Enhance Outdoor LED Display Maintenance

During the operation of outdoor LED displays, it is crucial to ensure that various factors causing damage are properly addressed. These factors include waterproofing, dustproofing, effective heat dissipation, anti-corrosion, anti-static, anti-lightning measures, and protection against small animals. Regular maintenance and inspection are also essential. The primary maintenance methods for outdoor LED display screens involve cleaning, fastening, visual inspection, and calibration. It is important to adhere to these necessary maintenance practices to ensure optimal performance and longevity of outdoor LED displays.

Cleaning of outdoor LED display

1. Clean the interior of the cabinet

For displays with a low protection level, particularly outdoor displays, it's important to be aware that dust can enter the device through ventilation holes, causing accelerated wear or damage to fans and other components. Dust can also impede heat dissipation and insulation performance by settling on the surface of internal control components. In humid weather, dust can absorb moisture from the air, causing a short circuit, and eventually, mold on the PCB board and electronic components. This can lead to reduced performance and failure of the device. Therefore, cleaning the display device is an essential aspect of maintenance work. It may seem like a simple task, but it's crucial to disconnect the power and handle the device with care while cleaning the dust inside.

2. Clean the surface of the screen

It's recommended to clean the outdoor LED display screen after prolonged usage to remove dust and impurities that have accumulated. First, acquire a high-quality cleaning kit that includes ingredients like electrolyte, high-purity distilled water, antistatic fluid, etc., to effectively eliminate stains and dust. While there are claims that a direct wash with clean water doesn't impact the screen, its cleaning capacity is limited, and dust will accumulate again. It's crucial to avoid spraying water directly onto the screen and instead apply a little cleaning solution to a cloth before wiping in the same direction. Ensure that before the process begins, the primary power cord is unplugged to avoid electric shock. To finish, use a vacuum cleaner to absorb any water marks or droplets left after the wet cleaning process, guaranteeing a dust and dirt-free LED display.

Fastening of outdoor LED display

The outdoor LED display large screen is a highly-power consuming device that requires invested attention and regular maintenance. Due to repeated use and thermal expansion and contraction, the wiring terminals of the power supply part may become loose, causing false connections. Furthermore, the plastic components next to it can become ignited by heat, and the signal terminals will weaken due to changes in the ambient temperature. Poor contact caused by moisture erosion can ultimately lead to equipment failure. Hence, to avoid such situations, regular checking of the tightness of the connectors is crucial. When adjusting fasteners, it is essential to exert uniform and appropriate force to ensure consistency in tightness. Our team recommends timely maintenance to ensure the device operates smoothly and efficiently, ensuring the satisfaction of all users.

Appearance inspection of outdoor LED display

Visually or measure and observe the appearance of outdoor LED display equipment. Including whether there are damage cracks on the outer surface of the equipment, whether the angle is inclined, whether the communication and distribution cable lines are normal, whether the fastener screws are loose and rusted, etc. For equipment with high protection level, although high reliability components and connectors are selected, its airtightness becomes the key factor, so it is necessary to regularly check the integrity of the seal. For outdoor screen steel structures, check the surface paint and corrosion. . At the same time, it is also necessary to regularly overhaul the heat dissipation and lightning protection equipment of the display screen.

Calibration of outdoor LED display

The theoretical lifespan of the LED display is 100,000 hours, but in fact, after a display runs for about 5,000 to 10,000 hours, there will be a difference in display uniformity, and inconsistent color and brightness attenuation will appear, resulting in the commercial value of the LED display. At this time, it is necessary to consider point-by-point correction.

Preparatory work before LED display calibration

1. Clean the LED display, remove the dust and stains on the light board and the mask, and avoid its influence on the brightness. If you need to replace the mask, please ensure that the color of the mask is the same as before, otherwise the display will be affected, especially in the daytime, and the correction will not improve much;

2. Replace defective modules: Some lamps are not bright, many dead lights, scanning is abnormal, the overall lamp is too dark (resistance may be wrong), cable or socket problems affect the display, etc. Make sure that the final display, scanning, and picture are normal, and there are no phenomena such as too dark, constant light, and continuous light before correction.

3. Receiving card upgrade: If the currently used receiving card does not support calibration or the loading points are not enough, it needs to be upgraded. Due to the risk of dead card in the upgrade of the receiving card, the customer needs to contact the control system company in advance for the upgrade and related processing.

If the large-area display screen is in operation, the operator should also pay attention to inspections to observe whether there are abnormal sounds, odors, abnormal lights, etc. If the display screen has not been used for a long time, it must be inspected in advance when it is put into use again. It should be noted that if the surface mount LED display is not used for a long time, the stability of the display will decrease. It is recommended to use it for at least 1 hour a week to reduce the erosion of air moisture on the display.

Reasonable use of LED display screens also includes playing suitable programs. Long-term playing of the same picture will lead to a large local light attenuation; long-term playing of high-brightness programs will cause various components to work at full capacity and accelerate aging; at the same time, from an economic point of view, It will also consume a lot of power and increase operating costs, so special attention should be paid when using it.
