    Abstract: A micro LED transfer head is proposed. The micro LED transfer head includes: a holding member including a holding region that holds a micro LED by means of vacuum holding force and a non-holding region that does not hold the micro LED; and a porous member provided on top of the holding member and having arbitrary pores, wherein the holding region includes: a first holding region; and a second holding region provided above the first holding region, formed to have a larger opening area than the first holding region, and communicating with the first holding region and the porous member, whereby the micro LED transfer head selectively transfers the micro LED.

    Abstract: The present invention relates to a micro LED structure and a method of manufacturing the same. More particularly, the present invention relates to a micro LED structure and a method of manufacturing the same, the micro LED structure including: a micro LED; a circuit board driving the micro LED; and an anisotropic conductive anodic oxide film provided between the micro LED and the circuit board to electrically connect the circuit board and the micro LED. According to the present invention, without applying an external force (thermocompression bonding) to the anisotropic conductive anodic oxide film, it is possible to electrically connect the circuit board and the micro LED. In addition, it is possible to obtain characteristics such as uniform conductivity in a vertical direction and heat dissipation.
