Abstract
A method for forming a light-emitting device of the present application comprises providing a wafer; forming a first plurality of light-emitting elements on the wafer; providing a first connection structure to connect each of the first plurality of light-emitting elements; and applying a current flow to one of the first plurality of light-emitting elements for testing at least one electrical property of the light-emitting element while no current flow is applied to the remaining of the first plurality of light-emitting elements.
Claims35
A method for forming a light-emitting device, comprising:
- providing a wafer;
- forming a first plurality of light-emitting elements on the wafer;
