LED Technology

LED (Light Emitting Diode) technology, as a disruptive innovation in the field of illumination, revolves around the continuous development of LED chips. These tiny yet powerful chips are leading the lighting industry towards higher efficiency, energy-saving, and smarter directions. Here are commercial LED screen technologies, benefits and selection guide.

Basic Principles of LED Chips

LED chips are semiconductor devices that produce light by exciting solid-state emitting materials with electricity. The fundamental principle is the combination of electrons and positive holes releasing energy, which is emitted in the form of visible light. Different semiconductor materials and doping elements determine the color of the LED’s light emission. LED displays are divided into single-color, dual-color and full-color types.
