Abstract
A device for mass transfer of Mini-LEDs based on array water jet-based ejection, including a planar motion platform, a vision camera, an array water jet-type ejection unit, a Z-axis motion platform, a blue membrane, an operation platform and a transfer substrate. The vision camera and the array water jet-type ejection unit are provided on a side of the planar motion platform. The array water jet-type ejection unit includes a water jet channel and a through-hole array. The Z-axis motion platform is provided at a side of the planar motion platform near the vision camera, and is configured for placement of the blue membrane. Multiple Mini-LED chips are bonded to the blue membrane. The operation platform is spacedly provided at a side of the Z-axis motion platform away from the planar motion platform.
