An LED screen is a display technology that uses an array of tiny LEDs to create visual output. LEDs are semiconductor devices that emit light when an electric current passes through them. LED screens offer vibrant colors, high contrast, and energy efficiency. They are widely used in various applications, including televisions, computer monitors, outdoor signage, stadium screens, and video walls. LED screens provide sharp and bright images with wide viewing angles, making them popular for both indoor and outdoor use.Here is a brief overview:
1. LED Chips: LED screens consist of numerous small LED chips that emit light when an electric current passes through them. These chips are typically made of semiconducting materials such as gallium arsenide or gallium phosphide.
2. LED Packaging: The LED chips are encapsulated or packaged to protect them and provide mechanical support. The packaging also helps to enhance the efficiency and performance of the LED by controlling the direction and intensity of the emitted light.
3. Pixel Structure: LED screens are composed of multiple pixels that make up the entire display. Each pixel contains several LED chips, including red, green, and blue (RGB) chips. By adjusting the intensity of each color, the screen can create a wide range of colors and shades.
4. Backlighting: In LED screens, a backlighting system is used to provide uniform illumination behind the pixels. This helps to improve the screen's brightness and contrast
