    摘要: A detection device and a detection method are provided. The detection device includes a plurality of detection portions, a signal generator, and an optical component. The detection portions include a first detection electrode and a second detection electrode disposed at a same side. Different electrical signals provided by the signal generator are provided to a first electrode and a second detection electrode of a corresponding micro light-emitting device by the first detection electrode and the second detection electrode, respectively, to make a plurality of micro light-emitting devices emit light, and corresponding optical parameters are obtained by the optical component according to light-emitting conditions.
