LED Technology

At the core of an LED display pantallas wall are the light - emitting diodes. LEDs are semiconductor devices that emit light when an electric current passes through them. In a color LED display, a combination of red, green, and blue (RGB) LEDs is used to generate a wide spectrum of colors. Each pixel on the display is typically composed of multiple RGB LED chips. By varying the intensity of the red, green, and blue light emitted by these chips, different colors and shades can be produced.

When an electric current is applied to an LED, electrons in the semiconductor material are excited from the valence band to the conduction band. As these electrons return to their original energy levels, they release energy in the form of photons, which results in the emission of light. The color of the light depends on the energy bandgap of the semiconductor material used in the LED. For example, LEDs with a smaller energy bandgap emit red light, while those with a larger energy bandgap emit blue light. By precisely controlling the current flowing through each RGB LED chip, the LED display can achieve accurate color reproduction and display a wide range of visual content.

Digital Signal Processing

To display images, videos, and other digital content on an LED display pantallas wall, digital signal processing techniques are employed.
