Micro led transfer head |
| abstract |
The present invention relates to a micro LED transfer head transferring micro LEDs from a first substrate to a second substrate. According to the present invention, vacuum pressure of a grip region where the micro LEDs are gripped is uniformized, so that the micro LED transfer head transfers the micro LEDs efficiently. In addition, the vacuum pressure is distributed over a grip surface where the micro LEDs are gripped, thereby improving efficiency of transferring the micro LEDs. |
