Abstract
An electronic device is provided. The electronic device includes: a substrate, a first light-emitting element, and a second light-emitting element. The first light-emitting element is disposed on the substrate and configured to emit a first color light under a first current density when the substrate provides a first current to the first light-emitting element. The second light-emitting element is disposed on the substrate and configured to emit a second color light under a second current density when the substrate provides a second current to the second light-emitting element. The first current is equal to the second current, and the first current density is different from the second current density.
