With the widespread application of led display screens, its performance in outdoor advertising displays is particularly prominent and is favored by more and more users. Before, we mentioned the application precautions of outdoor LED display under high temperature in summer. Today Winbond Ying Optoelectronics will share with you how to do LED display solutions under low temperature conditions and what to pay attention to.
Outdoor led display
Our country has a vast territory, and there are big differences between the north and the south. In some areas, the low temperature is perennial. At this time, when we design the LED display solution, we have to focus on low temperature to ensure that the LED display can be used normally in the later stage.
1. Using ultra-low temperature power supply: low temperature power supply can achieve -40 degree ; start under -25 degree environment. Among them, when the low temperature environment is close to the temperature limit of the power supply (for example, the ultra-low temperature is used at -35 degree ), the power load of the power supply will be derated, and the derating rate is close to 50 percent .
2. Install a hot air curtain inside the LED display: make a closed channel inside the large screen, and install a hot air axial flow at the rear, and the working state of the hot air axial flow is realized by the temperature control system. When the temperature is lower than the set minimum ambient temperature, the hot air blower heats up and the screen temperature rises, and then the screen is turned on. When the temperature reaches the set temperature, the temperature control system cuts off the AC power supplying the hot air blower.

3. The "three-proof" treatment of power supply and PCB circuit boards. Outdoor LED electronic displays are in the open air for a long time. Therefore, PCB circuit boards, power supplies, and solder joints are required to be resistant to high and low temperatures, waterproof, fog, and corrosion. Winbond Ying Optoelectronics conducts comprehensive "three-proof" treatment on PCB circuit boards, components, and solder joints in outdoor electronic display systems. Circuit board three-proof paint is a special formulation of paint used to protect circuit boards and related products. The equipment is protected from environmental erosion, thereby improving and extending their service life, ensuring the safety and reliability of use.
The above are the issues that should be paid attention to in the display system solution of the led display at low temperatures. I hope to help you learn more about the knowledge of the led display.
