Alternating current light-emitting device
First Claim
1. A fabrication method for an alternating current light-emitting device, the fabrication method comprising the steps of:
- providing a substrate;
forming at least two active layers on the substrate;
forming a plurality of openings in the active layers such that a portion of the substrate is exposed through the openings;
covering a periphery of the active layers with a protective layer;
forming a plurality of conductive terminals through the protection layer so as to electrically connect to the active layers; and
forming a plurality of conductive structures on the exposed portions of the substrate in the openings, the conductive structures providing electrical connection with the active layers such that, after alternating current is applied to the active layers, the active layers take turns to emit light during positive and negative half cycles of alternating current.

Abstract
An alternating current light-emitting device and the fabrication method thereof is disclosed. The alternating current light-emitting device includes at least one alternating current micro-die light-emitting module formed on a substrate and composed of at least two micro-dies connected to one another. The micro-dies, each includes at least two active layers, are electrically connected by a conductive structure, such that the active layers of the micro-dies take turns emitting light during positive and negative half cycles of alternating current, thereby providing a full-scale light-emitting area for all-time light emission.
