Abstract
A light-emitting device includes: a substrate comprising a first side; multiple semiconductor stacks on the first side and separated from each other, wherein each of the multiple semiconductor stacks comprises a light extraction area; multiple electrode pads on the multiple semiconductor stacks; and a blocking layer between one of the semiconductor stacks and the substrate. The multiple semiconductor stacks comprises a first semiconductor stack and a second semiconductor stack, and the first semiconductor stack and the second semiconductor stack are independently controlled to emit light.
