Abstract

An adsorption device includes a magnetic plate and a limiting layer. A surface of the magnetic plate includes a first region and a plurality of second regions spaced apart from each other. The first region and each second region do not overlap with each other. The first region forms a magnetic pole of the magnetic plate, and each second region forms the opposite magnetic pole of the magnetic plate. The limiting layer covers the first region. Each second region is exposed to the limiting layer and configured for adsorbing a small-scale LED as a target object.
