Abstract
An electronic apparatus is provided. The electronic apparatus includes a substrate including a plurality of electrodes in contact with at least part of electrodes of a plurality of micro LEDs disposed on a transparent substrate at a first pitch to apply a current to micro LEDs of the plurality of micro LEDs disposed at a second pitch, a camera disposed opposite to the substrate based on the transparent substrate, and a processor configured to apply a current to the plurality of electrodes on the substrate, control the camera to capture an image of the plurality of LEDs including a light emitting micro LED according to current applying, obtain characteristic information of the light emitting micro LED based on the captured image, and determine a target substrate on which each of the plurality of micro LEDs is disposed based on the obtained characteristic information.
