LED displays, or Light-Emitting Diode displays, are innovative visual communication tools that operate based on the principles of electroluminescence. Comprised of numerous tiny LED pixels, these displays generate light when an electric current passes through them. Each pixel has three main components: a semiconductor chip, electrodes, and a transparent encapsulation.
The semiconductor chip emits light when an electrical charge is applied. This chip is made from a combination of materials, such as gallium arsenide or gallium phosphide, which determine the color of light produced. The electrodes facilitate the flow of electric current into the chip, allowing it to emit light efficiently. Lastly, the transparent encapsulation protects the chip and electrodes from external elements, such as dust or moisture.
To produce different colors, LED displays employ a technique called “multiplexing.” By quickly alternating between other LEDs in red, green, and blue (RGB) combinations, a full spectrum of colors can be achieved. Additionally, controlling the brightness of each LED allows for dynamic and vivid displays.
With their energy efficiency, long lifespan, and ability to display high-resolution content, LED displays have become ubiquitous in various applications, including digital signage, television screens, and large-scale outdoor advertising.
