Abstract
A micro LED display panel capable of simpler but more precise manufacture by pre-loading micro LEDs onto wafers which are then transferred to a substrate includes the substrate and light-emitting units. Each light-emitting unit includes a wafer unit and at least two micro LEDs on the wafer unit. The display panel includes pixel regions, each pixel region including at least three adjacent sub-pixel regions. Each sub-pixel region has one micro LED therein. Each micro LED of the light-emitting units is located in one sub-pixel region and the micro LEDs in each pixel regions emit light of different colors.
