LED Displays: The “Pixel Universe” Behind Visual Magic

LED Displays: The “Pixel Universe” Behind Visual Magic

The stunning giant advertising screens in shopping malls, the stage screens synced with live concert footage, the wall-mounted surveillance screens in monitoring rooms… What kind of “pixel universe” lies behind these eye-catching LED displays?

Basic Logic: Pixels are “cells”

LED displays are composed of countless “pixels,” each of which is a combination of three red, green, and blue (RGB) LEDs. By controlling the light intensity of these three LEDs, 16.7 million colors can be blended (on a conventional full-color screen), bringing everything from landscapes to people to life. Fine-pitch screens (such as 1.2mm pitch) have denser pixel arrangements, resulting in fine detail even up close, making them ideal for indoor close-up viewing. Large outdoor screens have larger pitches (like 10mm) for greater clarity from a distance and greater wind, water, and sun resistance.
