How LED Displays Work
LED displays operate on a simple principle: when a voltage is applied to the semiconductor material, electrons recombine with holes, releasing energy in the form of light. This process is known as electroluminescence. The color of the emitted light depends on the materials used in the semiconductor. This technology not only allows for vibrant colors but also contributes to the longevity of the displays, as LEDs can last tens of thousands of hours without significant degradation in performance.
In a full-color LED display, red, green, and blue (RGB) LEDs are combined in various intensities to produce a wide spectrum of colors. By adjusting the brightness of each color, the display can create millions of different shades, resulting in vibrant and dynamic visuals. Moreover, advancements in LED technology have led to the development of features such as pixel pitch, which refers to the distance between the centers of two adjacent pixels. A smaller pixel pitch results in higher resolution and sharper images, making it ideal for applications where detail is crucial, such as in digital signage and high-definition video walls.
Applications of LED Displays
LED displays have found their way into various sectors, transforming the way information is communicated. Their versatility and efficiency make them ideal for numerous applications.
