Abstract
A light-emitting device includes an emission array including a plurality of light-emitting elements and a partition wall. The emission array includes a first region and a second region adjacent to each other. The partition wall is configured to isolate the first region and the second region from each other, such that the partition wall at least partially defines the first region in the emission array. The first region is associated with a first emission factor and the second region is associated with a second emission factor, the second emission factor different from the first emission factor.
