Title:
TRANSFER SYSTEM, TRANSFER POSITION DETERMINATION DEVICE, AND TRANSFER METHOD
Document Type and Number:
WIPO Patent Application WO/2022/185686
Kind Code:
A1
Abstract:
Provided are a transfer system, a transfer position determination device, and a transfer method with which it is possible to form a display that avoids the occurrence of irregularities while maintaining high yield of light emitting elements. Specifically, a transfer system 1 for transferring a plurality of light emitting elements 2 held on a holding means 3 onto a transferred substrate 4 is provided with: a light emitting property measuring unit 20 for measuring the light emitting property of each of the light emitting elements 2 being held on the holding means 3; a transfer position determination unit 30 which, on the basis of information about the light emitting property of each of the light emitting elements 2 on the holding means 3 obtained by the light emitting property measuring unit 20, creates information about the possibility of transfer with respect to each of the light emitting elements 2 and/or information about transfer positions on the transferred substrate 4; and a transfer unit 10 which, on the basis of the transfer position information created by the transfer position determination unit 30, transfers the light emitting elements 2 from the holding means 3 onto the transferred substrate 4.
