Title:
PATTERN FORMATION DEVICE FOR CONDUCTIVE SUBSTRATE AND ITS METHOD
Document Type and Number:
Japanese Patent JP3902579
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pattern formation device for a conductive substrate applied to OLED manufacture and its method.
SOLUTION: The pattern formation device for the conductive substrate comprises an aperture, an electrode device with a plurality of electrode rings and the aperture, a plurality of ferromagnetic carrier beads, a feed unit providing organic light emitting powder stirred with the carrier beads by a feed roller and a magnetic roller and charged by friction, a movable conductive substrate comprising a flat plate and a conductive layer for covering it, a voltage supplying device for supplying voltage to a movable conducting device and the magnetic roller, at least one conductive roller connected with the voltage supplying device contacting with the conductive substrate under a condition of supplying voltage to the movable conductive substrate, and an electrode control device for controlling the voltage of the electrode ring so that an electric field and the organic light emitting powder adsorb or repel.
