Micro LED grip body and system having same for inspecting micro LED
The present invention relates to a micro LED grip body and a system having the same for inspecting a micro LED, the micro LED grip body having a vacuum-suction structure capable of being used for transferring a micro LED, thereby solving problems of micro LED transfer heads that have been proposed in the related art.
1. A micro LED grip body, comprising:
a porous member including an anodic oxide film having pores; and
a conductive layer provided on a surface of the porous member to prevent a generation of static electricity on the surface of the porous member,
wherein the porous member includes a suction region gripping micro LEDs and a non-suction region not gripping the micro LEDs, and
wherein the pores comprise first pores and second pores, the first pores are located in the suction region, the second pores are located in the non-suction region, and the first pores are configured to extend from top to bottom of the porous member.
2. The micro LED grip body of claim 1 , wherein the conductive layer is configured in a manner not to block the pores.
3. The micro LED grip body of claim 1 , wherein a micro LED brought into close contact with a surface of the conductive layer is gripped by a transfer head due to vacuum applied to the pores.
4. A micro LED grip body, comprising:
a porous member having pores; and
a conductive layer provided on a surface of the porous member to prevent a generation of static electricity on the surface of the porous member,
wherein the porous member includes a suction region with a through-hole gripping micro LEDs and a non-suction region not gripping the micro LEDs, and
wherein the through-hole is configured to extend from top to bottom of the porous member, and a diameter of the through-hole is configured to be larger than those of the pores.
5. The micro LED grip body of claim 1 , wherein the porous member includes a porous ceramic.
6. A micro LED grip body, comprising:
a porous member having pores, the pores comprising first pores and second pores;
a vertical conductive portion provided in some of the first pores of the porous member; and
a horizontal conductive portion connected with the vertical conductive portion,
wherein the porous member includes a suction region gripping micro LEDs and a non-suction region not gripping the micro LEDs, and
wherein the first pores are located in the suction region, the second pores are located in the non-suction region, and the first pores extend from top to bottom of the porous member.
7. The micro LED grip body of claim 6 , wherein the vertical conductive portion is provided in the suction region.
8. The micro LED grip body of claim 6 , wherein the porous member is configured as an anodic oxide film formed by anodizing a metal.
