if you are planning to install in future.

Sunlight Exposure: A Crucial Consideration for Outdoor Displays

Outdoor SMD displays are naturally exposed to sunlight, but excessive and prolonged exposure can lead to a range of performance and durability issues—especially when the screen faces direct sunlight throughout the entire day.

Here are some potential problems caused by continuous sun exposure:

1. Reduced Brightness: Prolonged exposure to intense sunlight can cause the screen’s brightness to drop over time, reducing visibility.
2. Overheating: Constant high temperatures may lead to overheating, which affects overall performance and can shorten the lifespan of internal components.
3. Structural Weakening: Prolonged UV exposure can degrade the plastic components of the display modules, making them brittle and more likely to crack.
4. Thermal Expansion: In extreme cases, sustained heat may cause the iron structure to expand slightly, affecting the alignment and stability of the display.

Recommendation:

When selecting a location for an outdoor SMD display, avoid areas where it will be exposed to direct sunlight all day. Ideally, the screen should receive indirect sunlight or be installed in a position where it is shaded during the hottest parts of the day. This helps preserve both performance and structural integrity over time, and use proper ventilation system to keep temperature in control.

Conclusion:

Installing SMD screens especially in outdoor environments requires careful planning and consideration of several key environmental and structural factors. Neglecting aspects like humidity, wind pressure, sunlight exposure, and fabrication quality can lead to reduced performance, structural damage, and costly repairs. By working with experienced professionals and following proper installation standards, you can ensure your display remains durable, efficient, and visually effective for the long term. Always treat your SMD screen as a long-term investment and protect it accordingly.
