This self-illumination feature is one of the reasons LED screens are highly favored for both indoor and outdoor applications.
How LED Screens Work
LED screens are essentially made of multiple LED modules arranged in a grid. Each module contains several diodes, and the combination of red, green, and blue diodes forms pixels, which generate images. The brightness and contrast of these screens can be finely adjusted, allowing for vibrant displays that work in various lighting conditions. LED screens also offer lower power consumption compared to other screen technologies, making them an energy-efficient choice.
