Abstract: The present disclosure provides an apparatus for illumination inspection of micro LEDs. An apparatus for illumination inspection of micro LEDs includes a surface-contact probe making a surface contact, through an electrical resistive material, with a front surface of an LED assembly of multiple micro LEDs arranged forwardly and interconnecting LED electrodes at both ends of the micro LEDs, probe electrodes to be in line contact with one side and the other side of the surface-contact probe for supplying electric power, an imaging unit for photographing the LED assembly from an opposite surface of the surface-contact probe, to where the surface-contact probe is contacted, and a control unit for supplying electric power to the probe electrodes forwardly along the micro LEDs as aligned and for inspecting the micro LEDs illumination based on images of the LED assembly photographed by the imaging unit before and after supplying the electric power.
