Abstract
An alternating current light emitting device and the fabrication method includes forming one or more alternating current micro diode light emitting modules on a substrate, wherein the alternating current micro diode light emitting module has two micro diodes connected to one another, and each micro diode has at least two active layers and is electrically connected by a conductive structure, such that the active layers of each micro diode can take turns emitting light during the positive/negative half cycles of alternating current. A continuous and full-scale light emitting effect is thereby achieved.
