Patent number: 10243176Abstract: A method for repairing a bank during manufacture of an organic EL display device when a bank defect portion is produced due to collapsing of a bank, a foreign particle, or the like. The method includes: detecting a defect portion of a lengthwise bank formed over a ground substrate; and when a defect portion is detected, forming, in each of adjacent concave spaces between which the lengthwise bank having the defect portion is located, a dam partitioning the concave space into a first space in a vicinity of the bank defect portion and a second portion not in the vicinity of the bank defect portion. The shape of the dam is configured so that in ejecting organic functional layer ink in each concave space with a nozzle head, there is an ink dropping point in each of the first space and the second space.Type: GrantFiled: August 6, 2015Date of Patent: March 26, 2019Assignee: JOLED INC.Inventors: Yoshiki Hayashida, Kazuhiro Kobayashi, Toshiaki Onimaru, Takayuki Shimamura

Patent number: 9818809Abstract: An examination is performed of whether or not a bank having a defect portion is present. When a bank having a defect portion is present, the bank having the defect portion is repaired by forming a dam in each of adjacent concave spaces between which the bank having the defect portion is located. A dam formed in a concave space partitions the concave space into a first space in a vicinity of the defect portion and a second space outside the vicinity of the defect portion. The dam, at a portion thereof with lowest height, satisfies (h/H)+0.1W?1.5, 0.5?(h/H)?2.0, and 5?W?50, where a ratio of the height h of the dam to a height H of the banks is denoted as h/H, and a width of the dam is denoted as W ?m.Type: GrantFiled: February 6, 2015Date of Patent: November 14, 2017Assignee: JOLED INC.Inventors: Kazuhiro Kobayashi, Toshiaki Onimaru, Yoshiki Hayashida, Takayuki Shimamura
