Abstract
The micro light-emitting diode (LED) display matrix module of the disclosure includes a multilayer circuit layer, multiple micro LEDs, and an insulating flat layer. The multilayer circuit layer includes a top circuit layer and a bottom circuit layer. The bottom circuit layer includes multiple pads. The micro LEDs are disposed on the top circuit layer of the multilayer circuit layer and define multiple light-emitting units. Each of the light-emitting units includes three of the micro LEDs that are separated from each other. The light-emitting units are arranged in a matrix of m columns and n rows to define multiple pixel regions, and quantity of the pads is equal to 3m+n. An orthographic projection of each of the micro LEDs on the bottom circuit layer completely overlaps the corresponding pad. The insulating flat layer covers the top circuit layer of the multilayer circuit layer and the micro LEDs.
