A LED video wall is a display technology that utilizes light-emitting diodes (LEDs) to create a large and seamless visual display. These video walls are composed of individual LED panels or modules that work together to form a cohesive and vibrant video or image. LED video walls are widely used in various applications, ranging from entertainment venues and advertising to control rooms and information displays.

Here are some key aspects and features of LED video walls:

1. LED Technology: LED stands for Light-Emitting Diode. LEDs are semiconductor devices that emit light when an electric current passes through them. In the context of video walls, LEDs are used as pixels to create the display.

2. Pixel Pitch: Pixel pitch refers to the distance between individual pixels on the LED display. Smaller pixel pitch values result in higher pixel density and better image quality, especially at closer viewing distances.

3. Modularity: LED video walls are modular, meaning they are made up of smaller individual panels or tiles that can be combined to create a larger display. This modularity allows for flexibility in size and configuration.
