METHOD FOR MANUFACTURING AN LED EMISSIVE DISPLAY AND CORRESPONDING LED EMISSIVE DISPLAY

摘要

A method of manufacturing an emissive LED display device, including the steps of forming a plurality of chips, each including at least one LED and, on a connection surface, a plurality of hydrophilic electric connection areas and a hydrophobic area; forming a transfer substrate including, for each chip, a plurality of hydrophilic electric connection areas and a hydrophobic area; arranging a drop of a liquid on each electric connection area of the transfer substrate and/or of each chip; and affixing the chips to the transfer substrate by direct bonding, using the capillary restoring force of the drops to align the electric connection areas of the chips with the electric connection areas of the transfer substrate.
