Notice and Maintenance Methods for Outdoor LED Display Screen and Display Module

Outdoor LED display temperature reduction, brightness and wide-angle usage considerations

The use of outdoor LED displays is different from indoor displays as outdoor displays are more sensitive to natural environmental factors.

Factors such as temperature, sunlight, dust, rain, etc., can affect the performance of outdoor LED displays. Therefore, it is essential to pay attention to the considerations regarding temperature reduction, brightness and wide-angle usage of outdoor LED displays.

Outdoor LED displays have a specific temperature range within which they can operate. Both excessively high and low temperatures can affect their functioning. Thus, it is necessary to install ventilation equipment to reduce temperature and ensure that the internal temperature of the screen does not exceed -10°C to 40°C. Axial flow fans can be installed above the screen's back to remove the heat generated.

As outdoor LED displays produce heat during their operation, it is crucial to pay attention to their cooling requirements to prevent any internal circuit damage.

Outdoor LED displays have certain distance limitations, hence requiring ultra-bright LED lights to ensure visibility from far away in bright ambient light conditions. Additionally, the material used for the LED display screen must be selected with care to protect against sunlight exposure.

Newly-developed wide-angle tubes are suitable for outdoor LED displays. These tubes have a wider viewing angle, offer pure colors, consistency, and extended life of over 10,000 hours. They have a square tube shape with a shading device casing surrounding the display medium.

The display medium is sealed with silicone, and the assembly is non-metallic, with an elegant, sturdy, and durable appearance. The screen is protected from direct sunlight, dust, water, high temperature, and circuit short-circuits.

Maintenance methods for outdoor LED display modules

Outdoor LED displays are becoming increasingly popular and require maintenance to increase their lifespan.

If multiple modules of the LED display flicker or do not light, check whether the signal direction of the first abnormal module is in proper contact with the power and signal lines.

If the module has no LED lights, it implies that there is no power supply input; check the power supply part. If there is a color issue, it means that the module has no signal input. Check whether the input end of the abnormal module's signal lines is in close contact, and perform multiple plugging and testing. If the problem persists, replace the faulty wire.

When a single module does not light up, check whether the power supply to the LED display module is adequate, mainly focusing on the power socket on the module.

If the entire module has inconsistent colors or mixed colors, it may be due to poor contact of the signal transmission line. Replug the signal connecting line or replace it with a tested line. If the replacement is ineffective, check whether it is an issue with the PCB board interface.

If a single light fails to light up on the outdoor LED display, use a multimeter to test the LED. If it is found to be damaged, replace it.
