Fundamental Components and Design

At their core, commercial LED displays consist of an array of light-emitting diodes arranged in pixels. Each pixel typically contains red, green, and blue (RGB) diodes that combine to produce a full spectrum of colors through additive color mixing. The density of these pixels, referred to as pixel pitch (measured in millimeters), directly impacts the resolution and clarity of the display.

LED modules are integrated into panels, which are networked and controlled by sophisticated electronics to render complex imagery and motion video. Drivers regulate current across LEDs to maintain brightness and color fidelity, while processing units manage content inputs via HDMI, DVI, or network streams.
