Introduction to Micro-LED Diodes for Displays

Micro-LED diodes are a type of semiconductor device that emits light when an electric current is applied. They are significantly smaller than traditional LEDs and are capable of producing images with higher resolution and better contrast. The term "micro" refers to the size of the LED chips, which are typically in the range of 10 to 100 micrometers. This miniaturization allows for the creation of displays with pixel densities far beyond what is possible with current LCD and OLED technologies.

How Micro-LED Diodes Work

Micro-LED diodes operate on the principle of electroluminescence, where a semiconductor material emits light when an electric field is applied. The diode consists of a p-n junction, where electrons and holes recombine to release energy in the form of photons. The size of the micro-LED chips is crucial in determining the display's resolution, as smaller chips allow for more pixels to be packed into a given area.
